A Randomized Trial to Compare Serratus Anterior Plane Block and Erector Spinae Plane Block for Pain Management Following Thoracoscopic Surgery.

OBJECTIVE: Comparison of ultrasound (US)-guided erector spinae plane block (ESPB) and serratus anterior plane block (SAPB) in video-assisted thoracic surgery (VATS) patients. The primary outcome was to compare perioperative and postoperative (48 hours) opioid consumption. METHODS: A total of 60 patients were randomized into two groups (N = 30): an ESPB group and an SAPB group. All the patients received intravenous patient-controlled postoperative analgesia and ibuprofen 400 mg intravenously every eight hours. Visual analog scale (VAS) scores, opioid consumption, and adverse events were recorded. RESULTS: Intraoperative and postoperative opioid consumption at 0-8, 8-16, and 16-24 hours and rescue analgesic use were significantly lower in the ESPB group (P   0.05 each). CONCLUSION: US-guided ESPB may provide better pain control than SAPB after VATS. QUESTION: Even though there are studies about analgesia management after VATS, clinicians want to perform the technique that is both less invasive and more effective. FINDINGS: This randomized trial showed that US-guided ESPB provides effective analgesia compared with SAPB. MEANING: Performing single-injection ESPB reduces VAS scores and opioid consumption compared with SAPB.
