SPSIP Versus RISS Block in Volume-Preserving VATS

Condition(s) studied

Investigational drug(s) / intervention(s)

Serratus posterior superior intercostal plane block: Ultrasound-guided Serratus Posterior Superior Intercostal Plane (SPSIP) block performed before induction of general anesthesia using local anesthetic for postoperative analgesia in patients undergoing video-assisted thoracic surgery.

Rhomboid Intercostal and Subserratus Block: Ultrasound-guided Rhomboid Intercostal and Subserratus (RISS) block performed before induction of general anesthesia using local anesthetic for postoperative analgesia in patients undergoing video-assisted thoracic surgery.

Study summary

This prospective randomized controlled study aims to compare the effects of Serratus Posterior Superior Intercostal Plane (SPSIP) block and Rhomboid Intercostal and Subserratus (RISS) block on postoperative pain, respiratory function, and recovery quality in patients undergoing volume-preserving video-assisted thoracoscopic surgery (VATS). Eighty-four patients will be randomized in a 1:1 ratio to receive either SPSIP block or RISS block. The primary outcome is the incidence of somatic pain at the chest drain insertion site at postoperative 2 hours. Secondary outcomes include pain scores, opioid consumption, quality of recovery, diaphragmatic function, pulmonary function, rescue analgesic requirements, postoperative nausea and vomiting, and block-related complications.

Eligibility

Primary outcome measure(s)

• Incidence of Somatic Pain at Chest Tube Insertion Site — Postoperative 2 hours
  Incidence of somatic pain localized at the chest tube insertion site, defined as sharp localized pain aggravated by coughing or deep inspiration, recorded as present or absent.
