Efficacy of ultrasound-guided bilateral erector spinae plane block for pediatric patients undergoing Nuss procedure with general anesthesia / 中华麻醉学杂志

ABSTRACT

Objective:To evaluate the efficacy of ultrasound-guided bilateral erector spinae plane (ESP) block for pediatric patients undergoing Nuss procedure with general anesthesia.Methods:Thirty-two American Society of Anesthesiologists physical status Ⅰ or Ⅱ patients, aged 4-15 yr, undergoing Nuss procedure with general anesthesia, were divided into ESP block plus general anesthesia group (group EG, n=16) and general anesthesia group (group G, n=16) using a random number table method.Bilateral ESP blocks were performed after anesthesia induction in group EG.Intravenous analgesia was performed postoperatively in both groups.Face Legs Activity Cry Consolability (FLACC) scores both at rest and during coughing were recorded on admission to postanesthesia care unit (PACU) and at 1, 6, 12, 24 and 48 h after operation.When FLACC score at rest >4, ibuprofen 5.0-7.5 mg/kg was taken orally according to the requirements of pediatric patients and their parents.The intraoperative amount of propofol and remifentanil used and postoperative requirement for fentanyl and ibuprofen were recorded.The development of postoperative hypoxia (SpO 2 <90%), nausea and vomiting, and urinary retention was recorded.The development of puncture site infection, hematoma and subcutaneous emphysema was recorded.The tracheal extubation time, duration in PACU and length of postoperative hospital stay were also recorded. Results:Compared with group G, FLACC scores at rest within 12 h after operation and during coughing within 6 h after operation were significantly decreased, the intraoperative consumption of remifentanil was reduced, the postoperative requirement for fentanyl and ibuprofen was decreased, the incidence of hypoxemia was decreased, the tracheal extubation time and duration in PACU were shortened ( P<0.05), and no significant change was found in the consumption of propofol, incidence of nausea and vomiting, or length of postoperative hospital stay in group EG ( P>0.05). Conclusion:Ultrasound-guided bilateral ESP block can reduce the consumption of opioids in the perioperative period and enhance the analgesic efficacy with a higher safety, which is helpful in promoting short-term outcomes for pediatric patients undergoing Nuss procedure with general anesthesia.
