title: Postpartum haemorrhage.
abstract: Most cases of postpartum haemorrhage are caused by uterine atony, maternal soft-tissue trauma, retained placenta or its parts, and obstetric coagulopathy. The factors most significantly associated with haemorrhage include advanced maternal age, prolonged labour, pre-eclampsia, obesity of mother, multiple pregnancy, a birth weight of more than 4000g, and previous postpartum haemorrhage. It seems that multiparity itself is only a weakly associated factor. The prophylactic use of oxytocic drugs (oxytocin or its combination with ergometrine at the third stage of labour is always recommended for decreasing the bleeding. Prostaglandins should be used as a second line treatment if uterine atony cannot be abolished by uterine massage and oxytocin infusion. In the surgical management, the role of hypogastric artery ligation is decreasing. The stepwise uterine devascularization may be a reasonable method in the most severe uncontrollable postpartum bleeding. The uterine tamponade with gauze or specific tubes may also be a useful alternative in some cases. Selective arterial embolization is a promising new method that seems to have success in controlling the heavy postpartum bleeding unresponsive to more usual measures. However, the value of this method should be evaluated in bigger series.
