Difficulty: HardTrauma and Burns

A 38-year-old male pedestrian is brought to the emergency department after being struck by a delivery truck at highway speeds. Upon arrival, he has agonal respirations. Physical examination reveals massive midfacial crush injuries with active oropharyngeal hemorrhage. His vital signs are temperature 35.5°C (95.9°F), blood pressure 68/35 mmHg, pulse 142/min, and respiratory rate 6/min. There are absent breath sounds over the right hemithorax and pronounced jugular venous distention. The pelvis is mechanically unstable on manual compression, and a rapidly expanding scrotal hematoma is noted. Based on Advanced Trauma Life Support (ATLS) protocols, arrange the following management steps in the most appropriate chronological order.

  1. 1Perform a surgical cricothyroidotomy
  2. 2Perform right-sided needle or finger thoracostomy
  3. 3Apply a noninvasive pelvic binder
  4. 4Perform a focused assessment with sonography for trauma (FAST)
  5. 5Transport to the radiology suite for whole-body computed tomography (CT)

Answer

The proper sequence dictates addressing Airway, then Breathing, then Circulation, followed by primary survey adjuncts, and lastly secondary definitive imaging.
According to Advanced Trauma Life Support (ATLS) principles, resuscitation of a severely injured polytrauma patient must follow the sequential ABCDE algorithm. The airway (A) must be secured first; because this patient has massive facial crush injuries and active bleeding, endotracheal intubation is likely to fail, making a surgical cricothyroidotomy the required first step. Breathing (B) is assessed next; clinical signs of a tension pneumothorax (absent breath sounds, distended neck veins) necessitate immediate decompression. Circulation (C) is then addressed; the mechanically unstable bleeding pelvis must be stabilized via a binder. Only after the primary survey (ABC) is controlled should adjuncts like the FAST exam be utilized to uncover occult intra-abdominal hemorrhage. Finally, secondary imaging like a CT scan is reserved for patients who have had their immediate life-threats managed.

Step-by-Step Solution

1
Address Airway (A) via surgical cricothyroidotomy
Secures the patient's airway
Massive midface trauma and oropharyngeal hemorrhage severely distort anatomy, making standard intubation contraindicated. A surgical airway must be established first to prevent immediate hypoxic death.
2
Address Breathing (B) via right-sided needle or finger thoracostomy
Decompresses the right hemithorax
Absent breath sounds and jugular venous distension in an unstable trauma patient suggest a right-sided tension pneumothorax. This must be relieved immediately after the airway is secured to restore venous return and oxygenation.
3
Address Circulation (C) via application of a noninvasive pelvic binder
Reduces pelvic volume and venous bleeding
An unstable pelvis and scrotal hematoma indicate a catastrophic pelvic ring disruption. Applying a binder is a rapid mechanical intervention to address hemorrhagic shock once the airway and breathing are stabilized.
4
Perform Primary Survey Adjuncts via a FAST exam
Evaluates for intraperitoneal fluid
After the ABCs are managed, a FAST exam is conducted to detect concomitant intra-abdominal bleeding that might require exploratory laparotomy.
5
Proceed to Secondary Evaluation via computed tomography (CT)
Obtains definitive imaging for operative or non-operative planning
Moving a patient to the CT scanner is dangerous unless their immediate life threats have been managed and their hemodynamics are sufficiently stabilized or well-understood.
