Uterine atony is a loss of tone in the uterine musculature. Normally, contraction of the uterine muscle compresses the vessels and reduces flow. This increases the likelihood of coagulation and prevents bleeds. Thus, lack of uterine muscle contraction can cause an acute hemorrhage. Clinically, 75-80% of postpartum hemorrhages are due to uterine atony.

Risk factors
Many factors can contribute to the loss of uterine muscle tone, including:[1]
- overdistention of the uterus
- multiple gestations
- polyhydramnios
- fetal macrosomia
- prolonged labor
- oxytocin augmentation of labor
- grand multiparity (having given birth 5 or more times)
- precipitous labor (labor lasting less than 3 hours)
- magnesium sulfate treatment of preeclampsia
- chorioamnionitis
- halogenated anesthetics
- uterine leiomyomata
Treatment
The first step in management of uterine atony is uterine massage. The next step is pharmacological therapies, the first of which is oxytocin, used because it initiates rhythmic contractions of the uterus, compressing the spiral arteries which should reduce bleeding. The next step in the pharmacological management is the use of methylergometrine, which is an ergot derivative, much like that use in the abortive treatment of migraines. Its side effect of hypertension means its use should not be used in those with hypertension or pre-eclampsia. In those with hypertension, the use of prostaglandin F2α is indicated (but beware of its use in patients with asthma). Another option Carbetocin and Carboprost where Oxytocin and ergometrin is inappropriate.
