Results of office-based fluid-air exchange for postvitrectomy hemorrhage in diabetic retinopathy

ABSTRACT Purpose: This study aimed to evaluate the efficacy and clinical outcomes of a one-way fluid-air exchange procedure for the treatment of postvitrectomy diabetic vitreous hemorrhage in patients with proliferative diabetic retinopathy. Methods: This retrospective study included 233 patients with proliferative diabetic retinopathy, who underwent vitrectomy. A one-way fluid-air exchange procedure was performed in 24 eyes of 24 (10.30%) patients with persistent vitreous cavity rebleeding after the operation. Preprocedural and postprocedural best-corrected visual acuity values were achieved. Complications occurring during and after the procedure were analyzed. Results: Significant visual improvement was observed 1 month after the one-way fluid-air exchange procedure (2.62 ± 0.60 LogMAR at baseline vs. 0.85 ± 0.94 LogMAR at postprocedure, p<0.0001). Moreover, 19 (79.17%) eyes needed the procedure once, and 5 (20.83%) eyed had the procedure more than twice. In 3 (12.50%) eyes, reoperation was eventually required because of persistent rebleeding despite several fluid-air exchanges. No complication was observed during the follow-up. Conclusions: The one-way fluid-air exchange procedure can be an excellent alternative to re-vitrectomy for patients with proliferative diabetic retinopathy suffering from postvitrectomy diabetic vitreous hemorrhage by removing the hemorrhagic contents directly and achieving fast recovery of visual function without apparent complications.

Efficacy of different compression methods for hemostasis at the radial artery puncture point after percutaneous coronary intervention / 中国基层医药

Objective:To compare the hemostatic effects and patient comfort of different compression methods for hemostasis after transradial coronary intervention.Methods:A total of 160 patients who received transradial coronary intervention in The Affiliated Hospital of Hangzhou Normal University from October 2018 to February 2020 were included in this study. In group A ( n = 80), patients underwent spiral compression at the puncture point (release for 1 turn at 2 hours after surgery, rotation for 1 circle after 1 hour, and full decompression). In group B ( n = 80), patients underwent spiral compression at the puncture point (release for 1 turn at 2 hours after surgery, rotation for 1 circle after 2 hours, and full decompression). Percutaneous arterial oxygen saturation value in the affected limb, heart rate, and Visual Analog Scale score at different times after surgery, pain and comfort score at 2 and 12 hours post-surgery were compared between the two groups. Results:Percutaneous arterial oxygen saturation value at 4 and 12 hours post-surgery in group A was (96.6 ± 0.7)% and (97.8 ± 0.5)%, respectively, which was significantly higher than that in group B [(96.2 ± 0.6)%, (97.6 ± 0.7)%, t = 3.88, 2.08, both P < 0.05]. There were no significant differences in total score and subscale score of the General Comfort Questionnaire at 2 hours post-surgery between groups A and B (both P < 0.05). At 12 hours post-surgery, scores of psychological and physical subscales and total score of the General Comfort Questionnaire in group A were (23.64 ± 3.02) points, (12.64 ± 2.05) points, (68.25 ± 6.04) points, which were significantly higher than those in group B [(22.20 ± 2.96) points, (11.38 ± 2.47) points, (64.42 ± 6.71) points, t = 3.05, 3.51, 3.79, all P < 0.05]. At 2 hours post-surgery, there was no significant difference in Numerical Rating Scale score between groups A and B ( P > 0.05). At 4 and 12 hours post-surgery, Numerical Rating Scale score in group A was (2.51 ± 0.58) points and (1.75 ± 0.76) points, respectively, which was significantly lower than that in group B [(2.95 ± 0.63) points, (2.31 ± 0.71) points, t = -4.59, -4.82, both P < 0.05). The incidence of complications was significantly lower in group A than in group B (8.75% vs. 20.00%, χ2 = 4.11, P < 0.05). Conclusion:Compression for hemostasis is highly effective by releasing for 1 turn at 2 hours after transradial coronary intervention, rotating for 1 circle after 1 hour, and full compression because it can greatly mitigate pain, ensure the oxygen supply to the affected limbs, and improve patient comfort.

Analysis of the efficacy and related influencing factors of pelvic packing in the treatment of intractable postpartum hemorrhage after emergency perinatal hysterectomy / 中华妇产科杂志

Objective:To investigate the effect of pelvic packing on the control of intractable postpartum hemorrhage after emergency perinatal hysterectomy (EPH).Methods:Eleven cases with complete clinical data of pelvic packing due to failure of hemostasis after EPH were collected to evaluate the outcome, complications, hospital stay of pregnant women, and to analyze the factors affecting the effect of pelvic packing. The cases included patients who were admitted to the Third Affiliated Hospital of Guangzhou Medical University after pelvic packing treatment in the other hospital due to continuous bleeding after EPH or who were referred to our hospital for pelvic packing treatment due to continuous bleeding after EPH from January 2014 to August 2021.Results:The median gestational week of 11 pregnant women was 38.3 weeks(38.0-39.9 weeks) , and the methods of termination of pregnancy were cesarean section in 7 cases (7/11) and vaginal delivery in 4 cases (4/11). The median time between postpartum hemorrhage and pelvic tamponade was 10 hours (5-57 hours), the median amount of bleeding was 8 500 ml(4 800-15 600 ml) , the median number of pelvic tamponade was 3 pieces (2-7 pieces), and the median retention time of gauze pad was 6.0 days (3.0-6.0 days). The median frequency of laparotomy in this pregnancy was 3 times (2-3 times), with a maximum of 4 among the 11 cases, the first pelvic packing was successful in hemostasis in 9 cases, and the final successful treatment in all of the 11 cases. All parturients had hemorrhagic shock (11/11) and disseminated intravascular coagulation (11/11) before pelvic packing. Other common complications were multiple organ dysfunction syndrome (9/11), cardiac arrest (4/11), deep vein thrombosis (3/11), septic shock (3/11), and intestinal obstruction (1/11). All parturients took out the gauze after the coagulation function returned to normal and there was no active bleeding. The recovery time of coagulation function in 11 cases was 3 days (3-5 days), the retention time of gauze pad was 6 days (3-6 days), the median length of stay in intensive care unit was 14 days (11-26 days), and the median total length of stay was 22 days (16-49 days).Conclusions:Pelvic packing could be used as a temporary strategy for intractable postpartum hemorrhage after EPH, which provides a key time for injury control resuscitation for patients with unstable vital signs. This technology provides an opportunity for referral to superior medical institutions and further treatment.

Prehospital Damage Control: The Management of Volume, Temperature… and Bleeding! / Control de Daños Prehospitalario: ¡Para Los Cristaloides, Para La Hipotermia Y…! ¡Para El Sangrado!

Abstract Damage control resuscitation should be initiated as soon as possible after a trauma event to avoid metabolic decompensation and high mortality rates. The aim of this article is to assess the position of the Trauma and Emergency Surgery Group (CTE) from Cali, Colombia regarding prehospital care, and to present our experience in the implementation of the "Stop the Bleed" initiative within Latin America. Prehospital care is phase 0 of damage control resuscitation. Prehospital damage control must follow the guidelines proposed by the "Stop the Bleed" initiative. We identified that prehospital personnel have a better perception of hemostatic techniques such as tourniquet use than the hospital providers. The use of tourniquets is recommended as a measure to control bleeding. Fluid management should be initiated using low volume crystalloids, ideally 250 cc boluses, maintaining the principle of permissive hypotension with a systolic blood pressure range between 80- and 90-mm Hg. Hypothermia must be management using warmed blankets or the administration of intravenous fluids warmed prior to infusion. However, these prehospital measures should not delay the transfer time of a patient from the scene to the hospital. To conclude, prehospital damage control measures are the first steps in the control of bleeding and the initiation of hemostatic resuscitation in the traumatically injured patient. Early interventions without increasing the transfer time to a hospital are the keys to increase survival rate of severe trauma patients.

Resumen La resucitación en el control de daños debe iniciarse lo más rápido posible después de presentado el evento traumático para evitar descompensación metabólica y aumento de la mortalidad. El objetivo de este artículo es sustentar nuestro enfoque respecto a la atención prehospitalaria y presentar nuestra experiencia en la implementación de la iniciativa "Stop the Bleed" en Latinoamérica. La atención prehospitalaria es la fase Cero de la resucitación del control de daños. Por medio de la implementación de la iniciativa "Stop the Bleed" se identificó que el personal prehospitalario tiene una mejor percepción sobre el uso de técnicas hemostáticas como el torniquete que el personal hospitalario. Se recomienda el uso de torniquetes como medida de control de sangrado en extremidades. El manejo de líquidos debe realizarse usando cristaloides a bajos volúmenes, con bolos de 250 mL para cumplir el principio de la hipotensión permisiva con un rango entre 80 y 90 mm Hg de presión arterial sistólica. Se deben realizar medidas para evitar la hipotermia como el uso de sábanas térmicas o paso de líquidos calientes. Estas medidas no deben retrasar en ningún momento el tiempo de traslado para recibir la atención hospitalaria. En conclusión, la atención prehospitalaria es el paso inicial para garantizar las primeras medidas de control de sangrado y de resucitación hemostática de los pacientes. Realizar intervenciones tempranas sin acortar el tiempo de traslado a la atención hospitalaria son las claves para aumentar la tasa de supervivencia.

Agentes hemostáticos tópicos em cirurgia: revisão e perspectivas / Topical hemostatic agents in surgery: review and prospects

RESUMO A hemostasia tem papel crítico e importância fundamental em todos os procedimentos cirúrgicos. Seu manejo possui diversos pontos chaves, que se iniciam por boa técnica operatória e adequado suporte anestésico. Determinadas situações, como hemorragias graves resultantes de trauma penetrante, por exemplo, não dependem exclusivamente do controle da equipe cirúrgica e necessitam do apoio de novas soluções que diminuam ou controlem a hemorragia. Desde os tempos antigos, um marco da medicina é atuar no controle da hemorragia e, mais recentemente, na facilitação da hemostasia pela aplicação de agentes tópicos, seja por compressão manual ou agentes modernos. Na última década, o número de diferentes agentes hemostáticos tópicos cresceu drasticamente. Para que o cirurgião moderno escolha o agente correto no momento correto, é essencial que conheça o mecanismo de ação, entenda a eficácia e os possíveis efeitos adversos relacionados a cada agente. Assim, a grande variedade de hemostáticos tópicos, somada à ausência de um artigo de revisão na literatura nacional sobre este tópico, nos estimulou a elaborar este manuscrito. Aqui relatamos uma revisão detalhada sobre os agentes hemostáticos tópicos mais comumente utilizados nas especialidades cirúrgicas.

ABSTRACT Hemostasis plays a critical and fundamental role in all surgical procedures. Its management has several key points that start with good operative technique and adequate anesthetic support. Certain situations, such as severe bleeding resulting from penetrating trauma, do not depend exclusively on the control of the surgical team and require the support of new solutions that decrease or control bleeding. Since ancient times, a hallmark of medicine has been to act in the control of hemorrhage, and more recently, in the facilitation of hemostasis by the application of topical agents by either manual compression or modern agents. In the last decade, the number of different topical hemostatic agents has grown dramatically. For the modern surgeon to choose the right agent at the right time, it is essential that he/she understands the mechanisms of action, the effectiveness and the possible adverse effects related to each agent. Thus, the great variety of topical hemostatics, coupled with the absence of a review article in the national literature on this topic, stimulated us to elaborate this manuscript. Here we report a detailed review of the topical hemostatic agents most commonly used in surgical specialties.

Laparoscopic uterine artery occlusion before cervical curettage in cervical ectopic pregnancy: Safe and effective for preventing massive bleeding

Cervical ectopic pregnancy is associated with high risk for massive bleeding conditions. Cervical ectopic pregnancy can usually be treated by methotrexate injection or surgery. We present 4 cases of cervical ectopic pregnancy that were treated successfully with different uterine-conserving methods. By comparing our experience of 4 cases managed in different ways, we found that laparoscopic uterine artery occlusion before cervical curettage is more effective method for preventing massive bleeding.

Local hemostatic measures in anticoagulated patients undergoing oral surgery: a systematized literature review

PURPOSE: To conduct a systematized review of the literature about the main local hemostatic measures to control postoperative bleeding in anticoagulated patients. METHODS: A systematized review of literature was performed in the electronic database Medline (PubMed) without restriction of the publication date. The eligibility criteria were studies involving maintenance of the anticoagulant therapy, prospective studies, retrospective studies, randomized clinical trials, controlled clinical studies, comparative studies, multicentric studies or case-control studies. Studies discontinuing anticoagulant therapy, case reports, literature reviews, in vitro studies, animal experiments and articles written in language not compatible with the search strategy adopted in this work were excluded. RESULTS: Twenty-four articles that met the adopted eligibility criteria were selected, enrolling 3891 subjects under anticoagulant therapy. A total of 171 cases of hemorrhage was observed. Tranexamic acid was the main local hemostatic measure used to controlling of postoperative bleeding. CONCLUSION: The local hemostatic measures proved to be effective according to previously published studies. Nevertheless, further clinical studies should be conducted to confirm this effectiveness.

Simplified hemostatic technique during laparoscopic partial nephrectomy

INTRODUCTION: Laparoscopic partial nephrectomy (LPN) has gained popularity in recent years, although it remains a challenging procedure. Herein we describe our technique of renal defect closure using sutures as the sole means of hemostasis during LPN. SURGICAL TECHNIQUE: The kidney is approached transperitoneally in a standard fashion. After the renal artery is clamped and the tumor has been excised, the defect is closed in two separate knot-free suture layers. The deep layer suture is continuous and involves deep parenchyma including the collecting system, if opened. The superficial layer suture approximates the margins of the defect using absorbable clips on one parenchymal edge only. No bolsters, glues or other additional hemostatic agents are used. RESULTS: At present this technique was applied in 34 patients. Tumor size ranged from 17-85 mm. Median warm ischemia time was 23 min (range 12-45) and estimated blood loss 55 mL (30-1000). There were no intraoperative complications or conversions to open surgery. No urine leaks or postoperative bleedings were observed. CONCLUSIONS: This simplified technique appears reliable and quick, and therefore may be attractive for many urologic surgeons. Furthermore, the avoidance of routine use of additional hemostatic maneuvers may provide an economical advantage to this approach with no compromise of the surgical outcome.

Surgical dental treatment prior to liver transplantation

Oral-source infections are a potential threat for transplant candidates because oral diseases tendto be more severe and untreated in people who have received transplants. Although not yetscientifically proven, evaluation and dental treatment during the pre-transplantation period isrecommended in order to prevent infections and resultant odontogenic-origin sepsis during thepost-transplant period, when patients receive immunosuppressive therapy. Aim: To evaluate theinvasive dental procedures for removing dental foci performed in patients scheduled for livertransplantation and its accompanying complications. Methods: The medical records of 33 prelivertransplant recipients who were undergoing invasive dental procedures were reviewed,including their laboratory tests, special handling needs and resulting complications. Results: Fiftyinvasive dental procedures were carried out on the 33 patients. Three of them were subjected tobasic periodontal treatment and 47 were subjected to multiple or simple extractions. Threesurgical procedures resulted in postoperative complications. Conclusions: Surgical interventionto remove dental foci in liver disease patients requires careful clinical evaluation, laboratory tests,knowledge and skills in the use of local and systemic hemostatic procedures, and a partnershipapproach between dentists and physicians, in order to reduce the risk of complications.

JUSTIFICATIVA E OBJETIVOS: A expectativa de vida está aumentando no mundo. Mais idosos estão se submetendo a procedimentos endovasculares percutâneos, no entanto a ocorrênciade complicações vasculares na área de acesso pode afetar o prognóstico destes pacientes. O objetivo deste estudo foi comparar as taxas de complicações vasculares na área de acesso femoral em idosos submetidos à hemostasia, mecânica ou clássica da artériafemoral após procedimentos percutâneos. MÉTODO: Estudo prospectivo, aleatório, 1:1, que envolveu 110 pacientes recrutados entre novembro de 2009 e dezembrode 2010. Foram avaliadas as seguintes complicações vasculares: hematoma, equimose, fístula arteriovenosa, pseudoaneurisma, hematoma retroperitoneal e oclusão vascular periférica. P < 0,05 foi considerado estatisticamente significante. RESULTADOS: Considerando os grupos de compressão manual e mecânica respectivamente: a média de idade foi 69,6 ± 7,3 versus 67,8 ± 6,7 anos p = 0,2. As taxas de complicações vasculares maiores na fase hospitalar (0% versus 1,8%, p = 1,0) e no seguimento de sete dias (0% versus 1,8%, p = 0.5). No seguimento clínico de sete dias foi observado que a taxa total de complicações vasculares foi maior no grupo da compressão manual (64% versus 41,8%, p = 0.02) bem como a taxa de pacientes com complicações vasculares nessa técnica (48% versus 27,3%, p = 0,03). A taxa de complicações vasculares menores não foi diferente para os grupos nos dois períodos de observação. CONCLUSÃO: Não houve diferença nas taxas de complicações vasculares (maior ou menor) entre as técnicas hemostáticas. No seguimento de sete dias, a taxa total de complicações vasculares e de pacientes com estas complicações foi menor no uso da técnica mecânica.

BACKGROUND AND OBJECTIVES: Life expectancy is increasing worldwide. More elderly people are undergoing percutaneous endovascular procedures and the occurrence of vascular complications in the site access can adversely affect the patient's prognosis. This study to compare the rates of vascular complicationsin elderly patients submitted to mechanical or classical hemostasis of the femoral artery after percutaneous procedures. METHOD: A prospective, randomized, 1:1 study, which involved 110 patients, recruited between November/09 and December/10. The following vascular complications were assessed: hematoma, ecchymosis, arteriovenous fistula, pseudoaneurysm, retroperitoneal hematoma, peripheral vascular occlusion. Was considered to be statically significant p < 0.05. RESULTS: Considering manual and mechanical compression groups respectively: the mean age was 69.6 ± 7.3 v 67.8 ± 6.7 years, p = 0.2. The rates of major vascular complications were in the hospital phase (0% versus 1.8%, p = 1.0) and the seven days follow-up (0% versus 1.8%, p = 0.5). It was observed in the clinical follow-up after seven days that the total rate of vascular complications was higher in the manual compression group (64%versus 41.8%, p = 0.02), as was the rate of patients who suffered complications with this technique (48% versus 27.3%, p = 0.03).The rate of minor vascular complications was not different for the groups in the two periods of observation. CONCLUSION: There was no difference in the rates of vascular complications (major or minor) between the hemostatics techniques. At seven day follow-up the total rates of vascular complications and the number of patients with vascular complications were smaller in the mechanical technique.

ObjectiveTo evaluate radio-frequency hemostasis in hepatectomy.MethodsFrom January 2009 to February 2011,the clinical data of 60 patients undergoing curative liver resection were divided into two groups using radio-frequency hemostasis (RFH) and clamp crushing method (CCM) respectively,RFH group (30 cases) and CCM group (30 cases).There was no difference between the 2 groups regarding the age,sex.hepatic function and tumor size.Data regarding the intra-operative and postoperative courses of the patients were analyzed.ResultsNo damage of hepatic vein occured in RFH group.Hepatic veins rupture occurred in 5 cases and massive bleeding occurred in 3 cases in CCM group.lntra-operative blood loss was significantly less in FRH group [ (219 ±62) ml] than in CCM group [ (416 ±96) ml ] (P ＜ 0.05 ).The postoperative drainage volume in RFH group was significantly less than that in CCM group on the third postoperative day.The serum ALT and T-BIL in RFH group was significantly lower than that in CCM group on postoperative day 1 and day 7 ( separately t =5.987,16.803,22.264,8.386,8.255,all P ＜0.05 ).Postoperative hepatic function in RFH group was significantly better than that in CCM group.ConclusionsThe use of radio-frequency hemostasis in hepatectomy is less traumatic,of less bleeding,faster recovery than clamp crashing method.

Tática de canulação em miniesternotomia superior para o tratamento cirúrgico de cardiopatias congênitas / Cannulation tatics in upper ministernotomy for the surgical treatment of congenital heart disease

INTRODUÇÃO: Descreveremos a técnica com a miniesternotomia superior em "L invertido" com canulação central para o tratamento de cardiopatias congênitas simples e apresenta os resultados iniciais. MÉTODOS: Foram operados 10 pacientes (idade média: 7 ± 4,2 anos; peso médio: 29,1 ± 13,5 kg), entre janeiro de 2006 e julho de 2007. RESULTADOS: Todos os defeitos foram corrigidos sem a necessidade de conversão para esternotomia total. Não ocorreu nenhum óbito ou complicação que necessitasse de reintervenção. CONCLUSÃO: A referida técnica demonstrou ser aplicável e segura na correção de determinadas cardiopatias congênitas com benefício estético e expectativa de menor deformidade torácica no futuro.
