摘　　要：目的 探究无创正压机械通气在120院前急救急性左心衰中的疗效。方法 46例120院前急救急性左心衰患者,根据随机数字表法分为对照组与观察组,每组23例。对照组患者实施常规抗心衰院前急救治疗,观察组患者在对照组基础上联合无创正压机械通气治疗。比较两组患者临床疗效及治疗前后相关指标[呼吸频率(RR)、心率(HR)、动脉血氧分压(PaO_(2))、动脉血氧饱和度(SaO_(2))以及氧合指数(PaO_(2)/FiO_(2))]。结果 治疗后,两组患者RR、HR低于本组治疗前,PaO_(2)、SaO_(2)、PaO_(2)/FiO_(2)高于本组治疗前,且观察组患者RR(18.66±2.13)次/min、HR(79.81±12.47)次/min低于对照组的(22.11±2.67)、(88.11±13.31)次/min,PaO_(2)(96.47±2.15)mm Hg(1 mm Hg=0.133 kPa)、SaO_(2)(95.77±3.03)%、PaO_(2)/FiO_(2)(258.38±15.17)mm Hg高于对照组的(90.31±4.64)mm Hg、(92.05±5.17)%、(238.51±14.03)mm Hg,差异具有统计学意义(P<0.05)。观察组患者总有效率为91.30%,高于对照组的65.22%,差异具有统计学意义(P<0.05)。结论 对120院前急救急性左心衰患者给予无创正压机械通气抢救,有助于改善患者各项血气指标,提高临床疗效,值得推广。Objective To investigate the efficacy of non-invasive positive pressure mechanical ventilation in 120 prehospital emergency patients with acute left heart failure.Methods A total of 46 cases of 120 pre-hospital emergency patients with acute left heart failure were divided into control group and observation group according to random numerical table,with 23 cases in each group.The control group received conventional pre-hospital emergency treatment of anti-heart failure,and the observation group was combined with noninvasive positive pressure mechanical ventilation on the basis of the control group.Both groups were compared in terms of clinical efficacy,related indexes[respiratory rate(RR),heart rate(HR),arterial partial pressure of oxygen(PaO_(2)),arterial oxygen saturation(SaO_(2))and oxygenation index(PaO_(2)/FiO_(2))]before and after treatment.Results After treatment,RR and HR in the two groups were lower than those before treatment in this group,while PaO_(2),SaO_(2) and PaO_(2)/FiO_(2) were higher than those before treatment in this group;RR of(18.66±2.13)times/min,HR of(79.81±12.47)times/min in the observation group were lower than those of(22.11±2.67)and(88.11±13.31)times/min in the control group;the observation group had PaO_(2) of(96.47±2.15)mm Hg(1 mm Hg=0.133 kPa),SaO_(2) of(95.77±3.03)%and PaO_(2)/FiO_(2) of(258.38±15.17)mm Hg,which were higher than those of(90.31±4.64)mm Hg,(92.05±5.17)%and(238.51±14.03)mm Hg in the control group;the differences were statistically significant(P<0.05).The total effective rate of the observation group was 91.30%,which was higher than that of 65.22%of the control group,and the difference was statistically significant(P<0.05).Conclusion For 120 pre-hospital emergency patients with acute left heart failure,non-invasive positive pressure mechanical ventilation is helpful to improve various blood and gas indicators and enhance the clinical efficacy,which is worth promoting.
