Pulmonary edema complicating upper airway obstruction in infants and children
1Department of Radiology, Children's Hospital of Pittsburgh, Pa.
Insights
Pulmonary edema linked to upper airway obstruction, often iatrogenic in children, resolves quickly with continuous positive airway pressure and diuretics. This treatment also helps prevent post-obstruction edema.
Area of Science:
- Pediatric Pulmonology
- Critical Care Medicine
- Otolaryngology
Background:
- Pulmonary edema can occur with acute, chronic, or post-relief upper airway obstruction.
- Iatrogenic causes like adenotonsillectomy and tracheal intubation are common in pediatric cases.
- The pathogenesis of this pulmonary edema is complex and multifactorial.
Purpose of the Study:
- To investigate the clinical settings and outcomes of pulmonary edema associated with upper airway obstruction in pediatric patients.
- To evaluate the efficacy of continuous positive airway pressure and diuretics in managing this condition.
Main Methods:
- Retrospective analysis of 21 pediatric patients with pulmonary edema and upper airway obstruction.
- Application of moderate continuous positive airway pressure (CPAP).
- Administration of diuretic therapy.
Main Results:
- Pulmonary edema was associated with acute, chronic, and immediately post-relief upper airway obstruction.
- Iatrogenic causes were frequently identified.
- Treatment with CPAP and diuretics led to rapid resolution of pulmonary edema within 24 hours.
- This therapeutic approach likely prevents post-obstruction pulmonary edema.
Conclusions:
- Continuous positive airway pressure combined with diuretics is an effective treatment for pulmonary edema related to upper airway obstruction in children.
- Prompt management can rapidly resolve edema and potentially prevent its recurrence after obstruction relief.
Abstract:
The association of pulmonary edema with upper airway obstruction occurs in three clinical settings: acute and chronic upper airway obstruction and immediately after the relief of acute upper airway obstruction. Iatrogenic causes, such as adenotonsillectomy and tracheal intubation, were the most frequently encountered in the authors' series of 21 pediatric patients with such an association. The pathogenesis of this kind of pulmonary edema is multifactorial. The application of moderate continuous positive airway pressure in conjunction with the administration of diuretics rapidly clears pulmonary edema in all three clinical settings, usually within 24 hours, and can probably prevent pulmonary edema immediately after acute obstruction is relieved.
