Interventions

  • Serratus Posterior Superior Intercostal Plane (SPSIP) block — PROCEDURE
    Patients in this group will receive an ultrasound-guided Serratus Posterior Superior Intercostal Plane (SPSIP) block with 30 mL of 0.25% bupivacaine hydrochloride injected into the fascial plane between the serratus posterior superior muscle and the third rib, 30 minutes before surgery.
  • Deep Serratus Anterior Plane Block (Deep SAP) — PROCEDURE
    Patients in this group will receive an ultrasound-guided Deep Serratus Anterior Plane Block (Deep SAP) with 30 mL of 0.25% bupivacaine hydrochloride injected into the fascial plane between the serratus anterior muscle and the external intercostal muscles at the level of the 5th rib in the mid-axillary line.

Study Details

This randomized clinical trial aims to evaluate and compare the analgesic efficacy of the Serratus Posterior Superior Intercostal Plane (SPSIP) and Deep Serratus Anterior Plane Block in patients undergoing Video-Assisted Thoracoscopic Surgery. The primary outcome is Visual Analog Scale (VAS) during the first 24 hours after surgery. Secondary outcomes include total opioid consumption, requirement for rescue analgesia, block performance time, block-related and systemic side effects (hematoma, pneumothorax, local anesthetic toxicity, vascular puncture, infection), Patient satisfaction assessed using a Likert scale, Quality of recovery assessed using the QoR-15 questionnaire.
