Abstract：Objective To investigate the application value of sciatic nerve block assisted by ultrasound and never stimulator for patients with ankle surgery and to summarize related nursing measures. Methods 〓Totally 80 patients undergoing ankle surgery were randomly divided into the observation group(n=40)and the control group(n=40). The sciatic nerve block assisted by ultrasound and never stimulator was adopted in the observation, and the sciatic nerve block assisted by never stimulator was conducted in the control group. Both two groups received targeted nursing care during operation period. The blood pressure of patients was recorded before anesthesia and 5, 15, 30 minutes after anesthesia. The onset time and maintenance of anesthesia of sensory block and motor nerve block were compared between two groups. Results 〓There was a decreased fluctuation of blood pressure in control group, and blood pressure was lower in the control group than that of observation group at 5, 15, 30 minutes after anesthesia(P0.01). In terms of sensory block and motor nerve block, the observation group had a earlier onset time(P0.05), and longer maintenance of anesthesia(P0.01), compared with those of controls. Conclusion Application of ultrasound and never stimulator assisted sciatic nerve block could improve the anesthesia effect in ankle surgery. It is also required to carry out targeted nursing during operation period, in order to prevent anesthesia related complications.
