Objective To observe the clinical effect of ropivacaine erector spinae plane block assisting general anesthesia in lumbar spine surgery. Methods A total of 60 cases of male patients with selective lumbar spine surgery under general anesthesia were chosen and randomly divided into control group(group C) and erector spinae plane block group(group E)(n= 30).Group C was directly treated with total intravenous anesthesia.In group E,the erector spinae were blocked with 0.375% ropivacaine before skin incision.The patient's vital signs during operative period were recorded,as well as the operation time,anesthesia time,drug dosage and satisfaction of muscle relaxation .Postoperative VAS scores at 4,8,24 and 48 h were recorded.Remedied analgesic drug use,the number of PCIA press,complications such as nausea and vomiting,patients’ satisfaction degree within 48 h of postoperative were all recorded. Results There were no statistical difference in the vital signs,operation section,operation time,anesthesia time and postoperative complications(all P>0.05) in two groups. Compared with group C,the dosage of propofol,rifentanyl and benzene sulfonate in group E were significantly reduced .In group C and group E,dosage of propofol was(1 526.2±134.5) mg and(1 305.8±212.8) mg; dosage of remifentanil was(2 452.2±232.5) μg and(2 076.8±311.6) μg; dosage of benzene sulfonate was(31.8±4.2) mg and (22.3±5.1) mg]( P<0.05 or P<0.01) .Satisfaction of muscle relaxation in the operation area of group E was significantly increased(P<0.05).The VAS scores at 4 h and 8 h after operation in group E were all significantly reduced(P<0.01).In group E,the frequency(or total) of remediation analgesic drugs usage and PCIA compressions times were significantly reduced in 48 h after surgery(P<0.01).The satisfaction degree of the patients in group E was significantly increased(P<0.01). Conclusion Ropivacaine erector spinae plane block assisting general anesthesia in lumbar spine surgery can reduce perioperative general anesthesia drug dosage,the number of postoperative remediation of analgesic drugs,PCIA compressions times,and can improve satisfaction of operative doctors and patients with anesthesia.
