Objective To investigate risk factors of postoperative pulmonary complications(PPCs)in children after video-assisted thoracoscopic lung resection.Methods Retrospective analysis of clinical data of 566 children,334 males and 232 females,aged≤6 years,ASA physical statusⅠorⅡ,enrolled for video-assisted thoracoscopic lung resection.The children were divided into two groups based on whether they developed PPCs within 7 days after surgery:the PPCs group and the non-PPCs group.Factors with P≤0.2 and perceived as potentially clinically meaningful,were included in the binary logistic regression model.The receiver operating characteristic(ROC)curve was drawn and the area under the curve(AUC)was calculated.Results A total of 123 children(21.7%)developed postoperative pulmonary compli-cations(PPCs).Multivariate logistic regression analysis showed longer duration of one-lung ventilation(OLV),faster respiratory rate during OLV and inexperienced surgeon were found to be independently risk factors of PPCs.Higher PEEP level was protective factors of PPCs(The maximum PEEP was 7 cmH2 O).The prediction model was Logit(P)=-4.41+0.006×OLV duration+0.063×OLV respiratory rate+0.569×inexperienced surgeon(yes = 1)-0.16×maximum PEEP value.The ROC curve showed a good accuracy with an area under the curve of 0.682(95%CI 0.631-0.734),and sensitivity was76.4%,and specificity was 69.6%.Conclusion Longer OLV duration,faster repiratory rate and less surgeon experience are found to be independently risk factors of PPCs.Higher PEEP level is protective factor of PPCs.
