Match each clinical presentation of third-trimester bleeding or acute obstetric pain to the most likely diagnosis.

  • A 32-year-old G2P1 woman at 38 weeks gestation with a previous cesarean delivery experiences sudden, intense abdominal pain during active labor. Her contractions abruptly stop, and the fetal presenting part is no longer palpable on vaginal examination.Uterine rupture
  • A 28-year-old G3P2 woman at 36 weeks gestation reports the sudden onset of bright red vaginal bleeding that is completely painless. Abdominal examination reveals a soft, non-tender uterus.Placenta previa
  • A 26-year-old G1P0 woman at 34 weeks gestation with severe preeclampsia develops continuous, severe abdominal pain accompanied by dark vaginal bleeding. Her uterus is rigid and board-like on palpation.Placental abruption
  • A 30-year-old G2P1 woman at 37 weeks gestation undergoes artificial rupture of membranes. This is immediately followed by a gush of blood-tinged fluid and a sudden, sustained drop in the fetal heart rate.Vasa previa

Cevap

The presentations match as follows: prior cesarean with sudden pain and loss of station matches Uterine rupture; painless bleeding with a soft uterus matches Placenta previa; painful bleeding with a rigid uterus matches Placental abruption; and bleeding with immediate fetal bradycardia following membrane rupture matches Vasa previa.
Correctly identifying the etiology of third-trimester bleeding relies on evaluating the presence or absence of abdominal pain, uterine tone, and fetal status in conjunction with maternal risk factors. Placenta previa involves painless bleeding and a soft uterus. Placental abruption is characterized by painful bleeding and a rigid uterus, often in the setting of maternal hypertension. Vasa previa presents with painless bleeding and immediate fetal distress following membrane rupture. Uterine rupture is marked by sudden severe pain, cessation of contractions, and loss of fetal station, most commonly in patients with a history of a prior cesarean delivery.

Adım Adım Çözüm

1
Analyze the presentation of the patient with a prior cesarean delivery experiencing sudden pain and loss of fetal station.
This presentation correlates with uterine rupture.
A previously scarred uterus is vulnerable to tearing during labor, leading to the extrusion of the fetus into the peritoneal cavity and a cessation of coordinated uterine contractions.
2
Evaluate the patient presenting with painless, bright red bleeding and a soft uterus.
This presentation correlates with placenta previa.
Placenta previa involves placental tissue covering the internal cervical os, which bleeds painlessly as the lower uterine segment changes, without causing uterine rigidity or irritability.
3
Assess the hypertensive patient presenting with painful, dark bleeding and a rigid uterus.
This presentation correlates with placental abruption.
Premature placental separation causes retroplacental hemorrhage, leading to severe abdominal pain, uterine hypertonus, and dark vaginal bleeding.
4
Examine the patient presenting with immediate bleeding and fetal bradycardia upon membrane rupture.
This presentation correlates with vasa previa.
Unprotected fetal vessels traversing the membranes over the internal os are torn during rupture, resulting in rapid fetal exsanguination and immediate bradycardia.
