Effect of Local Anesthetic Concentration (0.2% Ropivacaine vs 0.1% Ropivacaine) on Phrenic Nerve Function, Pulmonary Function, and Analgesia After Ultrasound-guided Interscalene Brachial Plexus Block for Shoulder Arthroscopy
In Brief
A clinical study evaluating ropivacaine for Shoulder Arthroscopy. Completed, enrolled 50 participants.
Detailed Summary
The objective of our study is to compare the degree of phrenic nerve blockade after interscalene block using 0.1% ropivacaine or 0.2% ropivacaine. Our hypothesis is that using a lower concentration of local anesthetic will result in lesser degree of phrenic nerve block. 40 patients will be enrolled. Half will receive the block with 0.1% ropivacaine and half with 0.2% ropivacaine. Phrenic nerve and diaphragm function will be assessed by bedside spirometry and ultrasound visualization.
