Effects of naloxone hydrochloride on pulmonary function, blood gas changes and inflammatory factors in patients with COPD combined with respiratory failure

摘要

Objective: To investigate the effects of naloxone hydrochloride on pulmonary function, blood gas changes and inflammatory factors in patients with COPD combined with respiratory failure. Methods: According to random data table method, 80 cases of COPD combined with respiratory failure were randomly divided into the control group (n=40) and observation group (n=40), patients in the control group were treated with noninvasive positive pressure ventilation on the basis of routine symptomatic treatment, on the basis of the treatment of the control group, the observation group received naloxone hydrochloride therapy. The levels of pulmonary function, blood gas changes and inflammatory factors were compared in two groups before and after treatment. Results: The levels of serum FEV1, FVC, PEF, PaCO2, PaO2, PaO2/FiO2, TNF-α and PCT in the two groups before treatment were not statistically significant. After treatment, the levels of FEV1, FVC, PEF in the control group and observation group were (70.01±0.36)％, (2.16±0.41) L, (2.98±0.45) L/s and (81.71±0.53)％, (3.65±0.55) L, (4.36±0.43) L/s, which were significantly higher than those in the same group before treatment, and the levels in observation group were significantly higher than those in the control group; the levels of PaCO2, PaO2 and PaO22/FiO2 in the two groups were (59.62±6.47) mmHg, (65.53±7.36) mmHg, (323.89±10.47) and (46.59±6.64) mmHg, (73.65±8.26) mmHg, (398.64±14.06), compared with the same group before treatment, PaCO2 levels were significantly lower in both groups, and the observation group was significantly lower than the control group, PaO2,PaO2/FiO2 levels were significantly increased in both groups, and the observation group was significantly higher than the control group; the levels of TNF-α, PCT in the two groups were (23.28±4.53) pg/mL, (5.22±2.13) ng/mL and (16.61±4.12) pg/mL, (2.07±1.21) ng/mL, which were significantly lower than those in the same group before treatment, moreover, the observation group levels were significantly lower than those in the control group. Conclusion:Treatment of COPD with respiratory failure by naloxone hydrochloride can effectively reduce the level of inflammatory factors, and improved lung function and blood gas levels, which has important clinical value.
