Zorluk: OrtaObstetric Complications

A 34-year-old G4P3 patient at 37 weeks of gestation is brought to the emergency department by her husband due to sudden-onset, severe, and continuous lower abdominal pain accompanied by dark red vaginal bleeding. Her previous pregnancies were delivered vaginally at term without complications. She has a history of chronic hypertension. Her current blood pressure is 165/100 mm Hg, pulse is 115/min, and respirations are 20/min. Physical examination reveals a rigid, hypertonic, and diffusely tender uterus. Speculum examination confirms a moderate amount of dark blood in the vaginal vault with no active cervical lesions. The cervix is 2 cm dilated and 50% effaced. Fetal heart rate monitoring demonstrates a baseline of 90/min, minimal variability, and recurrent late decelerations. Which of the following is the most appropriate next step in management?

  1. Immediate cesarean deliveryCevap
  2. B
    Administration of intravenous terbutaline
  3. C
    Expectant management with continuous fetal monitoring
  4. D
    Reassurance for normal physiologic bloody show
  5. E
    Comprehensive transabdominal ultrasonography

Cevap

Immediate cesarean delivery is the required intervention for a severe placental abruption accompanied by acute fetal compromise.
The correct approach is emergent surgical delivery. This patient's presentation of sudden-onset, severe abdominal pain, dark vaginal bleeding, and a rigid, hypertonic uterus is classic for placental abruption (premature separation of the placenta). The fetal heart rate tracing shows profound bradycardia, minimal variability, and late decelerations, all of which signify severe uteroplacental insufficiency and acute fetal compromise. When placental abruption is accompanied by a non-reassuring fetal status and the patient is not in advanced labor (cervix only 2 cm dilated), immediate cesarean delivery is mandated to prevent fetal demise and severe maternal complications like hemorrhage and DIC.

Adım Adım Çözüm

1
Evaluate maternal and fetal stability based on vital signs and monitoring.
The mother is hypertensive and tachycardic. The fetal heart rate tracing shows bradycardia (90/min) with minimal variability and late decelerations, indicating severe hypoxia and distress.
Establishing stability dictates the urgency of the intervention.
2
Identify the underlying obstetric complication.
The classic triad of sudden continuous abdominal pain, a rigid/hypertonic uterus, and dark vaginal bleeding in a hypertensive patient strongly points to placental abruption.
Accurate diagnosis is necessary to select the correct management pathway.
3
Determine the definitive next step in management.
Because the fetus is in acute distress and vaginal delivery is not imminent (cervix is only 2 cm dilated), immediate cesarean delivery is required.
Expeditious delivery prevents fetal demise and mitigates maternal risks such as disseminated intravascular coagulation (DIC).

Anahtar Kavram

Placental abruption presenting with a rigid, tender uterus and fetal distress necessitates emergent cesarean delivery.
