Objective: To evaluate the efficacy of Bi-level positive airway pressure (BiPAP) and continuous positive airway pressure (CPAP) on the group of chronic obstructive pulmonary disease (COPD) combined with obstructive sleep apnea hypoventilation syndrome (OSAHS) in china using Meta-analysis. Methods: Chinese knowledge resources database (CNKI), Wanfang medical network database, Weip chinese science and technology journal database (VIP) and other chinese databases were searched by computer, from database construction to January 2022. After extracting the corresponding data,
Meta-analysis was analyzed using RevMan5.4 software and Stata15.0 software. Results: 11 Chinese publications with 800 patients were finally included. The Meta-analysis showed that BiPAP improved the arterial blood pH better than CPAP (MD=0.08, 95%CI: 0.06~0.10, P<0.000 01), increase the arterial oxygen partial pressure in the patient (MD=5.56, 95%CI: 2.04~9.08, P=0.002), reduce the arterial carbon dioxide partial pressure (MD= -6.72, 95%CI: -9.99~-3.46, P<0.000 1), improve the SpO2Low (MD= 2.46, 95%CI: 1.24~3.68, P<0.000 1), improve AHI (MD= -4.14, 95%CI: -6.35~-1.92, P= 0.000 3), reduce the maximum apnea time (MD= -5.59, 95%CI: -7.85~-3.32, P<0.000 01). Among the 11 articles included, 3 introduced the adverse reactions and deaths related to treatment, 4 cases of abdominal distension, 4 cases of dry nasopharyngeal, 3 cases of pneumothorax, and 1 case of death in the BiPAP group, which were lower than 8 cases of abdominal distension, 9 cases of dry nasopharyngeal, 7 cases of pneumothorax, and 16 cases of death in the CPAP group, respectively, with statistically significant differences. Conclusion: Compared with CPAP, BiPAP was better able to relieve respiratory distress in patients with the overlapping syndrome in the Chinese population, and significantly improved the arterial blood gas index, AHI, SpO2Low and the longest apnea time. In addition, its deaths and adverse effects were lower than those in the CPAP group, confirming its safety and effectiveness.. |
