For decades, acute pancreatitis meant wide-open crystalloid. The first adequately designed trial of the question stopped early because aggressive fluid caused harm and prevented nothing.

Adjusted RR 2.85 (95% CI 1.36–5.94). The reason the trial stopped.

01
The trial
Design
Open-label RCT, 18 centers, 4 countries
Population
Adults with acute pancreatitis, no organ failure at enrollment
Fluid
Lactated Ringer's in both arms
Stopped
First interim analysis, 249 of 744 planned, for safety
Every patient was reassessed at 12, 24, 48, and 72 hours, and fluid was adjusted by protocol in both arms. Median hospital stay was 6 days with aggressive fluid and 5 with moderate.
02
The two regimens
Aggressive
Moderate
Bolus
20 mL/kg over 2 hours
10 mL/kg only if hypovolemic; none if normovolemic
Infusion
3 mL/kg/h
1.5 mL/kg/h
For a 70 kg adult
1.4 L bolus, then 210 mL/h
0 or 700 mL bolus, then 105 mL/h
03
What it supports
Aggressive early fluid causes fluid overload in pancreatitis without preventing severe disease.
Moderate, goal-directed lactated Ringer's is the safer default; ACG 2024 now recommends moderate fluid.
It did not test patients already in shock or organ failure; they were excluded and need resuscitation to their physiology.
Stopping early means the benefit question was never fully answered, but the harm signal was clear enough to stop.
Open-label, so fluid-overload ascertainment could carry some bias.
04
At the bedside
Moderate, then reassess. Lactated Ringer's at about 1.5 mL/kg/h, a 10 mL/kg bolus only if the patient is hypovolemic, and scheduled reassessment of volume status, urine output, and BUN. Escalate for hypovolemia, not by default.
Pairs with pancreatitis-severity-ranson-bisap: early scores identify who needs watching, and they are not a reason to give more fluid.
