探讨早期与延迟无创呼吸机辅助治疗急性左心衰竭并发Ⅱ型呼吸衰竭的临床疗效

Explore the clinical efficacy of early and delayed noninvasive ventilator-assisted therapy for type 2 respiratory failure in patients with acute left heart failure

目的探讨早期与延迟无创呼吸机辅助治疗急性左心衰竭并发Ⅱ型呼吸衰竭的临床疗效。方法选取2017年1月~2017年10月本院确诊的急性左心衰竭并发Ⅱ型呼吸衰竭患者60例,按随机对照、双盲法分为两组,对照组30例患者,采取延迟无创呼吸机辅助治疗,观察组30例患者,采取早期无创呼吸机辅助治疗,观察两组治疗后心率(HR)、呼吸频率(RR)、血氧分压(PaO_2)及平均动脉压(MAP),比较两组治疗效果。结果观察组治疗后HR、RR、MAP水平均低于对照组,PaO_2水平高于对照组,差异有统计学意义(P<0.05);观察组治疗总有效率高于对照组,差异有统计学意义(P<0.05)。结论对急性左心衰竭并发Ⅱ型呼吸衰竭患者实施早期早期无创呼吸机辅助治疗,可快速恢复患者血气指标,改善患者临床症状。

Objective To investigate the clinical effects of early and delayed noninvasive ventilator-assisted therapy on acute left heart failure complicated with typeⅡrespiratory failure.Methods From January 2017 to October 2017,60 patients with acute left ventricular failure and typeⅡrespiratory failure diagnosed in our hospital were randomly divided into two groups according to randomized controlled trials and 30 patients in control group.The non-invasive Ventilator-assisted therapy and observation group of 30 patients were treated with early non-invasive ventilator-assisted therapy.HR,RR,PaO2 and MAP were observed after treatment.Compare the treatment effect of two groups.Results The levels of HR,RR and MAP in the observation group were lower than those in the control group and PaO2 levels were higher than those in the control group(P<0.05).The total effective rate in the observation group was higher than that in the control group,There was a statistically significant difference(P<0.05).Conclusion The early early noninvasive ventilator-assisted therapy for patients with acute left heart failure complicated with typeⅡrespiratory failure can quickly recover the blood gas indexes and improve the clinical symptoms.
