Abstract
Objectives
A prospective survey of French intensive care units (ICUs) in 1997 showed
moderate and variable use of noninvasive ventilation (NIV). This study
examined changes in NIV use in French ICUs after the intervening 5 years.
Settings
Patients were enrolled in a prospective survey in 70 French ICUs.
Methods
Three-week survey, with prospective inclusion of all patients requiring
ventilatory support.
Measurements and results
Overall 1,076 patients received ventilatory support (55% of admissions).
First-line NIV was significantly more common than 5 years earlier, overall
(23% vs. 16%) and especially in patients not intubated before ICU
admission (52% vs. 35%). Reasons for respiratory failure were coma
(33%), cardiogenic pulmonary edema (8%), acute-on-chronic respiratory
failure (17%), and de novo respiratory failure (41%). Significant
increases in NIV use were noted for acute-on-chronic respiratory failure
(64% vs. 50%) and de novo respiratory failure (22% vs. 14%).
Among patients given NIV, 38% subsequently required endotracheal
intubation (not significantly different). Independent risk factors for NIV
failure were high SAPS II and de novo respiratory failure, whereas factors
associated with success were good NIV tolerance and high body mass index.
Conclusions
NIV use has significantly increased in French ICUs during the past 5 years,
and the success rate has remained unchanged. In patients not previously
intubated, NIV is the leading first-line ventilation modality. The
proportion of patients successfully treated with NIV increased significantly
over the 5-year period (13% vs. 9% of all patients receiving
ventilatory support).
