BackgroundVideo-assisted thoracoscopic surgery has been widely used in thoracic surgery worldwide. Our goal was to identify the risk factors for postoperative pneumonia in patients undergoing video-assisted thoracoscopic surgery lobectomy.MethodsA retrospective analysis of adult patients undergoing video-assisted thoracoscopic surgery lobectomy between 2016 and 05 and 2017-04 was performed. We used univariate analyses and multivariate analyses to examine risk factors for postoperative pneumonia after lobectomy.ResultsThe incidence of postoperative pneumonia was 19.7% (n = 143/727). Patients with postoperative pneumonia had a higher postoperative length of stay and total hospital care costs when compared to those without postoperative pneumonia. Multivariate analysis showed that body mass index grading ≥24.0 kg/m2 (vs. <24.0 kg/m2: odds ratio 1.904, 95% confidence interval 1.294-2.802, P = 0.001) and right lung lobe surgery (vs. left lung lobe surgery: odds ratio 1.836, 95% confidence interval 1.216-2.771, P = 0.004) were independent risk factors of postoperative pneumonia. Total intravenous crystalloid infusion grading in the postoperative 24 h ≥ 1500 mL was also identified as the risk factors (vs. 1000 to < 1500 mL: odds ratio 2.060, 95% confidence interval 1.302-3.260, P = 0.002).ConclusionsMajor risk factors for postoperative pneumonia following video-assisted thoracoscopic surgery lobectomy are body mass index grading ≥24.0 kg/m2, right lung lobe surgery and total intravenous crystalloid infusion grading in the postoperative 24 h ≥ 1500 mL.
