Efficacy of Ultrasound-guided Axillary Nerve Block Versus Ultrasound-guided Peripheral Forearm Block in Patients Undergoing Hand Surgery

By means of an observer-blinded, mono-center, prospective, randomized controlled superiority trial, the total anesthesia-related time (sum of performance and onset times) of an ultrasound-guided distal peripheral nerve block and an ultrasound-guided axillary nerve block will be investigated in patients undergoing hand surgery. The hypothesis is that the onset-time of the ultrasound-guided distal peripheral nerve block will be faster than ultrasound-guided axillary nerve blocks, which is more suitable for hand surgery.
