Influence of lung suctioning method on mechanical ventilation related pulmonary infection of patients after cardiac valve replacement / 中国实用护理杂志

ABSTRACT

Objective To observe the effect of lung suctioning method on mechanical ventilation related pulmonary infection of patients after cardiac valve replacement. Methods 102 patients of mechanical ventilation related pulmonary infection after cardiac valve replacement were randomly divided into the treatment group( 50 patients )and the control group( 52 patients ). The treatment group received intervention of lung suctioning method and the control group adopted routine sputum aspiration. The pulmonary infection rate and blood gas analysis before and after the treatment were observed and the cure rate and the positive rate of specimen of sputum were recorded. Results The pulmonary infection rate of the treatment group was lower than the control group;PaO2 and SaO2 were obviously different after treatment in the control group, but no difference in the treatment group. The cure rate of pulmonary infection patients in the treatment group was higher than those in the control group. Conclusions The intervention of lung suctioning method was a safe and effective method to improve hypoxemia and abate the rate of pulmonary infection.
