**2.1.6 Antepartum and post partum hemorrhage**

Significant blood loss due to antepartum or postpartum hemorrhage may cause ischemic injury and lead to obstetric acute renal failure.

Antepartum hemorrhage may be due to placenta praevia or concealed hemorrhage due to abruptio placentae which is usually associated with PIH. Treatment consists of intravascular volume repletion and blood transfusions. If the acute renal failure is due to pre renal intravascular volume depletion and is corrected rapidly the patient may recover without dialysis. However if the insult is prolonged it may lead to acute tubular necrosis for which dialysis is needed.
