Brief Summary

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

The purpose of the study is define the minimal intensity of stimulation range at which the needle is closed to the nerve without penetrating its surface (epineurium layer) in ultrasound guided peripheral nerve blockade

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The needle is placed at the target under ultrasound guidance the nerve stimulator is turned on and the intensity increased until motor response is observed the Minimum Intensity Observation (MIS) is recorded before injection of local anesthetic

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Patient with ultrasound guided peripheral nerve blockade

A needle is placed at the target under ultrasound guidance, the nerve stimulator is turned on and the intensity increased until motor response is observed.

Group Type EXPERIMENTAL

Measure of the minimal intensity of stimulation during ultrasound guided peripheral nerve blockade

Intervention Type PROCEDURE

A needle is placed at the target under ultrasound guidance, the nerve stimulator is turned on and the intensity increased until motor response is observed. The Minimal Intensity of Stimulation is recorded before injection of local anesthetic
