A 38-year-old man with a 10-year history of alcohol abuse presents to the emergency department with severe epigastric pain radiating to the back, nausea, and vomiting for 6 hours. Vital signs show BP 110/70 mmHg, HR 102/min, RR 20/min, temperature 37.8°C. On examination, he has epigastric tenderness with guarding. Serum lipase is 1200 U/L (normal <100), amylase 950 U/L. Abdominal ultrasound shows pancreatic edema with no gallstones. What is the most appropriate immediate next step in management?

Explanation

## Immediate Management of Acute Pancreatitis **Key Point:** The cornerstone of early acute pancreatitis management is aggressive fluid resuscitation to restore intravascular volume, prevent organ dysfunction, and reduce mortality. This takes absolute priority in the first 24–48 hours. ### Rationale for Correct Answer This patient has mild-to-moderate acute pancreatitis (Ranson score likely 2–3 based on age, WBC, glucose, LDH not mentioned but lipase elevation). The **immediate priority** is: 1. **NPO status** — allows pancreatic rest 2. **Aggressive IV fluid resuscitation** — 250–500 mL/hour of normal saline (or Ringer's lactate) to: - Restore circulating volume - Prevent acute kidney injury - Reduce pancreatic microvascular thrombosis - Lower mortality in severe pancreatitis **High-Yield:** Early goal-directed fluid therapy (target urine output 0.5–1 mL/kg/hour, CVP 8–12 mmHg if available) within the first 24–48 hours is the single most evidence-based intervention in acute pancreatitis [cite:Harrison 21e Ch 346]. ### Why Other Steps Are Premature | Step | Timing | Rationale | |------|--------|----------| | ERCP + sphincterotomy | Only if biliary obstruction/cholangitis proven | No indication here; ultrasound shows no stones; patient is stable | | Empiric antibiotics | Reserved for infected necrosis (day 7–10) or sepsis | Prophylactic antibiotics do NOT improve outcomes in sterile pancreatitis | | CT abdomen | After 48–72 hours if clinical deterioration | Premature imaging delays fluid resuscitation; CT is for risk stratification and necrosis assessment, not immediate diagnosis | **Clinical Pearl:** Fluid resuscitation should begin **within 1 hour** of diagnosis. Delayed or inadequate fluid therapy is associated with organ failure and increased mortality. **Mnemonic: PANC-REST** — Pancreatic rest (NPO), Aggressive fluids, No antibiotics (unless infected), Correct electrolytes, Resuscitate early, Supportive care, Treat underlying cause.
