5. Study Description
Brief 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
Detailed Description
Unilateral pulmonary dysfunction occured after interscalene block due to phrenic nerve paralysis. This reduction induced vital capacity alteration and peek flow reduction.Several studies analysed dysfunction recovery duration after single injection using short (lidocaine)or intermediate (ropivacaine, bupivacaine)local anesthetic drug. Because continuous infusion prolonged block duration, phenic nerve may be also prolonged. However no study with continuous interscalene infusion have been performed for this dysfunction.
