About this trial

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.

Treatments tested in this trial

  • Serratus Posterior Superior Intercostal Plane (SPSIP) block

    Procedure/Surgery

    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/Surgery

    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.

Trial outcomes

Primary outcomes

1

Postoperative pain intensity assessed using the Visual Analog Scale (VAS)

Postoperative pain intensity (VAS score) Postoperative pain will be assessed using the visual analog scale (VAS), ranging from 0 to 10, where 0 indicates no pain and 10 indicates the worst imaginable pain. Higher scores represent greater pain intensity. Measurements will be recorded at predefined time points within the first 24 hours after surgery.

Time frame
0, 1, 4, 8, 12, and 24 hours after surgery

Secondary outcomes

1

Total opioid consumption via patient-controlled analgesia (PCA)

Time frame
Within the first 24 hours postoperatively
2

Requirement for rescue analgesia

Time frame
Within the first 24 hours postoperatively
3

Block performance time

Time frame
During the block procedure (intraoperative period)
4

Block-related and systemic side effects

Time frame
Within the first 24 hours postoperatively
