%X 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.
