Summary

The aim is to compare the postoperative analgesic and hemidiaphragmatic effects of Anterior SupraScapular Nerve Block (ASSNB) and InfraClavicular Brachial Plexus Block (ICBPB) combination versus CostoClavicular Brachial Plexus Block (CCBPB) in patients undergoing shoulder arthroscopic surgery.

Detailed description

Patients were divided into two randomized groups: Group 1 (ASSNB+ICBPB Combination group, n=15) and Group 2 (CCBPB group, n=15). All patients will receive the same standard general anesthesia per hospital protocol. All blocks will be applied with the same ultrasonography and block equipment, and by the same physician. Before the anesthesia induction, ipsilateral diaphragmatic excursion will be measured via Ultrasonography (USG). After the anesthesia induction, patients in Group 1 will receive anterior suprascapular nerve block (ASSNB) with 10 mL of 0.25% bupivacaine and infraclavicular brachial plexus block (ICBPB) with 15 mL of 0.25% bupivacaine (with a total volume of 25 mL). Patients in Group 2 will receive costoclavicular brachial plexus block (CCBPB) with 15 mL of 0.25% bupivacaine. All patients will receive Paracetamol 1gr and Dexketoprofen 50mg intravenous (IV) 10 minutes prior to skin closure. After 30 minutes of emergence from anesthesia (upon reaching 9 points on modified Aldrete scoring), ipsilateral diaphragmatic excursion will be assessed again. Pre- and postblock excursion differences will be recorded. Routine analgesic procedure consisting of 3x1gr Paracetamol and 2x50mg Dexketoprofen will be followed postoperatively for 24 hours. Numeric Rating Scale (NRS) will be used to assess postoperative pain on 1st, 6th, 12th, 18th and 24th hours after the surgery. Quality of Recovery-15 Patient Survey will be done both preoperatively for a baseline score, and postoperatively at 24th hour to assess the quality of recovery from the patients' view. Tramadol 50mg IV will be administered as a rescue analgesic for all patients if NRS score is equal to or higher than 4. Total Tramadol consumption will be calculated.
