Nebulized Corticosteroids for Pediatric Cough and Wheezing
Nebulized corticosteroids, such as budesonide, beclomethasone, and flunisolide, are commonly used in pediatric patients with cough associated with asthma or wheezing episodes. Studies show that nebulized budesonide inhalation suspension (BIS) improves cough and other symptoms in children with cough variant asthma, with individualized treatment duration based on symptom severity. Children with mild symptoms improve faster, while those with severe symptoms may need longer treatment. Importantly, no severe or drug-related adverse events were reported with this therapy . Similarly, a one-week course of nebulized beclomethasone, combined with as-needed salbutamol, increased symptom-free days and reduced cough scores in preschool children with wheezing, supporting the short-term use of inhaled corticosteroids for episodic wheeze and cough . Nebulized flunisolide has also been shown to significantly improve cough and wheezing in infants and young children with asthma, with no reported side effects .
Nebulized Hypertonic Saline for Viral Bronchiolitis and Cough
For infants hospitalized with moderate to severe viral bronchiolitis, nebulized 3% hypertonic saline (HS) has been found to relieve cough and wheezing more quickly than normal saline. The time to cough remission and overall hospital stay were both significantly reduced in the HS group, and the treatment was well tolerated without apparent adverse effects .
Nebulized Interferon and Ambroxol for Pediatric Respiratory Diseases
Nebulized interferon alpha-1b (IFN-α1b) has demonstrated effectiveness in alleviating cough and wheezing in infants with bronchiolitis, with significant improvements in cough severity and duration compared to control groups . Additionally, nebulized ambroxol hydrochloride has shown better efficacy than intravenous administration in improving cough and other respiratory symptoms in children, with faster symptom resolution, shorter hospital stays, and fewer side effects .
Nebulized Medications for Cough Suppression During Procedures
In the context of pediatric procedures such as flexible fiberoptic bronchoscopy, nebulized dexmedetomidine and ketamine have both been shown to reduce the incidence of moderate to severe cough more effectively than topical lidocaine, with no significant difference between the two nebulized agents . There is also a case report of an adolescent with severe COVID-19 cough who experienced improvement with nebulized lidocaine, which was well tolerated and associated with decreased sedation needs .
Considerations for Nebulizer Use and Alternatives
While nebulizer treatments are effective for pediatric cough and wheezing, there are infection control concerns, especially during the COVID-19 pandemic. Nebulizers can generate aerosols that may increase the risk of viral transmission. Pressurized metered dose inhalers (pMDIs) with spacers or valved-holding chambers (VHCs) are recommended as equally effective alternatives for most children, reducing infection risk and side effects. Nebulization should be reserved for severe cases or when pMDI/VHC is not feasible .
Conclusion
Nebulized therapies, including corticosteroids, hypertonic saline, interferon, ambroxol, and certain sedative agents, are effective in managing cough and related symptoms in pediatric respiratory diseases. Treatment choice and duration should be tailored to the severity and underlying cause of the cough. In the context of infectious disease outbreaks, alternatives to nebulization should be considered to minimize infection risk, reserving nebulizer use for specific clinical situations.
