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 groups...

Purpose. Tourniquet-induced nerve injuries have been reported in the literature, but even if electromyography abnormalities in knee surgery are frequent, only two cases of permanent femoral nerve palsies have been reported, both after prolonged tourniquet time. We report a case of tourniquet-related permanent femoral nerve palsy after knee surgery. Case Report. We report a case of a 58-year-old...

Tourniquet has long been used in TKA (Total Knee Arthroplasty) as the other orthopedic procedures for decreasing operation time and blood loss, providing better visualization of anatomic structures. While having much more advantages, these devices have a potential of serious complications, so they must be used with adequate knowledge and attention. Paralysis, compression neuropathy, compartment...

Tourniquet-induced peripheral neuropathy is at least partially attributable to excessive forces applied to the nerves beneath cuffs inflated to high pressures. Lowering the inflation pressure to the minimum necessary to obtain an effective arrest of blood flow distal to the tourniquet cuff should increase the safety of these systems. Tourniquet cuffs with widths varying from 4.5 cm to 80 cm wer...

conclusions this study showed that a pneumatic arm tourniquet as an adjunct to ivra provides acceptable analgesia following the deflation of the double- cuff tourniquet for relieving surgical pain. results the mean operation time after the deflation of the double-cuff tourniquet was 20.12 ± 6.1 minutes. moreover, the mean nrs for the post-deflation time was insignificant (nrs = 2), and only one...

aim and background: remote ischemic preconditioning introduces brief episodes of ischemia and reperfusion which reduces long term ischemia in orthopaedic surgery. the aim of this study was to evaluate hemodynamic and respiratory effects of remote ischemic preconditioning in lower extremity orthopaedic surgeries. methods: in this clinical trial 40 patients scheduled for lower extremity surgery w...

The relative importance of ischaemic and direct mechanical injury to nerves compressed by a tourniquet, in the pathogenesis of tourniquet paralysis in man has not been established. To investigate this question, conduction in ulnar or median nerve fibres has been measured in healthy subjects both at the level of the pneumatic tourniquet and distal to the tourniquet. Measurement was prior to, for...

Background: Several studies have put an effort to minimize the tourniquet pain and complications after conventionaldouble tourniquet intravenous regional anesthesia (IVRA). We expressed in our hypothesis that an upper arm singlewide tourniquet (ST) may serve a better clinical efficacy rather than the conventional upper arm double tourniquet (DT)in distal upper extremity surgeries.Methods: In th...

Tourniquet-use has been described in litera- ture as a surgical factor leading to increased post-operative hidden blood loss total knee arthroplasty (TKA). The hypothesis for this retro- spective study was that low-pressure tourniquet TKA would offer the benefits of surgery without potential negative effects on late after procedure. Therefore, evaluated (TBL) and (HBL) with or tourniquet. We re...

conclusions the study indicated advantages of this modified bier's block compared to the traditional one including ability to perform surgery on upper limb bones and considerable pain relief at surgical and tourniquet sites during the operation until one hour thereafter. results this study showed the presence of analgesia at surgical and tourniquet sites during the operation in 96% of patients,...
