Effect of Intraplexus and Extraplexus Interscalene Block Approaches on the Incidence of Rebound Pain in Arthroscopic Shoulder Surgery: A Prospective, Randomized, Double-Blind Clinical Study
Status: Recruiting
Location: See location...
Intervention Type: Other
Study Type: Interventional
Study Phase: Not Applicable
SUMMARY
In this study, the hypothesis that local anesthesia, not directly injected into the nerve root, may reduce the incidence of rebound pain in the interscalene block with an extraplexus approach during arthroscopic shoulder surgeries will be investigated. Rebound pain is defined as a short-term but severe pain before and after the resolution of the interscalene block and will be evaluated using the Numerical Rating Scale (NRS) (NRS ≥ 7).

Treatments
Active_comparator: Intraplexus approach in interscalene block
The block needle will be advanced from the middle scalene muscle in a posterior-anterior direction and advanced between the C5-C6 nerve roots and the injection will be performed
Active_comparator: Extraplexus approach in interscalene block
The block needle will first be advanced above the C5 nerve root and towards the anterior part of the brachial plexus and 10 ml of local anesthetic will be injected. Then, the needle will be withdrawn to the posterior surface of the brachial plexus and 10 ml of local anesthetic will be administered.
