Abstract:
Objective:To study the effects of remimazolam on stress response index, T lymphocyte subsets and postoperative delirium in patients undergoing modified radical mastectomy.Methods:A total of 120 patients with breast cancer who underwent modified radical mastectomy in our hospital from Aug. 2024 to Dec. 2024 were separated into the control group (n=60, anesthetic induction and maintenance with Propofol) and the observation group (n=60, anesthetic induction and maintenance with remimazolam) according to random number table method, and the other anesthetic drugs were the same. The operation time, anesthesia recovery time, postoperative delirium and cognitive dysfunction of the two groups were observed, and the changes of stress response indexes and T lymphocyte subsets indexes at different time points were compared, and the adverse reactions after anesthesia were counted.Results:The incidence of postoperative delirium and cognitive dysfunction in the observation group was lower than that in the control group ( x2=4.62, 5.18, P < 0.05), and there was no statistically significant difference in operation time or anesthesia recovery time between the two groups ( t=0.43, 1.71, P > 0.05). The observation group had lower serum cortisol (Cor), norepinephrine (NE) and epinephrine (E) levels 30 min after anesthesia induction (T 1) and immediately after surgery (T 2) ( t=5.53, 6.71, 9.33, 6.74, 7.26, 8.77, P < 0.05), while the comparison of those indexes before surgery (T 0) and 12 h after surgery (T 3) showed no statistically significant difference ( t=1.19, 1.85, 0.90, 1.55, 1.64, 1.81, P > 0.05). The levels of CD3 +T, CD4 +T and CD4 +/CD8 + in the observation group were higher than those in the control group at T 1, T 2 and T 3 ( t=2.21, 4.94, 4.77, 4.44, 6.24, 7.07, 2.11, 2.56, 2.15, P < 0.05), and there was no statistically significant difference in those indexes between the two groups at T 0 ( t=0.76, 0.79, 1.51, P > 0.05). The incidence of adverse reactions after anesthesia showed no statistically significant difference between the two groups [25.00% (15/60) and 33.33% (20/60) ] ( χ2=1.008, P > 0.05) . Conclusion:The induction and maintenance of remimazolam anesthesia can effectively reduce the incidence of postoperative delirium and cognitive dysfunction in patients with modified radical mastectomy, relieve the body stress response of patients, and effectively reduce the influence of anesthesia on T lymphocytes.
