Brief 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.

Conditions

Arthroscopic Shoulder Surgery; Suprascapular Nerve Block; Axillary Nerve Block

Outcome Measures

Primary Outcomes (1)

• Postoperative VAS scores

  Ranging from 0: no pain to 10: worst pain

  Through postoperative period, an avarage of 30 minutes

Secondary Outcomes (1)

• sevoflurane consumption

  5th, 10th,20th,30th,40th,50th minutes after induction of anesthesia

Other Outcomes (1)

• Bleeding assesment

  5th, 10th,20th,30th,40th,50th minutes after induction of anesthesia

Study Arms (2)

Group A

SHAM COMPARATOR

In group A, the surgeon will apply 20 ml of 0.250% bupivacaine to the subacromial region at the end of the procedure

Procedure: Subacromial infiltration

Group B

ACTIVE COMPARATOR

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

Procedure: Suprascapular nerve- axillary nerve block combination

Interventions

Suprascapular nerve- axillary nerve block combination 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

Group B

Subacromial infiltration PROCEDURE

In group A, the surgeon will apply 20 ml of 0.250% bupivacaine to the subacromial region at the end of the procedure

Group A
