BackgroundThe need of a neurostimulator for a successful nerve block was questioned in different block types after ultrasound had become standard.AimTo determine the effect of neurostimulator use on block success in the costoclavicular block (CCB).MethodsSixty patients undergoing upper limb surgery were enrolled in the study. Patients using ultrasound and injection pressure manometer were divided as Group USP, and those using ultrasound, injection pressure manometer, and neurostimulator were divided as Group USPN. After block was applied, sensory and motor block levels were measured on a numeric scale. The block was considered successful when the desired score was reached or general anesthesia was not required intraoperatively. The number of successful and unsuccessful blocks for each group was summed up. The successful block rate was compared as the primary objective. Block application time, time to readiness for surgery, the number of needle passes, diaphragm paralysis rate, and complication rate were compared as secondary goals.ResultsBlock success rate was 90% (27/30) in Group USP and 96.7% (29/30) in Group USPN. There was no statistical difference in terms of block success rate. Block application time was significantly shorter in Group USP (207.2 ± 32.7 s) when compared to Group USPN (280.9 ± 70.1 s). Other secondary outcomes were similar.ConclusionNeurostimulator use did not affect block success in the CCB. Neurostimulator utilization prolonged block application time explicitly and did not change the complication rate. Ultrasound and injection pressure manometer are sufficient for a safe and successful CCB.Copyright © 2024 Copyright: © 2024 Nigerian Journal of Clinical Practice.
