Abstract

Background: The cause of pain when using a tourniquet is not yet verified. If there is an acknowledgment of the role of ischemia in this regard, intervention of oxygen supply can be suggested to reduce the pain. The purpose of the present study was to investigate the effect of oxygenation on the amount of pain when using the tourniquet for patients with hand surgery in an educational hospital between the beginning of 1394 and the end of 1395. Methods: A double-blind, randomized, controlled trial was carried out on patients with hand truma. Participants received either %50 inhaled oxygen or air placebo via a face mask for 3 minutes before and up to 30 minutes after upper arm tourniquet inflation to 250 mmHg. Pain scores were recorded at-2minute intervals using a validated-100mm visual analogue scale. Data analysis was performed using SPSS software. Results: A total of 385 participants enrolled in the study and, after exclusion criteria were applied, 200 were analyzed (oxygen, n = 100; air, n = 100). On average, at all points in the intervention, oxygen decreased the relative number of pain in the oxygen group compared to the placebo group to 10 mm difference in the pain visual analogue scale. Oxygen also significantly extended the time to reach visual analogue scale score of 40 mm (p=0. 008). Conclusions: Oxygen is a readily available, low-risk, low-cost treatment that significantly reduced tourniquet-associated pain in the present study and significantly increased the time taken to reach visual analogue scale score of 40 or more. The authors recommend oxygen to facilitate hand surgery under a tourniquet.
