Abstract：Objective To compare the application effect of ultrasound-guided positioning and body surface marker localization for intraspinal anesthesia in ureteroscopic surgery.Methods A total of 100 patients,aged 18-79 years,with BMI 18.5-30.0 kg/m2,ASA Ⅰ or Ⅱ,who underwent ureteroscopic surgery in the Red Cross Hospital of Yulin City from March 2023 to May 2024 were divided into the control group(n=50)and the ultrasound group(n=50)according to random number table method.The control group performed intraspinal puncture operation using body surface marker localization method,and the ultrasound group performed intraspinal puncture operation using ultrasound-guided positioning method.The consistency rate of the two positioning methods was recorded,and the data of the first puncture success rate,puncture time,puncture times,the incidence of related complications and anesthesia effect of patients in the two groups were recorded.Results The coincidence rate of locating intervertebral space by ultrasound-guided positioning and body surface marker localization was 40％,the first success rate of the intraspinal puncture in the ultrasound group(36％)was higher than that in the control group(26％),with statistical significance(P＜0.05).The puncture time,the puncture times,and the needle adjustment times of the ultrasound group were(4.70±0.88)min,(1.32±0.55)times,and(1.82±1.00)times respectively,and the puncture time,the puncture times,and the needle adjustment times of the control group were(5.43±1.49)min,(1.82±1.00)times,(1.94±1.78)times respectively.There was significant difference between the two groups(P＜0.05).The success rate and satisfaction rate of anesthesia effect of both groups were 100％,and vasoactive drugs were not used during anesthesia,with none statistical significance(P＞0.05).The incidence of postoperative lumbago in the ultrasound group(8.0％)was lower than that in the control group(24.0％),and the incidence of abnormal sensation in the ultrasound group(2.0％)was lower than that in the control group(16.0％),with statistical significance(P＜0.05).Conclusion Ultrasound-guided intraspinal puncture operation can improve the first success rate of the intraspinal puncture and the quality of intraspinal puncture.
