High-flow nasal cannula in adults with acute respiratory failure and after extubation : a systematic review and meta-analysis
BACKGROUND: High-flow nasal cannula (HFNC) can be used as an initial support strategy for patients with acute respiratory failure (ARF) and after extubation. However, no clear evidence exists to support or oppose HFNC use in clinical practice. We summarized the effects of HFNC, compared to conventional oxygen therapy (COT) and noninvasive ventilation (NIV), on important outcomes including treatment failure and intubation/reintubation rates in adult patients with ARF and after extubation.
METHODS: We searched 4 electronic databases (Pubmed, EMBASE, Scopus, and Web of Science) to identify randomized controlled trials (RCTs) comparing the effects of HFNC with either COT or NIV on rates of 1) treatment failure and 2) intubation/reintubation in adult critically ill patients.
RESULTS: We identified 18 RCTs (n = 4251 patients) in pooled analyses. As a primary mode of support, HFNC treatment reduced the risk of treatment failure [Odds Ratio (OR) 0.65; 95% confidence interval (CI) 0.43-0.98; p = 0.04; I2 = 32%] but had no effect on preventing intubation (OR, 0.74; 95%CI 0.45-1.21; p = 0.23; I2 = 0%) compared to COT. When used after extubation, HFNC (vs. COT) treatment significantly decreased reintubation rate (OR 0.46; 95%CI 0.33-0.63; p < 0.00001; I2 = 30%) and extubation failure (OR 0.43; 95%CI 0.25-0.73; p = 0.002; I2 = 66%). Compared to NIV, HFNC significantly reduced intubation rate (OR 0.57; 95%CI 0.36-0.92; p = 0.02; I2 = 0%) when used as initial support, but did no favorably impact clinical outcomes post extubation in few trials.
CONCLUSIONS: HFNC was superior to COT in reducing treatment failure when used as a primary support strategy and in reducing rates of extubation failure and reintubation when used after extubation. In few trials, HFNC reduced intubation rate compared to NIV when used as initial support but demonstrated no beneficial effects after extubation.
