Abstract
What we know: In preschool children, small-volume spacers perform better than large-volume spacers. Detergent is the best antistatic agent for spacers, increasing lung delivery two- to threefold, but it must not be rinsed off. A mouthpiece should be used in children aged 2-3 years or older, as lung delivery is two- to threefold higher for oral inhalation than nasal inhalation (ie, by mask). Inhaled drug doses do not generally need to be reduced in infants and young children owing to inefficiencies of delivery in younger patients. Nebulisers are "dinosaurs" and not needed for most children with asthma. What we need to know: What is the best inhalation technique for spacers? How long should children breathe, how many breaths should they take, and at what age should they breath-hold? How should children, parents and doctors be instructed to achieve optimal levels of electrostatic charge reduction for spacers? How much should inhaled steroid dose be reduced when a spacer is used optimally? What dosing instructions should be given for beta(2)-agonists delivered by spacer?
