The study on the application of non -invasive ventilation in acute left -sided heart failure of elderly patients / 中国基层医药

ABSTRACT

Objective To analyze characteristics of patients with acute left ventricular failure,to explore application of non -invasive ventilator in elderly patients with acute left ventricular failure in first aid,and to provide reference for clinical practice.Methods The 84 cases of elderly patients with acute left ventricular failure were selected,in accordance with the random number table.They were divided into control group and treatment group,both groups were given conventional drugs and methods of treatment,while the treatment group was treated by using of non-invasive ventilator -assisted therapy based on the control group.The main changes in physiological indicators of treatment,clinical efficacy and prognosis of the two groups were compared.Results After treatment,in the control group,the clinical total effective rate was 61.9%,while in the treatment group was 88.1%,there were significant differences (χ2 =3.841,P <0.05).Before treatment,RR,HR,SBP,PaO2 and SaO2 of the control group were (28.70 ± 1.01)min,(133.22 ±13.20)min,(112.87 ±14.02)mmHg,(55.60 ±10.56)mmHg and (80.25 ±3.26)%respectively,while the data after treatment were (20.04 ±1.42)min,(95.83 ±14.56)min,(96.08 ±13.84)mmHg, (79.86 ±11.69)mmHg and (90.24 ±3.45)%.Before treatment,RR,HR,SBP,PaO2 and SaO2 of the treatment group were (28.87 ±1.34)min,(135.36 ±10.98)min,(110.90 ±13.65)mmHg,(57.80 ±11.35)mmHg and (81.33 ±3.34)%,while the data after treatmen was (15.86 ±1.13 )min,(84.22 ±11.82)min,(84.26 ± 10.27)mmHg,(89.31 ±12.21)mmHg and (99.35 ±3.96)%.Arterial blood gas indicators in the two groups had improved(t≥5.523,P <0.05),but the degree of improvement in the treatment group compared with the control group was significant difference (t =14.927,4.186,4.445,3.834,11.241,all P <0.05).The turnaround time of the treatment group was (12.7 ±4.1)h,which was significantly lower than that of control group[(20.8 ±5.6)h (t =7.563,P <7.563)].The length of hospital stay in treatment group was (11.8 ±3.9)d,significantly shorter than that in the control group[(18.5 ±4.9)d (t =6.933,P <0.05)].The mortality of treatment group was 2.38%,which was significantly lower than 16.67% of control group (χ2 =2.488,P <0.05).Conclusion On the basis of conven-tional treatment,the use of non -invasive ventilator -assisted therapy in elderly patients with acute left ventricular failure,can significantly improve the main physiological indicators,the effect of improving the clinical treatment and the prognosis is good.
