Abstract：Objective To explore the application effect of small-dose lidocaine in caudal block combined with electroacupuncture in anorectal surgery. Methods A total of 199 patients with anorectal disease who received surgical treatment in our hospital from January 2015 to January 2017 were randomly divided into two groups:experi-mental group (n=100) and control group (n=99) by random number table method. The experimental group was anesthesized using small-dose lidocaine for caudal block, whereas the control group was supplemented with electric acupuncture on the basis of anesthesia. The two groups were compared concerning anesthesia effect,muscle strength recovery time of both lower limbs after surgery and postoperative recovery time of automatic micturition, analgesic effect and duration of anesthesia, motor block, postoperative adverse reactions and patient satisfaction. Results Within 5 min of anesthesia,the excellent rate was significantly higher in experimental group (98.0%) than in the control group(85.9%),and the difference was statistically significant(P<0.05). After operation,the experimen-tal group showed a statistically significant difference (P<0.05) in recovery time of both lower extremity muscle strength and automatic micturition, duration of anaesthesia, incidence of headache, urinary retention, hypotension and tachycardia,which were shorter or lower than those in the control group.The satisfaction index of the patients in the experimental group was 91.0%,significantly higher than 72.7% in the control group(P<0.05). Conclusion In anorectal surgery, caudal block with small-dose lidocaine combined with electroacupuncture can significantly enhance anesthetic effect,ameliorate symptoms,improve patient satisfaction and ensure security.
