Zorluk: OrtaObstetric Complications

A pregnant individual at 33 weeks of gestation presents to the obstetrical triage unit reporting a sudden gush of clear vaginal fluid that occurred two hours ago. She has not experienced any abdominal pain, uterine contractions, or vaginal bleeding. Her previous pregnancy resulted in an uncomplicated vaginal delivery at term. Vital signs show a temperature of 37.2°C (99.0°F), blood pressure of 112/72 mm Hg, pulse of 88/min, and respiratory rate of 16/min. A sterile speculum examination confirms a closed external cervical os with a pool of clear fluid in the posterior vaginal fornix that turns nitrazine paper blue. Laboratory evaluation demonstrates a leukocyte count of 14,500/mm³. Continuous fetal monitoring shows a baseline heart rate of 145/min with moderate variability and no decelerations. Tocodynamometry reveals no uterine activity. Which of the following is the most appropriate next step in the management of this patient?

  1. A
    Induce labor with an intravenous oxytocin infusion
  2. B
    Administer intramuscular betamethasone, ampicillin, azithromycin, and intravenous magnesium sulfate
  3. Admit the patient, administer intramuscular betamethasone, and start ampicillin and azithromycinCevap
  4. D
    Transfer to the operating room for a primary cesarean section
  5. E
    Admit the patient, administer intramuscular betamethasone, and start intravenous meropenem and vancomycin

Cevap

Admit the patient, administer intramuscular betamethasone, and start ampicillin and azithromycin
This patient presents with preterm premature rupture of membranes (PPROM) at 33 weeks of gestation without signs of intra-amniotic infection or fetal compromise. The most appropriate next step is expectant management. This includes admission for inpatient observation, administration of intramuscular corticosteroids (e.g., betamethasone) to accelerate fetal lung maturity, and targeted latency antibiotics (typically a macrolide such as azithromycin and a beta-lactam such as ampicillin) to prolong the pregnancy and reduce the risk of ascending infection.

Adım Adım Çözüm

1
Diagnose the primary condition
Preterm premature rupture of membranes (PPROM)
The patient presents with a gush of fluid, pooling in the vaginal vault, and a positive nitrazine test prior to the onset of labor.
2
Determine the gestational age and clinical stability
The patient is at 33 weeks of gestation and is clinically stable.
Vital signs are normal, FHR tracing is reassuring, and there are no signs of chorioamnionitis. The mild leukocytosis is a physiologic change of pregnancy.
3
Select the appropriate management algorithm based on gestational age
Expectant management with corticosteroids and latency antibiotics
For uncomplicated PPROM between 24 and 34 weeks, the goal is to prolong gestation to allow fetal lung maturity. Magnesium sulfate is only added if less than 32 weeks.

Anahtar Kavram

Management of preterm premature rupture of membranes (PPROM) relies heavily on gestational age, with expectant management and latency antibiotics favored between 24 and 34 weeks, and immediate delivery favored at or after 34 weeks or if intrauterine infection occurs.
