Misoprostol does not need to be kept at a certain temperature and research into its effectiveness in reducing blood loss appears promising when compared with a placebo in a setting where it is not appropriate to use oxytocin. Misoprostol can cause unpleasant side effects such as very high body temperatures and shivering. Lower doses of misoprostol appear to be safer and cause less side effects.Giving oxytocin in a solution of saline into the umbilical vein is a method of administering the drug directly to the placental bed and uterus. However quality of evidence around this technique is poor and it is not recommended for routine use in the management of the third stage. More research is needed to ascertain whether this is an effective way of administering uterotonic drugs. As a way of treating a retained placenta, this method is not harmful and has shown low certainty evidence of effectiveness.Carbetocin compared with oxytocin produced a reduction in women who needed uterine massage and further uterotonic drugs for women having caesarean sections. There was no difference in rates of PPH in women having caesarean sections or women having vaginal deliveries when given carbetocin. Carbetocin appears to cause less adverse effects. More research is needed to find the cost effectiveness of using carbetocin.Tranexamic acid, a clot stabilizing medication, may also be used to reduce bleeding and blood transfusions in low-risk patients, however evidence as of 2015 was not strong.
Efforts to compress the uterus using the hands may be effective if other treatments do not work. The aorta may also be compressed by pressing on the abdomen. The World Health Organization has recommended the non-pneumatic anti-shock garment to help until other measures such as surgery can be carried out. Tranexamic acid has also been shown to reduce the risk of death, and has been recommended within three hours of delivery.In the developing world about 1.2% of deliveries are associated with PPH and when PPH occurred about 3% of women died. Globally it occurs about 8.7 million times and results in 44,000 to 86,000 deaths per year making it the leading cause of death during pregnancy. About 0.4 women per 100,000 deliveries die from PPH in the United Kingdom while about 150 women per 100,000 deliveries die in sub-Saharan Africa. Rates of death have decreased substantially since at least the late 1800s in the United Kingdom. Definition
Depending on the source, primary postpartum bleeding is defined as blood loss in excess of 500 ml following vaginal delivery or 1000 ml following caesarean section in the first 24 hours following birth. Secondary postpartum bleeding is that which occurs after the first day and up to six weeks after childbirth. Signs and symptoms
Symptoms generally include heavy bleeding from the vagina that doesnt slow or stop over time. Initially there may be an increased heart rate, feeling faint upon standing, and an increased respiratory rate.
