Placental causes of complications during birth

In this case the postpartum phase exceeds the normal duration of 30 minutes and thus also the normal blood loss of 300 ml. This retained placenta can be caused either by an incarceration in the uterus due to a filled bladder or by excessive contraction of the uterine muscles. Also due to a prolonged birth process, the force generated by the muscles is no longer sufficient to release the placenta.

Likewise, malformations of the placenta can lead to a delayed afterbirth phase. After the diagnosis of such a retained placenta, it can first be waited to see whether it will detach naturally in the following half hour. If this is not the case, depending on the cause, medication can be given to relax the muscles or empty the bladder.

In addition, the placenta can be released in most cases with the help of a certain handle by the obstetrician. If this does not succeed either, an instrumental intervention becomes necessary. If excessive blood loss of more than 500 ml occurs when the placenta is detached, this is usually atonic post-bleeding.

This occurs after an overstretched uterus, for example after multiple births or an excessive amount of amniotic fluid. Due to this muscle overstretching, there are always phases of flaccidity in which the vessels are not closed, which increases blood loss. To treat this increased after-bleeding, various drugs are given to close the vessels or the obstetrician stops them by squeezing and plugging the bleeding vessels.
