BACKGROUND: Fluid resuscitation is one of the main therapies for acute pancreatitis (AP). There is still no consensus on the type of fluid resuscitation. This study investigated the differences between lactate Ringer's (LR) and normal saline (NS) in treating AP.

METHODS: Two authors systematically searched Web of Science, Embase (via OVID), Cochrane Library, and PubMed to find all published research before July, 2023. The odds of moderately severe/severe AP and intensive care unit (ICU) admission are set as primary endpoints.

RESULTS: This meta-analysis included 5 RCTs and 4 observational studies with 1424 AP patients in LR (n = 651) and NS (n = 773) groups. The results suggested that the odds of moderately severe/severe AP (OR 0.48; 95%Cl 0.34 to 0.67; P < 0.001) and ICU admission (OR 0.37; 95%Cl 0.16 to 0.87; P = 0.02) were lower in the LR group compared to NS group. In addition, the LR group had lower rates of local complications (OR 0.54; 95%Cl 0.32 to 0.92; P = 0.02), lower level of CRP, as well as a shorter hospital stay (WMD, - 1.09 days; 95%Cl - 1.72 to - 0.47 days; P < 0.001) than the NS group. Other outcomes, such as mortality, the rate of organ failure, SIRS, acute fluid collection, pancreatic necrosis, pseudocysts, and volume overload, did not differ significantly between two groups (P > 0.05).

CONCLUSIONS: LR is preferred over NS as it decreases the odds of moderately severe/severe AP, the rate of ICU admission, local complication, and length of hospital stay. However, large-scale RCT are lacking to support these evidence.
