Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

In a randomized controlled crossover study design, ultrasound guided lumbar plexus blocks will be performed with and without the aid of a needle tip tracking (NTT) system. Specialists in anaesthesiology with average experience in ultrasound guided peripheral nerve block (PNB) techniques will perform the blocks. 27 volunteers will be included. The primary objective is to investigate the effect of the NTT system on performance time, as a measure for improved block performance. Secondary objectives are the effects of the NTT system on dexterity, peripheral nerve block characteristics, subjective experience, and peripheral block performance.
