摘要
Abstract
Objective To investigate the risk factors of ventilator-associated pneumonia(VAP)in elderly patients and the distribution condition of pathogens,and to provide evidence for the prevention and treatment of VAP.Methods The clinical data of 78 elderly patients with mechanical ventilation time of over 48 hours in ICU of our hospital were retrospectively analyzed,and the patients were divided into VAP group and non-VAP group.Results The ICU hospitalization time and mechanical ventilation time of patients in VAP group were all longer than those in non-VAP group.The ratios of patients with tracheal intubation again,use of acid suppression agent,and gastroesophageal reflux and aspiration in VAP group wereall higher than those in non-VAP group,and the difference was statistically significant(P<0.05).59 strains of pathogenic bacteria were detected in all of the 45 cases of patients with VAP,of which the gram negative bacteria were 41strains,accounting for 69.5%,significantly higher than the gram positive bacteria(14 strains,23.7%)and fungi(4 strains,6.8%).Conclusion The ICU hospitalization time,mechanical ventilation time,re tracheal intubation,the use of acid suppression agent,and gastroesophageal reflux and aspiration of patients are risk factors for VAP in elderly patients.关键词
