Brachial Artery Pulsatility Index in Supraclavicular Block

NCT06475638 | Completed

• 1 other identifier: pulsatility index in SCB
• Study Type: observational
• Target: 89
• Locations: 1 country
• Sites: 1

Brief Summary

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

Conditions

Brachial Plexus Anesthesia; Diagnostic Accuracy

Keywords

pulsatility index; successful block; resistive index

Outcome Measures

Primary Outcomes (1)

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

  the difference between the index before and after the block divided by the index value before the block

  baseline and at 5 minutes interval after block for 30 minutes

Secondary Outcomes (2)

• 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

Interventions
