Dexamethasone in laryngeal diphtheritic croup
1Department of Paediatrics, JN Medical College, Belgaum, Karnataka, India.
Insights
Intravenous dexamethasone, alongside antibiotics and antitoxin, effectively reduced airway obstruction in children with laryngeal diphtheria. This treatment potentially helps avoid tracheostomy in many cases of this serious respiratory illness.
Area of Science:
- Pediatrics
- Infectious Diseases
- Otolaryngology
Background:
- Laryngeal diphtheria presents a significant risk of respiratory obstruction in children.
- Tracheostomy is a common intervention for severe cases but carries risks.
- The efficacy of adjunctive treatments for laryngeal diphtheria requires further investigation.
Purpose of the Study:
- To evaluate the effectiveness of intravenous dexamethasone in managing respiratory obstruction in pediatric laryngeal diphtheria.
- To determine if dexamethasone can reduce the need for tracheostomy in these patients.
Main Methods:
- A cohort of 18 children with laryngeal diphtheria and varying degrees of respiratory obstruction were treated.
- Treatment included penicillin, anti-diphtheritic serum, and intravenous dexamethasone.
- Respiratory obstruction severity was monitored 12-hourly.
Main Results:
- Eleven of 12 children with mild-to-moderate obstruction showed improvement within 24 hours.
- Four of six children with severe obstruction also responded within 24 hours.
- Two children with severe obstruction required tracheostomy, and one of these died; another child died of toxaemia and renal failure post-tracheostomy.
Conclusions:
- Intravenous dexamethasone, as an adjunct therapy, appears to play a role in reducing the need for tracheostomy in pediatric laryngeal diphtheria.
- Early administration of dexamethasone may improve outcomes for children with laryngeal diphtheria and respiratory compromise.
Abstract:
Eighteen children diagnosed as having laryngeal diphtheria with various degrees of respiratory obstruction were treated with intravenous dexamethasone in addition to penicillin and anti-diphtheritic serum. Reduction in the severity of laryngeal obstruction was assessed 12-hourly. Eleven of 12 children with mild-to-moderate obstruction responded within 24 hours. The 12th child died of toxaemia and renal failure following tracheostomy. Four of six with severe obstruction also responded within 24 hours. The remaining two underwent tracheostomy, one of whom died. Dexamethasone appears to have a role to play in obviating tracheostomy in laryngeal diphtheria.
