有创—无创序贯性机械通气抢救重症呼吸衰竭的临床研究
[摘要] 目的 探讨有创-无创序贯性机械通气抢救重症呼吸衰竭的临床效果。方法 方便选取该院于2016年2月”2018年2月所收治的重症呼吸衰竭患者86例,随机分为对照组和研究组,分别行持续有创机械通气治疗及有创-无创序贯性机械通气治疗,观察并比较两组患者治疗前后的血气指标水平变化情况、治疗用时及治疗效果。结果 两组患者治疗前RR、HR、PaCO2、PaO2及pH等各项血气指标水平比较差异无统计学意义(t=0.316、0.403、0.026、0.207、0.014,P>0.05),研究组治疗后各项血气指标水平较对照组均更优(t=8.213、15.904、8.062、11.453、5.045,P<0.05);研究组患者有创通气时间、总机械通气时间及住院时间较对照组均明显更短(t=8.337、11.026、7.403,P<0.05);研究组呼吸机相关肺炎的发生率、脱机失败率及死亡率(9.30%、13.95%、11.63%)较对照组(32.56%、41.86%、41.86%)均明显更低,差异有统计学意义(χ2=6.023、6.131、6.274,P<0.05)。结论 有创-无创序贯性机械通氣抢救重症呼吸衰竭患者具显著临床效果,且安全性较高,值得在临床当中推广应用。

[Abstract] Objective To investigate the clinical effect of invasive-non-invasive sequential mechanical ventilation in the treatment of severe respiratory failure. Methods 86 patients with severe respiratory failure admitted to the hospital from February 2016 to February 2018 were convenient selected and divided into the control group and the study group. They underwent continuous invasive mechanical ventilation and invasive-non-invasive sequential machinery, ventilation therapy, observe and compare the changes of blood gas index levels before and after treatment, treatment time and treatment effect. Results There were no significant differences in blood gas index between the two groups before treatment (RR, HR, PaCO2, PaO2, pH, etc.) (t=0.316, 0.403, 0.026, 0.207, 0.014, P>0.05), the blood gas index level of the study...
