Variation in Natremia Using Two Different Maintenance Intravenous Fluids in Postsurgical Hospitalized Children (surgical-Na)
Hyponatremia
About this trial
This is an interventional treatment trial for Hyponatremia focused on measuring Hyponatremia, Water-Electrolyte Imbalance
Eligibility Criteria
Inclusion Criteria:
- Postsurgical children admitted to HGNPE Department of Surgery between january 2010 and october 2011.
Aged 1 month to 16 years. Initial plasma Na between 135-145 mmol/L. Primary route of fluid administration is anticipated to be intravenous, in the first 12 hours following surgery.
Informed consent of parent/guardian.
Exclusion Criteria:
• Children with illness that have primary fluid and electrolyte imbalance such as:
- Shock: Defined as acute circulatory failure resulting in decreased tissue perfusion and manifesting as altered sensorium, hypothermia (<35oC), tachycardia, prolonged capillary filling time (>3 seconds), hypotension (BP < 5th percentile for age), oliguria (<0.5 ml/kg/hr), hypoxemia, hyperlactatemia, requirement of fluid bolus and/ or vasopressors.
- Diarrhea and Dehydration: Children presenting with diarrhea and features of dehydration: lethargy, irritability and altered sensorium, thirst, decreased urine output, sunken eyes & dry mucous membranes, loss of skin elasticity.; children with ongoing diarrhea will be excluded even if there is no dehydration.
Fluid Overload: Cirrhosis, Congestive heart failure, Acute and Chronic renal failure, Nephrotic syndrome.
- Hyperglycemia: blood glucose > 180 mg/ dl.
- Require ICU admission.
- Severe Protein Energy Malnutrition: Defined as grade III (50-59% of expected weight for age) and grade IV (less than 50% of expected weight for age) as per IAP classification.
- 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
