Filter by:This trial is a phase III multicentre blinded randomised controlled clinical non-inferiority trial of cryopreserved platelets vs. conventional liquid-stored platelets for the management of surgical bleeding. The aim of the study is to assess the efficacy, safety and cost effectiveness of cryopreserved platelets, compared to conventional liquid-stored platelets, for the management of surgical bleeding. This trial will recruit cardiac surgical patients deemed to be at high risk of surgical bleeding and who may potentially require transfusion of platelets. It is estimated to require 808 high-risk cardiac surgical patients to be recruited, to obtain 202 patients who receive transfused study platelets for surgical bleeding.
This study will evaluate the performance of the Quantra System comprised of the Quantra Hemostasis Analyzer with the Quantra QPlus Cartridge in patients undergoing cardiac surgery utilizing cardiopulmonary bypass, including the placement of a ventricular access device.
Tonsillectomy is one of the commonest procedures performed in otolaryngology and one of its major complications is post-tonsillectomy bleeding. The goal of this study was to assess the effectiveness of Surgicel without bipolar cautery in achieving primary hemostasis in tonsillectomy. The patient that were enrolled in this retrospective study were patients who underwent tonsillectomy and achieved hemostasis either by Surgicel (group A) or bipolar cautery (group B). Our results showed that there was no statistical significant difference between the two techniques in terms of post-operative bleeding events.
This study compares the effect of starting intravenous oxytocin infusion early before uterine incision versus late after umbilical cord clamping on the blood loss during elective cesarean section
The aim is to conduct a double-dummy multi-centre randomized controlled clinical trial of application of topical dose of tranexamic acid (TxA) versus the usual intravenous TxA in patients undergoing on-pump cardiac surgery.
The purpose of this study is to investigate whether the saline-coupled bipolar sealer compared to the unipolar electrocautery provides superior hemostasis in patients undergoing primary unilateral total knee arthroplasty. This will be a prospective, randomized, single-blinded, non-inferiority study in patients scheduled for a primary unilateral total knee arthroplasty (TKA) with Dr. Eugene Krauss or Dr. Ayal Segal. The restriction of this study to two surgeons will limit variations in the outcomes being measured due to differences in surgical technique.
This study will evaluate the performance of the Quantra System comprised of the Quantra Hemostasis Analyzer with the QPlus Cartridge in patients taking anitplatelet medication that are scheduled to undergo cardiac surgery.
The primary objective of this multicentric observational study is to define the role of intraoperative temperature decrease (defined as reduction of at least 1 ° C during surgery) as haemorrhagic risk factor, evaluated as reduction of at least 1 gr / dl of hemoglobin, and to correlate it with the need for transfusion. Secondary objectives are infections and complications affecting other organs and systems incidence in the first week after surgery.
Although angiographic embolization has been introduced for preoperative management of spine metastases in 1975 and is suggested today by many authors in the management of such pathologies, it needs to be confirmed by RCT. It is a minimally invasive procedure, not free from complications. The recent meta-analyzes, due to the limited number of patients included are not exhaustive about the effectiveness of embolization in the reduction of the intraoperative bleeding, especially in the context of poor / moderate metastasis vascularization. We want to evaluate the efficacy of preoperative angiographic embolization of intermediate / poor vascularized spine metastases in reducing intraoperative blood loss during excision surgery.
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.
