Abstract [Objective] To observe the incidence of postoperative pulmonary infection in senile acute abdomen and to analyze the associated risk factors in order to reduce the incidence of postoperative pulmonary infection in se-nile acute abdomen .[Methods]Totally 114 senile patients with acute abdomen undergoing surgery were analyzed respectively .The incidence of postoperative pulmonary infection was calculated .The associated risk factors were tested by single factor χ2 test and multi-factor Logistic regression analysis .[Results] Among the 114 patients ,30 patients had postoperative pulmonary infection ,and the incidence rate was 26 .32% .The multi-factor Logistic test showed that age(OR= 2 .356 ,95% CI 1 .845~3 .009) ,the combined pulmonary diseases(OR= 3 .526 ,95% CI 2 .346~5 .300) ,general anesthesia(OR= 3 .410 ,95% CI 2 .469~ 4 .710) ,sputum excretion by oneself (OR=0 .472 ,95% CI 0 .335~0 .665) ,sputum excretion by others (OR=0 .503 ,95% CI 0 .394~0 .642) ,mouth clean (OR=0 .481 ,95% CI 0 .369~0 .627) ,anemia(OR=1 .821 ,95% CI 1 .632~2 .032) ,poor immune function(OR=2 .526 ,95% CI 1 .887~3 .381) and hospital stay (OR=1 .793 ,95% CI 1 .421~2 .262) were the risk factors for postoperative pulmonary infection .[Conclusion] The incidence of postoperative pulmonary infection is high in eld-erly patients with acute abdomen ,and is associated with a variety of factors .On the basis of the relevant risk fac-tors ,the prevention ,treatment and nursing during the operation should be strengthened .
