Abstract:
Objective Comparing the effects of ultrasound with nerve stimulation guided obtu-rator nerve block(ONB)with simple nerve stimulation guided ONB for transurethral resection of blad-der tumor(TURBT),so as to realize the validity and advantages of ultrasound with nerve stimulation guided ONB.Methods Sixty ASA Ⅰ or Ⅱ,male or female,age 39-77 years old,BMI 1 9-30 kg/m2 patients undergoing elective TURBT were randomly divided into two groups,nerve stimulation group (group S)and ultrasound and nerve stimulation group (group US).Success rate of the first puncture, visual analog scale (VAS)pain score,insertion-adductor contraction interval (ICI),puncture times corresponding to ICI,adductor strength,incidence of complications and validity were observed during and after ONB.Results There was no significant difference of the general validity,adductor strength and complication incidence between the two groups.The success rate of the first puncture was signifi-cantly higher in group US than that in group S (P < 0.01).VAS pain score,ICI and puncture times were significantly lower in group US than those in group S (P < 0.05).Conclusion Compared with simple nerve stimulation guided ONB,ultrasound with nerve stimulation guidance showed less punc-ture time,more accurate positioning and more comfort.
