Abstract:

Objective

to explore the analysis of factors affecting the occurrence of complications after lung cancer surgery.

Methods

The clinical data of 68 patients who underwent thoracoscopic general anesthesia for radical lung cancer treatment in the hospital from January 2023 to December 2023 were retrospectively analyzed，and the postoperative complications of thoracoscopic general anesthesia for radical lung cancer were evaluated by using unifactorial and multifactorial logistic regression analysis.

Results

In the observation group，there were 11 cases （52.38%） with ASA grade Ⅲ，19 cases with hypotension （90.48%），19 cases with diabetes （90.48%），19 cases with stroke （90.48%），17 cases with CHD （80.95%） and 19 cases with age≥70 years （There were 19 cases （90.48%） with FEV1%≤60% and 18 cases （85.71%） with DLCO%≥80%，compared with 8 cases （17.02%） with ASA grade Ⅲin the control group，27 cases with hypotension（57.45%） and 22 cases with diabetes mellitus （46.81%）. There were 28 cases （49.57%） of FEV₁≥1.5 L，30 cases （63.83%） of FEV1%≤60% and 29 cases （61.70%） of DLCO%≥80%，and there was no statistical significance （P ＜0.05）. ASA grade Ⅲ，hypotension，diabetes，stroke，CHD，age，FEV₁，FEV1% and DLCO% were the influencing factors of postoperative complications of lung cancer （P ＜0.05）. Multivariate Logistic regression analysis showed that age≥70 years old （OR=1.054，95% CI：1.012～1.119），CHD （OR=1.354，95% CI：1.159～1.629），FEV₁%≤60% （or：1）.

Conclusion

Age≥70 years old，CHD and FEV1%≤60% are the risk factors of complications after thoracoscopic lung cancer radical surgery.
