Uterine rupture

A serious childbirth complication

Uterine rupture is a serious childbirth complication where the muscular wall of the uterus tears during pregnancy or childbirth. This condition can lead to severe maternal and fetal complications, including hemorrhage and fetal distress. Uterine rupture is considered an obstetric emergency and requires immediate medical intervention.

A transverse uterine rupture.

Causes

Uterine rupture can occur due to several factors, including:

• Previous cesarean section or uterine surgery, which can weaken the uterine wall.
• Excessive uterine stimulation from oxytocin or prostaglandins.
• Trauma to the abdomen.
• Obstructed labor or macrosomia, where the baby is unusually large.

Symptoms

The symptoms of uterine rupture can vary but often include:

• Sudden onset of abdominal pain.
• Abnormal fetal heart rate patterns.
• Vaginal bleeding.
• Loss of uterine tone.
• Maternal tachycardia and hypotension.

Diagnosis

Diagnosis of uterine rupture is primarily clinical, based on the symptoms and signs observed during labor. Ultrasound may be used to assess the condition of the uterus and the fetus, but it is not always definitive.

Treatment

Immediate surgical intervention is required to manage uterine rupture. This typically involves an emergency laparotomy to repair the uterine tear or, in some cases, a hysterectomy if the damage is extensive. Blood transfusions may be necessary to manage blood loss.

Prognosis

The prognosis for uterine rupture depends on the speed of diagnosis and treatment. Prompt medical intervention can significantly improve outcomes for both the mother and the baby. However, delays can lead to severe complications, including maternal and fetal mortality.

Prevention

Preventive measures include careful monitoring of labor, especially in women with a history of cesarean section or uterine surgery. Avoiding excessive use of labor-inducing drugs and opting for a planned cesarean delivery in high-risk cases can also reduce the risk of uterine rupture.
