目的观察急诊应用呼吸机治疗急性左侧心力衰竭的临床效果。方法 60例急性左侧心力衰竭患者,采取数字随机法分成观察组和对照组,每组30例。对照组采取常规治疗,观察组在常规治疗基础上采取呼吸机治疗,比较两组临床治疗效果及动脉血气水平。结果观察组显效17例,显效率为56.67%,有效10例,有效率为33.33%,无效3例,无效率为10.00%,总有效率为90.00%;对照组显效8例,显效率为26.67%,有效13例,有效率为43.33%,无效9例,无效率为30.00%,总有效率为70.00%;观察组患者总有效率高于对照组,差异有统计学意义(P<0.05)。治疗后两组患者动脉血二氧化碳分压(PaCO_2)、血氧分压(PaO_2)、血氧饱和度(Sp O2)水平均优于治疗前,且观察组患者优于对照组,差异均有统计学意义(P<0.05)。结论急诊应用呼吸机治疗急性左侧心力衰竭的临床效果显著,可改善常规综合治疗效果,临床价值较高。
Objective To observe the clinical application of emergency ventilator in the treatment of acute left heart failure. Methods Sixty patients with acute left heart failure were randomly divided into observation group and control group with 30 cases in each group. The control group to take conventional treatment, the observation group on the basis of conventional treatment with ventilator therapy, the clinical efficacy and arterial blood gas levels were compared between the two groups. Results In the observation group, the effective rate was 56.67%, the effective rate was 33.33%, the effective rate was 33.33%, the ineffective rate was 10.00% and the total effective rate was 90.00%. In the control group, 8 cases were markedly effective and the effective rate was 26.67 %, Effective in 13 cases, effective rate was 43.33%, ineffective in 9 cases, ineffective rate was 30.00%, total effective rate was 70.00%; total effective rate in observation group was higher than that in control group, the difference was statistically significant (P <0.05) . PaCO 2, PaO 2 and Sp O 2 were better in both groups after treatment than those before treatment, and the patients in the observation group were superior to the control group with statistical differences Significance (P <0.05). Conclusion The clinical application of emergency ventilator in the treatment of acute left heart failure is significant, which can improve the effect of conventional comprehensive therapy and has high clinical value.
