A 52-year-old male presents with severe, constant epigastric pain that radiates directly through to his back, accompanied by persistent vomiting. Serum lipase is 1250 U/L (reference < 60 U/L). Abdominal CT confirms interstitial edematous acute pancreatitis without necrosis. What is the cornerstone of early management during the first 24 to 48 hours?

Answer and explanation

Correct answer: C. Goal-directed IV fluid hydration and multimodal analgesia

  1. Step 1: According to international guidelines (IAP/APA and ACG), acute pancreatitis diagnosis requires >= 2 of 3 features: characteristic abdominal pain, serum lipase/amylase > 3x upper limit of normal, and characteristic cross-sectional imaging findings.
  2. Step 2: The cornerstone of early treatment is goal-directed intravenous hydration with isotonic crystalloids (Lactated Ringer's preferred over normal saline) at 200-500 mL/hr to maintain microvascular pancreatic perfusion and prevent necrotizing progression.
  3. Step 3: Routine prophylactic antibiotics are NOT recommended for sterile acute pancreatitis.
Answer
Goal-directed IV fluid hydration and multimodal analgesia.
Why not the others: 'Prophylactic carbapenem antibiotics' have been shown in multiple clinical trials to provide no benefit in sterile acute pancreatitis and promote fungal resistance; 'Immediate surgical debridement' is contraindicated in early pancreatitis; 'Strict starvation and TPN' is outdated; early oral feeding as tolerated is standard.
