About

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

Full description

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
