The effects of high-flow nasal cannula on intubation and re-intubation in critically ill patients: a systematic review, meta-analysis and trial sequential analysis.

ABSTRACT:

Objective

To evaluate the efficacy of high-flow nasal cannula in the prevention of intubation and re-intubation in critically ill patients compared to conventional oxygen therapy or noninvasive ventilation.

Methods

This systematic review was performed through an electronic database search of articles published from 1966 to April 2018. The primary outcome was the need for intubation or re-intubation. The secondary outcomes were therapy escalation, mortality at the longest follow-up, hospital mortality and the need for noninvasive ventilation.

Results

Seventeen studies involving 3,978 patients were included. There was no reduction in the need for intubation or re-intubation with high-flow nasal cannula (OR 0.72; 95%CI 0.52 - 1.01; p = 0.056). There was no difference in the need for therapy escalation (OR 0.80, 95% CI 0.59 - 1.08, p = 0.144), mortality at the longest follow-up (OR 0.94; 95%CI 0.70 - 1.25; p = 0.667), hospital mortality (OR 0.84; 95%CI 0.56 - 1.26; p = 0.391) or noninvasive ventilation (OR 0.64, 95%CI 0.39 - 1.05, p = 0.075). In the trial sequential analysis, the number of events included was lower than the optimal information size with a global type I error > 0.05.

Conclusion

In the present study and setting, high-flow nasal cannula was not associated with a reduction of the need for intubation or re-intubation in critically ill patients.
