A 3-year-old boy is brought to the emergency department by his parents after vomiting a large amount of bright red blood. He has a past medical history of biliary atresia, for which he underwent a Kasai hepatoportoenterostomy during infancy, and subsequent portal hypertension. On presentation, the child appears lethargic and pale. His temperature is 37.1°C (98.8°F), heart rate is 165/min, blood pressure is 70/40 mm Hg, and respiratory rate is 28/min. He has another episode of voluminous hematemesis while in the resuscitation bay. Arrange the following management steps in the most appropriate chronological order for this patient.
- 1Perform rapid sequence endotracheal intubation.
- 2Establish two large-bore intravenous lines and administer isotonic crystalloids.
- 3Initiate intravenous octreotide and prophylactic ceftriaxone.
- 4Perform an emergent upper gastrointestinal endoscopy for variceal band ligation.
Answer
The correct chronological sequence is: 1) Perform rapid sequence endotracheal intubation, 2) Establish two large-bore intravenous lines and administer isotonic crystalloids, 3) Initiate intravenous octreotide and prophylactic ceftriaxone, 4) Perform an emergent upper gastrointestinal endoscopy for variceal band ligation.
In any acute emergency, the Advanced Trauma Life Support (ATLS) and Pediatric Advanced Life Support (PALS) protocols dictate addressing Airway, Breathing, and Circulation (ABCs) in that strict order. This 3-year-old child presents with hemorrhagic shock and massive hematemesis secondary to portal hypertension (biliary atresia history). Because he is 'lethargic' and actively vomiting blood, his airway reflexes are compromised, making endotracheal intubation the absolute first priority to prevent fatal aspiration. Once the airway is protected, attention shifts to Circulation: establishing two large-bore IVs and rapidly infusing isotonic crystalloids (and/or packed red blood cells) to reverse hypotension. Only after the ABCs are stabilized should condition-specific medical therapy be initiated. In variceal bleeding, this consists of octreotide (to reduce splanchnic blood flow) and prophylactic antibiotics (to prevent severe infections). Finally, once the patient is resuscitated and medically optimized, definitive therapy is achieved via emergent upper endoscopy for variceal band ligation.
Step-by-Step Solution
Key Concept
Acute management of life-threatening variceal bleeding requires strict adherence to the ABCs (Airway, Breathing, Circulation), prioritizing airway protection in patients with altered mental status or massive hematemesis prior to medical and endoscopic interventions.
