Identify the most likely underlying obstetric complication for each of the following acute intrapartum or postpartum presentations.
- Continuous, bright red vaginal bleeding in the presence of a firm, contracted, midline fundus following an operative vaginal delivery.Genital tract laceration
- Massive postpartum hemorrhage accompanied by a soft, boggy fundus palpable well above the umbilicus following a prolonged induction of labor.Uterine atony
- Sudden cessation of uterine contractions, acute abdominal pain, and loss of fetal station during a trial of labor after cesarean.Uterine rupture
- Severe postpartum hemorrhage, maternal shock, and a smooth, dark red mass protruding from the vagina with an abdominally nonpalpable fundus.Uterine inversion
Answer
The firm uterus with bleeding matches genital tract laceration; the boggy uterus matches uterine atony; the loss of fetal station matches uterine rupture; and the vaginal mass with missing abdominal fundus matches uterine inversion.
Each clinical scenario contains pathognomonic physical examination findings that directly identify the specific obstetric complication. Palpation of the fundus (firm, boggy, or absent) and fetal station progression are key differentiating factors.
