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.

In general pediatric surgical patients, do isotonic PMS compared to hypotonic PMS, result in a lower risk of acute hospital acquired plasma sodium derangements, occurring at any time during the study intervention? Primary efficacy objective -To determine the impact of postoperative administration of isotonic compared to hypotonic PMS on the risk of hospital acquired PNa derangements in pediatric surgical patients, occurring at any time during the study intervention.
Secondary efficacy objectives: a) To determine the impact of postoperative administration of isotonic compared to hypotonic PMS on clinical sequelae related to acute PNa changes, in pediatric surgical patients. b) the independent predictors of hospital acquired PNa derangements will be explored.
This is a double-blind randomized controlled trial. Participants, health care providers, data collectors, and judicial assessors of outcomes will be blinded to the study intervention.
Setting: McMaster Children's Hospital.
Enrolled patients will be randomized postoperatively to receive either one of the following parenteral maintenance solutions: 1) hypotonic PMS, or 2) isotonic PMS. For the purposes of this study the hypotonic PMS will be 0.45%NaCl, and the Isotonic PMS will be 0.9% NaCl. Enrolled patients will receive their allocated treatment (provided there are no safety issues or concerns) until they are fully orally fed and the PMS rate is no greater than a rate required to "keep vein open (KVO)", to a maximum duration of 48 hours. The physician can thereafter administer the maintenance solution of their choice. The following parameters will be monitored in each study participant during the treatment period: hourly urine output, strict intake and output, 12 hourly fluid balances and daily weights. Blood and urine samples will be obtained on study patients every 12 hours until they are fully orally fed and the IV rate is at KVO, for a maximum of 48 hours. Any additional investigations ordered by the caring physician during the treatment and follow up period will also be recorded. Patients will be followed for clinical outcomes for 48 hours after the study intervention is discontinued, or until the time of discharge.
