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...

BACKGROUND Roux-en-Y gastric bypass (RYGBP) is presently one of the most popular surgical procedures for obesity. One of the possible long-term problems is weight regain, usually after a period of successful weight loss. Weight regain after RYGBP can be due to new eating habits, like sweet-eating or grazing, or volume eating because of impaired restriction. This paper reports our experience in ...

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 ...

A "napkin-ring" subretinal membrane is an unusual expression of subretinal proliferation associated with retinal detachment. An 80-year-old man with a total funnel-shaped retinal detachment underwent pars plana vitrectomy, 360 degrees relaxing retinotomy, excision of a subretinal napkin-ring membrane, and silicone oil injection. Histopathologic examination of the removed napkin-ring subretinal ...

BACKGROUND In this prospective study we aimed at examining the effects of pneumatic tourniquet on intraocular pressure during elective knee surgery. METHOD Twenty patients undergoing elective knee surgery under general anesthesia with tracheal intubation were inluded the study. Anesthesia was induced with pentothal, rocuronium and fentanyl, then maintained with sevoflurane and nitrous oxide i...
