Abstract
AbstractThis randomised, observer-blinded study compared brachial plexus infraclavicular block under ultrasound guidance with, or without, nerve stimulation, for patients undergoing below-elbow surgery.Sixty-six patients, aged 18–70 years, with American Society Anesthesiologists' status I, II or III, were randomised into two groups. Brachial plexus infraclavicular block achieved success rates of 76% in the ultrasound guidance without nerve stimulation group and 82% in the ultrasound guidance with nerve stimulation group, but was not significantly different (p-value 0.55). Block supplementation rates were 18.2% in the ultrasound guidance without nerve stimulation group vs. 12.2% in the ultrasound guidance with nerve stimulation group (p-value 0.55), resulting in 100% of the ultrasound guidance without nerve stimulation group reaching complete successful block, compared to 97% of the ultrasound guidance with nerve stimulation group. The mean performance time was significantly shorter in the ultrasound guida...
