An elderly patient with melena and hemodynamic instability. What is the initial step in management?

• A. Rapid IV fluid resuscitation and perform urgent endoscopy with resuscitation; transfuse as needed
• B. Start proton pump inhibitor infusion only
• C. Observe and recheck
• D. Immediate surgery

Answer: (A)

The main idea is that an unstable patient with an upper GI bleed needs immediate circulation support and then definitive control of the bleeding source. Start with rapid resuscitation using isotonic crystalloids and two large-bore IV lines, and obtain crossmatched blood for transfusion as indicated by ongoing bleeding and hemodynamics. While resuscitating, monitor vitals, urine output, and labs, and prepare for urgent endoscopy.

Once the patient is stabilized, perform urgent esophagogastroduodenoscopy to locate and treat the source of bleeding. Endoscopy serves both diagnostic and therapeutic roles and can promptly reduce mortality by applying hemostatic measures or performing interventions tailored to the source (for example, clipping, cautery, or injection for ulcers; banding or sclerotherapy for variceal bleeds).

Starting a proton pump inhibitor infusion alone does not rapidly control active bleeding in a hemodynamically unstable patient, and simply observing would miss ongoing hemorrhage. Immediate surgery is reserved for cases where endoscopic therapy fails or is not feasible, or in patients with uncontrolled bleeding despite resuscitation and endoscopic attempts. The priority is to stabilize the patient first, then rapidly identify and control the bleed endoscopically.
