Objective: The aim of this study was to investigate the clinical effect of Danhong injection combined with western medicine treatment in patients with respiratory failure. Method: Eighty patients admitted to our hospital with respiratory failure were analyzed

according to the different treatment regimens

divided into control group and experiment group. The control group was given western medicine

while the experiment group was given Danhong injection combined with western medicine treatment

and the efficacy were compared. Result: In experiment group

the efficacy was 95%

higher than control group (85%) (P<0.05);95% patients of the experiment group were satisfied with the therapy

which was higher than control group (65%) (P<0.01);in experiment group erythrocyte aggregation index was (1.35±0.10)

plasma viscosity was (4.18±0.25) mPa · s

hematocrit was (0.41±0.07)

fibrinogen was (3.14±1.20) g · L-1

which were all lower than in the control group (P<0.05);in experiment group

pH indicators(7.47± 0.07) and PaO2 indicators (75.77±8.32) mmHg were both higher than the control group (P<0.05);in experiment group PaCO2 indicators (46.49±4.54) mmHg was lower than the control group (P<0.05);in the experiment group

6-min walking distance after treatment was (372.5±57.3) m

longer than in the control group (P<0.05). Conclusion: The respiratory failure has high incidence

and the use of Danhong injection combined with western medicine clinically should be introduced.
