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...

BACKGROUND Intravenous Regional Anesthesia (IVRA) is a well-known technique for producing analgesia during surgical procedures in the extremities. However, the rapid onset of pain following the deflation of a double-cuff tourniquet during IVRA is a serious disadvantage, leading patient suffering. OBJECTIVES The aim of this study was to evaluate the clinical effectiveness of a pneumatic arm to...

  Background: The pneumatic tourniquet (PT) is routinely used in upper and lower limb operations by most orthopaedic surgeons. The silicone ring tourniquet (SRT) was introduced in clinical practice the last decade. Clinical as well comparative studies in volunteers concerning its safety and efficacy have been published. The aim of this study was to investigate the postoperative effect of the si...

We report the effect of padding on the efficiency of the pneumatic tourniquet for the upper limb. Varying thicknesses of two commercially-available types of orthopaedic padding (Cellona and Velband) were applied to the arms of 20 volunteers, with three pressure transducers placed directly beneath the padding. A tourniquet was positioned over the padding and inflated to 220 mmHg. Significant red...

The literature indicates that tourniquet-induced neurological injuries are relatively common and frequently occur at a subclinical level. In order to evaluate the pressure transmitted to the major peripheral nerves of the arm by an externally applied pneumatic tourniquet, a fully implantable biomedical pressure transducer was placed adjacent the radial, median and ulnar nerves in six cadaver up...

Use of the lowest possible cuff inflation pressure should minimize the pathogenic effects of compression beneath the pneumatic tourniquet. Curved tourniquets (designed to fit conically shaped limbs) and wider tourniquets were associated with significantly lower arterial occlusion pressure (AOP) than standard, straight tourniquets on the arms and legs of 26 normal volunteers. These tourniquets w...

The effect of the pneumatic tourniquet on the incidence of postoperative deep venous thrombosis is uncertain. We carried out a controlled study comparing the incidence of deep venous thrombosis when a tourniquet was used with the incidence when a tourniquet was not used. Thrombosis was detected by radioisotope venography. The results of the study showed no difference in incidence and we conclud...

This paper reports on existing and novel transducers for improved quantitative investigations of the levels of applied pressures and pressure gradients produced on human limbs by non-pneumatic tourniquet straps, and by non-pneumatic elastic bandages and elastic rolls when used as tourniquets, for comparison to benchmark data for pneumatic tourniquet cuffs commonly used in surgery at present.

BACKGROUND Pneumatic tourniquets are medical devices that occlude blood flow to distal part of extremities and are commonly used in upper limb surgeries to provide a dry, clean and bloodless field. To decrease pressure-related injuries and potential risk of complications subjected to the high inflation pressure of pneumatic tourniquet, minimal inflation pressures are recommended. METHODS A ne...
