What this Trial Is About
This research aims to compare two nerve block techniques, rhomboid intercostal plane block (RIB) and serratus posterior superior intercostal plane block (SPSIPB), to find the best method for managing pain after video-assisted thoracoscopic surgeries (VATS). Forty adult patients undergoing elective wedge resection or biopsy with ASA physical status I-III participated in this randomized, quadruple-masked trial to assess postoperative pain relief. Patients were randomly assigned to receive either the RIB or SPSIPB block after surgery but before extubation. Both blocks involved ultrasound-guided injections of 30 mL of 0.25% bupivacaine in specific muscle planes near the ribs on one side of the chest. In addition, all patients received postoperative pain medications including intravenous paracetamol, dexketoprofen, and tramadol via patient-controlled analgesia. These treatments aimed to relieve pain in the surgical area. Participants were monitored closely for 24 hours after surgery. Pain levels were measured at rest and during movement using the Numerical Rating Score at multiple time points starting once patients reached a certain recovery state. Total tramadol use, side effects like nausea or itching, and the need for extra pain medication were also recorded. The main focus was on pain scores, with tramadol consumption as a secondary measure. This detailed follow-up helped evaluate which block provided better postoperative pain control.

Duration - 2 to 4 weeks
Participants are screened for eligibility to participate in the trial.
1 visit (in-person)
Duration - Surgery day and 24 hours postoperatively
Participants undergo video-assisted thoracoscopic surgery. After surgical closure and before extubation, they receive either the Rhomboid Intercostal Plane Block or the Serratus Posterior Superior Intercostal Plane Block with 30 mL of 0.25% bupivacaine. Postoperative analgesics including paracetamol, dexketoprofen, and intravenous tramadol via patient-controlled analgesia are administered.
1 surgical procedure visit and multiple pain assessments over 24 hours
Duration - 24 hours
Participants' postoperative pain is monitored through Numerical Rating Scores at rest and during movement at 0, 1, 2, 6, 12, 18, and 24 hours. Additional analgesic use and side effects are recorded.
Pain assessments at 7 time points within 24 hours
