Blood was collected by venepuncture from nine healthy subjects over a ten minute period before applying a standard tourniquet, and over a ten minute period afterwards. Plasma ionised calcium was unaltered by the tourniquet, whereas total calcium, total protein and albumin in serum increased modestly. However, there was no effect on total calcium adjusted for albumin. Even without albumin adjust...

Prospective evaluation of repeated standard tourniquet testing as a diagnostic indicator of dengue infection was done. Included were patients admitted to a children's hospital in Kuala Lumpur on a clinical suspicion of dengue infection based on the World Health Organization (WHO) criteria. A standard method of tourniquet was performed on 79 patients on a daily basis following admission. subject...

Although Chinese cobra snakebite is the most common type of snake venenation in China, it still lacks a comprehensive and systematic description. Hence, we aimed to study Chinese cobra bite cases with particular attention to demography, epidemiology and clinical profile. In this study, a total of 292 cases of Chinese cobra snakebite, presenting between January 1, 2008 and December 31, 2012, wer...

The enzyme levels of muscle energy metabolism were studied in eight male meniscectomy patients before and 10 minutes after release of the tourniquet and on the third post-operative day. The average tourniquet time was 65.1 min. The muscle samples were taken from the vastus lateralis muscles; the healthy side served as the control. The greatest enzyme changes 10 min after release of the tourniqu...

BACKGROUND When capsaicin is injected intradermally, hyperalgesia develops around the injection site. The authors observed that volunteers report painful sensations in the skin remote from the injection site during tourniquet constriction of the affected extremity. METHODS Each volunteer received an intradermal injection of capsaicin on the volar forearm, followed by intermittent tourniquet c...

We have recently demonstrated that the use of a tourniquet to locate the vein prior to blood sampling may affect red blood cell (RBC) deformability and aggregation, even if the tourniquet is quickly removed after insertion of the needle into the vein. However, in clinical practice, the tourniquet is usually kept in place until blood sampling is completed. The present study tested the effects of...

OBJECTIVE This study was conducted to associate tourniquet use and survival in casualty care over a decade of war in order to provide evidence to emergency medical personnel for the implementation and efficacy of tourniquet use in a large trauma system. METHODS This survey is a retrospective review of data extracted from a trauma registry. The decade (2001-2010) outcome trend analysis of tour...

A model of tourniquet ischaemia was developed in the hind limb of the rat, and the metabolic changes that occurred in the calf muscles were monitored by the non-invasive technique of phosphorus-31 nuclear magnetic resonance spectroscopy. During ischaemia the intramyocellular pH became acidic as the level of phosphocreatine declined and that of inorganic phosphate rose. Phosphocreatine was no lo...

A tourniquet is often used in total knee arthroplasty resulting in improved visualization of structures, reduced intraoperative bleeding and better cementation. The risks include deep vein thrombosis and pulmonary embolism. To quantify the case for or against tourniquet use, we carried out a systematic review and meta-analysis of selected randomized controlled trials. Ten studies were included ...
