Dexamethasone for the prevention of postextubation airway obstruction: a prospective, randomized, double-blind,
1Department of Pediatrics, Children's Hospital of Michigan, Wayne State University School of Medicine, Detroit, USA.
Insights
Dexamethasone pretreatment significantly reduced airway obstruction in young children after mechanical ventilation. This steroid intervention lowered the need for racemic epinephrine and reintubation, improving patient outcomes.
Area of Science:
- Pediatric Critical Care Medicine
- Pharmacology
- Respiratory Medicine
Background:
- Postextubation airway obstruction is a significant concern in pediatric intensive care.
- Identifying effective preventative strategies is crucial for improving patient outcomes and reducing complications.
Purpose of the Study:
- To evaluate the efficacy of dexamethasone in preventing airway obstruction following extubation in young children.
- To assess the impact of dexamethasone on key indicators of airway compromise and the need for rescue therapies.
Main Methods:
- A prospective, randomized, double-blind, placebo-controlled trial was conducted in a university teaching hospital's pediatric intensive care unit.
- Sixty-six children under 5 years old, ventilated for over 48 hours, received either intravenous dexamethasone or a placebo before elective extubation.
- Outcomes measured included stridor, Croup Score, pulsus paradoxus, and the need for racemic epinephrine or reintubation.
Main Results:
- Dexamethasone significantly reduced the frequency of stridor, Croup Score, and pulsus paradoxus at multiple time points post-extubation.
- Fewer patients in the dexamethasone group required aerosolized racemic epinephrine (4/31 vs. 22/32, p < .0001).
- Reintubation rates were significantly lower in the dexamethasone group (0/31 vs. 7/32, p < .01).
Conclusions:
- Pretreatment with dexamethasone is effective in decreasing the incidence and severity of postextubation airway obstruction in pediatric patients.
- Dexamethasone represents a valuable therapeutic option for preventing airway complications after extubation in children.
- The study supports the use of corticosteroids to mitigate airway-related adverse events in this vulnerable population.
Objective:
To determine whether dexamethasone prevents postextubation airway obstruction in young children.
Design:
Prospective, randomized, double-blind, placebo-controlled study.
Setting:
Pediatric intensive care unit of a university teaching hospital.
Patients:
Sixty-six children, < 5 yrs of age, intubated and mechanically ventilated for > 48 hrs.
Interventions:
Patients were randomized to receive intravenous dexamethasone (0.5 mg/kg, maximum dose 10 mg) or saline, every 6 hrs for six doses, beginning 6 to 12 hrs before elective extubation.
Measurements And Main Results:
Dependent variables included the presence of stridor, Croup Score, and pulsus paradoxus at 10 mins, 6, 12, and 24 hrs after extubation; need for aerosolized racemic epinephrine and reintubation. The dexamethasone and placebo groups were similar in age (median 3 months [range 1 to 57] vs. 4 months [range 1 to 59], p = .6), frequency of underlying airway anomalies (3/33 vs. 3/33, p = 1.0), and duration of mechanical ventilation (median 3.3 days [range 2.1 to 39] vs. 3.5 days [range 2.1 to 15], p = .7). The dexamethasone group had a lower frequency of stridor, Croup Score, and pulsus paradoxus measurement at 10 mins and at 6 and 12 hrs after extubation. Fewer dexamethasone-treated patients required epinephrine aerosol (4/31 vs. 22/32, p < .0001) and reintubation (0/31 vs. 7/32, p < .01). Three patients exited the study early-one patient in the dexamethasone group had occult gastrointestinal hemorrhage and one patient in each group had hypertension.
Conclusion:
Pretreatment with dexamethasone decreases the frequency of postextubation airway obstruction in children.
