No results posted yet for this study

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).

Conditions

  • Anesthesia
  • Pain, Shoulder
  • Pain, Postoperative

Interventions

OTHER

Intraplexus

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

OTHER

Extraplexus

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 Then, the needle will be withdrawn to the posterior surface of the brachial plexus and 10 ml of local anesthetic will be administered.
