Brachial Artery Pulsatility Index in Supraclavicular Block

Recruiting

• Conditions: Brachial Plexus Anesthesia

• Registration Number: NCT06475638
• Lead Sponsor: Cairo University

Brief Summary

we 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 tradtionaly 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.

we therefore 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

Primary Outcome Measures

Name	Time	Method
the change in pulsatility index as a predictor to successful supraclavicular block	baseline and at 5 minutes interval after block for 30 minutes	the difference between the index before and after the block divided by the index value before the block

Secondary Outcome Measures

Name	Time	Method
change in resistive index as a predictor for successful block	baseline then at 5 minutes interval for 30 minutes
change in waveform morphology as a predictor to successful block	baseline and within 10 minutes of block
