Abstract：Objective To study the factors associated with the occurrence of hospital acquired pneumonia after aseptic operation.Methods The study enrolled 32 patients who had hospital-acquired pneumonia(infection group) and 70 patients who did not have hospital-acquired pneumonia(control group)after aseptic operation.Clinical data and metabolic characteristics were analyzed (gender,age,pulmonary underlying disease,diabetes,application of preventive antibiotics,temporarily prescribed antibiotics during operation,application of antacids,preoperative pulmonary function/blood and gas,operation time,length of operation and postoperative oral care).Results In single factor analysis,pulmonary underlying disease[infection group was 46.9％ (15/32),control group was 15.6％,(11/70),x2 =11.227,P =0.007],length of operation (≥ 180 min) [infection group was 62.5％ (20/32),control group was 31.4％ (22/70),x2 =8.753,P =0.041] and absence of postoperative oral care [infection group was 71.9％ (23/32),control group was 40.6％ (28/70),x2 =8.925,P =0.012] showed significant differences between two groups(P ＜ 0.05).After adjusting the effects of age,gender,diabetes and preoperative pulmonary function/blood gas,multinomial logistic regression showed that significant risk factors (P ＜ 0.05) included pulmonary underlying disease[infection group was 46.9％ (15/32),control group was 15.6％ (11/ 70),odds ratio (OR) =11.953,95％ confidence interval(CI):8.132-18.287],absence of temporarily prescribed antibiotics during operation[infection group was 81.2％ (26/32) ; control group was 59.4％ (42/70),OR =9.738,95％ CI:3.401-14.176] and absence of postoperative oral care[infection group was 71.9％ (23/32),control group was 40.6％ (28/70) ; OR =7.838,95 ％ CI:2.974-16.118].These factors were independent risk factors of hospital-acquired pneumoniaafter aseptic operation.Conclusion Examinations,antibiotics and regular oral care can reduce the incidence of hospital-acquired pneumonia after aseptic operation.
