“…Firstly, the majority of hand procedures undertaken under local anaesthesia, such as carpal tunnel release, trigger finger release, etc., are more easily carried out under a tourniquet and can be carried out within this time duration (Edwards et al, 2000). Secondly, previous studies performed on healthy people have identified that 20 minutes of tourniquet application is the reported average tolerance duration of an upper arm tourniquet (Edwards et al, 2000; Maury and Roy, 2002; Odinsson and Finsen, 2002; Yousif et al, 1993).
