Summary

This prospective randomized controlled study aims to compare the effects of interscalene block, infraspinatus-teres minor interfascial plane block, and a control group on postoperative analgesia and diaphragmatic function in patients undergoing shoulder arthroscopy. A total of 120 patients will be enrolled and allocated into three groups. Postoperative pain scores, opioid consumption, rescue analgesic requirements, and diaphragmatic function will be evaluated and compared among the groups. The study seeks to determine whether the infraspinatus-teres minor interfascial plane block can provide effective postoperative analgesia with less impact on diaphragmatic function compared with interscalene block.

Conditions

  • Postoperative Pain
  • Shoulder Arthroscopic Surgeries
  • Diaphragmatic Dysfunction

Interventions

PROCEDURE

Ultrasound-Guided Interscalene Block

Ultrasound-guided interscalene brachial plexus block is performed before induction of anesthesia for postoperative analgesia in patients undergoing shoulder arthroscopy. The block is administered using ultrasound guidance according to institutional practice.

PROCEDURE

Ultrasound-Guided Infraspinatus-Teres Minor Interfascial Plane Block

Ultrasound-guided infraspinatus-teres minor interfascial plane block is performed before induction of anesthesia for postoperative analgesia in patients undergoing shoulder arthroscopy. The block is administered using ultrasound guidance according to institutional practice.
