Update on the strategy for intravenous fluid treatment in acute pancreatitis

Table 1 Modified Marshall scoring system for organ dysfunction

	Scorea
Organ system	0	1	2	3	4
Respiration (PaO2/FiO2)b	> 400	301-400	201-300	101-200	< 101
Kidney (serum creatinine), µmol/L	< 134	134-169	170-310	311-439	> 439
Kidney (serum creatinine), mg/dL	< 1.4	1.4-1.8	1.9-3.6	3.7-4.9	> 4.9
Cardiovascular (systolic blood pressure), mmHg	> 90	< 90, fluid responsive	< 90, not fluid responsive	< 90, pH < 7.3	< 90, pH < 7.2

^aScore ≥ 2 for any system defines the presence of organ failure.

^bFor nonventilated patients, FiO₂ can be estimated by the rate of supplemental oxygen (Room air, 21%; 2 L/min, 25%; 4 L/min, 30%; 6-8 L/min, 40%; 9-10 L/min, 50%).

FiO₂: Fraction of inspired oxygen; PaO₂: Partial pressure of arterial oxygen.
