Application of the sputum aspiration in AECOPD respiratory failure patients with noninvasive ventilation

Abstract

Objective To observe and compare the effect of opening the glottis deep suction scheme and conventional sputum suction method on the AECOPD respiratory failure patients with noninvasive ventilation.Methods Totals of 63 patients AECOPD respiratory failure patients with noninvasive ventilation were randomly divided into observation group and control group,the opening of glottis deep suction scheme was adopted in the observation group and conventional sputum suction method was adopted in the control group.Sputum suction effect such as the incidence of airway injury and pulmonary infection complication,and the blood oxygen saturation of two groups were compared.Results 18 cases had a effective treatment,one case had airway injury in the observation group,and that of the control group was 10 and 8 respectively,and the difference was statistically significant( P ＜ 0.05 ).No significant difference was found in the blood oxygen saturation before suction between two groups( P ＞ 0.05),while after suction,the blood oxygen saturation of the observation group was(98.03 ± 1.42) ％ which was significantly higher than that of the control group [ ( 96.22 ± 1.62 ) ％ ] ( P ＜0.05 ).And 2 cases had pulmonary infection in the observation group,and 5 cases of the control group,and the difference was statistically significant ( P ＜ 0.05 ).Conclusions Open glottal deep suction scheme is more effective than the conventional sputum suction method,which can reduce the incidence of complications,alleviate the suffering of patients,and improve the quality of nursing care.
