Abstract: Objective To investigate the efficiency of ultrasound-guided erector spinae plane(ESP)block as an adjuvant to general anesthesia and postoperative analgesia in lumbar posterior lumbar surgery.Methods Sixty patients,29 males and 31 females,aged 18-70 years,BMI 20-27kg/m~2,falling into ASA physical status Ⅰ orⅡ,undergoing two intraoperative lumbar vertebrae with general anesthesia,were randomized into ESP block combined with PCIA group(group EP)and PCIA group(group P).Patients in the group EP received ultrasound-guided ESP block in prone position before general anesthesia whereas those in group P received only general anesthesia.All patients received PCIA after operations.The frequency of unstable hemodynamics,opioid dosage,muscle relaxant dosage were recorded.The frequency of PCIA compressions,rescue analgesic administrations,the length of hospital stay,the time of getting out of bed for exercise and activity,the flatus time,and postoperative complications were recored.Results The frequency of unstable hemodynamics in group EP was less than group P(P<0.05).The maintenance dosage of remifentanil and cis-atracurium were lower in group EP than in group P,the total amount of cis-atracurium as lower as well(P<0.01).The frequency of PCIA compressions and the administration of parecoxib sodium were notably less than that of group P(P<0.05),the time of postoperative activity and flatus in group EP were earlier than group P(P<0.05),the duration of hospital stay in group EP was less than group P(P<0.05).There was no significant difference in the incidence of nausea and vomiting between the two groups.Conclusion General anesthesia combined with ultrasound-guided erector spinae block can keep vital signs stable in lumbar posterior surgery,and can be benefit for earlier activity after surgery.
