Mesh nebulizers enabling transnasal pulmonary delivery of medical aerosols to infants and toddlers: Roles, challenges, and opportunities
The development of mesh nebulizer technology has expanded the ability to deliver medical aerosols to infants and small children via nasal cannula and prongs. Mesh nebulizers do not require compressed gas to generate aerosols and have a smaller, lighter profile facilitating placement in delivery circuits, unlike ultrasonic nebulizers. Prior to this century, aerosol delivery with the nasal interface to 1–4 kg infants or surrogate animal models was limited to low single-digit deposition. In vitro and animal studies with the enabling mesh technology increase inhaled dose by upwards of 14% when nasal continuous positive airway pressure ventilation is in use. Recently, investigations of transnasal aerosol delivery to the lung have expanded to include nasal cannula interfaces with both high and low flow oxygen administration, nasal continuous positive airway pressure therapy, and nasal noninvasive ventilation in treating respiratory distress, respiratory insufficiency, and acute respiratory failure of infants and toddlers. We will first examine the progression of testing transpulmonary delivery of medical aerosols from in vitro models to in vivo animal and human studies. Then, we will explain current and developing applications in clinical practice to view future directions and opportunities.
