Comparison of two chest wall blocks for pain after VATS

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

This randomized study compares rhomboid intercostal plane (RIB) block with serratus posterior superior intercostal plane block (SPSIPB) for postoperative analgesia after VATS. Blocks are performed after surgery but before waking, with standard analgesic care including paracetamol, dexketoprofen, and patient-controlled tramadol. Outcomes include pain scores at rest and with movement, total tramadol use, side effects, and need for extra analgesia. Primary endpoint is pain intensity (NRS); secondary endpoint is total opioid consumption. The study uses ultrasound guidance and targets specific thoracic levels to create regional anesthesia and maintain comfort after surgery.
