简要总结
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
详细描述
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

研究组 & 干预措施
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.
干预措施: Measure of the minimal intensity of stimulation during ultrasound guided peripheral nerve blockade (Procedure)
结局指标
主要结局
Measurement of Minimum Intensity Stimulation
时间窗: estimated between 2 minutes and 20 minutes.
Minimal Intensity Stimulation (MIS) was measured Using a specific nerve stimulator (modified HNS 12 B. BRAUN, Melsungen, Germany) ; the value are noted in mA. \[0- 1.5\]. The time frame is only related to procedure of PNB. In other term, the period of assessment should be estimated between 2 minutes and 20 minutes.
次要结局
- tissure pressure at the target(estimated between 2 minutes and 20 minutes.)
