Match each clinical presentation of an intrapartum or postpartum complication with its most likely underlying etiology.
- A patient with heavy vaginal bleeding and a soft, boggy uterus palpated above the umbilicus immediately after delivering a macrosomic neonate.Uterine atony
- A patient with a continuous trickle of bright red vaginal bleeding and a firm, midline uterus following a forceps-assisted vaginal delivery.Genital tract laceration
- A patient presenting two weeks postpartum with heavy vaginal bleeding and an echogenic mass in the uterine cavity noted on pelvic ultrasound.Retained products of conception
- A patient with sudden, severe abdominal pain, vaginal bleeding, and a rapid loss of fetal station during a trial of labor after cesarean.Uterine rupture
Answer
The presentations match their classic etiologies: a boggy uterus indicates uterine atony, a firm uterus with continuous bleeding points to a genital tract laceration, delayed bleeding with an ultrasound mass suggests retained products of conception, and sudden pain with loss of fetal station is the hallmark of uterine rupture.
Each etiology of obstetric hemorrhage has a distinct clinical signature. Uterine atony lacks myometrial tone, resulting in a boggy uterus. Genital tract lacerations present with active bleeding despite normal tone (firm uterus). Retained products typically present as delayed bleeding with residual tissue visible on imaging. Uterine rupture is characterized by sudden anatomic disruption, leading to severe pain and fetal station loss.
