Abstract：
OBJECTIVE: Maternal lateral postures provide advantages during childbirth. This study aims to investigate the feasibility of assisting vacuum births in maternal lateral postures in a simulation model.
METHODS: In a simulation model, four obstetricians and four medical students were randomly allocated to perform vacuum-assisted births first in maternal lateral posture or lithotomy. A modification of Aldo Vacca\'s 5-step technique was developed to assist vacuum-assisted births in lateral posture. The lateral distance, vertical distance, and distance from the cup center to the flexion point were measured for every placement of the cup.
CONCLUSIONS: A total of 128 vacuum-assisted births were performed. The mean distance to the flexion point was 1.15 ± 0.71 cm for the lithotomy posture and 1.31 ± 0.82 cm for the lateral posture (P = 0.127). There were no statistically significant differences in vacuum extractor cup placement accuracy based on maternal posture. Performing vacuum-assisted births in maternal lateral posture is feasible in a simulation model. The technique is easy to learn, and the differences in cup placement between the lateral and lithotomy postures are small.

摘要：
目的：产妇侧位在分娩过程中具有优势。本研究旨在探讨在模拟模型中辅助产妇侧位真空分娩的可行性。
方法：在仿真模型中，4名产科医生和4名医学生被随机分配,首先以产妇侧位体位或截石术进行真空辅助分娩.开发了AldoVacca的5步技术的改进，以辅助侧卧位的真空辅助分娩。横向距离,垂直距离,每次放置杯子时，测量从杯子中心到弯曲点的距离。
结论：共进行了128例真空辅助分娩。截石位到屈曲点的平均距离为1.15±0.71cm，侧位为1.31±0.82cm（P=0.127）。基于产妇姿势的真空提取器杯放置准确性无统计学差异。在模拟模型中，以产妇侧卧位进行真空辅助分娩是可行的。该技术很容易学习，侧位和截石术姿势之间的杯子放置差异很小。
