OBJECTIVE: To study the effect of tongfei mixture (TFM, a Chinese recipe mainly consisted of angelica and rehmannia root) on nocturnal hypoxia in patients with chronic obstructive pulmonary disease (COPD). METHODS: Sixty patients with COPD of remission phase were randomly divided into 3 groups, 20 in each group. Group A was the control group; Group B, the group simply treated with oxygen; Group C, treated with oxygen and TFM. Changes of pulmonary function, diaphragm muscle mobility (DMM), 6 min walk distance (6MWD), morning arterial blood gas, nocturnal lowest oxygen saturation (LSaO2), mean blood oxygen saturation (MSaO2), the percentage of saturation lower than 90% time account for total sleeping time (SLT90%) and ultrasonocardiogram before and after treatment were observed. RESULTS: Levels of LSaO2, MSaO2 and SLT90% in Groups B and C were significantly higher than those in Group A (P<0.05, P<0.01). The lowering of PaCO2 in Group C was more significant than that in Group B (P<0.05). The mPAP level in Group C was lower, FEV1, 6MWD and DMM were improved than those in Group A and B, showing significant difference (P<0.05). CONCLUSION: Combined use of oxygen therapy and TFM could not only improve the nocturnal hypoxia, but also lower PaCO2. TFM is an important supplement of oxygen therapy.
