What is the first treatment when a mother bleeds excessively from her vagina after delivery?

The first treatment for a mother who is bleeding excessively from her vagina after delivery involves gently massaging her abdomen. This technique is used to encourage the uterus to contract, which can help reduce the bleeding. After childbirth, one common cause of postpartum hemorrhage is uterine atony, where the uterus fails to contract effectively. By providing gentle massage, you can stimulate uterine contractions and help control the bleeding.

The choice of administering oxygen, while important in cases where the patient may be showing signs of shock due to blood loss, is not the immediate step to take for managing excessive vaginal bleeding itself. Similarly, transportation of the patient or treating her for shock might be necessary, but they are secondary to the urgent need to address the source of the bleeding through abdominal massage. These other interventions can be initiated after attempting to manage the bleeding effectively.
