To assess the use of noninvasive ventilation (NIV) in children and its application in the acute and chronic setting of pediatric respiratory failure. ⋯ Although the use of NIV is increasingly recognized in pediatrics, there are currently still no generally accepted guidelines for its use. In the chronic setting, its use has mainly been proven in obstructive sleep apnea and respiratory failure secondary to neuromuscular disorders. It would appear that the major challenge is ensuring compliance, and this can be enforced by patient/caregiver education, use of a suitable interface, heated humidifiers and by minimizing the side effects of NIV. In the setting of acute respiratory failure, it would appear from available data that success is usually predicted by the rapidity of response. Patients placed on NIV should be monitored closely and this mode of ventilation should be reviewed if there is a lack of response within a few hours after commencement of therapy.

To examine electrolyte-free water requirements that should be considered when administering maintenance fluids in a critically ill child. We examine some of the difficulties in estimating these requirements, and discuss the controversies with respect to the traditional recommendations. ⋯ Maintenance fluid prescriptions should be individualized. No single intravenous solution is ideal for every child during all phases of illness, but there is evidence to suggest that the safest empirical choice is an isotonic solution. Hypotonic solutions should only be considered if the goal is to achieve a positive free-water balance. Critically ill children may require a reduction by as much as 40-50% of the currently recommended maintenance volumes. All patients receiving intravenous fluids should be monitored closely with daily weights, fluid balances, biochemical and clinical parameters in order to best guide this therapy.

Coagulation disorder in children and adolescents with moderate to severe traumatic brain injury.
To describe the epidemiological profile of children and adolescents with moderate to severe traumatic brain injury admitted to an intensive care unit; to describe the frequency of coagulation disorders in these patients; to determine the relationship between coagulopathy and trauma severity; to assess the factors associated with coagulopathy; and to assess the effect of coagulopathy on the mortality of these patients. ⋯ The development of coagulopathy is a frequent complication in patients with moderate to severe traumatic brain injury. Even though it is not closely associated with death in this study, it may be regarded as a marker of injury severity.
