Minia University80 enrolled

Overview

There are different techniques of interscalene brachial plexus block, we aimed to evaluate the effectiveness of 3 of them as analgesia during shoulder arthroscopy surgery under general anesthesia.

Prospective randomized controlled study There were 4 groups included in our study: Group N: nerve stimulator guided interscalene brachial plexus block was done Group U: ultrasound guided interscalene brachial plexus block was done Group NU: dual guidance (using both nerve stimulator and ultrasound) Group C: control group We assessed in each group: heart rate, noninvasive blood pressure, time needed for block, onset of sensory and motor power loss and their offset, and finally patient satisfaction.
