Abstract:
Objective:To evaluate the efficacy of ultrasound-guided median interspinous in-plane approach to subarachnoid puncture in obese pregnant patients.Methods:This study was a randomized controlled trial. Eighty obese parturients who underwent elective cesarean section from March 2022 to January 2024 in our hospital were divided into 2 groups( n=40 each) by the random number table method: median interspinous in-plane approach group(group M) and paramedian interlaminar in-plane approach group(group P). After successful puncture, 0.5% ropivacaine 15 mg(3 ml) was intrathecally injected in both groups. The first-attempt success of puncture, the number of puncture attempts, operation time, the total success of puncture, and the visibility scores of the anterior and posterior union, positioning structure(lamina in group P, spinous process in group M) and puncture needle under ultrasound were recorded. Results:Compared with group P, the visibility score of positioning structure under ultrasound was significantly increased, the success rate of puncture at the first attempt was increased, the number of puncture attempts was decreased, the operation time was shortened, the total success rate of puncture was increased( P<0.05), and no significant change was found in the visibility scores of the anterior and posterior union and puncture needle in group M( P>0.05). Conclusions:For obese pregnant patients, the ultrasound-guided median interspinous in-plane approach can accurately and quickly perform subarachnoid puncture, which has more advantages than the traditional paramedian interlaminar in-plane approach.
