Postpartum hemorrhage (PPH) is a leading cause of maternal morbidity. Identifying the underlying etiology rapidly through physical examination is critical for directing appropriate intervention. Pair each distinct clinical presentation of severe postpartum bleeding with its corresponding primary etiology.
- Profuse vaginal bleeding accompanied by a soft, boggy, poorly contracted uterine fundus palpable above the umbilicus.Uterine atony
- Continuous bright red bleeding despite a firm, well-contracted uterus, typically following an operative vaginal delivery.Genital tract laceration
- Hemorrhage and hypovolemic shock accompanied by a nonpalpable abdominal fundus and a fleshy mass protruding through the introitus.Uterine inversion
- Massive bleeding during attempted manual removal of a retained placenta, revealing an absent decidual cleavage plane in a patient with prior hysterotomies.Placenta accreta spectrum
Answer
The correct pairings map the physical examination findings to the '4 Ts' of postpartum hemorrhage: Tone (atony causes a boggy uterus), Trauma (lacerations cause bleeding with a firm uterus), Tissue (accreta causes an absent cleavage plane), and Uterine inversion (causing a nonpalpable fundus).
Uterine atony involves a lack of myometrial contraction, resulting in a soft, boggy uterus. Genital tract lacerations present with ongoing bright red bleeding despite adequate uterine tone (a firm uterus). Uterine inversion occurs when the fundus prolapses through the cervix, leading to a nonpalpable abdominal fundus and a visible vaginal mass. Placenta accreta spectrum involves abnormal trophoblast invasion into the myometrium, presenting as an adherent placenta lacking a normal cleavage plane.
Step-by-Step Solution
Key Concept
Differentiation of postpartum hemorrhage etiologies based on targeted physical examination findings.
Alternative Method
Memorizing the '4 Ts' of postpartum hemorrhage (Tone, Trauma, Tissue, Thrombin) provides a systematic framework to quickly mentally map each clinical presentation to its underlying cause.
