    AbstractThe objective of this study is to compare the effects of paravertebral nerve block-propofol intravenous general anesthesia (PPA) and sevoflurane inhalation general anesthesia (SGA) on the expression of serum vascular endothelial growth factor (VEGF) and transforming growth factor beta (TGF-β) in patients undergoing radical resection of lung cancer.Patients undergoing radical resection of lung cancer were divided into PPA group and SGA group. In PPA group, thoracic paraspinal nerve block was performed with 0.5% ropivacaine (2 mg/kg) before general anesthesia. Anesthesia was maintained with 2.5-3.5 μg/mL TCI of propofol. In SGA group, anesthesia was maintained with 1.0-1.5 MAC sevoflurane. The dosage of opioids during and 24 h after operation, the pain score at 2, 8, 24, 48, and 72 h after operation, and the concentrations of serum VEGF and TGF-β before and 24 h after operation were observed in the two groups.The intraoperative dosage of remifentanil in PPA group was significantly less than that in SGA group (P < 0.05). The dosage of sufentanil in SGA group was significantly less than that in SGA group at 24 h after operation (P < 0.05). The VAS score at 2, 8, and 24 h after operation was significantly lower than that in SGA group (P < 0.05). The serum VEGF and TGF-β concentration in PPA group was significantly lower than that in SGA group (P < 0.05).Thoracic paravertebral nerve block-propofol intravenous general anesthesia can reduce the dosage of opioids, improve the effect of postoperative analgesia, and reduce the serum concentration of tumor angiogenesis-related factors in patients undergoing radical resection of lung cancer.
