Effect of Interscalene Block on Ventilatory Function

• Status: Completed
• Trial end date: 2012-03-01
• Target enrollment: 0

Summary

Interscalene block with local anesthetic impairs ventilation (unilateral diaphragmatic dysfunction). Single injection of local anesthetic induced transitory dysfunction (< 24h). The investigators hypothesized that continuous interscalene block would prolonged ventilatory impairment
