Efficacy of high-flow nasal cannula on acute exacerbation of chronic obstructive pulmonary disease: A meta-analysis
Journal Title: Medical Data Mining - Year 2019, Vol 2, Issue 4
Abstract
Objective: To systematically evaluate the efficacy and feasibility of high-flow nasal cannula (HFNC) on patients with acute exacerbation of chronic obstructive pulmonary disease (AECOPD). Methods: Systematic searches on PubMed, Web of Science, the Cochrane Library, Embase, CBM (Chinese Biomedicine Database), CNKI (China National Knowledge Infrastructure), Wanfang Database and VIP were performed for randomized controlled trials (RCTs) which explored the effects of HFNC on patients with AECOPD. The retrieval time was from the establishment of each database to July 2019. RevMan5.3 software was used for statistical analysis. Results: A total of 12 articles were included, involving 812 patients. The results showed that: (1) Compared with conventional oxygen therapy, HFNC could improve patients' arterial partial oxygen pressure (PaO2) (MD = 12.70, 95% CI (7.00,18.40), Z = 4.37, P < 0.0001), reduce partial arterial blood carbon dioxide (PaCO2) (MD = -10.99, 95% CI (-14.42, -7.55), Z = 6.26, P < 0.00001) and reduce endotracheal intubation rate (OR = 0.19, 95% CI (0.04, 0.93), Z = 2.05, P = 0.04), shorten the hospitalization time (SMD = -0.74, 95% CI (-1.11,-0.37), Z = 3.95, P < 0.0001). (2) Compared with non-invasive positive pressure ventilation, it has fewer adverse reactions (OR = 0.18, 95% CI (0.09, 0.35), Z = 5.08, P < 0.00001) and shorter hospital stay (SMD = -0.57,95% CI (-0.90,-0.23), Z = 3.33, P = 0.0009). Conclusion: HFNC can improve the patients’ hypoxia symptoms and CO2 retention, reduce the rate of tracheal intubation, and alleviate adverse reactions. However, Limited by the quality and region of the included studies, more high-quality are needed to test it.
