Analysis Of Risk Factors For Esophageal Postoperative Respiratory Failure

Objective:To explore the risk factors of postoperative respiratory failure ofesophagectomy. Methods:49postoperative respiratory failure of esophagectomy caseswere collected in our hospital from Sep2002to Sep2009,98patients withoutpostoperative respiratory failure of esophagectomy were extracted randomly on1:2ratioduring the same period as controls. χ2test and logistic regression analysis were used toanalyze the risk factors. Result:Univariate analysis results show that the following factorsrelated to the postoperative respiratory failure of esophagectomy: Maximum voluntaryventilation(MVV), first second forced expiratory volume (FEV1), peak expiratory flow(PEF), first second forced expiratory volume/forced vital capacity (FEV1/FVC), smokingindex, operative duration, time of mechanicalventilation, preoperative respiratory disease,the anastomotic location and other complications after surgery. Logistic regressionanalysis showed that: first second forced expiratory volume (FEV1)≤1.5L, maximumvoluntary ventilation (MVV) measured/predicted value of≤50%, postoperativecomplications and operative duration≥3hours were the independent risk factors.Conclusion: Comprehensive assessment and improvement of preoperative pulmonaryfunction, improving surgical techniques and minimize operative duration, closelypostoperative observation to reduce the incidence of other complications were theimportant factors to reduce the postoperative respiratory failure of esophagectomy.
