Objective To investigate the feasibility of spinal anesthesia with hyperbaric ropivacaine for interspinous stabilizer implanta-tion.Methods Eighty patients undergoing lumbar stabilizer implantation in Beijing Friendship Hospital,Capital Medical University from Septem-ber 2020 to September 2023 were prospectively selected as the research objects.All patients were divided into two groups according to the random number table method:the general anesthesia group(n=40)and the spinal anesthesia group(n=40).The operation-related indicators of the two groups were observed and recorded,including operation time,anesthesia time,blood loss,intraoperative tachycardia and bradycardia,hyper-tension,and anesthesia recovery room(PACU)residence time.Postoperative pain intensity was evaluated by visual analogue scale(VAS)after the end of surgery,and the postoperative anesthetic complications was observed.Results There were no statistically significant differences in the operation time,anesthesia time,blood loss,intraoperative tachycardia and bradycardia,and the incidence of hypertension between the two groups(P＞0.05).The incidence of intraoperative hypotension in the spinal anesthesia group was 17.50％,which was significantly lower than that in the general anesthesia group(42.50％),and the PACU residence time was 0,which was shorter than that in the general anesthesia group[(24.58±9.46)min],the differences were statistically significant(P＜0.05).The postoperative VAS score of the spinal anesthesia group was(4.88±1.80)points,which was significantly lower than that of the general anesthesia group[(5.80±1.64)points],and the difference was statistically significant(P＜0.05).There was no statistically significant difference in hospitalization days between the two groups(P＞0.05).There was no statistically significant difference in the incidence of postoperative nausea,vomiting and chills between the two groups(P＞0.05).Conclusion Spinal anesthesia with hyperbaric ropivacaine can be used for lumbar stabilizer implantation.Compared with general anes-thesia,there is no difference in the anesthetic effect,and the incidence of intraoperative hypotension is lower,the postoperative analgesic effect is more exactly.
