The efficacy of rhomboid intercostal block for pain management after video-assisted thoracoscopic surgery: a prospective, randomized-controlled trial.

ABSTRACT

OBJECTIVE: We aimed to evaluate the efficacy of rhomboid intercostal block (RIB) for analgesia management in patients who underwent video-assisted thoracoscopic surgery. METHODS: Adult patients who underwent VATS under general anesthesia between July 2020 and June 2022 were included in the study. There was two groups in this study RIB (n = 25) vs control (n = 25) group. RIB was performed with 30 ml 0.25% bupivacaine at the end of the surgery. Surgical intercostal blockade was performed with 30 ml 0.25% bupivacaine in the control group. The patients received intravenous fentanyl patient-controlled postoperative analgesia. The numerical rating score (NRS), opioid consumption, and adverse events were recorded. RESULTS: A total of 50 patients were randomized into 2 groups. There were no significant difference in terms of the demographic data between groups (P > 0.05). Postoperative opioid consumption at 0-8, 8-16, 16-24, and 24-48 h and rescue analgesic use were significantly lower in RIB group (P < 0.05). At all times, the static/dynamic NRS were significantly lower in RIB group. The rate of nausea and itching was higher in control group (P < 0.05). CONCLUSION: US-guided RIB provides effective post-VATS analgesia.
