Comparing three shoulder nerve blocks for pain relief and breathing effects

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

The trial compares interscalene block, anterior suprascapular block, and a pericapsular nerve group (PENG) block in patients having elective arthroscopic shoulder surgery. Participants will receive one of the three regional anesthesia techniques and have postoperative pain and respiratory function, including diaphragmatic performance, monitored. The comparison aims to identify techniques that provide adequate analgesia without the phrenic nerve blockade and diaphragmatic dysfunction seen with interscalene blocks. The study is being conducted at Ankara Etlik City Hospital and enrolls adult surgical patients with ASA I–III who give informed consent.
