Zorluk: ZorInitial Stabilization and Triage

A 29-year-old male industrial worker is rushed to the trauma bay following extraction from a closed-space chemical fire. On arrival, he is conscious but agitated. His voice is noticeably hoarse, and he has a harsh, brassy cough. Physical examination reveals singed facial hair, carbonaceous deposits in the posterior oropharynx, and partial-thickness burns covering his anterior chest and bilateral upper extremities. Vital signs show a heart rate of 128/min, blood pressure of 115/75 mmHg, and respiratory rate of 30/min. Pulse oximetry displays 99% while receiving 100% oxygen via a non-rebreather mask. Which of the following is the most appropriate initial step in the management of this patient?

  1. A
    Administer weight-based lactated Ringer solution
  2. B
    Draw an arterial blood gas to measure carboxyhemoglobin levels
  3. Perform rapid sequence induction to secure the airwayCevap
  4. D
    Administer intravenous hydroxocobalamin
  5. E
    Perform flexible fiberoptic bronchoscopy to evaluate vocal cords

Cevap

Perform rapid sequence induction to secure the airway
The patient presents with classic signs of inhalation injury, including a closed-space fire history, progressive hoarseness, a brassy cough, singed facial hair, and carbonaceous sputum. In this setting, the upper airway is highly susceptible to rapid, life-threatening edema due to direct thermal damage. Despite normal oxygen saturation and stable blood pressure, these clinical indicators signal impending airway loss. Securing the airway early (prophylactically) is paramount; waiting until the patient develops hypoxemia or stridor often means the local anatomy has become too distorted by swelling to successfully place a breathing tube.

Adım Adım Çözüm

1
Evaluate the patient's clinical presentation according to the primary survey (ABCDE).
The patient demonstrates direct signs of severe inhalation injury (hoarseness, brassy cough, soot in oropharynx, singed facial hair).
Structured primary survey prevents clinicians from being distracted by visually dramatic injuries (like chest burns) when a more immediate threat to life exists.
2
Assess the stability and trajectory of the patient's airway.
Although oxygenation (99%) and consciousness are currently maintained, the physical exam findings indicate impending upper airway obstruction due to thermal injury and edema.
Thermal injury to the upper airway causes progressive swelling that can rapidly obliterate anatomical landmarks, making delayed airway control nearly impossible.
3
Select the immediate management priority.
Definitive airway management must be performed immediately, preempting diagnostics, antidotes, or burn fluid calculations.
In the hierarchy of resuscitation, Airway definitively precedes Circulation and diagnostic workups.

Anahtar Kavram

In patients with clinical signs of inhalation injury (e.g., hoarseness, carbonaceous sputum, singed facial hair), the immediate next step is early, prophylactic airway control before progressive edema makes endotracheal tube placement impossible.
