Brachial Artery Pulsatility Index in Supraclavicular Block

January 12, 2025 updated by: Mina Adolf Helmy, Cairo University

Evaluation of Brachial Artery Pulsatility Index As a Predictor of Successful Supraclavicular Block: a Prospective Observational Study

Investigators aimed to evaluated accuracy of brachial artery doppler derived indices such as change in pulsatility index, resistive index, and waveform morphology in predicting successful supraclavicular block

Detailed Description

supraclavicular brachial plexus block gives adequate anesthesia and analgesia for arm and hand surgeries. successful block was classically evaluated via assessment of both sensory and motor functions, However this carry disadvantages of subjective assessment including patient cooperation. objective monitors of successful block depend on sympasthetic mediated changes including perfusion index, thermography, and LASER doppler.

However most of these tools depend on complicated technology and special devices.

therefore it was assumed that the use of brachial artery derived indices such as pulsatility index, resistive index, and waveform morphology would provide simple, easy and economic assessment tool for successful supraclavicular brachial plexus block
