ABSTRACT

Objetivo: descrever a incidência de complicações em feridas operatórias de mastectomia e identificar fatores associados. Método: estudo retrospectivo desenvolvido em uma coorte hospitalar de 545 mulheres mastectomizadas por câncer de mama no ano 2018 em um centro de assistência de alta complexidade em oncologia da cidade do Rio de Janeiro, Brasil, após aprovação por Comitê de Ética em Pesquisa. Os dados foram coletados a partir dos prontuários, permitindo cálculos da taxa de incidência e da razão da taxa de incidência para cada complicação. Resultados: a complicação que apresentou maior taxa de incidência foi o sangramento (57,14/100 mastectomias-dia), tendo como fatores associados a raça/cor da pele não branca (Razão da Taxa de Incidência: 3,11) e a diabetes mellitus (Razão da Taxa de Incidência: 0,48). Conclusão: os fatores associados ao sangramento da ferida operatória apontam para a necessidade de novas práticas no cuidado ao pós-operatório de mulheres mastectomizadas.


Objective: to describe the incidence of complications in mastectomy surgical wounds and to identify associated factors. Method: this retrospective study was conducted in a hospital cohort of 545 women mastectomized for breast cancer in 2018 at a high-complexity cancer care center Rio de Janeiro City, Brazil, after approval by the research ethics committee. Data were collected from medical records, allowing incidence rate and incidence rate ratio to be calculated for each complication. Results: the complication with the highest incidence rate was bleeding (57.14/100 mastectomies-day), associated factors being non-white race/skin color (incidence rate ratio 3.11) and diabetes mellitus (incidence rate ratio 0.48). Conclusion: the factors associated with bleeding from the surgical wound point to the need for new practices in post-operative care for women with mastectomies.

ABSTRACT

ABSTRACT BACKGROUND: In July 2012, the Japan Gastroenterological Endoscopy Society updated their guidelines for gastroenterological endoscopy in patients receiving antithrombotic therapy. Colonoscopic polypectomy procedures are associated with a high risk of bleeding. OBJECTIVES: The present study evaluated the safety of colonoscopic polypectomy procedures in terms of bleeding, among patients receiving antithrombotic therapy. DESIGN AND SETTING: Prospective observational study conducted in a tertiary-level public cardiovascular hospital in Istanbul, Turkey. METHODS: Colonoscopic polypectomies carried out in a single endoscopy unit between July 2018 and July 2019 were evaluated prospectively. The patients' data, including age, gender, comorbidities, whether antithrombotic drug use was ceased or whether patients were switched to bridging therapy, polyp size, polyp type, polyp location, histopathology, resection methods (hot snare, cold snare or forceps) and complications relating to the procedures were recorded. RESULTS: The study was completed with 94 patients who underwent a total of 167 polypectomy procedures. As per the advice of the physicians who prescribed antithrombotic medications, 108 polypectomy procedures were performed on 60 patients without discontinuing medication and 59 polypectomy procedures were performed on 34 patients after discontinuing medication. The age, gender distribution and rate of bleeding did not differ significantly between the patients whose medication was discontinued and those whose medication was continued (P > 0.05). CONCLUSION: This study found that the colonoscopic polypectomy procedure without discontinuation of antithrombotic medication did not increase the risk of bleeding. This procedure can be safely performed by experienced endoscopists in patients with an international normalized ratio (INR) below 2.5.

ABSTRACT

OBJECTIVE@#To investigate the application of tranexamic acid in the treatment of intertrochanteric fracture.@*METHODS@#From January 2017 to October 2019, 100 patients with intertrochanteric fracture were randomly divided into observation group (48 cases) and control group(52 cases). All patients received the same surgical treatment. The control group was given tranexamic acid 20 minutes before operation, and 15 mg/kg diluted in 250 ml sodium chloride injection, intravenous drip;the observation group was given tranexamic acid 0.5 g dissolved in 20 ml normal saline injected into femoral bone marrow cavity for local treatment on the basis of the control group. The blood loss, operation time and postoperative hospital stay were compared between two groups. Hematocrit, hemoglobin, D-dimer and fibrinogen levels were analyzed before and after operation, and the incidence of thrombotic complications was observed.@*RESULTS@#The total blood loss, dominant blood loss, hidden blood loss and postoperative drainage volume of the observation group were significantly lower than those of the control group (@*CONCLUSION@#Tranexamic acid combined with systemic and local application has important clinical significance in reducing perioperative blood lossand blood cell loss in patients with intertrochanteric fracture, and has good safety.

ABSTRACT

Abstract Background: Bleeding as a complication is associated with poorer results in cardiac surgery. There is increasing evidence that the use of blood products is an independent factor of increased morbidity, mortality, and hospital costs. Dyke et al. established the universal definition of perioperative bleeding (UDPB). This classification is more precise defining mortality in relation to the degree of bleeding. Methods: A descriptive and analytical retrospective study of a database of patients underwent cardiac surgery from January 1, 2016, to December 31, 2017, was performed. The primary objective of the study was to look at mortality associated with the degree of bleeding using the UDPB. Results: A total of 918 patients who went to cardiac surgery were obtained. Most of the population was classified as insignificant bleeding class (n = 666, 72.9%), and for massive bleeding the lowest proportion (n = 25, 2.7%). For the primary outcome of 30-day mortality, a significant difference was found between the groups, observing that it increased to a higher degree of bleeding. This was corroborated by multivariate logistic regression analysis that was adjusted to EuroScore II and cardiopulmonary bypass (CPB) duration, finding an independent association of the bleeding class with 30-day mortality (OR, 95%, 5.82 [2.22-15.26], p = 0.0001). Conclusions: We found that the higher the degree in UDPB was associated with higher mortality independently to EuroScore II and CPB duration for adult patients undergoing cardiac surgery.


Resumen Antecedentes: El sangrado como complicación está asociado a peores resultados en cirugía cardiaca. Existe una evidencia cada vez mayor que la transfusión de productos sanguíneos por si solo es un factor independiente de incremento en la morbilidad, mortalidad, y costos hospitalarios. Dyke y colaboradores establecieron la definición universal de sangrado perioperatorio. Esta clasificación es más precisa en definir mortalidad en relación con el grado de sangrado. Material y métodos: Se realizo un estudio descriptivo y analítico de tipo retrospectivo de una base de datos de pacientes que fueron a cirugía cardiaca del 1 enero del 2016 al 31 de diciembre del 2017. El objetivo primario del estudio fue observar la mortalidad asociada con el grado de sangrado utilizando la definición universal de sangrado perioperatorio. Resultados: Se obtuvieron un total de 918 pacientes que fueron a cirugía cardiaca. La mayor parte de la población fue clasificada como clase de sangrado insignificante (n = 666, 72.9%), y para sangrado masivo la menor proporción (n = 25, 2.7%). En el desenlace primario de mortalidad a 30 días se encontró una diferencia significativa entre los grupos, observando que aumentada a mayor clase de sangrado. Esto fue corroborado mediante un análisis multivariado regresión logística que fue ajustado a con EuroScore II y el tiempo de bomba de circulación extracorpórea, encontrando una asociación independiente de la clase de sangrado con mortalidad a 30 días (OR, 95%, 5.82 [2.22-15.26], p = 0.0001). Conclusiones: Encontramos que cuanto mayor era el grado en la UDPB se asociaba con una mayor mortalidad independientemente de EuroScore II y la duración del bypass cardiopulmonar para pacientes adultos sometidos a cirugía cardíaca.

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 Tonsillectomy is one of the most common surgeries in the head and neck worldwide. This operation is carried out by different methods, the most frequent of which are the cold dissection and bipolar electrocautery techniques. Objective This study was conducted to assess and compare postoperative morbidity between cold dissection and bipolar electrocautery. Methods This prospective randomized clinical trial was performed on 534 patients who underwent tonsillectomy in Vali-e-Asr Hospital of Birjand, east of Iran from October, 2013 to October, 2015. The patients were systematically selected for cold dissection technique or bipolar electrocautery technique groups. Time of surgery, amount of intraoperative blood loss, postoperative hemorrhage, the intensity of local pain 4 and 24 hours after operation and nausea and/or vomiting were recorded and compared in the two groups to decide which technique is better. The data were analyzed in SPSS software (ver-22). The p-value less than 0.5 was considered significant. Results In this study, 51.7% of the cold dissection technique patients and 50.6% of the bipolar electrocautery technique participants were male. Compared to the cold dissection technique, the average intraoperative blood loss was significantly lower (p < 0.001) in the bipolar electrocautery technique group, while the intensity of local pain 4 and 24 hours after the operation was significantly higher (p < 0.001). Other variables showed no significant differences between the two groups. Conclusion Based on the findings of the present investigation, the bipolar electrocautery technique is suggested for tonsillectomy in children, while the cold dissection technique is preferred for adult patients.


Resumo Introdução A tonsilectomia é uma das cirurgias mais comuns de cabeça e pescoço em todo o mundo. Essa cirurgia é feita por diferentes métodos, os mais frequentes são a dissecção a frio e por eletrocauterização bipolar. Objetivo Este estudo foi feito para avaliar e comparar a morbidade pós-operatória na dissecção a frio e eletrocauterização bipolar. Método Este ensaio clínico prospectivo e randomizado foi feito em 534 pacientes submetidos a tonsilectomia no Vali-e-Asr Hospital de Birjand, no leste do Irã, de outubro de 2013 a outubro de 2015. Os pacientes foram selecionados de forma sistemática para o grupo submetido à técnica de dissecção a frio ou para o grupo com uso da técnica de eletrocauterização bipolar. Para a avaliação acerca da melhor técnica, os seguintes parâmetros foram registrados e comparados entre os dois grupos: tempo de cirurgia, quantidade de perda sanguínea intraoperatória, hemorragia pós-operatória, intensidade da dor local 4 e 24 horas após a cirurgia e ocorrência de náuseas e/ou vômitos. Os dados foram analisados no software SPSS (versão 22). O valor de p inferior a 0,5 foi considerado significante. Resultados Neste estudo, 51,7% dos participantes do grupo técnica de dissecção a frio e 50,6% do grupo técnica de eletrocauterização bipolar eram do sexo masculino. No grupo operado pela técnica de eletrocauterização bipolar a média de perda sanguínea intraoperatória foi significantemente menor (p < 0,001) em comparação à técnica de dissecção a frio, enquanto a intensidade da dor local 4 e 24 horas após a cirurgia foi significativamente maior (p < 0,001). As outras variáveis não apresentaram diferenças significantes entre os dois grupos. Conclusão Com base nos achados da presente investigação, para a tonsilectomia em crianças sugere-se o uso da técnica de eletrocauterização bipolar, enquanto a técnica de dissecção a frio é recomendada para pacientes adultos.

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

OBJETIVO: El objetivo principal de este estudio fue determinar la incidencia de complicaciones post cirugía bucal. METODOLOGÍA: Se desarrolló un estudio observacional, descriptivo, con el uso del registro prospectivo de la totalidad de pacientes ingresados para cirugía bucal del Complejo Hospitalario San Borja-Arriarán durante doce meses de observación (abril 2017 a marzo 2018). RESULTADOS: La muestra estuvo conformada por 532 pacientes sometidos a procedimientos quirúrgicos de cirugía bucal y 29 casos de complicación postquirúrgica. La incidencia de complicaciones alcanzó un 5,5% y se observó de manera predominante en intervenciones de tipo exodoncia. La complicación mayormente observada fue la alveolitis alcanzando un 2,5% de las cirugías de terceros molares y un 3,7% de las exodoncias de otros dientes. Las hemorragias postoperatorias se observaron en un 1,1% de las cirugías de terceros molares. Otras complicaciones postquirúrgicas fueron abscesos de espacios faciales, parestesia del nervio alveolar inferior, hematomas, equimosis y periostitis. CONCLUSIÓN: Los resultados fueron similares a los reportados en la literatura tanto en su frecuencia como en el tipo de complicación.


OBJECTIVE: The main objective of this investigation was to determine the incidence of postoperative complications in oral surgery. MATERIALS AND METHODS: An observational and descriptive study was developed with the use of the prospective registry of the patients admitted for oral surgery in the San Borja Arriarán Hospital Complex for a twelve-month period of observation (April 2017 to March 2018). RESULTS: The sample consisted of 532 patients undergoing surgical procedures of oral surgery and 29 cases of postoperative complications. The incidence of complications reached 5,5% and it was observed predominantly in interventions of tooth extraction. The most commonly observed complication was dry socket, reaching 2,5% of third molar surgeries and 3,7% of extractions of other teeth. Postoperative hemorrhages were observed in 1,1% of third molar surgeries. Other postoperative complications were facial spaces abscesses, paresthesia of the inferior alveolar nerve, bruising, ecchymosis and periostitis. CONCLUSIONS: The results were similar to those reported in the literature both in their frequency and in the type of complication.

Objetivos: Estimar la incidencia de complicaciones intraquirúrgicas (CI) y posquirúrgicas (CP) en los procedimientos de cirugía dermatológica y caracterizarlas en el ámbito de una sala de procedimientos de un hospital de referencia de la Ciudad Autónoma de Buenos Aires. Diseño: Trabajo de investigación descriptivo, prospectivo, observacional y longitudinal. Materiales y métodos: Se recolectó información demográfica del paciente y operativa en el momento del procedimiento quirúrgico. Se clasificaron las complicaciones quirúrgicas que se presentaron hasta un mes posterior al procedimiento en los pacientes intervenidos en la sección de Dermatología Quirúrgica del Hospital F. J. Muñiz, en el período comprendido entre febrero de 2015 y marzo de 2018. Resultados: Se halló una incidencia de 0% (IC 95%: 0 a 0,4) para las CI y de 4,4% (IC 95%: 3,2 a 5,9) para las CP en una serie de 765 pacientes (937 procedimientos). La CP más frecuente fue dehiscencia (68%), seguida de infección (16%), variantes de sangrado (9%) y necrosis (7%). Ninguna fue grave ni incluyó muerte, hospitalización o secuelas permanentes. Conclusiones: La dermatología quirúrgica en el ámbito de una sala de procedimientos es segura y el porcentaje de complicaciones es bajo comparable con lo publicado en la bibliografía internacional. (AU)


Background: Although the global complications in surgical dermatology referred to in the worldwide literature are low (1.64- 4.58%), regional publications with prospective data on them are scarce and nationally non-existent. Objectives: Estimate the incidence of intra-surgical complications (IC) and post-surgical complications (PC) in dermatological surgery procedures and characterize them within the scope of a reference hospital in the Autonomous City of Buenos Aires. Design: Descriptive, prospective, observational and longitudinal research work. Materials and methods: Demographic information of the patient and operative data were collected at the time of the surgical procedure. Surgical complications that occurred up to one month after the procedure on patients undergoing surgery in the surgical dermatology section of the F. J. Muñiz Hospital between February 2015 to March 2018 were classified. Results: The incidence found was 0% (95% CI 0-0.4) for IC and 4.4% (95% CI 3.2-5.9) for PC in a series of 765 patients (937 procedures). The most frequent PC was dehiscence (68%), followed by infection (16%), bleeding variants (9%) and necrosis (7%). Neither the PC were severe, not included death, hospitalization or permanent sequelae. Conclusions: Office based dermatologic surgery is safe and the percentage of complications is low, comparable to that published in the international literature. (AU)

ABSTRACT

OBJECTIVE@#To investigate the effect of intra-articular injection of tranexamic acid on blood loss and blood transfusion rate after minimally invasive unicompartmental knee arthroplasty.@*METHODS@#From January 2015 to September 2017, 90 patients underwent minimally invasive unicompartmental knee arthroplasty were divided into tranexamic acid group and control group, 45 cases in each group. In the tranexamic acid group, there were 22 males and 23 females, aged 62 to 69 (66.1±2.4) years;in the control group, 20 males and 25 females, aged 63 to 71(68.5±5.2) years. The amount of bleeding in the drainage ball at 48 hours after operation was recorded, and the blood transfusion rate and hematocrit level duringthe perioperative period were recorded. The factors influencing perioperative blood loss included gender, age and body mass index (BMI).@*RESULTS@#All patients were followed up for 12.5 to 28.3 (22.8±7.9) months. During the follow-up, the wounds of the two groups healed well, and no deep vein thrombosis and pulmonary embolism occurred. There was no significant difference in postoperative blood loss between the tranexamic acid group and the control group. The postoperative bleeding volume in the tranexamic acid group was (110.0±52.1) ml, and that in the control group was (123.0±64.5) ml (P=0.39). There was no blood transfusion in the two groups.@*CONCLUSION@#Intra articular injection of tranexamic acid can not significantly reduce the postoperative blood loss in patients with minimally invasive unicompartment.

ABSTRACT

Resumen: Introducción: La reducción de la pérdida sanguínea y de las transfusiones en pacientes operados de artroplastía total de rodilla (ATR) primaria se asocia a un mejor resultado clínico y funcional. El uso de ácido tranexámico (ATX) es uno de los métodos utilizados para disminuir ese sangrado. Material y métodos: Se compararon los resultados en hemoglobina (Hb), hematocrito (Hto), tasa de sangrado y de transfusión, tiempo quirúrgico y dolor entre los grupos A (con ATX) y grupo B (sin ATX) posterior a la ATR. Resultados: Se encontraron diferencias estadísticamente significativas en la disminución del sangrado transquirúrgico y periquirúrgico global, en la disminución de la Hb a las 24 horas, en la tasa de transfusión, en el tiempo quirúrgico y en el dolor a la deambulación a favor del grupo A. Discusión: En México no hay literatura publicada sobre el uso de ATX en pacientes operados de ATR. A pesar del uso cada vez más común del ATX, la mejor dosis y vía de administración sigue siendo un tema controversial. Conclusión: El uso de ATX en el esquema propuesto es un método seguro y eficaz para disminuir la tasa de sangrado y de transfusiones en los pacientes operados de ATR.


Abstract: Background: Reducing blood loss and transfusions in patients operated on primary TKR is associated with a better clinical and functional outcome. The use of Tranexamic Acid (ATX) is one of the methods used to decrease that bleeding. Material and methods: Results in Hb, Hto, rate of bleeding and transfusion, surgical time and pain between groups A (with ATX) and group B (without tranexamic acid) after TKR are compared. Results: Statistically significant differences were found during surgery and perisurgical bleeding, in the decrease of Hb at 24 hours, transfusion rate, surgical time and pain to wandering in favor of group A. Discussion: There are no published studies in Mexico on the use of ATX in patients operated on TKR. We consider its use to be increasingly common, the optimal dose and route of administration remains a controversial topic. Conclusion: The use of ATX in the proposed scheme is safe and effective in reducing the rate of bleeding and transfusions in patients operated on ATR.

ABSTRACT

Abstract Objective: To examine the effects of classical technique, electrocautery, and ultrasonic dissection on endothelial integrity, function, and preparation time for harvesting the radial artery (RA) during coronary artery bypass grafting (CABG). Methods: Forty-five patients who underwent isolated CABG and whose RA was suitable for use were studied and divided into three groups: Group 1, classical method (using sharp dissection); Group 2, electrocautery; and Group 3, ultrasonic cautery. Levels of prostacyclin and nitric oxide derivatives were examined biochemically; vascular cell adhesion molecule 1 (VCAM-1) and endothelial nitric oxide synthetase (eNOS) values were assessed using immunohistochemical staining. RA preparation time, RA length/harvesting time ratio, and drainage amounts at the site of RA removal were compared. Results: Differences in RA preparation time (Group 1: 25±6 min, Group 2: 18±3 min, Group 3: 16±3 min, P<0.001) and length/harvesting time ratio (Group 1: 0.76±0.19 cm/min, Group 2: 0.98±0.16 cm/min, Group 3: 1.13±0.09 cm/min, P<0.001) were statistically significant among the groups. Levels of prostacyclin and nitric oxide derivatives were not statistically significant different, VCAM-1 and eNOS expressions were observed to be similar among the groups, and endothelial damage was detected in only one patient per group. Conclusion: Use of ultrasonic cautery during RA preparation considerably reduces the preparation time and postoperative drainage amount. However, the superiority of one method over the others could not be demonstrated when the presence of endothelial damage with both biochemical and histopathological evaluations was considered.

ABSTRACT

Introduction: Tonsillectomy is one of the most common otolaryngology procedures performed worldwide. It is also one of the first procedures learnt by residents during their training period. Although tonsillectomy is viewed relatively as a low-risk procedure, it can be potentially harmful because of the chance of posttonsillectomy hemorrhage. Objective: The objective of the present study is to analyze the effects of peroperative factors and experience of the surgeon on the incidence and pattern of posttonsillectomy reactionary hemorrhage. Methods: A retrospective review of medical charts was performed from 2014 to 2017 in a tertiary care hospital. A total of 1,284 patients who underwent tonsillectomy and adenoidectomy were included in the study. The parameters assessed were experience of the surgeon, operating time, intraoperative blood loss, difference in mean arterial pressure (MAP) and pulse rate. Results: A total of 23 (1.79%) out of the 1,284 patients had reactionary hemorrhage. Out of those 23, 16 (69.5%) patients had been operated on by trainees, while 7 (30.5%) had been operated on by consultants (p = 0.033, odds ratio [OR] = 0.04). Operating time, intraoperative blood loss, difference in MAP and pulse rate were significantly higher in the reactionary hemorrhage group, and showed a positive association with risk of hemorrhage (p < 0.05; OR >1). Re-exploration to control the bleeding was required in 10 (76.9%) out of the 23 cases. Conclusion: The experience of the surgeon experience and peroperative factors have an association with posttonsillectomy hemorrhage. Close surveillance and monitoring of the aforementioned peroperative factors will help in the identification of patients at risk of hemorrhage (AU)

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 investigate whether low bleeding influences the early outcomes after off-pump coronary artery bypass grafting (CABG). Methods: Retrospective analysis of ischemic heart disease patients who underwent off-pump CABG from January 2013 to December 2017. Patients were divided into low-bleeding group (n=659) and bleeding group (n=270), according to total drainage from chest tube during the first postoperative 12 hours. Clinical material and early outcomes were compared between the groups. Results: Baseline was similar in the two groups. Operation time was 270±51 min in the low-bleeding group and 235±46 min in the bleeding group (P<0.0001). The low-bleeding group presented smaller drainage during the first 12 h (237±47 ml) and shorter mechanical ventilation time (6.86±3.78 h) than the bleeding group (557±169 ml and 10.66±5.19 h, respectively) (P<0.0001). Hemodynamic status was more stable in the low-bleeding group (P<0.0001) and usage rate of more than two vasoactive agents in this group was lower than in the bleeding group (P<0.0001). Number of distal anastomosis, reoperation for bleeding, suddenly increase in chest tube output, intensive care unit (ICU) stay, hospital stay, and other early outcomes had no statistical significance between the groups (P>0.05). Conclusion: Postoperative bleeding < 300 ml/12 h in off-pump CABG patients did not require blood product transfusion and reoperation and that would contribute to reduction in mechanical ventilation time and maintaining hemodynamic stability. Bleeding < 800 ml during the first postoperative 12 h did not increase infection rates and ICU length of stay.

ABSTRACT

Abstract Angiomyolipomas (AMLs) are rare benign tumors derived from mesenchymal tissue and composed of varying degrees of adipose tissue, muscle and blood vessels. Renal AMLs (RAMLs) are the result of a sporadic event, and, in most of cases, the diagnosis is usually incidental, but hemorrhage and shock may be present. During pregnancy, the size of AMLs may increase and they may rupture, probably due to the high expression of hormone receptors, and the increase in maternal circulation and abdominal pressure. The authors present a case of a woman with ruptured RAML submitted to urgent endovascular treatment four days after giving birth by cesarean section.

ABSTRACT

RESUMO A artroplastia total do joelho é um procedimento eletivo, realizado em indivíduos relativamente saudáveis. Porém, devido ao risco inerente de tromboembolismo venoso, são utilizados fármacos para sua profilaxia. O objetivo do presente trabalho foi conduzir uma revisão sistemática da literatura para comparar a eficácia da enoxaparina e da rivaroxabana na prevenção desta complicação e no risco de sangramento intraoperatório. Foi feita uma revisão no site SciELO, Pubmed e Cochrane através dos descritores, artroplastia de joelho, rivaroxabana e enoxaparina através da estratégia de busca PICO. Os critérios de inclusão foram os artigos no período estudado, que comparavam ambas as drogas em cirurgias de artroplastia do joelho. Os critérios de relevância para tornar o estudo elegível foram definidos como: somente artigos publicados a partir 2010 e com casuística com mais de 20 pacientes foram considerados; somente estudos obtidos em sua íntegra foram analisados; somente estudos com seguimento maior do que 12 meses foram considerados relevantes. As variáveis utilizadas para a comparação dos artigos foram as complicações mais comuns no pós-operatório de artroplastias do joelho: tromboembolismo venoso e sangramento. Foi utilizado o Review Man 5.3 para estruturação da revisão. Os autores observaram que nos estudos analisados, considerando tromboembolismo venoso sintomático, a rivaroxabana resultou em maiores benefícios quando comparada com a enoxaparina.


ABSTRACT Total knee arthroplasty is an elective procedure performed on relatively healthy individuals. However, due to the inherent risk of venous thromboembolism, drugs are used for its prophylaxis. The objective of the present study was to conduct a systematic review of the literature to compare the efficacy of enoxaparin and rivaroxaban in preventing this complication and the risk of intraoperative bleeding. We reviewed the SciELO, Pubmed and Cochrane databases with the descriptors knee arthroplasty, rivaroxaban and enoxaparin through the PICO search strategy. Inclusion criteria were the articles during the study period comparing both drugs in knee arthroplasty. Relevant criteria to study eligibility were articles published since 2010 and with a sample of more than 20 patients; studies obtained in their entirety; and studies with follow-up of more than 12 months. The variables used to compare the articles were the most common postoperative complications of knee arthroplasties: venous thromboembolism and bleeding. We used the Review Man software, version 5.3, for structuring the review. In the studies analyzed, considering symptomatic venous thromboembolism, rivaroxaban resulted in higher benefits when compared to enoxaparin.
