An obstetrician is evaluating a multiparous patient at term who is in active labor with intact membranes. The fetal station is -2. To accelerate labor progress, an artificial rupture of membranes is performed. Immediately following the procedure, the fetal heart rate monitor shows a sudden, sustained bradycardia of 70/min. Pelvic examination reveals a soft, pulsating, rope-like structure protruding through the cervical os ahead of the fetal vertex. Arrange the following interventions in the most appropriate chronological order for managing this acute obstetric emergency, from the most immediate bedside action to final definitive care.
- 1Insert a hand into the vagina to manually elevate the fetal presenting part
- 2Reposition the patient into a knee-chest or steep Trendelenburg position
- 3Administer a rapid-acting intravenous tocolytic agent to halt uterine contractions
- 4Transport the patient to the operating room while maintaining continuous vaginal elevation
- 5Perform an emergent cesarean delivery
Cevap
The correct sequence for managing umbilical cord prolapse is to immediately elevate the presenting part manually, reposition the patient to utilize gravity, administer tocolytics to stop contractions, transport the patient to the OR with continuous manual elevation, and ultimately perform an emergent cesarean delivery.
Umbilical cord prolapse is a catastrophic obstetric emergency requiring a highly choreographed, sequential response to prevent fetal asphyxia. The absolute most critical first step is the immediate physical relief of cord compression; this is achieved by the provider inserting a hand into the vagina to manually elevate the fetal presenting part off the cord. Concurrently, the patient is repositioned into a knee-chest or steep Trendelenburg position to allow gravity to shift the fetus away from the pelvis. While emergency surgery is being arranged, a rapid-acting tocolytic (e.g., terbutaline) is often administered to stop uterine contractions, which would otherwise exacerbate cord compression. The patient is then transported to the operating suite with the provider maintaining continuous manual elevation of the fetal head. Finally, an emergent cesarean delivery is performed as the definitive, life-saving intervention.

Anahtar Kavram
Management of umbilical cord prolapse prioritizes the immediate relief of cord compression through manual elevation and maternal repositioning, followed by rapid medical stabilization (tocolytics) and execution of an emergent cesarean delivery.
