Abstract：Objective To evaluate the application of ultrasonographic assisted positioning technique in intraspinal anesthesia of severe obesity parturients. Methods Eighty severe obesity parturients who underwent cesarean section and combined lumbar epidural anesthesia in Beijing Obstetrics and Gynecology Hospital from July 2019 to January 2020 were selected as research subjects. According to the random number table method, they were divided into the ultrasound group (40 cases) and the control group (40 cases), of which 5 cases were converted to general anesthesia and withdrew from the study. The ultrasound group was used to ultrasound-assisted intraspinal anesthesia; the control group was performed by using the body surface marker localization method. The puncture conditions such as puncture time, puncture frequency and needle insertion depth of the two groups were compared, and the incidence of complications in the two groups were observed. Result The puncture time in the ultrasound group was shorter than that in the control group, puncture frequency was lower than that in the control group, and the differences were statistically significant (all P < 0.05); there was no significant difference in needle insertion depth between the two groups (P ＞ 0.05). No postoperative urinary retention and lower limb movement disorders were observed in both groups. The incidence of postoperative low back pain in the ultrasound group was lower than that in the control group, and the difference was statistically significant (P < 0.05). There was no significant difference in the incidence of paraesthesia and lower limb sensory disturbance between the two groups (P > 0.05). Conclusion In obesity parturients, ultrasound-assisted intraspinal anesthesia can significantly improve the success rate of puncture, shorten the puncture time, and has obvious advantages compared with traditional body surface marker localization method.
