Fluid management of children during neurosurgery is not well established. Hypotonic solutions, commonly still used in pediatric patients, may enhance cerebral edema and worse operative conditions. This study compares two different isotonic solutions administered perioperatively regarding acid base and fluid electrolyte disturbances.

| serum chloride difference (mmol/L) | Serum chloride will be collected in two different moments: right before the beginning of the surgery and right after de end of the procedure. We will calculate the difference between the two values. | from the admission of the patient in the operating room until the end of the surgery. |
| Measure | Description | Time Frame |
|---|---|---|
| serum chloride difference (mmol/L) | Serum chloride will be collected right after the end of the surgery as well as 24 hours after the admission in ICU. We will calculate the difference between the two values. | from the end of the surgery until exactly 24 hours after the admission in intensive care unit (ICU) |
