SPSIP Versus RISS Block in Volume-Preserving VATS (SRVATS)

Detaillierte Beschreibung
Video-assisted thoracoscopic surgery (VATS) is associated with significant postoperative pain that may impair respiratory function and delay recovery. Regional anesthesia techniques are increasingly used to improve analgesia while minimizing opioid-related adverse effects.
The Serratus Posterior Superior Intercostal Plane (SPSIP) block and the Rhomboid Intercostal and Subserratus (RISS) block are novel ultrasound-guided fascial plane blocks that provide thoracic analgesia through different mechanisms. However, comparative clinical evidence regarding their efficacy in VATS patients remains limited.
This prospective, randomized, controlled study will enroll 84 adult patients scheduled for volume-preserving VATS. Participants will be randomly assigned to receive either SPSIP block or RISS block in a 1:1 ratio (42 patients per group).
The primary endpoint is the incidence of somatic pain at the chest drain insertion site at postoperative 2 hours.
Secondary endpoints include postoperative pain scores at rest and during movement, total intravenous morphine consumption during the first 24 postoperative hours, Quality of Recovery-15 (QoR-15) score at postoperative 24 hours, diaphragmatic excursion measured by ultrasonography, peak expiratory flow measurements, rescue analgesic requirements, time to first rescue analgesia, incidence of postoperative nausea and vomiting, and block-related complications.
The study has been approved by the Bursa Sehir Hospital Clinical Research Ethics Committee and will be conducted in accordance with the Declaration of Helsinki and Good Clinical Practice principles.
