Abstract

Objective

Fluid resuscitation is an important intervention in children with septic shock. The composition of resuscitation fluid is a matter of debate. Our aim was to study the effects of balanced salt solution (BSS) versus normal saline (NS) for resuscitation in pediatric septic shock.

Data sources

We searched MEDLINE, Embase, LILAC, Cochrane Collaboration, ClinicalTrials.gov, and World Health Organization International Clinical Trials Registry Platform.

Study selection

Two independent authors screened title and abstracts and then full papers of included studies.

Data extraction

Two authors extracted data from full papers independently. Random-effects model was used for analysis of RCTs. We used Cochrane's risk of bias tool for assessing the quality of studies. Primary outcome was mortality and secondary outcomes were rates of acute kidney injury (AKI), need for renal replacement therapy (RRT), and adverse effects (hyperchloremia, metabolic acidosis, and fluid overload); and duration of PICU and hospital stay.

Data synthesis

Five RCTs with 992 children were included. Resuscitation with BSS versus NS was not associated with reduction in mortality (RR 0.82, 95% CI 0.45-1.50, p = 0.52; RCTs = 5); with similar results on sensitivity analysis (RR 0.76, 95% CI 0.41-1.41, p = 0.52; 4 RCTs = 4). However, resuscitation with BSS was associated with lower rates of AKI (sensitivity analysis RR 0.64, 95% CI 0.50-0.82, p = 0.0004; RCTs = 3); lesser need for RRT (RR 0.52, 95% CI 0.35-0.76, p = 0.0008; RCTs = 2); and lower rate of hyperchloremia (RR 0.74, 95% CI 0.62-0.87, p = 0.0002; RCTs = 3). The data is scant for other secondary outcomes (metabolic acidosis, fluid overload, and duration of PICU and hospital stay) to make any suggestions. The overall ‘risk of bias’ was low and unclear in most domains.

Conclusion

Use of BSS as resuscitation fluid in pediatric septic shock was not associated with reduction in mortality. However, BSS was associated with decreased risk of AKI, need of RRT and hyperchloremia.
