The influence of anesthetic method on the immune function and oxidative stress in patients receiving laparoscopic herniorrhaphy remains largely unknown.

To assess the effects of different anesthetic methods on the immune function and oxidative stress in patients undergoing laparoscopic herniorrhaphy.

A total of 280 eligible patients were randomly divided into two groups to receive total intravenous anesthesia (TIVA group) and inhalation anesthesia (IA group). T lymphocyte subsets, oxidative stress response indices and inflammatory factor levels were measured before anesthesia, at the end of the operation, and 1 and 3 days after the operation. The incidence rates of adverse reactions were compared.

At the end of and 1 day after the operation, CD3⁺ and CD4⁺ T cells and CD4⁺/CD8⁺ decreased in both groups compared with those before anesthesia (p < 0.05). Three days after the operation, CD3⁺ and CD4⁺ T cells decreased in both groups compared with those before anesthesia, which were higher in the TIVA group (p < 0.05). Interleukin-6 and C-reactive protein levels were significantly lower in the TIVA group (p < 0.05). At the end of and 1 and 3 days after the operation, oxidative stress response indices superoxide dismutase, catalase and glutathione peroxidase declined in both groups compared with those before anesthesia, which were higher in the IA group (p < 0.05). The incidence rate of adverse reactions was significantly higher in the IA group (p = 0.002).

Compared with IA, TIVA has less effect on the immune function and oxidative stress of patients undergoing laparoscopic herniorrhaphy, and controls the inflammatory response more effectively, accompanied by a lower incidence rate of adverse reactions.
