Aerosol Therapy and the Fighting Toddler: Is Administration During Sleep an Alternative?

Abstract: Insufficient cooperation during administration of aerosols by pressurized metered dose inhaler (pMDI)/spacers is a problem in nearly 50% of treated children younger than 2 years. For these children, administration during sleep might be more efficient. However, it is unknown how much aerosol reaches the lungs during sleep. The aim of this study was to determine in vitro the lung dose in young children from a pMDI/spacer during sleep and while being awake. Breathing patterns were recorded by a pneumotachograph i… Show more

“…Tidal volumes (TVs) were 50 mL, 100 mL, and 200 mL. These represented the range of TVs previously reported by Janssens and colleagues for infants who were 11 ± 5.1 months old and were breathing during sleep and while awake (Janssens et al 2003).…”

“…Tidal Volume Breathing: We chose tidal volumes and respiratory rate based on previously reported results by Janssens and colleagues (Janssens et al 2003). A computer-operated breathing simulator (PARI Breath Simulator, PARI GmbH, Starnberg, Germany) controlled respiratory rate at 15 breaths/30 s. The duration of inhalation was 0.9 s. The duration of exhalation was 1.1 s. The respiratory duty cycle (inspiratory time/total respiratory cycle time) was 0.45.…”

“…9 Aerosol-related factors include type of aerosol generator, patient interface, particle size, treatment time, mask dead volume, type of power gas, and type of solution. [10][11][12][13][14] Patient-related factors include differences in anatomy, breathing patterns, and behavioral challenges. [15][16][17][18] Higher tidal volumes (V T ) are associated with higher intrapulmonary deposition.…”

“…Это особенно важно при исполь зовании ДАИ/С, так как в этом случае плач может снизить депозицию препаратов примерно в 6 раз. В связи с этим обстоятельством высказывались предложения проводить ингаляции у детей младше го возраста во время сна [9]. Плач также влияет на ингаляции через небулайзер, однако в этом случае депозиция снижается существенно меньше -в 2,4 раза [10].…”
