Abstract: Post partum hemorrhage (PPH) is an emergency every obstetrician has to face, often unexpectedly .It complicates about 3.6% of all deliveries. It is potentially life threatening complication of 3
rd stage of labour and third most common cause of maternal deaths in developed world. In India it is the leading cause of maternal mortality (about 25%). According to Holland and Brews, post partum haemorrhage can be defined as a blood loss of more than 600ml after completion of the 3
rd stage.
Its quantitative definition is arbitrary and is related to the amount of blood loss in an excess of 500 ml following birth of the baby. The clinical definition which is more practical states, “any amount of bleeding from or into the genital tract following birth of the baby till the end of the puerperium which adversely affect the general condition of the patient evidenced by the rise in pulse rate and falling blood pressure is called post partum haemorrhage.
