Filter by:The goal of this clinical trial is to learn if the administration of tranexamic acid can reduce the necessity of blood transfusions in adult patients undergoing major abdominal surgery. . It will also inform about safety of tranexamic acid in this setting. The main question it aims to answer is: Does tranexamic acid lower the probabilty of receiving at least one blood transfusion during or after surgery? Participants will compare tranexamic acid o a placebo (a look-alike substance that contains no drug) to see if tranexamic acid works to reduce the necessity of a blood transfusion.
Although tonsillectomy is one of the most commonly performed surgeries, a review of literature reveals no articles dealing with the study of intraoperative blood loss in tonsillectomy and adenotonsillectomy according to the use of nondepolarizing muscle relaxants. The primary aim of our trial will be to compare blood loss in the operating theatre and postoperatively in two groups of children having adenotonsillectomy. The trial numbers will be randomised in blocks.
Evaluation of DOACs treatment on post-extraction bleeding
Is B-Lynch transverse compression suture safe and effective in controlling excessive blood loss during conservative management of women with placenta previa?
Intraoperative cell salvage is commonly used in surgeries that carry a major hemorrhagic risk to reduce the administration of allogeneic red blood cells and thus improve the outcome for the patient. When processing the salvaged blood, however, a large part of the patient's plasma is washed out. This is a disadvantage with regard to an optimal coagulation status after these types of surgeries, especially liver transplantation. There are currently various cell saver systems on the market. According to the manufacturers, the plasma is returned to the patient in different quantities as part of the processing procedure. Thus, it can be assumed that in addition to red blood cells, platelets (part of plasma) are re-transfused and contribute to an optimized coagulation. Unfortunately, there is a lack of studies in this regard in the liver transplant surgery population. The investigators aim to study the performance of two different cell saver devices regarding preservation of platelet number and function.
The purpose of this study is to evaluate the effect of epinephrine in irrigation fluid for visual clarity in ankle arthroscopic surgery.
Most osteotomies and apicoectomies in periapical surgeries are performed by surgical carbide or diamond burs. But greater pressure is applied during cutting which causes more thermal and mechanical damage to the bone. Also, when it comes in contact with soft tissues like nerves or vessels it results in profuse bleeding which affects vision in surgery and neurosensory disturbance at a later stage along with the deposition of metal shavings and bony particles resulting in impaired healing. The main advantages of piezoelectric surgery in various studies are highlighted as selective hard tissue cutting and sparing soft tissue, so even if it comes in contact with vessels, nerve or Schneiderian membrane it does not result in profuse bleeding, postoperative nerve damage or perforation.
Surgeons will label surgical videos of laparoscopic pancreaticoduodenectomy with bleeding information from multicenter. The labeled surgical video will be used as training material to train the algorithmic model so as to build an artificial intelligence algorithm that can automatically identify intraoperative bleeding in this surgery. Then, we will test the performance capability of the algorithm.
Pancreatic enucleation could preserve more healthy pancreatic tissues and functions with a low recurrence risk. However, conventional enucleation can cause significant intraoperative bleeding, especially in which tumors in the pancreatic head, neck, and uncinate process of pancreas, as these tissues are rich in blood supply, mainly including the abdominal trunk and the superior mesenteric artery. In this study, we developed a novel method to control the pancreatic blood flow in laparoscopic enucleation--blocking the abdominal trunk and superior mesenteric artery with vascular occlusion clips in the process of resection, and evaluated its effectiveness and safety.
In this study, we analyze the common bleeding characteristics in laparoscopic pancreaticoduodenectomy by reviewing and annotating bleeding information from previous surgical videos as well as surgical operation OSATS technique scores. From there, we reflect on the correlation between surgical operating technique and intraoperative bleeding, as well as on the correlation between intraoperative bleeding and short-term postoperative outcomes.
