Positive pressure ventilation can safely support children with epiglottitis. Prompt antibiotic and steroid treatment improves airway obstruction within 8-12 hours, allowing earlier extubation.
Area of Science:
- Pediatric Anesthesiology
- Pediatric Emergency Medicine
- Otolaryngology
Background:
- Epiglottitis can cause severe upper airway obstruction in children.
- Previous treatments like IPPB and nebulized racemic epinephrine were often ineffective for epiglottitis-related obstruction.
- Anesthesiologists' experience prompted a review of 28 pediatric epiglottitis cases over 5 years.
Purpose of the Study:
- To evaluate the efficacy of positive pressure ventilation in pediatric epiglottitis.
- To assess the impact of combined antibiotic and steroid therapy on airway obstruction.
- To determine optimal timing for extubation in treated epiglottitis cases.
Main Methods:
- Retrospective review of 28 pediatric epiglottitis cases treated over a 5-year period.
- Analysis of treatment responses to positive pressure ventilation (mouth or machine).
- Evaluation of outcomes with high-dose antibiotic and steroid therapy.
Main Results:
- Positive pressure ventilation was found to be beneficial and life-saving in obstructed epiglottitis patients, contrary to previous beliefs.
- Half of the patients required airway support, with five undergoing tracheal intubation.
- Significant improvement in airway obstruction was observed 8-12 hours after initiating antibiotic-steroid therapy.
Conclusions:
- Positive pressure ventilation is a safe and effective supportive measure for pediatric epiglottitis.
- Aggressive antibiotic and steroid treatment can rapidly resolve severe airway obstruction.
- Early extubation is feasible within 8-12 hours of treatment initiation based on observed improvements.
Abstract:
Because of our experience, as anesthesiologists, in the treatment of upper airway obstructions, we have been asked to see children with epiglottitis. Over a 5-year period, we have treated 28 such cases. Our hope that IPPB and nebulized racemic epinephrine would quickly relieve the obstruction, as it has in laryngotracheobronchitis, did not materialize. The obstruction from the edematous aryepiglottic folds and other hypopharyngeal structures was not relieved by such treatment, and half required an artificial airway, five by tracheal intubation. However, we documented two facts: (1) that the obstructed patient with epiglottitis can be ventilated and benefited by positive pressure by mouth or machine and that this ventilatory support can be life saving, rather than worsening the obstruction as was previously thought; (2) that with heavy-dose antibiotic-steroid therapy, the severe obstruction can be expected to improve significantly 8 to 12 hours after the onset of treatment. With this observation, we have extubated our patients at this time, rather than at 24 hours or later.
