Weighted Versus Uniform Dose of Tranexamic Acid in Patients Undergoing Primary, Knee Arthroplasty...

OsteoarthritisIntraoperative Bleeding

Hypotheses: Primary - A weighted dose of 20 mg/kg of tranexamic acid will be more efficacious than a single uniform dose of 1 gram in primary total knee arthroplasty (TKA) cases. This includes having a greater impact on decreasing blood loss without increasing the occurrence of adverse thromboembolic events in patients undergoing primary, elective total knee arthroplasty. Secondary - TA will decrease blood loss more effectively in women than in men undergoing this procedure.

Tranexamic Acid Versus Placebo to Reduce Perioperative Bleeding After Major Hepatectomy

Blood LossSurgical

Blood loss was reported as a prognostic risk factor of morbidity and overall survival after hepatic resection. The aim of this study prospective randomized was compare the efficacy of the administration of tranexamic acid versus placebo to reduce perioperative bleeding after major hepatectomy (> 3 hepatic segments).

Assessment of the Impact of Perioperative Administration of Tranexamic Acid on Bleeding After Sleeve...

Enhanced recovery after bariatric surgery imposes a significant reduction in length of hospital stay. However beneficial for the overall recovery it reduces the hospital observation time. after a laparoscopic surgery during which one of the longest resection line in surgery or anastomosis are created. Therefore, discovering possible safe and effective ways of pharmacologically reducing surgical blood loss and reducing the risk of postoperative bleeding would be an invaluable addition to the protocol. The systemic use of tranexamic acid (TXA) has been shown to be effective in many types of surgery, reducing the incidence of post-operative bleeding and thereby reducing the rate of reoperation.

EtCO2 Level to Control Intraoperative Bleeding and Improve the Quality of Surgical Field Vision...

AnesthesiaCarbon Dioxide1 more

It is unknown whether different end-tidal carbon dioxide pressure levels have a clinically significant effect on bleeding and surgical field quality in septorhinoplasty, especially during controlled hypotension. Therefore, it was aimed to investigate the effect of ventilation strategy with controlled hypocapnia on intraoperative bleeding and surgical field quality for commonly practiced in septorhinoplasty.

Comparison Between Hyperoncotic and Isooncotic Albumin to Support Blood Loss Replacement

Blood LossSurgical1 more

Fluid intravascular replacement is usually performed with either balanced crystalloids or iso-oncotic colloids, (synthetic colloids, plasma and 5% albumin). Doubts have been raised about synthetic colloids, and albumin solutions have been used more extensively. Albumin is the main protein responsible for plasma oncotic pressure and its volume expansion effect. The mobilization of extravascular fluid by infusing a hyper-oncotic solution like 20% albumin solution has been shown, causing endogenous fluid recruitment and blood volume expansion. The primary objective of this study is to compare the effect on plasma volume expansion and fluid recruitment of 3 different types of fluids (Albumin 5% and Albumin 20% and Ringer-lactate) during the hemorrhagic phase of the cystectomy procedure. Secondary objectives are the assessment of the hemodynamic parameters during surgery and the follow-up of pro-ANP and pro-BNP peptides. Glycocalyx proteins will be followed to evaluate endothelial wall shedding and microcirculation damages.

Hemorrhage

This is a single blind, randomized, prospective study comparing SURGICEL Powder with SURGICEL Original (control arm) as an adjunct to achieve hemostasis in the control of capillary, venous, and small arterial hemorrhage when ligation or other conventional methods of control are impractical or ineffective during surgery (open, laparoscopic, or thoracoscopic) in Chinese adult subjects.

Impact of Hyperoncotic Albumin to Support Blood Loss Replacement

Blood LossSurgical1 more

Fluid treatment is usually performed with either balanced crystalloid fluids or iso-oncotic colloids, (synthetic colloids, plasma and 5% albumin). Doubts have been raised about synthetic colloids (impairment of renal function and coagulation), and the natural albumin has been used more extensively. Albumin is the main protein responsible for plasma oncotic pressure and its volume expansion effect. An alternative therapeutic option is the mobilization of tissue fluid by infusing a small amount of hyper-oncotic fluid like the 20% albumin solution (endogenous fluid recruitment). The primary objective of this study is to test the effect of 20% albumin on plasma volume expansion and fluid recruitment in the frame of blood loss replacement during cystectomy using established fluid kinetic models. The investigators expect that fluid replacement with crystalloid will be better sustained intravascularly with the administration of 20% albumin and be able to recruit fluid into the vascular compartment.

Study of Fibrinogen Concentrate (Human) (FCH) to Control Bleeding During Complex Cardiovascular...

Surgical Blood LossPostoperative Blood Loss

The purpose of this study is to demonstrate that Fibrinogen Concentrate (Human)(FCH) can reduce the amount of donor blood products needed during complex cardiovascular surgery, and that it is safe and well tolerated. Subjects in this study will get either a FCH or placebo infusion during surgery. This will be in addition to the standard treatment, which is donor blood or blood products. Placebo does not contain any effective medicine. The study is randomised. This means that the likelihood that subjects will get FCH or placebo is 50%. To make the comparison between FCH and placebo as fair as possible, the study is "double blind". This means that neither the subjects nor the study doctor will know if FCH or placebo is administered. If necessary, the study doctor can find out which treatment the subjects are receiving.

Efficacy Study of Recombinant Protein (Ecallantide) to Reduce Blood Loss During Primary Coronary...

Blood LossSurgical

The primary objective of this study was to assess the efficacy and safety of 2 dose levels of ecallantide versus placebo in reducing blood loss following cardiopulmonary bypass (CPB), as measured by chest tube drainage during the first 12 hours postoperatively or until the chest tube was removed, whichever came first, in patients undergoing primary coronary artery bypass grafting (CABG), single valve repair, or single valve replacement. The secondary objective was to compare the efficacy of all ecallantide-treated participants (pooled high and low-doses) to placebo and to compare the high-dose to the low-dose ecallantide group. Other secondary objectives were to evaluate pharmacokinetics and antibody formation.
