Uterine atony is a condition that occurs after childbirth when the uterus is soft and weak, and the uterine muscles do not contract enough to clamp the placental blood vessels shut. This can lead to prolonged or excessive bleeding from the uterus, which is the biggest sign of uterine atony. Uterine atony is considered an emergency and requires quick action from healthcare providers to stop the bleeding as soon as possible and replace any lost blood or fluids.
Risk factors for uterine atony include prolonged labor, precipitous labor, uterine distension, fibroid uterus, chorioamnionitis, indicated magnesium sulfate infusions, and prolonged use of oxytocin. The examination of an individual with uterine atony will reveal a uterus that seems enlarged and soft, commonly referred to as “boggy.” The uterus will typically contain a significant amount of blood in its cavity and present with bleeding through the vaginal channel.
The goal of treatment for uterine atony is to stop the bleeding as soon as possible and replace any lost blood or fluids. Treatment typically begins with massaging the uterus to promote stronger contractions. Depending on the severity of the condition, this may be enough to treat uterine atony. However, in more severe cases, additional interventions may be necessary, such as medications to stimulate uterine contractions, uterine artery embolization, or surgery.
Uterine atony is a serious condition that can be fatal if not treated promptly. It is important to talk to your healthcare provider about uterine atony and if you are at risk, as knowing if you are at risk ahead of time can help you prepare.
