无创呼吸机辅助呼吸在重症肺炎致呼吸衰竭抢救中的应用效果分析

Application Effect of Noninvasive Ventilator Assisted Breathing in Rescue of Respiratory Failure Caused by Severe Pneumonia

目的探讨无创呼吸机辅助呼吸在重症肺炎致呼吸衰竭抢救中的应用效果。方法选取该院(2015年1月—2017年12月)收治的80例重症肺炎致呼吸衰竭患者为研究对象,随机分为两组,观察组40例患者给予无创呼吸机辅助呼吸治疗,对照组40例患者给予常规治疗,对比两组患者临床疗效和治疗前后血气指标以及呼吸频率和心率。结果观察组患者临床治疗总有效率97.50%显著高于对照组77.50%,差异有统计学意义(χ~2=18.285 7,P<0.05)。两组患者治疗前PaCO_2、PaO_2、pH血气指标对比差异无统计学意义(P>0.05);治疗后观察组患者的PaCO_2、PaO_2、pH分别为(48.38±3.24)mm Hg、(72.45±3.37)mm Hg、(7.40±0.04),观察组患者分别为(52.37±3.41)mm Hg、(64.57±3.31)mm Hg、(7.32±0.04)。治疗后两组患者PaCO_2、PaO_2、pH血气指标均有所改善,但观察组患者改善更为明显,差异有统计学意义(P<0.05)。两组患者治疗前呼吸频率和心率对比差异无统计学意义(P>0.05);治疗后两组患者呼吸频率和心率均有所改善,但观察组患者改善更为明显,差异有统计学意义(t=11.7 397、13.413 4,P<0.05)。观察组有5例(12.50%)发生并发症,对照组有21例(52.50%)发生并发症,观察组患者并发症发生率明显低于对照组,差异有统计学意义(χ~2=36.467 2,P<0.05)。结论无创呼吸机辅助呼吸在重症肺炎致呼吸衰竭抢救中的应用效果显著,可提高临床疗效,有效缓解血气指标,调整其呼吸频率和心率,促进患者生活质量改善,值得临床推广。

Objective This paper tries to explore the effect of non-invasive ventilator assisted respiration in the rescue of respiratory failure caused by severe pneumonia. Methods 80 patients with respiratolT failure caused by severe pneumonia who were admitted to this hospital（January 2015 to December 2017） were randomly divided into two groups. 40 patients in the observation group were given non-invasive ventilator-assisted respiratory therapy, and the control group was 40 with routine treatment and the clinical efficacy, blood gas parameters, and respiratory rate and heart rate were compared between the two groups. Results The total effective rate of clinical treatment in the observation group was 97.50%, which was significantly higher than that of the control group 77.50%. The difference was statistically sig- nificant （X2=18.285 7,P〈0.05）. There was no significant difference in PaC02, Pa02, pH blood gas indexes between the two groups before treatment （P〉0.05）. The PaC02, Pa02, pH of the observation group after treatment were （48.38±3.24） mmHg and （72.45±3.37）mmHg, （7.40±0.04）, observation group patients were （52.37±3.41）mmHg, （64.57±3.31）mmHg, and （7.32±0.04）, respectively. After treatment, the PaC02, Pa02, pH blood gas indexes of the two groups were improved, hut the observation group patients improved more significantly, the difference was statistically significant（P〈0.05）. There was no significant difference in respiratory frequency and heart rate between the two groups before treatment （P〉0.05）.Both respiratory rate and heart rate improved after treatment, but the improvement was more obvious in the observation group, with statistical significance （t=11.739 7,13.413 4 P〈0.05）. 5 patients （12.50%） in the observation group had complications, and 21 patients （52.50%） in the control group had complications. The incidence of complications in the observation group was significantly lower than that in the control group. The difference was statistically significant （X2= 36.467 2, P〈0.05）. Conclusion Non-invasive ventilator-assisted breathing is effective in the treatment of respiratolT failure caused by severe pneumonia. It can improve clinical efficacy, effectively relieve blood gas indexes, adjust its respiratolT rate and heart rate, and promote the improvement of patients＂ quality of life. It is worthy of clinical promo- tion.
