[Maternal position at the delivery and perineal trauma].
OBJECTIVE
Summary of the relation between of maternal position at the delivery and obstetrical perineal trauma.


METHODS
Review.


METHODS
Department of Gynaecology and Obstetrics, Charles University and Faculty Hospital Plzen.


CONCLUSIONS
Positions of mother at the delivery are divided in to: supine, semi-recumbent, lithotomy, lateral and upright positions - standing, sitting, squatting and kneeling. Birthing chair or stool might be applied. Outlined potential benefit of upright positions. So far there was not observed any consented negative impact of upright position on a mother or a child. Its potential positive effect has not been proved. A reduction of episiotomy, a slight increase in the second degree tears and more frequent blood lost over 500 mls has been described. The risk of anal sphincter trauma has been studied insufficiently. It appears, the different positions might involve different risks of the third degree tear. Up to now there is no reason to discourage woman from some of upright positions. Anyway she must be fully informed of a limited support and protection of perineum in an effort to reduce the risk of anal sphincter injury.
