Diagnosis
The most common sign is an abnormal slowing of the fetal heart rate, which is often detected once the patient is admitted to the hospital.
Severe abdominal pain or low blood pressure may occur when there is internal bleeding or vaginal bleeding due to uterine rupture.
Diagnosis can be challenging because symptoms often overlap with normal labor pain.
In some cases, ultrasound may reveal that the fetus has moved outside the uterine cavity.
Uterine Rupture and the Critical 18 Minutes That Can Change a Child’s Life
Research shows that in cases of uterine rupture diagnosed in hospital settings, if an emergency cesarean section is performed within 18 minutes, the baby is likely to survive with good health.
However, if delivery is delayed beyond 18 minutes, one in three infants may develop permanent brain damage.
Prevention of Uterine Rupture
Before pregnancy: Allow at least 18 months between pregnancies.
During pregnancy: Mothers should be aware of their individual risk factors, such as
Previous uterine rupture
History of cesarean section
History of uterine fibroid surgery
Large baby
Multiple pregnancy
Near delivery: Regular fetal movement counting is essential. If labor pain occurs, immediate hospital evaluation is crucial, as these pregnancies are considered high risk.
For women with a history of uterine rupture or a previous vertical uterine incision, an elective cesarean section at 36–37 weeks is recommended.
