Higher levels of tourniquet pressure and higher pressure gradients beneath tourniquet cuffs are associated with a higher risk of nerve-related injury. Measurement of limb occlusion pressure can help to minimize tourniquet pressure levels and pressure gradients for individual patients and individual surgical procedures. Selective use of pneumatic, wider, and contoured tourniquet cuffs reduces to...

This study investigated the clinical outcomes of early and late tourniquet release (tourniquet release after cementing the prosthesis vs tourniquet release after wound closure and pressure dressing) in total knee arthroplasty (TKA). The study was conducted by searching PubMed, Embase, Web of Science, and Cochrane Central databases for articles on randomized controlled trials comparing early and...

UNLABELLED Although the mechanism of tourniquet-induced hypertension is still unclear, plasma norepinephrine concentrations continuously increase in parallel to arterial blood pressure during tourniquet inflation. Clonidine attenuates hyperadrenergic and hyperdynamic responses. We investigated the effects of clonidine on prolonged tourniquet inflation. Twenty-nine patients scheduled for electiv...

Distal radius fractures are the most common of upper limb. It is a fracture in elderly and indiction an osteosynthesis by locked plate often posed view osteopenia. Surgical fixation distal under local anesthesia with patient wide awake without tourniquet allows intraoperative testing stability active mobilization. This technique people extensive comorbidities to avoid adverse effects commonly a...

Introduction: Ischaemic-reperfusion nerve injury has been suggested as the mechanism for post-tourniquet limb paralysis. As dexamethasone (Dex) has been shown to Prevent ischaemic-reperfusion process in some tissues, we tested the hypothesis that this drug would reduce tourniquet induced nerve injury. Methods: 36 male Wistar rats (200-250 gr) were chosen and divided randomly into 6 equal grou...

OBJECTIVE The purpose of the present study is to determine the performance of tourniquet use by the placement of the tourniquet's windlass on the extremity in four positions--medial, lateral, anterior, and posterior--to inform tourniquet instructors and develop best tourniquet practices. METHODS A HapMed™ Leg Tourniquet Trainer was used as a manikin to test the effectiveness of an emergency t...

The authors undertook a randomised prospective study to investigate the contribution of thigh tourniquets to the formation of intra-operative venous emboli during lower limb surgery. Patients were randomised to have a thigh tourniquet or no tourniquet and transoesophageal echocardiography was used to detect embolic signals in the right heart during and after knee arthroscopy. Three physicians b...

We have investigated whether the thigh tourniquet used during total knee replacement (TKR) influenced the development of postoperative wound hypoxia and was a cause of delayed wound healing. We allocated randomly 31 patients (31 TKRs) to one of three groups: 1) no tourniquet; 2) tourniquet inflated at low pressure (about 225 mmHg); and 3) tourniquet inflated to high pressure of about 350 mmHg. ...

The air tourniquet is routinely used in the surgery of the lower limbs. Circulatory and biochemical changes in the blood were investigated during the use of the tourniquet and after its removal. The blood flow was stopped by tourniquet for 60•`120 minutes under general anesthesia with intra-tracheal intubation. The results obtained were as follows. Blood pressure and CVP were sharply reduced af...

background despite several studies investigating the pathophysiologic effects of tourniquet usage in extremity surgeries, there are not enough data about these effects in adhesion release surgeries of burn patients. in the light of numerous metabolic changes of burn tissues, we tried to determine whether there are any significant differences in metabolic responses of burn tissues to tourniquet ...
