Background: The occlusion pressure technique in upper extremity orthopeadic surgery is generally set at 250 mmHg using traditional tourniquet pressure technique. Compared to this, the pressure adjusted based on limb occlusion pressure (LOP) method is lower and was reported to generate less pain at tourniquet site and still reduce amount of blood losses without compromising the visualization of surgical field.
Objective: To compare the differences on tourniquet site pain and intraoperative blood losses between traditional tourniquet pressure and LOP-based methods in minor hand and wrist surgery.
Method: This is a retrospective study using clinical records of 29 patients who underwent minor hand and wrist surgery in Inburi hospital from September 2019 to October 2021 focusing on their pain scores in the upper arm and the volume of intraoperative blood losses regarding the two different manouvers.
Results: The tourniquet inflation pressure settings based on limb occlusion pressure method resulted in a significantly lower mean pain score compared to the traditional method with mean pain scores of 2.9 ± 0.8 versus 3.9 ±0.7, respectively (p =0.001). However, there was no significant difference in volume of intraoperative blood losses between the two techniques.
Conclusion: The tourniquet inflation pressure settings based on limb occlusion pressurecaused less tourniquet site pain compared to the traditional tourniquet pressure setting in minor hand and wrist surgery without a difference in intraoperative blood losses.
