Ante-partum haemorrhage: an update.

Ante-partum haemorrhage is an important cause of maternal and fetal morbidity and mortality, despite modern improvement in obstetric practice and transfusion service. It is defined as any vaginal bleeding from the 20th week of gestation till delivery. The initial management of ante-partum haemorrhage should concentrate on resuscitation and accurate diagnosis. The most important causes are placenta praevia and abruption accounting for more than half the cases. The numbers of cases of placenta praevia and placenta accreta are increasing with the increasing caesarean section rate. In many cases, it is not possible to make a definite diagnosis, despite all the investigations. Development of ultrasound especially transvaginal scan has helped in the definitive diagnosis and management of placenta praevia. Every unit should have a clear protocol for the management of massive haemorrhage, which should be regularly updated and rehearsed.
