Children who are undergoing surgery need intravenous fluids to prevent dehydration and
maintain their electrolyte balance. The current standard of care in these children is to use
a fluid which is low in sodium (hypotonic fluid). The safety of this practice has never been
tested. There is ongoing concern from the medical community that this type of fluid
increases the child's risk of developing low sodium levels, and hence may not be safe for
all children. Low sodium can lead to significant complications such as seizures, coma and
even death, risks of which are often underestimated and not anticipated by their caregivers.
Experts in the field suggest that giving a solution with a similar sodium content to that of
blood (isotonic fluid) reduces the risk of these problems in these children. This study will
compare these two types of intravenous fluids (hypotonic versus isotonic), in a blinded
fashion (i.e. neither the patient nor caregivers or investigators will be aware which type
of fluid the patient is receiving), in children following surgery. The investigators goal is
to see which type of fluid is safer, and leads to more stable sodium levels. This would in
turn lead to a lower risk of complications as described above.
This is the first time such a study is preformed in pediatrics. There are unnecessary number
of complications and potential deaths from this disorder, and hence the safety of everyday
fluid practice in children needs to be scientifically tested. The results of this study will
enable the investigators to propose scientifically based guidelines on how to minimize risks
associated with intravenous infusions in children.

Inclusion Criteria: - Pediatric patients, 6 months corrected age -16 years, undergoing surgery. - Within 6 hours of the immediate post-operative period. - Post-operative stay anticipated to be more than 24 hours. - Primary route of fluid administration is anticipated to be intravenous, in the first 24 hours following surgery. - Informed consent of parent/guardian. - Consent to participate from surgeon. Exclusion Criteria: - Patients under 6 months of age - Patients equal to or over 17 years of age - Patients with hemodynamic instability , defined as a requirement for continuous vasoactive infusion (e.g. epinephrine, dopamine, norepinephrine, phenylephrine, milrinone, or Dobutamine) to maintain blood pressure at the end of surgery. - Patients admitted into the "short stay" post-operative unit - Patients in whom either hypotonic or isotonic solutions may be contraindicated/necessary: i.e. specific neurosurgical patients (ie those at risk of increased ICP, e.g. requiring actual brain surgery, ICP monitor or external ventricular drain insertion), patients with diabetic ketoacidosis, acute (= 7 days) burns, pre-existing CHF, liver failure or cirrhosis, renal failure. - Patients with known pre-existing risk of PNa derangements: DI or SIADH - Chronic diuretic use - defined as use of any oral or intravenous diuretics for = 7 days. - Known, uncorrected PNa derangement (PNa < 134 or > 146 mmol/L), identified peri-operatively (i.e. within 12 hours of surgery or during surgery). - Prior enrolment in this study - Patients or their guardians objecting to give consent. |
