About this study

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

Inclusion criteria

  • ASA 1 undergoing forearm or hand surgery

Exclusion criteria

  • patient refusal allergy to local anesthetics fracture humerus Diabetes Melitus peripheral vascular disease

Treatment and study plan

brachial artery doppler

Device

brachial artery doppler evaluation before and after supraclavicular block

Primary outcomes

  1. the change in pulsatility index as a predictor to successful supraclavicular block

    Time frame: 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 outcomes

  1. change in resistive index as a predictor for successful block

    Time frame: baseline then at 5 minutes interval for 30 minutes

  2. change in waveform morphology as a predictor to successful block

    Time frame: baseline and within 10 minutes of block
