Abstract:
Objective To explore the incidence rates of lower respiratory tract infections after general anes-thesia in the elderly orthopedics patients and to analyze the related risk factors.Methods A total of 45 patients with lower respiratory tract infections in 479 elderly orthope -dics patients who received general anesthesia were enrolled in the study.The bacterial identification and drug susceptibility testing were preformed after the collection of sputum specimens.The univariate factor analysis and multivariate logistic regression analysis were performed to identify the risk factors for the lower respiratory tract infections after general anesthesia,including the age,gender,smoking histo-ry,chronic respiratory diseases history,basic cardiovascular disease,diabetes,mental disease,and endotracheal tube type,anesthesia ventilation time,postoperative extubation time,and postoperative analgesia.Results Smoking history (Wald =5.058,OR =4.618),chronic respiratory diseases history(Wald =37.950,OR =20.507),mental disease (Wald =26.303,OR =75.644),endotrac heal tube type(Wald =9.035,OR =11.758),anesthesia(Wald =15.035, OR =20.163)and postoperative extubation time(Wald =14.243,OR =12.613)were identified as the risk factors for lower respiratory tract infections after general anesthesia in the elderly orthopedics patients (all P <0.05 ). Conclusion Risk factors should be intervened in elderly orthopedics patients who receive general anesthesia,and the antibiotics should be chosen on the basia of the drug susceptibility testing.
