Difficulty: MediumSurgical and Procedural Interventions

A 65-year-old man is brought to the emergency department by emergency medical services after vomiting bright red blood at home. He has a history of osteoarthritis for which he takes daily naproxen. Upon arrival, he appears pale, anxious, and diaphoretic. His temperature is 37.1°C (98.8°F), blood pressure is 92/58 mmHg, pulse is 118/min, and respiratory rate is 18/min. Physical examination reveals conjunctival pallor and mild epigastric tenderness. Digital rectal examination shows melena. Arrange the following procedural and management steps in the most appropriate chronological sequence for this patient.

  1. 1Establish dual large-bore peripheral intravenous access and begin crystalloid resuscitation
  2. 2Administer an intravenous proton pump inhibitor
  3. 3Perform esophagogastroduodenoscopy (EGD) for targeted hemostasis
  4. 4Proceed with transcatheter arterial embolization by interventional radiology

Answer

The correct sequence involves initial hemodynamic stabilization with intravenous fluids, followed by acid suppression therapy, primary endoscopic diagnosis and treatment, and finally angiographic rescue therapy if endoscopy fails.
The management of acute non-variceal upper gastrointestinal bleeding follows a strict stepwise algorithmic approach to maximize patient survival and procedural success. The immediate priority is addressing hypovolemic shock through robust intravenous access and fluid resuscitation. Once resuscitation is underway, profound acid suppression with an intravenous proton pump inhibitor is initiated to promote clot stability in the acidic gastric environment. Following initial stabilization, esophagogastroduodenoscopy is the primary procedural intervention for definitive diagnosis and targeted hemostasis (e.g., thermal coagulation, clipping). Finally, if endoscopic therapy fails to control the hemorrhage, transcatheter arterial embolization by interventional radiology serves as the definitive rescue intervention.

Step-by-Step Solution

1
Secure dual large-bore intravenous access and start intravenous fluids.
Hemodynamic stabilization and restoration of intravascular volume.
Addressing hemorrhagic shock is the immediate life-saving priority before any procedural intervention is considered.
2
Administer an intravenous proton pump inhibitor.
Elevation of gastric pH above 6.0.
A neutral pH stabilizes blood clots and prevents further degradation by pepsin, optimizing conditions prior to endoscopic visualization.
3
Perform esophagogastroduodenoscopy (EGD).
Direct visualization and targeted hemostasis of the bleeding source (e.g., peptic ulcer).
Endoscopy is the standard primary procedural modality for the diagnosis and control of upper gastrointestinal bleeding.
4
Consult interventional radiology for transcatheter arterial embolization.
Angiographic control of the bleeding vessel.
This is a salvage procedural intervention explicitly reserved for refractory bleeding that fails endoscopic control.
