Active clinical trials for "Postoperative Hemorrhage"

Study has been completed and is in the data analysis and manuscript writing phase of the project.

The purpose of this study is to determine if aspirin is associated with bleeding complications following a single tooth extraction

The investigators propose prospectively evaluating if adding separate sutures to the angles of the vaginal cuff before running barbed suture reduces the incidence of patient's perception of bleeding after surgery.

In recent years, with the continuous development of minimally invasive techniques, laparoscopic pancreatic surgery has also been widely used. Although the postoperative mortality rate of laparoscopic pancreatic surgery has been decreasing as the technology continues to improve and mature, the complication rate reported varies widely among centers.The definition and grading criteria of ISGPS on postoperative complications of pancreatic surgery are mostly proposed based on open pancreatic surgery, and most of the data of the later related studies are also for open pancreatic surgery, while the applicability of the definition and grading criteria in laparoscopic pancreatic surgery is still lacking in systematic The study The main purpose of this study is to investigate the applicability of the ISGPS definition and grading criteria for pancreatic fistula, postoperative bleeding and delayed gastric emptying in laparoscopic pancreatic surgery.

The standard heart-lung machine is a major trigger of systemic inflammatory reactions, hemodilution, coagulopathy or organ failure. The strict reduction of blood-artificial surface and blood-air contact might represent meaningful improvements of the extracorporeal technology with respect to organ preservation. The aim of this study is the evaluation of potential differences between a minimal extracorporeal circuit (MECC) and a conventional cardiopulmonary bypass (MOPS) system.

The effects of topical application of 3g tranexamic acid for 2 hours prior to opening of the suction drain following a total hip replacement

The primary objective of this exploratory cohort study is to describe levels of platelet reactivity in patients on a thienopyridine awaiting coronary artery bypass grafting (CABG).

The use of antifibrinolytic agents such as to reduce blood loss in congenital cardiac surgery has been described in many studies

Running title: Effect of Clopidogrel on Postoperative Bleeding in Patients undergoing Coronary Artery Bypass Surgery Title: Clopidogrel and bleeding in patients undergoing coronary artery bypass grafting. Is surgical delay necessary in patients using clopidogrel? And if so, which is the safety time interval when clopidogrel should be stopped before surgery in order to avoid bleeding and other related complications. Background: By blockade of the platelet ADP receptor, clopidogrel inhibits the binding of fibrinogen to the platelet GPIIb/IIIa receptor complex, thereby preventing platelet aggregation from ADP stimulation. Some authors suggest that the platelet function is completely recovered in 7 days after stopping clopidogrel in healthy subjects. Other researches suggest full recovery of platelet function in 3 to 5 days. Study objectives: To investigate if the interruption of the clopidogrel is necessary before CABG in order to prevent bleeding and other complications. To trace the increased risk patients for postoperative bleeding and to individualize the therapy according to TEG measurements. Design: A prospective, randomized mono- center study Patients: Patients who are receiving elective or urgent CABG surgery and are pre-treated at least 5 days before surgery with clopidogrel Primary endpoint: To determine if there are significant differences in blood loss, transfusions and rethoracotomies in the three selected groups of patients treated with clopidogrel To asses the predictive value of the TEG clot strength in postoperative bleeding in patients using Clopidogrel. Secondary endpoints: Death, myocardial infarction, stroke, respiratory failure, renal failure requiring dialysis, mediastinitis,readmission rates within 30 days from discharge, and ICU and hospital lengths of stay Risks: Using standard dose of aprotinin, we consider no increased risk in blood loss and other related complications for this three groups of patients. Possible benefits: Reduction of time delay in operating patients under treatment with clopidogrel. A more accurate time interval when clopidogrel should be stopped before surgery in order to eliminate the risk of bleeding and associated complications.

Previous randomised studies showed that radial artery catheterisation for percutaneous cardiovascular procedures has a superior safety profile than femoral access, however the confirmation of these benefits in the real world by a large, specific, observational study is still lacking. We endeavoured to assess the access site-related outcomes of any percutaneous cardiovascular procedure by designing a prospective registry monitoring a consecutive sample of patients in a short period of time at nine Roman hospitals reflecting the contemporary state of health care.
