Abstract
OBJECTIVES: We aimed to compare the effects of general anesthesia with combined epidural and general anesthesia in patients with early-stage non-small cell lung carcinoma (NSCLC). METHODS: Patients scheduled to undergo tumor resection with adjuvant chemoradiotherapy were eligible. Patients in the control group received general anesthesia during surgery, and those in the observation group received combined epidural and general anesthesia. The hemodynamic factors mean arterial pressure (MAP), heart rate, end-tidal carbon dioxide, and oxygen saturation were measured. Serum levels of pro-inflammatory cytokines interleukin (IL)-1, IL-8, high-sensitivity C-reactive protein (hs-CRP), and tumor necrosis factor (TNF)-α as well as β-endorphin were measured by enzyme-linked immunosorbent assay. Serum malondialdehyde (MDA) was measured using the thiobarbituric acid method. RESULTS: The incidence of specific adverse events was reduced and overall and disease-free survival were improved in the observation group compared with the control group. MAP was generally lower in the observation group compared with the control group, as were the serum levels of IL-1, IL-8, hs-CRP, TNF-α, and MDA. CONCLUSIONS: Compared with general anesthesia, combined epidural and general anesthesia may inhibit the occurrence of short-term adverse events and improve long-term outcomes by inhibiting inflammatory responses in patients with early-stage NSCLC after tumor resection.
