Abstract:Objective To investigate the effect of noninvasive positive pressure ventilation treatment on patients with acute left heart failure and hyoxemia.Methods Sixty-two patients with acute left heart failure and hyoxemia were divided into control group (31 cases) and treatment group (31 cases).All patients were treated with a conventional therapy plan and patients in treatment were received noninvasive positive pressure ventilation beside conventional therapy.Blood gas analysis,plasma B-type natriuretic peptide (BNP) and clinical manifestation before and after treatment were monitored.Results The time of clinical manifestation al0leviation in treatment group was (33.7 ±7.9) min,shorter than that of control group ((55.9 ± 12.1) min,t =8.554,P <0.01).Compared with pre-treatment,heart rate (HR),respiratory rate(RR),mean arterial pressure(MAP),pH,oxygen saturation of blood (SaO2),arterial partial pressure of oxygen (PaO2),arterial partial pressure of carbon dioxide(PaCO2) and BNP in treatment group were improved significantly(HR:(133.89 ± 5.45) beat/ min vs.(87.27 ± 5.74) beat/min,t =32.794,P < 0.01 ; RR:(34.25 ± 5.67) beat/min vs.(20.15 ± 2.54) beat/min,t =12.636,P < 0.01 ; MAP:(104.52 ± 7.25) mmHg vs.(76.57 ± 3.76) mmHg,t =19.055,P <0.01; pH:(7.29±0.06) vs.(7.40 ±0.06),t=7.218,P<0.01;SaO2:(81.52 ±5.01)% vs.(97.16±1.27) %,t =16.848,P < 0.01 ; PaO2:(55.30 ± 7.14) mmHg vs.(92.80 ± 6.24) mmHg,t =22.019,P <0.01;PaCO2:(46.23 ±10.30) mmHg vs.(40.56 ±5.19) mmHg,t =2.737,P<0.05;BNP:(831.59 ±292.65) ng/L vs.(265.52 ±65.39) ng/L,t =10.511,P <0.01).And after treatment,HR,RR,MAP,SaO2,PaO2,BNP in control group were improved compared with that before treatment (HR:(132.13 ± 5.31) beat/min vs.(92.15 ± 4.28) beat/min,t =32.638,P < 0.01 ;RR:(34.96 ± 4.78) beat/min vs.(23.91 ± 3.27) beat/min,t=l0.634,P<0.01;MAP:(102.56 ±7.14) mmHg vs.(82.83±3.52) mmHg,t =13.800,P<0.01;SaO2:(82.15 ± 5.24) % vs.(93.16 ± 2.59) %,t =10.488,P < 0.01 ; PaO2:(54.56 ± 6.27) mmHg vs.(75.19 ±3.52) mmHg,t =15.974,P <0.01 ;BNP:(823.15 ±277.26) ng/L vs.(371.15 ±87.55) ng/L,t =8.656,P <0.01).Statistical differences of pH and PaCO2 were not found in the control group before and after treatment(pH:7.32 ± 0.05,t =1.426,P =0.159 ;PaCO2:(43.78 ± 6.74) mmHg,t =0.253,P =0.801).HR,RR,MAP,pH,SaO2,PaO2,PaCO2 and BNP in treatment group were more significantly improved than that of control group(t =3.795,5.056,6.767,5.703,7.721,13.686,2.107 respectively,P < 0.01or P < 0.05).Conclusion The therapy plan of noninvasive positive pressure ventilation on patients with acute left heart failure and hyoxemia can improve cardiac function and oxygenation quickly,and decrease the plasma BNP level.
