Comparison of early aggressive versus nonaggressive fluid resuscitation in acute pancreatitis: a meta-analysis

ABSTRACT:

Background:

Early fluid resuscitation is one of the main therapeutic strategies for acute pancreatitis (AP). This study investigated the effects of early aggressive and nonaggressive hydration on AP.

Objectives:

The aim of this meta-analysis is to investigate the differences between aggressive and nonaggressive intravenous fluid resuscitation in AP.

Design:

This study was based on publicly available data, all of which have been extracted from previous ethically approved studies.

Data sources and methods:

Two authors systematically searched PubMed, Embase (via OVID), Web of Science, and Cochrane Library to find all published research before February 2023. In-hospital mortality were set as primary endpoints.

Results:

This meta-analysis included seven randomized controlled trials (RCTs) and eight cohort studies with 4072 individuals in nonaggressive (n = 2419) and aggressive (n = 1653) hydration groups. The results showed that patients in the nonaggressive group had a lower mortality rate than those in the aggressive hydration group [relative risks (RR), 0.66; p = 0.02]. Subgroup analysis results showed that patients in the nonaggressive hydration group had lower mortality rates in RCTs (RR, 0.39; p = 0.001), studies conducted in Eastern countries (RR, 0.63; p = 0.002), and studies with severe pancreatitis (RR, 0.65; p = 0.02). In addition, the nonaggressive hydration group had lower rates of infection (RR, 0.62; p < 0.001), organ failure (RR, 0.65; p = 0.02), and shock (RR, 0.21; p = 0.02), as well as a shorter hospital stay (weighted mean difference, −1.63; p = 0.001) than the aggressive hydration group.

Conclusions:

Early nonaggressive fluid resuscitation is associated with lower mortality, lower risk of organ failure and infection, and shorter hospital stays than aggressive fluid resuscitation.

Project description:BackgroundCurrent practice guidelines for optimal infusion rates during early intravenous hydration in patients with acute pancreatitis (AP) remain inconsistent. This systematic review and meta-analysis aimed to compare treatment outcomes between aggressive and non-aggressive intravenous hydration in severe and non-severe AP.MethodsThis study followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. We systematically searched PubMed, Embase and Cochrane Library for randomized controlled trials (RCTs) on November 23, 2022, and hand-searched the reference lists of included RCTs, relevant review articles and clinical guidelines. We included RCTs that compared clinical outcomes from aggressive and non-aggressive intravenous hydration in AP. Meta-analysis was performed using a random-effects model for participants with severe AP and non-severe AP. Our primary outcome was all-cause mortality, and several secondary outcomes included fluid-related complications, clinical improvement and APACHE II scores within 48 h.ResultsWe included a total of 9 RCTs with 953 participants. The meta-analysis indicated that, compared to non-aggressive intravenous hydration, aggressive intravenous hydration significantly increased mortality risk in severe AP (pooled RR: 2.45, 95% CI: 1.37, 4.40), while the result in non-severe AP was inconclusive (pooled RR: 2.26, 95% CI: 0.54, 9.44). However, aggressive intravenous hydration significantly increased fluid-related complication risk in both severe (pooled RR: 2.22, 95% CI 1.36, 3.63) and non-severe AP (pooled RR: 3.25, 95% CI: 1.53, 6.93). The meta-analysis indicated worse APACHE II scores (pooled mean difference: 3.31, 95% CI: 1.79, 4.84) in severe AP, and no increased likelihood of clinical improvement (pooled RR:1.20, 95% CI: 0.63, 2.29) in non-severe AP. Sensitivity analyses including only RCTs with goal-directed fluid therapy after initial fluid resuscitation therapy yielded consistent results.ConclusionsAggressive intravenous hydration increased the mortality risk in severe AP, and fluid-related complication risk in both severe and non-severe AP. More conservative intravenous fluid resuscitation protocols for AP are suggested.
