A 67-year-old man on day 6 of mechanical ventilation for severe pneumonia and septic shock develops hemodynamic instability (MAP 58 mmHg on noradrenaline 0.4 µg/kg/min), a drop in hemoglobin from 11.2 to 7.8 g/dL, and black nasogastric aspirate. Laboratory studies show INR 1.6 and platelets 78/μL. Stress ulcer prophylaxis had been discontinued on day 3. Urgent upper endoscopy reveals multiple shallow erosions and two larger ulcers with Forrest IIa (visible vessel) and Forrest Ib (oozing) lesions in the gastric body and fundus, consistent with stress-related mucosal disease. Which of the following management approaches marked as **A** in the diagram best addresses the acute bleeding and underlying pathophysiology in this critically ill patient?
A. Immediate surgical gastrectomy
B. Discontinue PPI prophylaxis going forward
C. IV PPI infusion, urgent endoscopy with hemostasis, and ICU resuscitation
D. Outpatient oral pantoprazole for 4 weeks
Explanation
Why IV PPI infusion, urgent endoscopy with hemostasis, and ICU resuscitation is right
Stress-related mucosal disease in critically ill patients arises from splanchnic hypoperfusion, mucosal ischemia, and acid back-diffusion. The validated management approach (Krag et al. SUP-ICU trial NEJM 2018; ASGE Guidelines 2020; Surviving Sepsis Campaign 2021) requires a three-pronged strategy: (1) ICU resuscitation with balanced crystalloid and reversal of coagulopathy (vitamin K, FFP, platelets) to restore perfusion and hemostasis; (2) high-dose IV PPI (pantoprazole 80 mg bolus then 8 mg/h infusion for 72 hours) to suppress gastric acid and prevent back-diffusion; and (3) urgent upper endoscopy within 12–24 hours with endoscopic hemostasis using dual therapy (epinephrine injection plus clipping or thermal coagulation) for Forrest IIa and Ib lesions. This patient has active bleeding with hemodynamic instability and coagulopathy—all indications for immediate combined medical and endoscopic intervention. The anchor letter A encapsulates the evidence-based standard of care.
Why each distractor is wrong
Outpatient oral pantoprazole for 4 weeks: This is grossly inadequate for acute hemorrhage with hemodynamic instability. Oral medication cannot be given to a ventilated, hemodynamically unstable patient; high-dose IV PPI is required. Outpatient management is appropriate only for stable, non-bleeding patients in the community, not for ICU stress bleeding.
Immediate surgical gastrectomy: Surgery is a last-resort option only after failed endoscopic therapy and interventional radiology. Current guidelines (ASGE 2020) prioritize endoscopic hemostasis as first-line definitive treatment. Surgical gastrectomy carries high morbidity and mortality in a septic, coagulopathic patient and is not indicated as initial management.
Discontinue PPI prophylaxis going forward: This is dangerous and contradicts evidence. This patient has multiple validated risk factors for stress ulceration (mechanical ventilation >48 hours, coagulopathy, sepsis with shock). Prophylaxis should be continued or re-initiated in high-risk ICU patients to prevent recurrent bleeding. Discontinuation would increase re-bleeding risk.
High-YieldNEET PG
Stress ulcer bleeding in ICU requires triple therapy: resuscitate (correct coagulopathy), high-dose IV PPI (suppress acid), and urgent endoscopic hemostasis (dual therapy for visible vessels and oozing). Surgery is only after failed endoscopy and IR.
