[Position and delivery]

It is scientifically demonstrated that sitting or squatting positions influence various parameters of uterine contraction. Our comparative study of three groups of 40 patients in a lying or sitting position or ambulatory, demonstrates as did other studies, the advantages of the sitting position or even better the ambulatory position. We think that the patients must be allowed to sit or walk if they want and if obstetrical conditions are favorable, then they should be placed in lateral decubitus when the dilatation is almost complete.
