To describe the factors associated to morbidity-mortality in pediatric patients with severe head injury (SHI). ⋯ a) SHI in pediatric patients was associated with high morbidity-mortality; b) intracranial hypertension was associated to the development of serious sequelae; c) independent mortality risk factors were the existence of mydriasis, intracranial hypertension and hyperglycemia.

The clinical care of hospitalized seriously ill patients must be suitably proportionate independently of the functional unit to which they have been admitted. Most of these patients are admitted to the Intensive Care Unit (ICU), where uninterrupted management is provided, with important technological and care resources. However, hospitalization of the seriously ill patient must be understood as a continuum starting and ending beyond hospital stay. ⋯ In this context, our ICU has established two strategic lines. One consists of the identification of patients at risk outside the Unit and is based on the recognition, diagnostic orientation and early treatment of the seriously ill patient, in collaboration with other clinical specialties and independently of the hospital area to which the patient has been admitted. The second line in turn comprises clinical care within the actual Unit, and is based on the promotion of safety and the vigilance of nosocomial infections.

COPD and asthmatic patients use a substantial proportion of mechanical ventilation in the ICU, and their overall mortality with ventilatory support can be significant. From the pathophysiological standpoint, they have increased airway resistance, pulmonary hyperinflation, and high pulmonary dead space, leading to increased work of breathing. If ventilatory demand exceeds work output of the respiratory muscles, acute respiratory failure follows. ⋯ The physician must be cautious to avoid complications related to mechanical ventilation during ventilatory support. One major cause of the morbidity and mortality arising during mechanical ventilation in these patients is excessive dynamic pulmonary hyperinflation (DH) with intrinsic positive end-expiratory pressure (intrinsic PEEP or auto-PEEP). The purpose of this article is to provide a concise update of the most relevant aspects for the optimal ventilatory management in these patients.
