The correlation analysis and predictive value of peak expiratory flow on pulmonary infection after esophageal carcinoma operation / 中华胸心血管外科杂志

ABSTRACT

Objective To investigate the correlation between perioperative risk factors including pulmonary fuction indexs and the occurance of postoperative pneumonia in esophageal carcinoma patients,and the prediction efficiency of Peak Expiratory Flow (PEF).Methods Two groups of consecutive esophageal carcinoma patients were included,321 patients in group 1 were devided into postoperative pneumonia group (n =30) and control group (n =291) to screen any relavent risk factom on postoperative pneumonia;group 2 (n =50) was to verify the accurancy and sensitivity of the predictive index.Results he results from group 1 showed that preoperative history of diabetes,previous surgery history,lung function index FEV1 and PEF in the presence of significant differences between the postoperative pneumonia group and the control group,after FDR correction FEV1 and PEF still have statistical significance.Multivariate logistic analysis showed that PEF was an independent prognostic factor of lung infection after esophageal cancer surgery.We build a predictive model with PEF as a variable index of lung infection after esophageal cancer surgery in group 2,the results showed that PEF as a predictor of pulmonary infection has good specificity and sensitivity.Conclusion PEF has a significant correlation with postoperative pulmonary infection in patients with esophageal cancer,and PEF can be used as an effective predictor of postoperative pulmonary infection.
