Background:
We aimed to compare outcomes according to a Lactated Ringers (LR) versus Normal Saline (NS)-based strategy for acute pancreatitis.
Methods:
A database search through November 2020 was done to identify studies comparing LR to NS for fluid rehydration in AP. The primary endpoint was systemic inflammatory response syndrome (SIRS) at 24 h. Mantel-Haenszel pooled odds ratios (OR) and 95% confidence intervals were constructed using a random effects model. Heterogeneity was assessed using the I2 statistic. Publication bias was assessed using funnel plots.
Results:
Six studies were included totaling 549 patients. No difference in the odds of developing SIRS was noted at 24 h (pooled OR 0.59, 95% CI 0.22-1.62, P = 0.31) between LR and NS. I2 indices showed low heterogeneity between the groups, and a funnel plot showed no obvious publication bias. There was no difference between LR and NS found for SIRS at 48 and 72 h, mortality, and other secondary outcomes. LR was associated with a decreased need for ICU admission.
Conclusions:
This updated meta-analysis does not support the previously published finding that the use of LR (rather than NS) leads to a statistically significant decreased odds of SIRS in acute pancreatitis.
