Active clinical trials for "Postoperative Hemorrhage"

Tonsillectomy is one of the most frequently performed surgical interventions in children. However, it is associated with a high incidence of PostOperative Nausea and Vomiting (PONV), severe pain and haemorrhage. There is strong evidence on the efficacy of Dexamethasone in reducing the incidence of PONV and pain after tonsillectomy, which led to consider this drug as a first line treatment in routine anaesthesia practice in such surgical setting. However, in the last decade, there have been arguments about the potential role of Dexamethasone in increasing the risk of postoperative bleeding in children and studies addressing the haemorrhage risk following administration of Dexamethasone for tonsillectomy are inconclusive.Thus, this study is aimed at providing evidence for the safety profile of Dexamethasone with regard to the risk of post-tonsillectomy bleeding in children when administered as a single intraoperative dose.

Viscoelastic hemostatic assay has been reported to be superior to predict perioperative bleeding in cardiac surgical patients compared with conventional blood coagulation test. However, the role of rotational thromboelastometry (ROTEM) in predicting perioperative bleeding and transfusion requirements in pediatric patients who undergoing surgery for congenital heart disease. Therefore, the investigators attempt to evaluate the predictability of intraoperative rotational thromboelastometry for perioperative bleeding and transfusion requirements in pediatric cardiac surgical patients by comparing with conventional coagulation test. The investigators also attempt to evaluate the correlation between ROTEM parameters, platelet count, and results of conventional coagulation test results.

Estimated blood loss is an important parameter recognized as a standard practice in anesthesiology and others medical specialties, with relevant clinical and research applications. Currently is no model capable of accurately estimate blood loss. The purpose of this study is to evaluate the accuracy of a novel model.

The purpose of this research is to determine if the oral form of a medication (tranexamic acid) to reduce bleeding can be used in place of an intravenous (IV) form, to learn the best way to give tranexamic acid: either a pill by mouth, or a solution by vein.

A retrospective review of patients who developed hematoma following breast surgery from 2003 to 2018 in a single institution was performed. The study investigated the value of closed-suction drains regarding the quantity and quality of fluid secretion for the prediction of subcutaneous hematoma in patients undergoing breast surgery procedures.

Endoscopic submucosal dissection(ESD) is a prominent minimally invasive operation technique for treating early gastrointestinal tumor. But promoting ESD is uneasy because of its complications such as postoperative bleeding, perforation and so on. So if we decrease the rate of postoperative bleeding, ESD might be better popularized. Some study indicated that hypertension was the independent risk factor of postoperative bleeding. Endoscopic center of Fudan University Zhongshan Hospital is a rich experienced medical unit in doing ESD operation in China. Referring to our experience, if we can use some special methods to find the potential bleeding spot which is not obvious during ESD operation and we coagulate it precisely, then we may control the risk of postoperative bleeding. Based on the above hypothesis, our team designed this study to examine whether increasing blood pressure during gastric ESD could help to control the risk of postoperative bleeding.

This study examined long-term incidence rates of major bleeding associated with hepatectomy. The investigators used data from Taiwan's National Health Insurance Research Database. Patients who underwent hepatectomy between 2000 and 2012 were identified by International Classification of Diseases, Ninth Revision, Clinical Modification codes. Variables including gender, age, comorbidities, and prescribed medications were matched between cases and controls. A total of 1,053 patients with hepatectomy and 4,212 matched non-hepatectomy subjects were included in this study.

The aim of the study is to evaluate if there is an association between platelet inhibition and surgery-related bleeding in patients undergoing non-cardiac surgery during dual antiplatelet therapy.

There are many different views regarding ideal duration and type of thromboprophylaxis after hip or knee surgery. An important factor in Fast-track surgery is early mobilization, which in itself is thought to prevent clotting. The investigators hypothesize that there is no increase with regards to thrombosis in patients receiving fast-track surgery with early mobilization and chemical thrombosis prophylaxis only during hospitalization.

Bleeding after total thyroidectomy remains a rare event that affects early postoperative morbidity, occurring in 0.3% up to 4.2% of cases. Intraoperative bleeding is an unpleasant complication, and it is often easily manageable though postoperative bleeding may represent a life-threatening condition for the patient. Between January 2019 to February 2022 , 250 consecutive patients were listed for thyroidectomy. The Investigators selected 178 patients and divided them in two groups based on the execution of the Valsalva Manoeuvre. The purpose of the investigator is to clarify whether the routine intraoperative execution of a Valsalva manoeuvre (VM) may affect the detection of bleeding that would otherwise remain occult and therefore may manifest in the postoperative period.
