Summary

This study evaluates the effects of Horner's syndrome on cardiac autonomic nervous activity after interscalene brachial plexus block. Cardiac autonomic nervous activity and bilateral pupil diameters will be measured in a scotopic light condition, 30 minutes after interscalene brachial plexus block under ultrasound guidance and 15 minutes after the subsequent sitting position.

Conditions

  • Brachial Plexus Block
  • Horner Syndrome
  • Autonomic Imbalance

Interventions

PROCEDURE

Interscalene brachial plexus block

Under ultrasound guidance, the 5th to 7th cervical nerve roots are identified between anterior and middle scalene muscles and subsequently blocked.

DRUG

0.75% ropivacaine

Placement of 25 to 30 ml of 0.75% ropivacaine around the 5th to 7th cervical nerve roots
