ABSTRACT

Objective: To investigate the safety and efficacy of embedding the stump of gastroduodenal artery between the left lateral lobe of the liver and the left caudate lobe to prevent bleeding after laparoscopic pancreaticoduodenectomy. Methods: The clinical data of 41 patients who underwent laparoscopic pancreaticoduodenectomy at the second Hospital of Hebei Medical University from October 2021 to April 2022 were analyzed retrospectively.There were 27 males and 14 females, aged (63.0±9.2)years (range: 48 to 78 years), and the body mass index was (24.1±3.2)kg/m2 (range: 15.4 to 31.6 kg/m2). After routine laparoscopic pancreaticoduodenectomy, the stump of gastroduodenal artery was embedded between the left lateral lobe and the left caudate lobe of the liver, and the hepatic parenchyma of the left lateral lobe and the left caudate lobe were sutured with absorbable sutures.The occurrence and recovery of postoperative complications (pancreatic fistula, biliary fistula, postoperative abdominal bleeding, abdominal infection, liver abscess) were observed. Results: All the operations of 41 patients were completed successfully.The operation time was (277.5±52.0) minutes (range: 192 to 360 minutes). The entrapment time of gastroduodenal artery stump was (3.1±0.6) minutes (range: 2.3 to 4.2 minutes), and the intraoperative blood loss (M(IQR)) was 300 (200) ml (range: 50 to 800 ml).The results of ultrasound examination of hepatic artery on the first day after operation showed that the blood flows of hepatic artery were unobstructed.Postoperative pancreatic fistula occurred in 3 cases, including grade B pancreatic fistula in 2 cases (1 case with abdominal infection) and biochemical leakage in 1 case. Three patients with pancreatic fistula were discharged successfully after continuous abdominal drainage. There was no biliary fistula, abdominal bleeding, abdominal infection, liver abscess or postoperative liver dysfunction. Conclusion: The encasement of the gastroduodenal artery stump by the left outer and left caudate lobes of the liver may be an effective way to prevent bleeding from the rupture of the gastroduodenal artery stump after laparoscopic pancreatoduodenectomy, which is easy and safe to perform.

ABSTRACT

Abstract Background: Tranexamic acid was studied in four different dosage regimens and their efficacy was compared for perioperative blood loss reduction, blood transfusion requirements and deep vein thrombosis (DVT) complication. Methods: Two hundred patients undergoing major orthopedic procedures were divided into five groups containing 40 patients each: Placebo, low dose (bolus 10 mg kg-1), low dose + maintenance (bolus 10 mg kg-1 + maintenance 1 mg kg-1 hr-1), high dose (bolus 30 mg kg-1) and high dose + maintenance (bolus 30 mg kg-1 + maintenance 3 mg kg-1 hr-1). Surgical blood loss was measured intraoperatively and drains collection in the first 24 hours postoperatively. Blood transfusion was done when hematocrit falls less than 25%. DVT screening was done in the postoperative period. Results: The intraoperative blood loss was 440 ± 207.54 mL in the placebo group, 412.5 ± 208.21 mL in the low dose group, 290 ± 149.6 ml in the low dose plus maintenance group, 332.5 ± 162.33 mL in the high dose group and 240.7 ± 88.15 mL in the high dose maintenance group (p < 0.001). The reduction in postoperative blood loss in the drain for first 24 hours was 80 ± 44.44 mL in the placebo group, 89.88 ± 44.87 mL in the low dose group, 56.7 ± 29.12 mL in the low dose plus maintenance group, 77.9 ± 35.74 mL in the high dose group and 46.7 ± 19.9 mL in the high dose maintenance group (p < 0.001). DVT was not encountered in any patient. Conclusion: Tranexamic acid was most effective in reducing surgical blood loss and blood transfusion requirements in a low dose + maintenance group.


Resumo Justificativa: O ácido tranexâmico foi avaliado em quatro esquemas com diferentes posologias, comparando-se a eficácia de cada esquema quanto a redução na perda sanguínea perioperatória, necessidade de transfusão sanguínea e ocorrência de Trombose Venosa Profunda (TVP). Método: Duzentos pacientes submetidos a procedimentos ortopédicos de grande porte foram divididos em cinco grupos de 40 pacientes de acordo com o esquema de administração de ácido tranexâmico: grupo placebo, grupo baixa dose (bolus de 10 mg.kg-1, grupo baixa dose e manutenção (bolus de 10 mg.kg-1 + manutenção de 1 mg.kg-1.h-1), grupo alta dose (bolus de 30 mg.kg-1), e grupo alta dose e manutenção (bolus de 30 mg.kg-1 + manutenção de 3 mg.kg-1.h-1). A perda sanguínea cirúrgica foi medida no intraoperatório. Além disso, nas primeiras 24 horas pós-operatórias, foi medido o volume de sangue coletado no dreno. Era realizada transfusão de sangue se o valor do hematócrito fosse inferior a 25%. Foi realizada avaliação quanto à ocorrência de TVP no pós-operatório. Resultados: A perda sanguínea intraoperatória foi de 440 ± 207,54 mL no grupo placebo, 412,5 ± 208,21 mL no grupo baixa dose, 290 ± 149,6 mL no grupo baixa dose e manutenção, 332,5 ± 162,33 mL no grupo alta dose, e 240,7 ± 88,15 mL no grupo alta dose e manutenção (p < 0,001). A redução na perda sanguínea pós-operatória pelo dreno nas primeiras 24 horas foi de 80 ± 44,44 mL no grupo placebo; 89,88 ± 44,87 mL no grupo baixa dose, 56,7 ± 29,12 mL no grupo baixa dose e dose de manutenção, 77,9 ± 35,74 mL no grupo alta dose e 46,7 ± 19,9 mL no grupo alta dose e manutenção (p < 0,001). TVP não foi observada em nenhum paciente. Conclusão: O ácido tranexâmico administrado em baixa dose combinado à manutenção foi mais eficaz em reduzir a perda sanguínea cirúrgica e a necessidade de transfusão de sangue.

ABSTRACT

Abstract Introduction: Tranexamic Acid (TXA), an antifibrinolytic that inhibits the fibrinolytic activity of plasmin is used to decrease perioperative blood loss and transfusion requirements in orthopedic surgery. The aim of our study was to compare postoperative bleeding in two intra-articular doses (1 g and 2 g) of tranexamic acid in adult patients undergoing unilateral total knee replacement. Method: We conducted a single-operator, randomized, and controlled, double-blind study in two groups. The G1 group received 1 g of intra-articular TXA and the G2 group 2 g of intra-articular TXA. Both groups received 15 mg kg-1 IV before the surgical incision (TXA induction dose) and then 10 mg kg-1, orally, 6 and 12 hours after the induction dose of TXA.The primary endpoint was bleeding measured by blood loss in postoperative drainage. Secondary outcomes were change in hemoglobin and hematocrit levels on the first and third postoperative days, and the need for transfusion during hospitalization. Results: In total, 100 patients were randomized, and 100 were included in the analysis. Blood loss in postoperative drainage was similar in both groups (200 ± 50 vs. 250 ± 50 mL, G1 and G2 groups respectively). Change in hematocrit and hemoglobin values (% of change) between preoperative and day 3 were not statically significant between groups G1 and G2 (18 ± 5 vs. 21 ± 4; 21 ± 7 vs. 22 ± 5 respectively). No patients received blood transfusion. Conclusions: Our study did not show superiority of 2 g of intra-articular tranexamic acid compared to 1 g.ClinicalTrials.gov Identifier NCT04085575


Resumo Introdução: O Ácido Tranexâmico (TXA), agente antifibrinolítico que inibe a atividade fibrinolítica da plasmina, é usado para reduzir a perda sanguínea perioperatória e a necessidade de transfusão em cirurgia ortopédica. O objetivo do estudo foi comparar o efeito de duas doses intra-articulares (1 g e 2 g) de ácido tranexâmico no sangramento pós-operatório de pacientes adultos submetidos a prótese total unilateral de joelho. Método: Realizamos estudo com operador único, randomizado, controlado e duplo-cego em dois grupos. O grupo G1 recebeu 1 g de TXA intra-articular e o grupo G2, 2 g de TXA intra-articular. Os dois grupos receberam 15 mg.kg-1 IV antes da incisão cirúrgica (dose de indução de TXA) e 10 mg.kg-1 por via oral, 6 e 12 horas após a dose de indução de TXA. O desfecho primário foi o sangramento medido pela perda sanguínea na drenagem pós-operatória. Os desfechos secundários foram alteração nos níveis de hemoglobina e hematócrito no primeiro e terceiro dias de pós-operatório e necessidade de transfusão durante a hospitalização. Resultados: Cem pacientes foram randomizados e 100 foram incluídos na análise. A perda sanguínea pela drenagem pós-operatória foi semelhante nos dois grupos (200 ± 50 mL vs. 250 ± 50 mL, grupos G1 e G2, respectivamente). A variação nos valores de hematócrito e hemoglobina (% de variação) entre o pré-operatório e o dia 3 não foi estatisticamente significante entre os grupos G1 e G2 (18 ± 5 vs. 21 ± 4; 21 ± 7 vs. 22 ± 5, respectivamente). Nenhum paciente recebeu transfusão de sangue. Conclusões: O estudo não mostrou superioridade na dose de 2 g de ácido tranexâmico intra-articular em comparação à dose de 1 g.

ABSTRACT

Abstract Introduction: Packing of the nasal cavity has traditionally been used for postoperative bleeding control and decreasing synechia formation in patients undergoing nasal surgeries. Although absorbable nasal packing has been gaining popularity in the recent years, nonabsorbable nasal packing is still often used in nasal surgeries in various parts of the world. It is known to be associated with pain and discomfort especially upon and during removal, and previous reviews have only evaluated the effects of local anesthetic infiltration of nasal packing in septal surgeries. Objective: To evaluate the effect of infiltrating nasal packing with local anesthetics in postoperative pain and anxiety following sinonasal surgeries Materials and methods: We searched the PubMed and Embase databases from their earliest record to April 27, 2019, randomized controlled trials and prospective controlled trials for review, and included only randomized controlled trials for data analysis. We included studies using topical anesthetics-infiltrated nasal packing following sinonasal surgeries and evaluated the effectiveness compared to placebo packing in pain reduction during postoperative follow up, as well as the effectiveness in anxiety reduction. Results: Among 15 studies included for review, 9 studies involving 765 participants contributed to the meta-analysis. In terms of pain reduction, our analysis showed significant standard mean differences regarding effectiveness at postoperative 1, 12, 24 h interval for all surgical groups combined, in the sinus surgery group, as well as during nasal packing removal. There was no consistent evidence to support the effectiveness in anxiety reduction. Conclusions: Our study supports anesthetics infiltration of nasal packing as an effective method in managing pain in patients with nasal packing after sinonasal surgeries. However, the level of evidence is low. More high-quality randomized controlled trials are needed to establish its effectiveness in reducing anxiety. We believe this review is of great clinical significance due to the vast patient population undergoing sinonasal surgeries. Postoperative local hemorrhage remains the greatest concern for ear nose and throat surgeons due to the rich vasculature of the nose and sinuses. Sinonasal packing provides structural support and serves as an important measure for hemostasis and synechia formation. Although absorbable packing has been gaining popularity in the recent years, nonabsorable packing materials are still used in many countries due to lower cost. Infiltration of nasal packing with local anesthetic provides a solution to the discomfort, nasal pressure and nasal pain experienced commonly by the patients as evidenced by our analysis.


Resumo Introdução: O tamponamento da cavidade nasal tem sido usado tradicionalmente para controle do sangramento pós-operatório e diminuição da formação de sinéquia em pacientes submetidos a cirurgias nasais. Embora o tamponamento nasal absorvível tenha ganhado popularidade nos últimos anos, o tampão nasal não absorvível ainda é frequentemente usado em várias partes do mundo. Sabe-se que o tamponamento está associado a dor e desconforto, especialmente na sua remoção, e revisões anteriores avaliaram apenas os efeitos do tampão com anestésico local em cirurgias do septo nasal. Objetivo: Avaliar o efeito do tamponamento nasal infiltrado com anestésicos locais na dor e ansiedade pós-operatórias após cirurgias nasosinusais. Material e métodos: Para a revisão, pesquisamos nos bancos de dados PubMed e Embase desde o registro mais antigo até 27 de abril de 2019, incluímos ensaios clínicos controlados e randomizados, a ensaios clínicos prospectivos controlados e apenas ensaios clínicos controlados e randomizados para análise de dados. Incluímos estudos que usaram tamponamento nasal infiltrado com anestésicos tópicos após cirurgias nasosinusais e avaliamos a eficácia em comparação com o tamponamento com placebo na redução da dor durante o acompanhamento pós-operatório, bem como os efeitos na redução da ansiedade. Resultados: Entre os 15 estudos incluídos, 9, que envolveram 765 participantes, contribuíram para a metanálise. Em termos de redução da dor, nossa análise mostrou diferenças médias padrão significantes em relação à eficácia no pós-operatório nos intervalos de 1, 12, 24 horas para todos os grupos cirúrgicos combinados, no grupo da cirurgia sinusal e durante a remoção do tamponamento nasal. Não houve evidências consistentes para apoiar a eficácia na redução da ansiedade. Conclusões: Nosso estudo apoia o uso de tamponamentos nasais infiltrados com anestésicos locais como um método eficaz no tratamento da dor em pacientes após cirurgias nasosinusais. No entanto, o nível de evidência é baixo. São necessários mais ensaios clínicos randomizados de alta qualidade para estabelecer sua eficácia na redução da ansiedade. Acreditamos que esta revisão seja de grande significado clínico devido à vasta população submetida a cirurgias nasosinusais. A hemorragia local pós-operatória continua a ser a maior preocupação para os cirurgiões otorrinolaringológicos devido à rica vasculatura do nariz e seios nasais. O tamponamento nasosinusal fornece suporte estrutural e serve como uma medida importante para a hemostasia e formação de sinéquias. Embora o tamponamento absorvível tenha ganhado popularidade nos últimos anos, os materiais de tamponamento não absorvíveis ainda são usados em muitos países devido ao menor custo. A infiltração do tamponamento nasal com anestésicos locais fornece uma solução para desconforto, pressão e dor nasal comumente referida pelos pacientes, como evidenciado por nossa análise.

ABSTRACT

Abstract Introduction: After post-septoplasty nasal packing removal, a certain proportion of nasal secretion occurs, leading to local and sometimes systemic infections. Objective: The aim was to determine if standardized dry ivy leaf extract application after nasal packing removal influences the reduction of nasal secretion and diminish the occurrence of local infections. Methods: The study included 70 post-septoplasty patients (divided into two equal groups) whose nasal packing was removed on the third day after the procedure. Group I was treated with standardized dry ivy leaf extract syrup along with regular nasal irrigation for the five days after the nasal packing removal whereas the Group II had only nasal lavage. On the sixth day after nasal packing removal, the quantity of nasal secretion was determined using a visual analog scale and nasal endoscopic examination. Results: The group treated with standardized dry ivy leaf extract syrup had significantly lesser nasal secretion both by subjective patients' assessment (p < 0.001) and by nasal endoscopic examination (p = 0.003). The post-surgical follow up examination on the sixth day after nasal packing removal showed no development of local infection in the Group I, while in the Group II a local infection was evident in five patients (14.29%) and antibiotic therapy was required. Conclusion: The use of the standardized dry ivy leaf extract after nasal packing removal significantly lowers the proportion of nasal secretion.


Resumo Introdução: Após a remoção do tampão nasal pós-septoplastia, ocorre produção de secreção nasal, predispondo infecções locais e, por vezes, sistêmicas. Objetivo: O objetivo foi determinar se a aplicação do extrato padronizado de folhas de hera seca após a remoção do tampão nasal influencia a redução da secreção nasal e diminui a ocorrência de infecções locais. Método: O estudo incluiu 70 pacientes pós-septoplastia (divididos em dois grupos iguais) cujo tampão nasal foi retirado no terceiro dia após o procedimento. O grupo I foi tratado com xarope padronizado de extrato de folha seca de hera juntamente com irrigação nasal regular por cinco dias após a remoção do tamponamento nasal, enquanto ao grupo II foi recomendado apenas lavagem nasal. No sexto dia após a remoção do tampão nasal, a quantidade de secreção nasal foi determinada pela escala EVA (escala visual analógica) e pelo exame endoscópico nasal. Resultados: O grupo tratado com xarope de extrato seco de folhas de hera apresentou secreção nasal significativamente menor tanto pela avaliação subjetiva dos pacientes (p < 0,001) quanto pelo exame endoscópico nasal (p = 0,003). O exame de acompanhamento pós-cirúrgico no sexto dia após a remoção do tampão nasal não mostrou desenvolvimento de infecção local nos pacientes do grupo I, enquanto que no grupo II, cinco apresentaram sinais de infecção local (14,29%) com necessidade de antibioticoterapia. Conclusão: O uso do extrato padronizado de folhas secas de hera após a remoção do tampão nasal reduz significativamente a produção de secreção nasal.

ABSTRACT

Abstract Objective: To evaluate if lower activated coagulation time (ACT) value after neutralization than preoperative ACT value was effective in reducing bleeding, operative times, and post-operative transfusions in patients underwent coronary artery bypass grafting (CABG). Methods: Retrospective selection of 398 patients from January 2014 to May 2017. Patients were divided into 2 groups according to final ACT after neutralization: A - final ACT lower than preoperative ACT; and B - final ACT higher than or equal to preoperative ACT. Hemostatic time, intraoperative blood loss, ACT after final neutralization, mediastinal blood loss, and transfusion requirements were observed. Results: The hourly blood loss in the Group A was generally lower than in the Group B at first 3 hours, which has significant difference (P<0.05). However, there was no difference after 3 hours between the two groups. Operative time, intraoperative blood loss, mediastinal blood loss, transfusion requirements, and drainage in the first postoperative 12 hours in the Group A were lower than in Group B, which has significant difference (P<0.05). Conclusion: As a result, final ACT values lower than pre-heparinization ACT values are safe and lead to lower operative times, bleeding, and post-operative transfusions.

ABSTRACT

Abstract Introduction: Patients with acute coronary syndrome usually receive dual antiplatelet therapy (DAPT) (usually clopidogrel + aspirin) prior to coronary catheterization, and approximately 10% of these patients require coronary artery bypass grafting (CABG). DAPT has favorable effects on prevention of thrombus formation, but it can have deleterious effects on surgical hemostasis. Anaemia, if present, gives additional risk to such patients. The aim of this study was to examine if DAPT affects postoperative bleeding in patients with haemoglobin levels above 110 g/L, who underwent urgent or emergent CABG, less than five days after stopping DAPT therapy. Methods: Data were collected prospectively on 122 CABG patients, operated by a surgical team from March 2008 to August 2013. Patients were stratified into two groups: group 1 received DAPT within 5 days of CABG (n=65), and group 2 where DAPT was discontinued for more than 5 days prior to CABG (n=57). All patients were diagnosed with acute coronary syndrome preoperatively, and all of them had haemoglobin levels above 110 g/L. Patients who needed reoperation, combined procedures, or off-pump revascularization were excluded. Results: There was no hospital mortality. Mean chest tube losses after the surgical revascularization did not differ significantly, but group 1 received a higher quantity of transfused red blood cells and platelets. Conclusion: Urgent and emergent surgical revascularization using extracorporeal circulation in patients with acute coronary syndrome whose preoperative haemoglobin levels are above 110 g/L is a safe and effective procedure. We suggest that, where indicative, one may perform CABG in less than 5 days after the clopidogrel discontinuation.

ABSTRACT

Objective: To compare the intravenous boluses and intravenous continuous infusion of tranexamic acid [TXA] to reduce postoperative bleeding in cyanotic congenital heart disease surgeries


Study Design: Single-blinded randomised clinical trial


Place and Duration of Study: Anaesthesia Department, The Aga Khan University Hospital, Karachi, from July 2016 to April 2017


Methodology: Sixty patients of cyanotic congenital heart disease, undergoing either palliative or corrective surgery involving cardiopulmonary bypass [CPB], were recruited. These 60 patients were divided randomly into two groups. The infusion group received intravenous infusion of TXA at 5 mg/kg/hour while the bolus group received three intravenous boluses of 10 mg/kg after induction, after going to bypass and after protamine reversal. Data was collected through predesigned proforma. There were two primary outcomes: postoperative bleeding in the first 24 hours, and chest closure time


Results: Postoperative bleeding was 13.94 [10.27-20.18] ml/kg in the first 24 hours in infusion group and 15.05 [9.04-23.50] ml/kg in the bolus group. Chest closure time was 38.5 [25-45] in infusion group and 30 [20-46.25] minutes in the bolus group. There was no statistically significant and clinical difference between both groups regarding postoperative bleeding in the first 24 hours and chest closure time


Conclusion: These infusion and bolus groups had comparable postoperative bleeding and chest closure time

ABSTRACT

Abstract Given the growing trend towards medical indications for continuous use of anticoagulants, the number of patients on these medications continues to rise. The management of patients on oral anticoagulants requiring oral surgical procedures has aroused much controversy. Changes in an anticoagulation regimen are associated with an increased risk of thromboembolism. However, it seems logical and advantageous for the patients' health if surgery could be performed without any change to the anticoagulation therapy. In dentistry, high-power lasers have been poorly explored in this field. The hemostatic properties of high-power lasers could be helpful during oral soft tissue surgeries in anticoagulated patients. The aim of this study was to compare bleeding time in anticoagulated rats after lingual frenectomy performed with a scalpel or diode laser with bleeding time in healthy animals. Twenty-four male Wistar rats were assigned to four groups (n = 6): (CS) Control-Scalpel Surgery; (AS) Anticoagulated-Scalpel Surgery; (CL) Control-Laser (diode laser 810 nm/1.5 W) Surgery; and (AL) Anticoagulated-Laser Surgery (diode laser 810 nm/1.5 W). Warfarin administration was used to induce anticoagulation. Blood was blotted every 30 seconds with filter paper until bleeding stopped to verify bleeding time. Two blinded researchers performed the surgeries and collected the bleeding time data. Diode laser surgery led to complete hemostasis in rats during and after lingual frenectomy. Zero bleeding was assessed during surgeries and after diode laser surgeries in anticoagulated rats. Laser-induced hemostasis offered an alternative solution to the controversial issue of intraoperative and postoperative bleeding control in patients on anticoagulation therapy.

ABSTRACT

ABSTRACT Background: Stapled hemorrhoidopexy is a common treatment for grade 3 hemorrhoids. Patients with conditions that increase the risk of bleeding, as cardiac stents usage with clopidogrel bissulfate and liver cirrhosis, should receive an extra care in surgical procedures due to the high risk of bleeding. For this reason and for patients with third degree hemorrhoids we propose the use of stapled hemorrhoidopexy followed by the use of biological glue. Aim: Assess surgical outcomes in patients with hemorrhoids and high risk of bleeding submitted to stapled hemorrhoidopexy followed by biological glue. Methods: Between 2005 and 2015, 22 patients were analyzed, in a retrospective cohort study. Results: From 22 patients submitted to stapled hemorrhoidopexy followed by the use of biological glue, only one (4.5%) presented bleeding in the surgical postoperative. Patients do not have any other complications and pain in the postoperative period. The median (IQR) operation duration was 55 (12) min and the median (IQR) length of hospital stay after surgery was 3 (2) days. Conclusion: Patients with high risk of bleeding submitted to stapled hemorrhoidopexy followed by the use of biological glue presented very low rates of bleeding in the postoperative period.


RESUMO Racional: Procedimento para o prolapso hemorroidário é uma forma de tratamento comum para hemorróidas de grau 3. Pacientes que apresentem condições que aumentam o risco de sangramento, como o uso de stents cardíacos associado ao uso de clopidogrel e cirrose hepática, devem receber cuidado redobrado em procedimentos cirúrgicos, devido ao alto risco de sangramento. Por esta razão é aqui proposto o procedimento para prolapso hemorroidário seguido da aplicação de cola biológica em pacientes com hemorróida de grau 3. Objetivo: Avaliar os desfechos cirúrgicos em pacientes com hemorróida de grau 3 e alto risco de sangramento submetidos ao procedimento para o prolapso hemorroidário seguido da aplicação de cola biológica. Métodos: Entre 2005 e 2015, 22 pacientes foram analisados, em estudo coorte retrospectivo. Resultados: Dos 22 pacientes submetidos ao procedimento para o prolapso hemorroidário seguido pelo uso de cola biológica, apenas um (4.5%) apresentou sangramento no pós-operatório. Os pacientes não apresentaram nenhuma outra complicação ou dor no período pós-operatório. O tempo mediano da operação foi de 55 (12) min e a média do tempo de internação hospitalar foi de três (2) dias. Conclusão: Os pacientes com alto risco de sangramento submetidos ao procedimento de prolapso hemorroidário seguidos pela aplicação da cola biológica apresentaram baixa taxa de sangramento.

ABSTRACT

Abstract Introduction Nasal packing after endoscopic sinus surgery is used as a standard procedure. The optimum solution to minimize or eliminate all disadvantages of this procedure may be accomplished using biodegradable packs. Objective The aim of this study was to compare patient satisfaction and clinical outcome associated with absorbable and non-absorbable packing after FESS. Methods In total, 50 patients were included in a prospective, double-blind, randomized trial. One side was packed with polyurethane foam, while the opposite side was packed with gauze packing. On the 2nd, 10th, and 30th postoperative day, the patients were questioned with the aid of a visual analog scale. The standardized questionnaires for bleeding, nasal breathing, feeling of pressure, and headache were used. The presence of synechiae, infection, or granulation was noted and recorded with the video-endoscopy. Results A significant difference according to lower pressure was found in the NasoPore group compared to the controls on day ten after surgery. The NasoPore packing had lower scores with respect to postoperative nose blockage on the 2nd and 10th days. Mucosal healing was better for the NasoPore group, both at day ten and 30 compared with the control group. Conclusion The overall patient comfort is higher when using NasoPore compared to non-resorbable traditional impregnated gauze packing. Intensive saline douches applied three to four times per day are mandatory after the operation to prevent synechiae formation and fluid resorption by the packing.


Resumo Introdução O tamponamento nasal após cirurgia sinusal endoscópica é procedimento de rotina. A solução ideal para minimizar ou eliminar as desvantagens desse procedimento pode ser alcançada com o uso de tampões biodegradáveis. Objetivo Comparar a satisfação do paciente e o desfecho clínico associados ao uso de tampões absorvíveis e não absorvíveis após a cirurgia funcional dos seios paranasais (FESS- Functional Endoscopic Sinus Surgery). Método Foram incluídos 50 pacientes neste estudo prospectivo, duplo-cego e randomizado. Um dos lados foi tamponado com espuma de poliuretano, enquanto no outro lado foi feito um tamponamento com gaze. Nos 2º, 10º e 30º dias após a operação, os pacientes foram perguntados com a ajuda de uma escala analógica visual. Foram empregados questionários padronizados para sangramento, respiração nasal, sensação de pressão e cefaleia. A presença de sinequias, infecção ou granulação foi registrada por videoendoscopia. Resultados Foi observada diferença significante, da sensação de pressão, menor no lado tratado com NasoPore vs. controles no 10º dia após a cirurgia. O tamponamento com NasoPore obteve escores mais baixos com respeito ao bloqueio nasal pós-operatório no 2º e 10º dias. A cicatrização da mucosa foi melhor no lado do NasoPore, mas no 10º e 30º dias os resultados foram comparáveis com os do lado de controle. Conclusão O conforto geral do paciente é maior com o uso de NasoPore vs. tamponamento tradicional com gaze besuntada não reabsorvível. O uso vigoroso de jatos de solução salina aplicados 3-4 vezes ao dia é um procedimento obrigatório após a cirurgia, para evitar a formação de sinequias e para uma absorção natural do tampão.

ABSTRACT

Introducción: la cirugía de amígdalas y adenoides es la más frecuentemente realizada en otorrinolaringología. La incidencia de complicaciones es baja, siendo la hemorragia la más frecuente y seria. Se estima que la incidencia de hemorragia post adenoamigdalectomia es entre 0,1 y 8,1%. Dentro de las técnicas hemostáticas se utilizan suturas, electrocauterio, radiofrecuencia, presión con packs, vasoconstrictores u otras sustancias hemostáticas. Entre estas últimas el subgalato de bismuto (activa el factor XII de la coagulación) ha sido empleado durante décadas para hemostasia de diferentes sitios quirúrgicos. El objetivo de este trabajo es determinar la eficacia de la pasta de subgalato de bismuto en la disminución de hemorragias post adenoamigdalectomías. Material y método: Trabajo retrospectivo con pacientes adultos y pediátricos intervenidos quirúrgicamente de amigdalectomía/ adenoidectomía mediante técnica de Daniels y cureta de Beckmann, a los que se dividió en dos grupos: Uno, sin la utilización de subgalato de bismuto y otro utilizando la pasta hemostática intraoperatoria. Posteriormente se comparó la incidencia de hemorragia postquirúrgica entre ambos grupos. Resultados: El primer grupo incluyó a 2.125 pacientes operados y el porcentaje de hemorragias post quirúrgicas sin la utilización del subgalato de bismuto fue de 4,56% (N=97). El otro grupo se conformó con 1.647 pacientes a los que se les aplicó la pasta de subgalato de bismuto en el lecho sangrante y el porcentaje de hemorragias post quirúrgicas descendió a 1,33% (N=22). La diferencia entre ambos grupos fue estadísticamente significativa p=0,001. Conclusiones: La pasta de subgalato de bismuto disminuye la incidencia de hemorragia post amigdalectomía.


Backgruond: tonsils and adenoid surgery are the most frequently performed in otorhinolaryngology. The incidence of complications is low, being the hemorrhage the most frequent and serious one (estimated between 0.1% and 8.1%). The hemostatic techniques used during surgery are sutures, electrocautery, radio frequency, pressure with packs, vasoconstrictors and other haemostatic substances. Between these last substances, Bismuth Subgalate (activates factor XII of coagulation) has been used during decades for hemostasis in different surgical sites. The objective is to determine the efficacy of Bismuth Subgalate paste in the reduction of postadenotonsillectomy hemorrhage. Material and method: Retrospective study including adult and pediatric patients who underwent tonsilectomy / adenoidectomy using the Daniels technique and Beckmann’s curette, which were divided into two groups: one without the use of bismuth subgalate and another using the intraoperative hemostatic paste. Subsequently, the incidence of postoperative hemorrhage between the two groups was compared. Results: The first group included 2,125 patients operated. The percentage of postoperative hemorrhages without the use of the bismuth subgalate was 4.56% (N = 97). The other group consisted of 1,647 patients in whom the Bismuth Subgalate paste was used as a hemostatic agent during surgery. The percentage of postoperative hemorrhage fell to 1.33% (N = 22). The difference between both groups was statistically significant p = 0.001. Conclutions: Bismuth subgalate paste decreases the incidence of post adenotonsillectomy hemorrhage.

ABSTRACT

Abstract Introduction: The main reason for nasal tampon placement after septoplasty is to prevent postoperative hemorrhage, while the secondary purpose is internal stabilization after operations involving the cartilaginous-bony skeleton of the nose. Silicone intranasal splints are as successful as other materials in controlling postoperative hemorrhages of septal origin. The possibility of leaving the splints intranasally for extended periods helps stabilize the septum in the midline. However, there is nothing in the literature about how long these splints can be retained inside the nasal cavity without increasing the risk of infection, postoperative complications, and patient discomfort. Objective: The current study aimed to evaluate the association between the duration of intranasal splinting and bacterial colonization, postoperative complications, and patient discomfort. Methods: Patients who had undergone septoplasty were divided into three groups according to the day of removal of the silicone splints. The splints were removed on the fifth, seventh, and tenth postoperative days. The removed splints were microbiologically cultured. Early and late complications were assessed, including local and systemic infections, tissue necrosis, granuloma formation, mucosal crusting, synechia, and septal perforation. Postoperative patient discomfort was evaluated by scoring the levels of pain and nasal obstruction. Results: No significant difference was found in the rate of bacterial colonization among the different groups. Decreased mucosal crusting and synechia were detected with longer usage intervals of intranasal silicone splints. Postoperative pain and nasal obstruction were also diminished by the third postoperative day. Conclusions: Silicone splints were well tolerated by the patients and any negative effects on postoperative patient comfort were limited. In fact, prolonged splint usage intervals reduced late complications. Long-term silicone nasal splint usage is a reliable, effective, and comfortable method in patients with excessive mucosal damage and in whom long-term stabilization of the bony and cartilaginous septum is essential.


Resumo Introdução: A principal razão para a colocação de tampões nasais em septoplastias é a prevenção de hemorragia pós-operatória, enquanto o objetivo secundário é a estabilização interna após cirurgias que envolvam o esqueleto cartilaginoso do nariz. Os splints intranasais de silicone são tão eficazes como outros materiais para o controle de hemorragias do septo no pós-operatório. A possibilidade de manter os splints intranasais por longos períodos ajuda a estabilizar o septo na linha média. No entanto, não há nada na literatura sobre quanto tempo esses splints podem ser mantidos na cavidade nasal sem aumentar o risco de infecção, complicações no pós-operatório e causar desconforto ao paciente. Objetivos: O presente estudo teve como objetivo avaliar a associação entre o tempo de tamponamento com splints intranasais e colonização bacteriana, complicações no pós-operatório e desconforto do paciente. Método: Os pacientes submetidos a septoplastia foram divididos em três grupos, de acordo com o dia da remoção dos splints de silicone. Os splints foram removidos no 5°, 7° e 10° dias de pós-operatório, e a seguir, cultivados microbiologicamente. Complicações precoces e tardias foram avaliadas, incluindo infecções locais e sistêmicas, necrose do tecido, formação de granulomas, crostas na mucosa, sinéquias e perfuração do septo. O desconforto do paciente no pós-operatório foi avaliado com o uso de pontuação dos níveis de dor e de obstrução nasal. Resultados: Nenhuma diferença significante foi encontrada na taxa de colonização bacteriana entre os diferentes grupos. Diminuições da formação de crostas na mucosa e de sinéquias foram detectadas com tempos mais longos de uso de splints de silicone. A dor e a obstrução nasal também diminuíram no terceiro dia de pós-operatório. Conclusões: O uso de splints de silicone foi bem tolerado pelos pacientes, e seus efeitos negativos sobre o conforto do paciente no pós-operatório foram limitados. De fato, o tempo prolongado de uso teve um efeito redutor sobre as complicações tardias. O uso prolongado de splint nasal de silicone é um método confiável, eficaz e pouco desconfortável em pacientes com lesão excessiva da mucosa e naqueles cuja estabilização óssea e cartilaginosa do septo a longo prazo é essencial.

ABSTRACT

ABSTRACT INTRODUCTION: Nasal packing is routinely used in septal surgery to prevent postoperative bleeding. OBJECTIVE: To demonstrate the possibility of transeptal suture as a safe and effective way to avoid nasal packing and to improve efficiency. METHODS: This is a prospective, descriptive, inferential cost study comprising 92 patients. Two randomized groups of patients were analyzed, one with nasal packing and the other with transeptal suture. RESULTS: In the group of transeptal suture no patient experienced postoperative bleeding, and a statistically significant reduction of pain and headache was demonstrated. At the same time, we improved efficiency by saving on material costs. CONCLUSIONS: Transeptal suture is an effective and safe alternative to classic nasal packing in septal surgery. Moreover, it improves the efficiency of the intervention by saving costs.


Resumo Introdução: O tamponamento nasal é usado rotineiramente na cirurgia septal para evitar sangramentos no pós-operatório. Objetivo: Demonstrar a possibilidade de se realizar uma sutura transeptal como alternativa eficaz e segura ao tamponamento nasal, com melhora na eficiência da intervenção. Método: Este é um estudo prospectivo, descritivo e de custo inferencial, compreendendo 92 pacientes. Dois grupos aleatórios foram estudados: um com tamponamento nasal e o outro com sutura transeptal. Resultado: No grupo de sutura transeptal, nenhum paciente experimentou sangramento no pós-operatório, tendo sido estatisticamente demonstrada uma significante redução de cefaléia e dor. Ao mesmo tempo, houve melhora na eficiência da intervenção, com economia no custo de material. Conclusões: A sutura transeptal é uma alternativa eficaz e segura ao tamponamento nasal clássico. Além do mais, melhora a eficiência da intervenção, economizando no custo de material.

ABSTRACT

ABSTRACT BACKGROUND AND OBJECTIVES: The use of tranexamic acid in primary total knee replacement surgeries has been the subject of constant study. The strategies to reduce bleeding are aimed at reducing the need for blood transfusion due to the risks involved. In this study we evaluated the use of tranexamic acid in reducing bleeding, need for blood transfusion, and prevalence of postoperative deep vein thrombosis in primary total knee replacement. METHOD: 62 patients undergoing primary total knee replacement were enrolled in the study, from June 2012 to May 2013, and randomized to receive a single dose of 2.5 g of intravenous tranexamic acid (Group TA) or saline (Group GP), 5 min before opening the pneumatic tourniquet, respectively. Hemoglobin, hematocrit, and blood loss were recorded 24 h after surgery. Deep vein thrombosis was investigated during patient's hospitalization and 15 and 30 days after surgery in review visits. RESULTS: There was no demographic difference between groups. Group TA had 13.89% decreased hematocrit (p = 0.925) compared to placebo. Group TA had a decrease of 12.28% (p = 0.898) in hemoglobin compared to Group GP. Group TA had a mean decrease of 187.35 mL in blood loss (25.32%) compared to group GP (p = 0.027). The number of blood transfusions was higher in Group GP (p = 0.078). Thromboembolic events were not seen in this study. CONCLUSION: Tranexamic acid reduced postoperative bleeding without promoting thromboembolic events.


RESUMO JUSTIFICATIVA E OBJETIVOS: O uso do ácido tranexâmico, em cirurgias de artroplastia total primária de joelho, tem sido objeto de constante estudo. As estratégias para redução de sangramento visam à redução da necessidade de transfusão de sangue devido aos riscos que apresentam. Neste estudo, propomos a avaliação do uso do ácido tranexâmico na redução do sangramento, na necessidade de transfusão de sangue e na prevalência de trombose venosa profunda (TVP) pós-operatória em artroplastia total primária de joelho. MÉTODO: Foram estudados 62 pacientes submetidos à artroplastia primária total de joelho, de junho de 2012 a maio de 2013, randomizados para receber ácido tranexâmico 2,5 g endovenoso (grupo AT), em dose única, ou soro fisiológico (grupo GP), cinco minutos antes da abertura do torniquete pneumático, respectivamente. Foram feitas dosagens de hemoglobina e hematócrito e medida a perda sanguínea 24 horas após a cirurgia. A TVP foi pesquisada durante a internação do paciente, 15 e 30 dias após a cirurgia nas consultas de revisão. RESULTADOS: Não houve diferenças demográficas entre os grupos estudados. O grupo GT apresentou queda do hematócrito 13,89% (p = 0,925) comparado com o grupo placebo. O grupo GT apresentou diminuição de 12,28% (p = 0,898) da hemoglobina comparado com o grupo GP. O grupo GT apresentou uma diminuição média de 187,35 ml nas perdas sanguíneas (25,32%) quando comparado com o grupo GP (p = 0,027). O número de transfusões sanguíneas foi maior no grupo GP (p = 0,078). Eventos tromboembólicos não foram evidenciados neste estudo. CONCLUSÕES: O ácido tranexâmico diminuiu o sangramento pós-operatório sem promover eventos tromboembólicos.

ABSTRACT

BACKGROUND AND OBJECTIVES: Postoperative bleeding has a great clinical importance and can contribute to increased mortality and morbidity in patients undergoing coronary artery bypass graft surgery. In this prospective, randomized, double-blind study, we evaluated the effect of prophylactic administration of fibrinogen concentrate on post-coronary artery bypass graft surgery bleeding. METHODS: A total of 60 patients undergoing coronary artery bypass surgery were randomly divided into two groups. Patients in the fibrinogen group received 1 g of fibrinogen concentrate 30 min prior to the operation, while patients in the control group received placebo. Post-operative bleeding volumes, prothrombin time, partial thromboplastin time, INR, hemoglobin and transfused blood products in both groups were recorded. A strict red blood cell transfusion protocol was used in all patients. RESULTS: There were no significant differences between intra-operative packed red blood cells infusion in the studied groups (1.0 ± 1.4 in fibrinogen group, and 1.3 ± 1.1 in control group). Less postoperative bleeding was observed in the fibrinogen group (477 ± 143 versus 703 ± 179, p = 0.0001). Fifteen patients in the fibrinogen group and 21 in the control group required post-op packed red blood cells infusion (p = 0.094). No thrombotic event was observed through 72 h after surgery. CONCLUSION: Prophylactic fibrinogen reduces post-operative bleeding in patients undergoing coronary artery bypass graft. .


JUSTIFICATIVA E OBJETIVO: a hemorragia no período pós-operatório é de grande importância clínica e pode contribuir para o aumento da morbidade e mortalidade em pacientes submetidos à cirurgia de revascularização coronária. Nesse estudo prospectivo, randômico e duplo-cego, avaliamos o efeito da administração profilática de concentrado de fibrinogênio sobre o sangramento após cirurgia de revascularização coronária. MÉTODOS: no total, 60 pacientes submetidos à cirurgia de revascularização coronária foram randomicamente divididos em dois grupos. Os pacientes do grupo fibrinogênio receberam 1 g de concentrado de fibrinogênio 30 minutos antes da operação, enquanto os doentes do grupo controle receberam placebo. Os volumes de sangramento no pós-operatório, tempo de protrombina, tempo de tromboplastina parcial, INR, hemoglobina e hemoderivados transfundidos em ambos os grupos foram registrados. Um protocolo de conduta rigoroso para transfusão de hemácias foi usado em todos os pacientes. RESULTADOS: não houve diferenças significantes entre as infusões de concentrados de hemácias nos grupos estudados (1,0 ± 1,4 no grupo fibrinogênio e 1,3 ± 1,1 no grupo controle). O grupo fibrinogênio apresentou menos sangramento no pós-operatório (477 ± 143 versus 703 ± 179, p = 0,0001). Quinze pacientes do grupo fibrinogênio e 21 do grupo controle precisaram de infusão de concentrado de hemácias no pós-operatório (p = 0,094). Evento trombótico não foi observado durante 72 h após a cirurgia. CONCLUSÃO: profilaxia com fibrinogênio reduz o sangramento no período pós-operatório de pacientes submetidos à revascularização coronária. .

En este estudio prospectivo, aleatorizado y doble ciego, evaluamos el efecto de la administración profiláctica del concentrado de fibrinógeno sobre el sangrado después de la cirugía de revascularización del miocardio. MÉTODOS: en total, 60 pacientes sometidos a cirugía de revascularización del miocardio fueron aleatoriamente divididos en 2 grupos. Los pacientes del grupo fibrinógeno recibieron 1 g de concentrado de fibrinógeno 30 min antes de la operación, mientras que los del grupo control recibieron placebo. Los volúmenes de sangrado en el postoperatorio, tiempo de protrombina, tiempo de tromboplastina parcial, INR, hemoglobina y hemoderivados transfundidos en ambos grupos fueron registrados. En todo los pacientes se usó un protocolo de conducta riguroso para la transfusión de hematíes. RESULTADOS: no hubo diferencias significativas entre las infusiones de concentrados de hematíes en los grupos estudiados (1 ± 1,4 en el grupo fibrinógeno y 1,3 ± 1,1 en el grupo control). El grupo fibrinógeno presentó menos sangrado en el postoperatorio (477 ± 143 versus 703 ± 179, p = 0,0001). Quince pacientes del grupo fibrinógeno y 21 del grupo control necesitaron infusión de concentrado de hematíes en el postoperatorio (p = 0,094). Ningún evento trombótico fue observado durante 72 h después de la cirugía. CONCLUSIÓN: la profilaxis con fibrinógeno reduce el sangrado en el período postoperatorio de pacientes sometidos a revascularización del miocardio. .

ABSTRACT

To compare three different dosing schedules of tranexamic acid to achieve good hemostasis intraoperatively and in post-operative period. Randomized controlled trials. Anaesthesia department, Armed Forces Institute of Cardiology/ National Institute of Heart Diseases [June 2011 to Jan 2013] A total of 128 patients, due for coronary artery bypass grafting were included in this study after informed consent. The patients were randomly divided into four groups. Group A, being the control group, did not receive tranexamic acid during the operation, whereas the remaining three groups received tranexamic acid just after the reversal of heparin with protamine sulphate. Group B received low dose, group C received medium dose and group D received high dose of tranexamic acid both as bolus and followed by infusion. Six patients, 4 from group B and 2 from group D were dropped out due to incomplete data or some complication. The blood loss at 6 hours and 24 hours after surgery were noted along with amount and type of transfusions needed and clinical outcomes. The total cardio-pulmonary bypass time, aortic cross-clamp time and chest closure time were also noted. Haemoglobin levels, coagulation profile and activated clotting time were noted and compared pre and post operatively. All the 4 groups were comparable with respect to age, weight, gender and personal history. Average 1eeding in group A was similar to group B after six hours [p = 0.755] and 24 hours [p = 0.343] but significantly higher as compared to group C [p < 0.001] and group D [p <0.001]. Group B also had more blood in chest drain as compared to group C [p <0.001] and group D [p <0.001]. Group C and group D had almost similar amount of blood loss after 6 hours [p = 0.916] as well as after 24 hours [p = 0.834]. This study showed that tranexamic acid, when given at a loading dose of 20 mg/kg or greater and followed by a maintenance infusion of 15 mg/kg/hr or greater, significantly reduced the amount of blood loss, both intra-operatively and post- operatively, in patients undergoing on-pump coronary artery bypass grafting
