Insights
Prolonged mechanical ventilation in children is common, affecting 36%. Key risk factors include young age, high initial illness severity, and early use of noninvasive ventilation or continuous sedation.
Area of Science:
- Pediatric critical care medicine
- Respiratory medicine
Background:
- Prolonged invasive mechanical ventilation is associated with increased morbidity and mortality in critically ill children.
- Identifying early risk factors is crucial for timely intervention and improved outcomes.
Purpose of the Study:
- To determine the incidence rate of prolonged acute invasive mechanical ventilation in children.
- To identify early risk factors associated with prolonged mechanical ventilation.
Main Methods:
- Retrospective longitudinal cohort study of 360 pediatric intensive care unit patients over one year.
- Logistic regression analysis was used to identify risk factors for ventilation lasting ≥96 hours versus <96 hours.
Main Results:
- 36% of patients required prolonged mechanical ventilation (≥96 hours).
- Significant risk factors included age <12 months, high Pediatric Risk of Mortality score (≥15), elevated mean airway pressure (≥13 cm H2O) on day 1, continuous intravenous sedation on day 1, and prior noninvasive ventilation.
Conclusions:
- Early noninvasive ventilation and continuous intravenous sedation are associated with prolonged mechanical ventilation in children.
- Further research into sedation protocols is warranted to optimize ventilation duration.
Background:
Invasive mechanical ventilation, if prolonged, may lead to high morbidity and mortality.
Objective:
To determine the incidence rate and early risk factors for prolonged acute invasive mechanical ventilation in children.
Design:
Retrospective longitudinal cohort study over a 1-yr period.
Patients:
All consecutive episodes of invasive mechanical ventilation in the pediatric intensive care units of Sainte-Justine Hospital (Montreal, Canada) were included. Risk factors for long (≥96 hrs) vs. short (<96 hrs) duration of ventilation were determined by logistic regression.
Intervention:
None.
Measurements And Main Results:
Among the 360 episodes of invasive ventilation, 36% had a length of ≥96 hrs. Following multivariate analysis, significant risk factors for prolonged acute invasive mechanical ventilation were age of <12 months (odds ratio 3.27, 95% confidence interval 1.90-5.63), Pediatric Risk of Mortality score of ≥15 at admission (odds ratio 3.41, 95% confidence interval 1.31-8.89), mean airway pressure of ≥13 cm H(2)O on day 1 (odds ratio 5.92, 95% confidence interval 3.08-11.36), use of continuous intravenous sedation on day 1 (odds ratio 1.75, 95% confidence interval 1.00-3.05), and use of noninvasive ventilation before intubation (odds ratio 6.56, 95% confidence interval 1.99-21.63).
Conclusions:
Among the risk factors identified, the use of noninvasive ventilation and continuous intravenous sedation on the first day of ventilation are the only two interventions that were associated with prolonged acute invasive mechanical ventilation. Further research is needed to study the impact of sedation protocols on the duration of mechanical ventilation in children.
