Observation on the anesthetic effect of low-dose lidocaine combined with ropivacaine for ultrasound-guided lower limb nerve block in foot surgery
Objective To discuss the anesthetic effect of low-dose lidocaine combined with ropivacaine for ultrasound-guided lower limb nerve block in foot surgery.Methods A total of 80 patients undergoing foot surgery were divided into a control group and an observation group according to random number table method,with 40 cases in each group.The control group used ropivacaine for anesthesia,and the observation group used low-dose lidocaine and ropivacaine for anesthesia.The onset time and duration time of sensory nerve block and motor nerve block,anesthesia effect and adverse reactions were compared between the two groups.Results The onset time of sensory nerve block and motor nerve block in the observation group were(9.3±2.8)and(15.1±2.3)min,which were significantly shorter than those of(16.2±4.1)and(24.7±2.5)min in the control group,and the differences were statistically significant(P<0.05).There was no statistically significant difference in the duration of sensory nerve block and motor nerve block between the two groups(P>0.05).The excellent-good rate of anesthesia in the observation group was 95.0%,which was significantly higher than that of 80.0%in the control group,and the difference was statistically significant(P<0.05).The incidence of adverse reactions after anesthesia in the observation group was 10.0%,which was lower than that of 27.5%in the control group,and the difference was statistically significant(P<0.05).Conclusion Low-dose lidocaine combined with ropivacaine for ultrasound-guided lower limb nerve block is an effective anesthesia block method in foot surgery,which can effectively accelerate the onset time,with fewer adverse reactions,and is worthy of promotion and application.
