Abstract：Objective：To observe the effect of the adjuvant treatment of Bo's abdominal needling on blood gas analysis， anxiety，respiratory symptoms，and the heart function of patients with chronic pulmonary heart disease complicated with type Ⅱrespiratory failure. Methods：A total of 60 cases of patients with chronic pulmonary heart disease complicated with type Ⅱ respiratory failure were selected and divided into the treatment group and the control group according to the random number table method， 30 cases in each group. The control group was given routine western medicine and noninvasive ventilator to assist respiration. The treatment group was additionally treated with Bo's abdominal needling based on the treatment of the control group. Both groups were treated for seven days. Before and after treatment，partial pressure of oxygen(PaO2) and partial pressure of carbon dioxide(PaCO2) of artery，scores of COPD Assessment Test(CAT) and Hamilton Anxiety Scale(HAMA)，N-terminal pro-brain natriuretic peptide(NT-proBNP)，pulmonary artery pressure and right ventricular end diastolic diameter(RVDD) were compared between the two groups. Results：After treatment，the levels of PaO2 in the two groups were increased when compared with those before treatment(P＜0.05)；the levels of PaCO2 and NT-proBNP were decreased when compared with those before treatment(P＜0.05)；RVDD was shortened when compared with that before treatment(P＜0.05). After treatment，when compared with those in the control group，in the treatment group，the level of PaCO2 was higher(P＜0.05)，the levels of PaCO2 and NT-proBNP were lower(P＜0.05)，and the RVDD was shorter(P＜0.05). After treatment， the scores of CAT and HAMA in the two groups were decreased when compared with those before treatment(P＜0.05)； the decrease in the treatment group was more obvious than that in the control group(P＜0.05). Conclusion：For patients with chronic pulmonary heart disease complicated with type Ⅱ respiratory failure，Bo's abdominal needling can improve indexes of blood gas analysis and the right ventricular function，relieve their respiratory tract symptoms and anxiety，and enhance respiratory tolerance.
