CLINICAL MATERIAL OF necessity, a very large sample of procedures needs to be gathered to give a significant amount of information, as complications from the use of tourniquets are rare. Because of their rarity and the concern of the surgeon on these occasions, it was thought that questionnaire information was likely to be quite accurate. One hundred and fifty-one members of the Australian Orth...

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.

The most common screening techniques to diagnose a patient’s illness are blood collection and intravenous procedures. To find or injection site, conventional support tools, such as latex tubing buckle-type tourniquets, generally used compress the vessels. This passive method has significant problems allergy, vulnerability site contamination potential bloodstream infection, physical damage due i...

This study examines the relationship between pneumatic tourniquet cuff size, occlusion pressure and the resulting pain. Two tourniquet cuff widths were used, a wide (14 cm) and a narrow cuff (7 cm). Twenty volunteers were divided into two groups for tourniquet application: a pressure group in which the tourniquet was inflated to a pressure equal to the systolic pressure + 100 mmHg, and a satura...

Proopiomelanocortin (POMC) is expressed in pituitary, central nervous system, and in a few peripheral tissues. This study addresses the hypothesis that metabolic stressors, such as acidosis, may induce the release of POMC derivatives into the cardiovascular system not only from the pituitary but also from other sites of POMC expression. In our study, we investigated the liberation of POMC deriv...

Ahead of Print article withdrawn by publisher AIM: Intravenous regional anesthesia (IVRA) is frequently used in patients who will undergo upper extremity surgical operations for its ease of use, rapid effectiveness and short hospitalization period. Different drug combinations have been used to overcome some systemic adverse effects and to increase the postoperative analgesic effectiveness. In o...

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...

INTRODUCTION Wide awake surgery of the hand (WASH) is a well-accepted technique in hand surgery which allows the surgeon to identify and rectify on the table of some of the inadvertent shortcomings in the surgical procedures to optimise the final outcome. The advantage, however, precludes the use of tourniquet. We describe a modified method which preserves all the advantages of WASH and allows ...

Background and Objectives: Melatonin and Ketorolac delay and minimize intraoperative tourniquet pain when used as premedication to lidocaine-based intravenous regional anesthesia (IVRA). It is unclear if Melatonin is more efficacious compared with Ketorolac. This study compared intraoperative tourniquet pain, postoperative analgesia, and side effects of using Melatonin vs. Ketorolac during outp...

BACKGROUND Digital tourniquets used in the emergency department have been scrutinized due to complications associated with their use, including neurovascular injury secondary to excessive tourniquet pressure and digital ischemia caused by a forgotten tourniquet. To minimize these risks, a conspicuous tourniquet that applies the least amount of pressure necessary to maintain hemostasis is recomm...
