Minimized extracorporeal circulation (MECC, Maquet, Cardiopulmonary AG, Hirrlingen, Germany) is an established procedure to perform coronary revascularization. Studies showed positive effects of MECC compared to conventional cardiopulmonary bypass (CCPB) procedures in terms of transfusion requirements, less inflammation reactions, and neurological impairments. Recent retrospective studies showed higher mean arterial pressure (MAP) ...

TKA can involve substantial bleeding, and the issue regarding whether vacuum drainage should be used during TKA continues to be debated as both methods have disadvantages. We therefore asked whether subcutaneous indwelling vacuum drainage is advantageous over intraarticular indwelling vacuum drainage in terms of blood drainage, bleeding-related complications, and functional ...

BACKGROUND: Early prediction of the need for massive transfusion (MT) remains difficult. We hypothesized that MT protocol (MTP) utilization would improve by identifying markers for MT (>10 units packed red blood cell [PRBC] in 24 hours) in torso gunshot wounds (GSW) requiring early transfusion and operation. METHODS: Data from all ...

PURPOSE: Cirrhotic patients waiting for liver transplantation who need dental extractions are given fresh frozen plasma and/or platelets to correct coagulopathy. This is costly and may be associated with transfusion reactions and fluid overload. We evaluated the efficacy of intranasal desmopressin as an alternative to transfusion to correct the coagulopathy ...

Treatment of the twin-twin transfusion syndrome (TTTS) via sequential selective laser photocoagulation of communicating vessels (SQLPCV) mandates ablation of donor-to-recipient arteriovenous anastomoses first. It is hypothesized that SQLPCV facilitates intraoperative transfusion to the donor, thereby minimizing donor hypovolemia and anemia. We sought to determine if postoperative changes in fetal middle ...

The inflammatory response after cardiac surgery increases vascular permeability leading to higher mortality and morbidity in the post operative time. The modified ultrafiltration (MUF) had shown benefits on respiratory, and hemodynamic in pediatric patients. This approach in adults is not well established yet. We hypothesize that modified ultrafiltration may improve ...

Failure of extracorporeal circuit (EC) function during continuous renal replacement therapy (CRRT) appears most likely due to progressive circuit clotting or, in some cases, most likely due to mechanical problems that affect flow. We aimed to study the incidence of such likely mechanical circuit failure (MCF). Design and Setting: Retrospective ...

To detail changes in adrenocorticotropic hormone (ACTH), cortisol, and aldosterone levels following cardiac surgery and to test the hypothesis that postcardiotomy infants requiring excessively high-dose vasopressor support will demonstrate adrenal insufficiency which will be proportional to cardiopulmonary bypass (CPB)/circulatory arrest times and vasopressor requirements. Prospective observational pilot study. A tertiary ...

Antifibrinolytic agents are commonly used during cardiac surgery to minimize bleeding. Because of safety concerns, aprotinin was withdrawn from the market in 2007. Since then, tranexamic acid (TXA) has become the antifibrinolytic treatment of choice in many heart centers. The safety profile of TXA has not been extensively studied. Therefore, ...

Cardiac surgery is a major consumer of blood products, and hemodilution increases transfusion requirements during cardiac surgery under CPB. As intraoperative parenteral fluids contribute to hemodilution, we evaluated the hypothesis that intraoperative fluid restriction reduces packed red-cell (PRC) use, especially in transfusion-prone adults undergoing elective cardiac surgery. 192 patients were ...

The optimal priming solution for cardiopulmonary bypass (CPB) is unclear. In this study, we evaluated the influence of high-volume priming with a modern balanced hydroxyethyl starch (HES) preparation on coagulation, inflammation, and organ function compared with an albumin-based CPB priming regimen. In 50 patients undergoing coronary artery bypass grafting, the ...

Total knee arthroplasty (TKA) is generally carried out using a tourniquet and blood loss occurring mainly post operatively is collected in drains. Tranexamic acid is an antifibrinolytic agent which decreases the total blood loss. Patients had unilateral / bilateral cemented TKA using combined spinal and epidural anaesthesia. In a double-blind ...

INTRODUCTION: A balanced volume replacement strategy is a well established concept for correcting hypovolemia using plasma adapted isotonic crystalloid solutions with a physiological electrolyte pattern and acetate as bicarbonate precursor. Recently, third-generation hydroxyethyl starch (HES) has also become available in a balanced electrolyte solution instead of normal saline. Therefore, in ...
