目的探讨无创呼吸机治疗ICU病房心力衰竭(HF)合并呼吸衰竭(RF)患者的临床疗效。方法选取兰考县人民医院2011年3月—2014年3月ICU收治的90例HF合并RF患者,随机分为对照组45例和研究组45例。对照组采用低流量持续吸氧和常规药物治疗,研究组在对照组基础上给予无创呼吸机治疗,比较两组临床疗效及血气分析指标[动脉血氧分压(PaO_2)、p H值、动脉血二氧化碳分压(PaCO_2)]。结果研究组临床疗效优于对照组,差异有统计学意义(P<0.05)。治疗前两组患者血气分析指标比较,差异无统计学意义(P>0.05);治疗后研究组患者p H值高于对照组,PaCO_2低于对照组,差异有统计学意义(P<0.05),治疗后两组患者p H值高于治疗前,PaCO_2低于治疗前,差异有统计学意义(P<0.05)。两组并发症发生率比较,差异无统计学意义(P>0.05)。结论 ICU病房采用无创呼吸机治疗HF合并RF患者,操作简单迅速,无需插管,适合ICU病房的紧急抢救,并且无创呼吸机(CPAP)可显著改善患者血气水平,提高临床治疗效果。
Objective To investigate the clinical efficacy of noninvasive ventilator in patients with ICU ward heart failure (HF) and respiratory failure (RF). Methods 90 patients with HF complicated with RF admitted to Lankao County People’s Hospital from March 2011 to March 2014 were randomly divided into control group (n = 45) and study group (n = 45). The control group was treated with low-flow continuous oxygen inhalation and routine drug treatment. The study group was given non-invasive ventilator on the basis of the control group. The clinical efficacy and blood gas analysis indexes (PaO_2, p H, arterial Blood carbon dioxide partial pressure (PaCO_2)]. Results The clinical efficacy of the study group was better than that of the control group, the difference was statistically significant (P <0.05). There was no significant difference in blood gas analysis index between the two groups before treatment (p> 0.05). After treatment, the p H value in the study group was higher than that in the control group, PaCO 2 was lower than that in the control group, the difference was statistically significant (P0.05) After treatment, the p H value of the two groups was higher than that before treatment, PaCO 2 was lower than before treatment, the difference was statistically significant (P <0.05). There was no significant difference in the complication rates between the two groups (P> 0.05). Conclusion The ICU ward with noninvasive ventilator for patients with HF complicated with RF has the advantages of simple and quick operation, no need of intubation, emergency rescue in ICU ward, and noninvasive ventilator (CPAP) can significantly improve blood gas level and improve clinical effect.
