ABSTRACT

Objective To observe and investigate the effect of bronchoalveolar lavage (BAL)joint non -invasive positive pressure ventilation (NIPPV)in treatment of chronic obstructive pulmonary disease(COPD)with type II respiratory failure.Methods 110 patients of COPD combined with type Ⅱrespiratory failure were selected. According to the random number table method,all the patients were divided into observation group and control group. Except routine therapy,the observation group was treated with BAL combined with NIPPV treatment,the control group was treated with NIPPV treatment alone.The heart rate,APACHE Ⅱscore changes,blood gas index,mean arterial pressure and adverse reactions occurrences were compared between the two groups.Results Four hours after treatment,the pH of the observation group was significantly increased to (7.36 ±0.06),and compared with the control group (7.32 ±0.05),the difference was statistically significant (t =3.798,P 0.05).12h after treatment,APACHE II scores of the two groups were significantly decreased,in the observation group,the APACHE II score from (10.8 ±2.5)points decreased to (7.8 ±1.9)points,and in the control group,the APACHE II score from (11.8 ±4.3)points decreased to (9.9 ± 4.5)points,APACHE II score of the observation group decreased more obviously than the control group,and the difference was statistically significant (t =-3.188,P <0.05).The incidence rate of adverse reaction of the observation group (18.18%)was significantly lower than the control group (63.64%).Conclusion BAL combined with NIPPV in the treatment of COPD with type II respiratory failure can effectively improve symptoms in patients with breathing difficulties,improve PaO2 level,reduce PaCO2 level and APACHE II score,and reduce the incidence of adverse reactions,which has good clinical application value.
