ABSTRACT

Objective To explore the associated risk factors on patients with organophosphorus poisoning combine with respiratory failure secondary pulmonary infection.Methods Two hundred and twenty-four clinical data of organophosphorus poisoning combine with respiratory failure were collected from January 2009 to May 2013.Retrospectively analyzed the situation of pulmonary infection and Logistic regression model were used to analyzed the relative risk of organophosphorus poisoning combine with respiratory failure secondary pulmonary infection.Results The secondary pulmonary infection rate of organophosphorus poisoning combine with respiratory failure was 68.75％ (154/224).Logistic regression analysis showed that combined with aspiration,hand hygiene,breathing machine,the decrease of cholinesterase activity were the relative risk factors (P ＜ 0.05).Conclusions The secondary pulmonary infection rate of organophosphorus poisoning combine with respiratory failure is higher.Combined with aspiration,hand hygiene,breathing machine,the decrease of cholinesterase activity may be the relative risk factors.
