Combined Suprascapular and Axillary Nerve Blocks for Arthroscopic Shoulder Surgery

Arthroscopic Shoulder Surgery Clinical Trial

Official title:
Combined Suprascapular and Axillary Nerve Blocks for Sevoflurane Consumption and Postoperative Analgesia in Arthroscopic Shoulder Surgery

Clinical Trial Summary

Arthroscopic shoulder surgery is associated with severe pain postoperatively. Regional nerve block adding to general anesthesia might improve the quality of postoperative analgesia. The aim of the study is to compare the subacromial local anesthetic infiltration and the suprascapular-axillary nerve blocks combination for intraoperative sevoflurane consumption, postoperative analgesia and analgesic consumption.

Clinical Trial Description

After informed consent and with ethics approval, 60 ASA 2-3 patients scheduled for elective arthroscopic shoulder surgery will be included in this study. Patient will be divided to two groups by using computer -generated list for randomization. In group A, the surgeon will apply 20 ml of 0.250% bupivacaine to the subacromial region at the end of the procedure. In Group B, suprascapular (10 ml of 0.250% bupivacaine ) and axillary block (10 ml of 0.250% bupivacaine) will be performed with ultrasound and nerve stimulator guidance before induction of anesthesia. In all patients after standard and BIS (Bi spectral index) monitorization general anesthesia will be induced with remifentanil (10mcg iv), propofol (2.5 mg/kg iv) and rocuronium (0.5mg/kg iv). After intubation, anesthesia will be maintained with 50% O2 and N2O mixture. Hemodynamic parameters, BIS values, end-tidal sevoflurane consumption will be recorded by blind investigator. Postoperative visual analog scale (VAS) values, postoperative analgesic consumption (Tramadol, patient controlled analgesia), complications will be recorded. ;
