[Adult respiratory distress syndrome in childhood]
Insights
Pediatric acute respiratory distress syndrome (ARDS) is increasing, often linked to sepsis. Management includes fluid restriction, respiratory support, and oxygen transport, but mortality remains high at 95%.
Area of Science:
- Pediatric critical care medicine
- Pulmonology
- Intensive care
Background:
- Adult respiratory distress syndrome (ARDS) is increasingly recognized in pediatric populations.
- Sepsis is a near-universal comorbidity in pediatric ARDS.
- The primary mechanism involves increased pulmonary capillary permeability, leading to non-cardiogenic pulmonary edema.
Purpose of the Study:
- To outline the etiology, pathophysiology, and management of pediatric ARDS.
- To highlight critical interventions and outcomes associated with pediatric ARDS.
Main Methods:
- Review of the pathophysiology of pediatric ARDS, including capillary permeability and respiratory mechanics.
- Discussion of essential management strategies: cardiorespiratory monitoring, fluid restriction, respiratory support (PEEP/CPAP), and oxygen transport.
- Evaluation of prophylactic measures and the timing of corticosteroid administration.
Main Results:
- Pediatric ARDS presents with decreased lung compliance, functional residual capacity, and refractory hypoxemia.
- Pulmonary hypertension and low cardiac output are common complications.
- Extracorporeal oxygenation supports gas exchange but does not improve survival rates.
Conclusions:
- Effective management of pediatric ARDS requires early intervention and supportive care, including respiratory assistance and optimized oxygen transport.
- Prophylaxis hinges on prompt treatment of underlying conditions like sepsis.
- Despite intensive management, pediatric ARDS carries a high mortality rate (95%), with survivors experiencing minimal pulmonary sequelae.
Abstract:
Adult respiratory distress syndrome is becoming more frequent in pediatric age. There are several factors involved in its' etiology. Sepsis is almost invariably present in all patients. Basic mechanism is an increase of pulmonary capillary permeability with production of acute non cardiogenic oedema. The decrease in compliance and functional residual capacity produce a respiratory failure with hypoxemia non-responsive to the increase in FiO2. Pulmonary hypertension and low cardiac output appear once the syndrome has developed. In its' management, cardiorespiratory monitoring is essential. Prophylaxis is based on early treatment of the essential pathological process. Corticoids are only effective if they are administered before development of pulmonary oedema. The treatment is based on: a) Moderate water restriction. b) Early respiratory assistance using PEEP or CPAP. c) Maintenance of adequate oxygen transport. The extracorporeal oxygenation guarantees the oxygen exchange but it does not affect survival. Mortality is 95%. Patients who survive have minimal pulmonary sequelae.
