An ambulance brings a 55-year-old man to the emergency department after he vomited a large volume of bright red blood at his home. The paramedics report that the patient felt dizzy and nearly fainted when they attempted to sit him up. On arrival, he appears pale, diaphoretic, and lethargic. His temperature is (), blood pressure is , pulse is , and respiratory rate is . Pulse oximetry shows on room air. He groans in response to pain but does not answer questions coherently. Which of the following is the most appropriate initial step in the management of this patient?
- Establish two large-bore intravenous lines and initiate fluid resuscitationAnswer
- BPerform an emergent esophagogastroduodenoscopy
- COrder a computed tomography angiography of the abdomen
- DTransfer the patient immediately to the intensive care unit
- EAdminister intravenous propranolol to reduce portal venous pressure
Answer
Establish two large-bore intravenous lines and initiate fluid resuscitation
This patient is presenting with a massive upper gastrointestinal hemorrhage leading to hypovolemic (hemorrhagic) shock, as evidenced by his profound hypotension, marked tachycardia, pallor, diaphoresis, and lethargy. In the algorithmic approach to critically ill patients, initial stabilization follows the ABCs (Airway, Breathing, Circulation). While his altered mental status requires close monitoring of his airway, his most immediate, rapidly reversible life threat is cardiovascular collapse from volume loss. The most appropriate initial step is to establish two large-bore intravenous lines (18-gauge or larger) to allow for the rapid, high-volume infusion of isotonic crystalloids and, subsequently, matched or uncrossmatched blood products.
Step-by-Step Solution
Key Concept
In patients presenting with acute hemorrhagic shock, immediate hemodynamic stabilization via large-bore intravenous access and fluid resuscitation is the absolute first step, preceding all diagnostic studies and definitive interventions.
