Summary

Regional anaesthesia is a frequently used procedure. Currently, blockades are increasingly carried out without nerve stimulation. The risk of nerve lesion is about 3 %. Industrial efforts frequently referred to ultrasound optimisation of the regional anaesthesia cannula. In order to optimise patient safety, the benefit of both procedures (stimulation and ultrasound) should be combined and both procedures optimised. In this study, the influence of the needle electrode size on the stimulability of the nerve ischiadicus should be determined.

Detailed description

There are various methods of performing regional anesthesia. In recent years, the focus has been on ultrasound-supported regional anaesthesia, and the stimulation methods that were often used in the past were no longer used or used less frequently. The combination of both methods may be an additional safety aspect and can contribute to an improved blocking quality. In addition to the best possible ultrasound quality, an optimal stimulation quality is also required. The investigators plan to carry out dual-guidance blockages of the ischiadic nerve with various regional anaesthesia needles (manufacturer of the used needles: Pajunk Medical Produkte GmbH, Geisingen, Germany; Teleflex Medical GmbH, Kernen, Germany). All regional anaesthesia cannulae are approved for the planned blockades of humans in Germany.

Interventions

Type	Name	Description
PROCEDURE	Regional Anesthesia Touhy	The patients receive the planned anaesthesia procedure according to the procedure to be performed. Only nerve blockages are carried out, which are considered to be analgesic useful for the planned operations on the basis of typical nerve courses. A touhy cannula is used.
PROCEDURE	Regional Anesthesia Facet	The patients receive the planned anaesthesia procedure according to the procedure to be performed. Only nerve blockages are carried out, which are considered to be analgesic useful for the planned operations on the basis of typical nerve courses. A facet cannula is used.
