Interscalene Block Versus Infraspinatus-Teres Minor Interfascial Plane Block for Shoulder Arthroscopy
29. juni 2026 opdateret af: Recep Aksu, TC Erciyes University
Comparison of the Effects of Interscalene Block and Infraspinatus-Teres Minor Interfascial Plane Block on Postoperative Analgesia and Diaphragmatic Function in Patients Undergoing Shoulder Arthroscopy.
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.

Detaljeret beskrivelse
Shoulder arthroscopy is associated with significant postoperative pain.
Interscalene block is widely used for analgesia but may impair diaphragmatic function because of phrenic nerve involvement.
The infraspinatus-teres minor interfascial plane block has been proposed as an alternative regional anesthesia technique that may provide adequate analgesia while preserving diaphragmatic function.
This randomized controlled trial will include 120 adult patients undergoing elective shoulder arthroscopy.
Participants will be randomized into three groups: interscalene block, infraspinatus-teres minor interfascial plane block, and control.
Pain scores, opioid consumption, time to first rescue analgesia, diaphragmatic excursion measured by ultrasound, and block-related complications will be recorded and analyzed.

Eksperimentel: Interscalene Block Group
Patients receive ultrasound-guided interscalene brachial plexus block for postoperative analgesia following shoulder surgery.
|
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.

Eksperimentel: Infraspinatus-Teres Minor Interfascial Plane Block Group
Patients receive ultrasound-guided infraspinatus-teres minor interfascial plane block for postoperative analgesia after shoulder surgery.
|
Ultrasound-guided infraspinatus-teres minor interfascial plane block is performed before induction of anesthesia for postoperative analgesia in patients undergoing shoulder arthroscopy.
