Abstract:
Objective To investigate the change of HR,RR and arterial blood gas in the treatment of BiPAP ventilation in patients with acute pulmonary.Methods Fifty eight patients with acute pulmonary edema were randomized into two groups.The control group(n =29)were given conventional general treatment only,but treatment group(n =29)were given BiPAP ventilation besides conventional treatment.4 h later,heart rate (HR),respiratory rate(RR),SaO2,pH,PaO2 and PaCO2 were compared between the two groups.Hospitalization duration and incidence of invasive mechanical ventilation were recorded after discharge.Results Compared with pre-treatment,HR,RR,SaO2 and PaO2 in treatment group were improved significantly(HR 124 ± 12 beat/min vs 83 ±6 beat/min,t =5.372,P ＜0.01)(RR 37 ±5 beat/min vs 19 ± 8 beat/min,t =4.285,P ＜0.01)(SaO2 81.4％ ±5.4％ vs94.1％ ±4.2％,t=2.731,P＜0.05)(PaO2 53.2±5.4 mm Hg vs 89.1 ±8.5 mm Hg,t=5.763,P ＜0.O1).And these four indicators were also improved in control group after treatment,(HR 123 ± 10 beat/min vs 95 ± 8 beat/min,t =t =3.459,P ＜ 0.01)(RR 36 ± 7 beat/min vs 24 ± 6 beat/min,t =3.127,P ＜0.01)(SaO2 81.8％ ±5.7％ vs 88.3 ±4.5％％,t =2.314,P ＜0.05)(PaO2 53.5 ±4.6 mm Hg vs 72.8 ±9.5 mm Hg,t =3.756,P ＜0.01).HR,RR,SaO2 and PaO2 in treatment group were more significantly improved than that of control group(P ＜ 0.01 or P ＜ 0.05).Hospitalization duration in treatment group was significantly shorter than that of control group(9 d vs 15 d,t =3.763,P ＜ 0.01).The incidence of invasive ventilation were lower than that of control group too(but P ＞ 0.05.Conclusion These results suggested that BiPAP ventilation can regulate HR RR and blood gas value to accetable levels,shorten hoptipitalization duration and reduce the incidence of invasive ventilation.It is proved to be an effective therapeutic technique in the treatment of acute pulmonary edema patients.
