Randomized Controlled Trial Comparative StudyModification of the forearm tourniquet techniques of intravenous regional anaesthesia for operations on the distal forearm and hand.
Our aim was to find out if a modified intravenous regional anaesthetic block technique, used for invasive surgical procedures on the distal forearm and hand, results in a drier operative field than traditional methods. Twenty consenting adult (age > 18) patients who were to have an operation on the distal forearm or hand were randomised into two groups (n=10 in each). The first group was using a traditional bier block, with a double upper arm tourniquet. ⋯ This benefit was not sustained postoperatively (p=0.57). Plasma lignocaine concentrations were higher in the conventional group (p=0.004). The modified technique was as safe as the conventional technique but has the benefits of a drier surgical field and improved intraoperative comfort for patients.
