Cerebral Blood Flow Evaluation With Trancranial Doppler After Interscalene Nerve Block

NCT04642612 · Status: TERMINATED · Type: OBSERVATIONAL · Enrollment: 10

Last updated 2021-09-16

No results posted yet for this study

Summary

The purpose of this study is to assess cerebral blood flow velocity (CBFV) following regional anesthesia for shoulder surgery. The results of this study will help to further understand the physiologic effect of the interscalene nerve block on cerebral blood flow.

Conditions

  • Regional Anesthesia
  • Horner Syndrome
  • Cerebral Blood Flow

Interventions

DEVICE

TCD Measurement

CBFV measurements will be acquired continuously with the patient supine and the head neutral. Analysis of CBFV measurements will be undertaken at 3 timepoints: 1. Patient awake and supine in the holding area 2. After sedation 3. After interscalene nerve block
