Comparative Study
Barotrauma not related to type of positive pressure ventilation during severe asthma exacerbations in children.
Children with impending respiratory failure due to severe asthma may be treated with endotracheal intubation and mechanical ventilation. Barotrauma occurs in a significant number of these children. Non-invasive positive pressure ventilation (NPPV) has been used as an alternative intermediary therapy and potentially prevents intubation. However, the comparative risk of barotrauma associated with the use of NPPV has not been evaluated in this population. ⋯ The use of positive pressure is associated with an increased risk of barotrauma in children with asthma, regardless of the mode of delivery.

This study evaluated the sleep/wake cycle of individuals with asthma in relation to asthma control, daytime sleepiness, and daytime activity. Ten persons with mild to moderate persistent asthma monitored their sleep quality and daytime wakefulness for 7 consecutive days using 24-hours wrist actigraphy. Degree of asthma control strongly correlated with sleep quality. ⋯ Poor asthma control, use of rescue medications, and asthma symptoms were associated with daytime sleepiness and limitations in physical activity and emotional function. Forty percent of subjects reported clinically significant daytime sleepiness. Evaluating asthma throughout a 24-hour cycle provides valuable information on variations in the sleep/wake cycle associated with asthma control, use of rescue medications, and asthma symptoms.
