Abstract:
Objective To investigate the impact of nociceptive level(NOL)index on cellular immunity and HIF-1α in patients with radical breast cancer.Methods A total of 80 patients undergoing radical mastectomy between December 2022 and December 2023 were randomly assigned into an experimental group and a control group using a random number table method.The NOL index in the experimental group was maintained within the range of 30 to 50,with corresponding adjustments made to achieve the target concentration of remifentanil.In contrast,the control group initially received remifentanil at a target controlled infusion rate of 4 ng/mL,which was adjusted based on hemodynamics.The average target concentration of remifentanil was recorded for both groups.Venous blood samples were collected from all participants one day before and one day after surgery to measure CD4+,CD8+cell counts,NK cell activity,as well as serum levels of HIF-1α.Results There were no significant differences observed in anesthesia time,operation time,intraoperative mean arterial pressure(MAP),heart rate(HR),and postoperative visual analog scale(VAS)scores between the two groups.The average target concentra-tion of remifentanil in the experimental group was significantly lower than that in the control group(P＜0.05).Moreover,the experimental group exhibited higher values of CD4+,CD4+/CD8+ratio,and NK cells compared to the control group,while demonstrating a lower level of HIF-1α expression(P＜0.05).In addition,within the experimental group,there was a decrease in CD4+count and CD4+/CD8+ratio one day after surgery compared to one day before surgery;meanwhile,HIF-1α expression increased significantly after surgery when compared to preoperative levels(P＜0.05).Similarly,within the control group,there was a decrease observed in CD4+,CD8+,CD4+/CD8+ratio as well as NK cell values one day after surgery when compared to preoperative levels;additionally,HIF-1α expression showed a significant increase after surgery when compared to preoperative levels(P＜0.05).Conclusion The implementation of NOL monitoring during radical mastectomy under general anes-thesia can effectively lower the required remifentanil concentration,thereby mitigating its suppressive effects on T lymphocytes,preserving NK cell activity,and reducing elevated levels of HIF-1α.Consequently,this approach exerts minimal impact on the tumor immune microenvironment(TIME)in patients.
