Filter by:The goal of this clinical trial is to compare two differential tourniquet pressure in lower extremity surgery cases. The main questions it aims to answer are: - What are the perioperative neurophysiological effects of ischemia and compression in the tissue under the tourniquet? - Are the effects of two different tourniquet pressures on neuromonitoring significantly different? - Can the ideal time of the reperfusion interval be evaluated by neuromonitoring? - Are the effects of two different tourniquet pressures on the quadriceps denervation significantly different from each other? Participants meeting the inclusion criteria will be evaluated for parameters to be used preoperatively. It will be evaluated in the 1st day, 1st week and 1-month follow-ups in the postoperative period. The investigators will compare two different tourniquet pressure ( Limb occlusion pressure +50 mmHg / + 100 mmHg) to see if it will be evaluated whether there is a significant difference in terms of quadriceps denervation, vas scores, total blood estimate volume loss, intraoperative MEP decrease, and recovery times, quadriceps tendon thickness, thigh circumfrences.
Patients with a chronic kidney disease who opt for hemodialysis, needs a well-functioning hemodialysis access. The autologous arteriovenous fistula (AVF) is recognized as the golden standard of dialysis access. Unfortunately a great number of the AVFs fail to mature, and therefore cannot be used for dialysis. A significant stenosis is a major cause of nonmaturing AVFs. Remarkable are the stenoses that seem to develop in the venous outflow tract where the vascular clamp was located during surgery. The primary aim of this study was to compare bloodless surgery using vascular clamps and a tourniquet with respect to the development of hemodynamic or anatomical significant stenosis in patients with a brachiocephalic or radiocephalic AVF.
Eighty patients were randomly assigned to either control (CON) or dexmedetomidine (DEX) group. DEX group received a loading dose of 0.5 µg/ kg of intravenous dexmedetomidine over 10 minutes, followed by a continuous infusion of 0.5 µg/kg/h until completion of the surgery. CON group received the same calculated volume of normal saline. Pain outcomes, metabolic and coagulative changes after tourniquet application, and after tourniquet release were investigated.
LLR was applied for tumors located at the lower edge and lateral segments of the liver that could be resected more easily than posterosuperior segments. With the development of technology and the growing experience of hepatobiliary surgeons, LLR has been expanded to major liver resections, anatomical resections, and donor hepatectomies by skilled surgeons. However, postoperative mortality, mobility and recovery of liver function are associated with major blood loss which is always the main cause of conversion to laparotomy and remains a challenge for surgeons. Pringle first described the method to arrest the hepatic hemorrhage by compression of the porta hepatis and this procedure was widely spread as well as in laparoscopic feild currently. Here, we described a new modified of Pringle maneuver using Bulldog to block vascular during LLR, and compared its effects with traditional pringle maneuver.
Although haemostasis aimed to maintain bloodless surgical field for better exposure for the surgeon, cosmetic impact, and decreased breakdown of repair, there is no trials regarding the impact of haemostasis techniques on surgeon satisfaction during surgery and patients reported outcomes.
Deflation of the pneumatic tourniquet used in lower limb surgery is usually associated with hemodynamic instability, metabolic and respiratory changes. These changes are usually tolerated by young, healthy patients; However, these complications are risky for elderly and cardiac patients. The aim of this study is to assess the effect of gradual deflation of thigh tourniquet on the hemodynamics and arterial blood gases compared to the usual practice
The purpose of this study is to compare the success rates of two different tourniquets that are used when placing an IV.
