A $24$ -year-old nulliparous woman at $39$ weeks of gestation is evaluated in the labor unit. She was admitted $20$ hours ago following spontaneous rupture of membranes. She has been having irregular, mild contractions. Her temperature is $39.0^\circ\text{C}$ ( $102.2^\circ\text{F}$ ), blood pressure is $112/72\text{ mm Hg}$ , pulse is $118/\text{min}$ , and respirations are $18/\text{min}$ . Fetal heart rate monitoring demonstrates a baseline of $175/\text{min}$ with moderate variability and no decelerations. The uterine fundus is tender to palpation. Cervical examination reveals $4\text{ cm}$ dilation and $80\%$ effacement. Purulent-appearing fluid is noted in the vaginal vault. When discussing possible interventions, the patient expresses severe anxiety about surgical procedures and states, 'I will absolutely not consent to a cesarean delivery under any circumstances, even if the baby is in distress.' She is fully conscious, competent, and understands the risks associated with her refusal. Which of the following is the most appropriate next step in management?

Intravenous administration of broad-spectrum antibiotics and oxytocin augmentationCevap
B
Observation and administration of oral acetaminophen
C
Emergent cesarean delivery under general anesthesia
D
Initiation of intravenous narrow-spectrum penicillin G monotherapy
E
Obtain a court order to mandate a cesarean delivery for fetal benefit

Cevap

Intravenous administration of broad-spectrum antibiotics and oxytocin augmentation

The patient's clinical presentation—fever, maternal and fetal tachycardia, fundal tenderness, and purulent vaginal fluid following prolonged rupture of membranes—is diagnostic of intra-amniotic infection (chorioamnionitis). The standard of care for this obstetric complication is the prompt administration of intravenous broad-spectrum antibiotics (typically ampicillin and gentamicin) and the expedition of delivery. Because there are no absolute contraindications to vaginal delivery and the fetal heart tracing is reassuring despite the tachycardia (moderate variability is present), augmenting labor with oxytocin is medically appropriate. Crucially, this management plan also strictly respects the competent patient's fundamental right to refuse surgical intervention.

Adım Adım Çözüm

Diagnose the primary obstetric complication.

The patient has intra-amniotic infection (chorioamnionitis), indicated by maternal fever (

>39.0^\circ\text{C}

), fetal tachycardia, prolonged rupture of membranes, purulent fluid, and uterine tenderness.

Accurate diagnosis dictates the need for urgent antibiotic therapy and expedition of delivery.

Determine the appropriate medical therapy.

Broad-spectrum intravenous antibiotics (e.g., ampicillin and gentamicin) must be administered.

Intra-amniotic infections are polymicrobial and require comprehensive coverage; narrow-spectrum monotherapy is inadequate.

Evaluate the route of delivery in the context of fetal status and ethical constraints.

Augmentation of labor with oxytocin is selected to expedite a vaginal delivery.

The fetal heart tracing shows moderate variability (reassuring), meaning immediate surgical rescue is not indicated. Furthermore, the patient is competent and has explicitly refused a cesarean delivery, an autonomous decision that must be legally and ethically respected.
