Primary Institution: Montreal Children's Hospital, McGill University

Hypothesis

Serum sodium would fall among children receiving 0.45% saline and remain stable or increase among children receiving isotonic fluids.

Conclusion

0.45% saline did not result in a drop in serum sodium during the first 12 hours of fluid therapy in children without severe baseline hyponatremia.

Supporting Evidence

  • The rate of change in serum sodium was significantly different from zero only for the 0.9% saline group.
  • Most children receiving 0.45% saline did not experience a drop in sodium levels.
  • The study included both medical and surgical patients, providing a diverse population.

Takeaway

This study looked at two types of IV fluids for kids in the hospital. It found that one type didn't lower sodium levels, which is good.

Methodology

This was a masked controlled trial with randomization stratified by admission type, comparing 0.45% and 0.9% saline in 5% dextrose.

Potential Biases

Exclusion of children with baseline sodium levels outside the normal range may have biased results.

Limitations

The study had a small sample size and a high dropout rate, which may limit the generalizability of the findings.

Participant Demographics

Children aged 3 months to 18 years, including medical and surgical patients.
