Abstract:
Objective:To evaluate the efficacy of bilateral erector spinae plane block (ESPB) in improving intraoperative wake-up quality in the patients undergoing thoracolumbar scoliosis correction with general anesthesia.
Methods:Forty American Society of Anesthesiologists physical status Ⅱor Ⅲ patients of both sexes, aged 18-60 yr, scheduled for elective posterior approach thoracolumbar scoliosis correction, were divided into 2 groups (n=20 each) using a random number table method: control group (C group) and bilateral ESPB group (E group). Bilateral ESPB was performed through injecting 0.375% ropivacaine 15-20 ml to each site in group E. Anesthesia was induced by intravenously injecting propofol, sufentanil and cisatracurium after dexmedetomidine was intravenously infused for 10 min.Anesthesia was maintained by intravenously infusing remifentanil, propofol and dexmedetomidine.Propofol infusion was stopped and the infusion rate of remifentanil and dexmedetomidine was decreased during intraoperative wake-up test.Wake-up test was performed every 30 s starting from 5 min after stopping propofol infusion.The wake-up time, occurrence of agitation and coughing, hemodynamic changes (△MAP and △HR, the difference between MAP while stopping administration before wake-up test and maximum MAP during wake-up test, the difference between HR while stopping administration before wake-up test and maximum HR during wake-up test) and blood loss were recorded.The wake-up quality was assessed during operation.
Results:Compared with C group, the wake-up time was significantly shortened, the incidence of agitation and coughing was decreased, blood loss was reduced, △MAP and △HR were decreased, and the wake-up quality was increased in E group (P<0.05).
Conclusion:Bilateral ESPB can increase the intraoperative wake-up quality in the patients undergoing thoracolumbar scoliosis correction with general anesthesia.
