Efficacy of Erector Spinae Plane Block Versus Infraclavicular Subomohyoid Block in Shoulder Surgery

Efficacy of Erector Spinae Plane Block Versus Infraclavicular Subomohyoid Block in Shoulder Surgery: A Randomized Controlled Blinded Study

The study aimed to compare Erector Spinae Plane (ESP) block versus infraclavicular subomohyoid (ISO) block in the provision of efficacy of either technique in postoperative analgesia in shoulder surgery, aiming to testing the safety of each block in terms of incidence of complications. Patients will be randomly divided into two groups, Group E will receive Erector spinae block and group I will receive infraclavicular subomohyioid block. The local anesthetic solution that will be used in both blocks will be a total volume of 30 mls 0.25%bupivacaine plus 3mg preservative free Dexamethasone. The time between recovery from anesthesia and first pain experienced, as verified by NRS ≥ 3 and first need of a rescue analgesic, will be defined as the duration of analgesia. The total dose of intravenous morphine (the rescue analgesic) used over 24 h postoperatively will be recorded.
