Choice of maintenance intravenous fluids among paediatric residents in Canada

ABSTRACT: Abstract

Background

Recent literature and guidelines support routine use of isotonic intravenous (IV) fluids for maintenance therapy in hospitalized infants and children. Current prescribing practices are unknown.

Objective

To elicit paediatric residents’ choice of maintenance IV fluids, particularly with regard to tonicity, in a variety of clinical scenarios and patient ages. We hypothesized that residents would choose isotonic fluids in most cases, but there would be substantially more variability in fluid choice in the neonatal age group.

Methods

An Internet-based survey was e-mailed to trainees in the 17 paediatric residency programs across Canada, via the Canadian Paediatric Program Directors. The survey instrument included questions related to training, followed by a series of questions eliciting choice of IV fluid in a variety of clinical situations.

Results

A total of 147 survey responses were submitted (22% response rate). Isotonic solutions were selected by >75% across all clinical scenarios involving infants and children. Very hypotonic fluids were seldom chosen. There was more variability in fluid choice in neonates, with evidence of significant differences in fluid tonicity based on senior versus junior resident status and geographical location.

Conclusions

Results imply a predominance of isotonic fluid use in infants and children, suggesting that clinical practice has changed in response to risk of hyponatremia with hypotonic IV fluids. As hypothesized, there was more variability with respect to choice of maintenance fluids in neonates. This likely reflects a paucity of guidance in an age group with unique physiologic factors affecting fluid and electrolyte status.

Project description:Hyponatraemia is a known complication in hospitalised children receiving maintenance intravenous fluid. Several studies have been published to investigate the efficacy and safety of intravenous fluids in children. However, there is still an ongoing debate regarding the ideal solution to be used in the paediatric population. Therefore, the aim of this meta-analysis was to investigate the safety and efficacy of administering isotonic versus hypotonic intravenous maintenance fluid in hospitalised children. An extensive search was undertaken on PubMed, Web of Science, Scopus, ScienceDirect, Google Scholar and Cochrane Library on 28 December 2020. Only randomised controlled trials (RCTs) were included. We used the random-effects model for all analyses. Risk ratio (RR) and mean difference with 95% confidence intervals (CIs) were used for dichotomous and continuous outcomes, respectively. The quality of each study was assessed using the Joanna Briggs Institute critical appraisal tool for RCTs. This study is registered with PROSPERO (CRD42021229067). Twenty-two RCTs with a total of 3795 participants were included. The studies encompassed surgical and medical patients admitted to intensive care unit as well as to general wards. We found that hypotonic fluid significantly increases the risk of hyponatremia at both ≤24 h (RR 0.34; 95% CI: 0.26-0.43, p < 0.00001) and >24 h (RR 0.48; 95% CI: 0.36-0.64, p < 0.00001). Isotonic fluid increases the risk of hypernatraemia at ≤24 h (RR 2.15; 95% CI: 1.24-3.73, p = 0.006). The prevalence of hyponatraemia was also higher in the hypotonic group at both ≤24 h (5.7% vs. 23.3%) and >24 h (6.0% vs. 26.3%). There was no statistically significant difference in the risk of developing adverse outcomes between the two groups. Mean serum and urine sodium as well as serum osmolality/osmolarity was lower in the hypotonic group. Isotonic solution is protective against the development of hyponatraemia while hypotonic solution increases the risk of hyponatraemia.
