Abstract:Objective To explore the significance of serum surfactant protein A (SP-A) and surfactant protein D (SP-D) in patients with chronic obstructive pulmonary disease (COPD) complicated with respiratory failure and their prognostic value. Methods A total of 70 COPD patients hospitalized in the Department of Respiratory Medicine of Qinghai Provincial People′s Hospital from September 2015 to August 2018 were selected. They were divided into COPD group (20 cases), combined with type Ⅰ respiratory failure group (25 cases) and combined with type Ⅱ respiratory failure group (25 cases), according to the presence or absence of respiratory failure. The laboratory indicators and blood gas indicators of each group were analyzed. According to the outcome indexes of COPD patients with respiratory failure, they were divided into death group (13 cases) and non-death group (37 cases), while the prognostic risk factors were analyzed. Results The C-reactive protein of the combined type Ⅰ and type Ⅱ respiratory failure groups were lower than that of the COPD group, while SP-A and SP-D were higher than those of the COPD group, and the differences were statistically significant (P < 0.05). The pH of the combined type Ⅱ respiratory failure group was lower than that of the COPD group, and the difference was statistically significant (P < 0.05). The partial pressure of oxygen in the combined type Ⅰ and type Ⅱ respiratory failure group were lower than that in the COPD group, while combined type Ⅱ respiratory failure group was higher than combined type Ⅰ respiratory failure group, and the differences were statistically significant (P < 0.05). The partial pressure of carbon dioxide in the combined with type Ⅱ respiratory failure group was higher than those in the COPD group and the combined typeⅠrespiratory failure group, and the differences were statistically significant (P < 0.05). There were statistically significant differences between the death group and non-death group in smoking, pH, SP-A and SP-D (P < 0.05). Logistic regression analysis showed that pH was a risk factor for the prognosis of COPD combined with respiratory failure (OR > 1, P < 0.05). Conclusion In COPD patients with respiratory failure, SP-A and SP-D increased, and of little assessed value in the prognosis of COPD combined with respiratory failure, while pH has a greater assessed value of COPD combined with respiratory failure.
