Multicenter StudyMechanical ventilation in pediatric intensive care units during the season for acute lower respiratory infection: a multicenter study.
To describe the characteristics and outcomes of mechanical ventilation in pediatric intensive care units during the season of acute lower respiratory infections. ⋯ In the season of acute lower respiratory infections, one of every two children admitted to pediatric intensive care units requires mechanical ventilation. Acute respiratory failure was the most common reason for mechanical ventilation. The spontaneous breathing trial was the most commonly used method for liberation from mechanical ventilation.

Randomized Controlled TrialRandomized controlled trial of interrupted versus continuous sedative infusions in ventilated children.
To compare daily interruption vs. continuous sedative infusions in mechanically ventilated children with respect to lengths of mechanical ventilation and intensive care unit stay. ⋯ The length of mechanical ventilation, duration of intensive care unit stay, total dose of midazolam, and average calculated cost of the therapy were significantly reduced in the interrupted as compared to the continuous group of sedation.

The unique contribution of manual chest compression-vibrations to airflow during physiotherapy in sedated, fully ventilated children.
This study aimed to quantify the specific effects of manual lung inflations with chest compression-vibrations, commonly used to assist airway clearance in ventilated patients. The hypothesis was that force applied during the compressions made a significant additional contribution to increases in peak expiratory flow and expiratory to inspiratory flow ratio over and above that resulting from accompanying increases in inflation volume. ⋯ These results provide evidence of the unique contribution of compression forces in increasing peak expiratory flow and peak expiratory to inspiratory flow ratio bias over and above that related to accompanying changes from manual hyperinflations. Force generated during compression-vibrations was the single significant factor in multivariable analysis to explain the increases in expiratory flow bias. Such increases in the expiratory bias provide theoretically optimal physiological conditions for cephalad mucus movement in fully ventilated children.
