A 29-year-old primigravid woman at 34 weeks gestation arrives at the regional trauma center via helicopter after a severe motor vehicle collision. She was an unrestrained driver and experienced prolonged extrication. On arrival, she is unresponsive to verbal stimuli but groans to deep painful stimuli. Copious secretions and dental fragments are visible in the oropharynx. Heart rate is 138 beats per minute, blood pressure is 74/40 mm Hg, and respiratory rate is 32 breaths per minute with shallow effort. Oxygen saturation is 84% on room air. The abdomen is gravid and distinctly rigid. Arrange the following critical resuscitation steps in the most appropriate chronological sequence for this patient.
- 1Evacuate the oropharynx and secure the airway with endotracheal intubation
- 2Apply continuous manual leftward displacement of the gravid uterus
- 3Obtain bilateral large-bore peripheral venous access for rapid crystalloid infusion
- 4Conduct a focused assessment with sonography for trauma (FAST)
- 5Apply external cardiotocography for continuous fetal heart rate monitoring
Cevap
The correct sequence is to first secure the airway, followed by manually displacing the uterus to the left, then administering intravenous fluids, conducting a FAST examination, and finally initiating fetal monitoring.
Trauma resuscitation strictly follows a prioritized algorithm. The absolute highest priority is the Airway, necessitating immediate suction and intubation due to this patient's depressed mental status and physical airway obstruction (blood/teeth). Next, Circulation must be addressed. In a pregnant patient beyond 20 weeks gestation, the supine position causes the gravid uterus to compress the inferior vena cava, significantly reducing venous return and cardiac output. Therefore, left lateral uterine displacement is a vital early step to optimize preload. Once the mechanical obstruction to venous return is relieved, aggressive fluid resuscitation via large-bore intravenous access is initiated to combat hemorrhagic shock. Following stabilization of these primary components, the FAST exam serves as a rapid diagnostic adjunct to locate the source of hemorrhage. Finally, fetal monitoring is initiated during the secondary survey, strictly after maternal stabilization, because maternal survival is the prerequisite for fetal survival.

In maternal trauma, initial stabilization follows standard resuscitation protocols with the critical addition of left lateral uterine displacement to relieve aortocaval compression prior to or during fluid resuscitation. Fetal assessment is strictly deferred until maternal hemodynamics are stabilized.
