Non-invasive ventilation (NIV) use increased significantly in pediatric intensive care units for bronchiolitis, leading to reduced invasive ventilation (IV) and shorter hospital stays.
Area of Science:
- Pediatric Intensive Care
- Respiratory Medicine
- Critical Care
Background:
- Acute bronchiolitis is a common cause of pediatric intensive care unit (PICU) admission.
- Ventilatory support, including non-invasive ventilation (NIV) and invasive ventilation (IV), is crucial for managing severe cases.
Purpose of the Study:
- To analyze the 12-year trend in the utilization of NIV and IV for pediatric patients with acute bronchiolitis.
- To compare ventilation strategies and outcomes between the first and second halves of the study period.
Main Methods:
- Retrospective observational study of 196 children admitted to the PICU for acute bronchiolitis between 2001 and 2012.
- Analysis of demographic data, ventilation methods (NIV vs. IV), and clinical outcomes.
- Comparison of data from the first six years (2001-2006) versus the last six years (2007-2012).
Main Results:
- NIV use increased from 79.4% to 100%, while IV use decreased from 46% to 22.6% over the study period.
- Continuous positive airway pressure and nasopharyngeal tubes were common, with increased use of bi-level NIV and nasal cannulas in the latter period.
- Median duration of IV was 9.5 days, NIV was 3 days, and PICU length of stay was 7 days, with a shorter stay in the second period.
Conclusions:
- The increasing adoption of NIV for bronchiolitis in the PICU correlated with a decline in IV use.
- This shift towards NIV was associated with a reduced length of PICU stay.
