Abstract:
Objective:To evaluate the efficacy of rhomboid inter-costal and sub-serratus (RISS) block with ropivacaine-dexmedetomidine-dexamethasone for analgesia after thoracoscopic lobectomy.Methods:This study was a prospective, randomized, double-blind, controlled trial. From January 2021 to November 2023, 46 American Society of Anesthesiologists Physical Status classification Ⅰ-Ⅲ patients of either sex, undergoing elective video-assisted thoracoscopic lobectomy at the Second Affiliated Hospital of Nanjing Medical University, were selected and assigned into 2 groups ( n=23 each) using simple randomization: ropivacaine group (R group) and ropivacaine-dexmedetomidine-dexamethasone group (RDA group). RISS block was performed preoperatively, with 20 ml of the drug solution injected at the target points of the rhomboid-intercostal muscle and the serratus anterior-intercostal muscle. R group received 0.375% ropivacaine 40 ml, while RDA group received 40 ml of the mixture containing 0.375% ropivacaine, dexmedetomidine 1 μg/kg, and dexamethasone 8 mg. Postoperative analgesia was performed with oxycodone (When the patient′s numerical rating scale [NRS] score >4 in post-anesthesion care unit, oxycodone 2 mg was intravenously administered as needed until the NRS score <4, and then a patient-controlled analgesia pump was initiated). The time of the first postoperative analgesic requirement, NRS scores at rest and during coughing at 1, 3, 6, 12, 24 and 48 h postoperatively, cumulative consumption of oxycodone in the periods of 0-12 h, >12-24 h, and >24-48 h, time to first ambulation, and incidence of related adverse reactions within 48 h postoperatively were recorded. Results:Compared with R group, the time to the first analgesic requirement was significantly prolonged, the cumulative consumption of oxycodone in the first 0-12 h postoperatively was reduced ( P<0.001), and no statistically significant changes were found in the time to first ambulation, NRS scores at rest and during coughing, or the incidence of postoperative adverse reactions in RDA group ( P>0.05). Conclusions:RISS block using a combination of ropivacaine, dexmedetomidine and dexamethasone can significantly prolong block duration, reduce postoperative opioid analgesic consumption, and provide good safety for the patients undergoing thoracoscopic lobectomy.
