Effects of dezocine on cardiovascular response, stress response and cellular immune function before anesthesia induction in radical mastectomy for breast cancer

摘要

cqvip:Objective: To investigate the effects of dezocine on cardiovascular response, stress response and cellular immune function before anesthesia induction in radical mastectomy for breast cancer. Methods: From January 2014 to January 2018, 220 patients with breast cancer undergoing modified radical mastectomy were randomly divided into observation group (110 cases) and control group (110 cases). The observation group was given dezocine before induction of anesthesia, while the control group was given the same amount of Sodium Chloride Injection. Heart rate (HR), mean arterial pressure (MAP), blood oxygen saturation (SpO2), aldosterone (ALD), renin (REN), cortisol (Cor), angiotensin Ⅱ (Ang-Ⅱ) and the level of T cell subsets at 5 time points before anesthesia (T1), 2 h after operation (T2), 10 hours (T3), 24 h (T4) and 48 h (T5) after operation were compared between the two groups. Results:There was no significant difference in HR and MAP between the two groups before anesthesia (30 min). HR and MAP of the two groups were higher at 2 h after operation and 10 h after operation than before, and the HR and MAP of the control group were higher than those of the observation group. There was no significant difference in ALD, REN, Cor and Ang-Ⅱ between the two groups at 30 min before anesthesia and 48 h after operation. ALD, REN, Cor and Ang-Ⅱ in the two groups at 2 h after operation and 10 h, 24 h after operation were higher than those at the 30 min before anesthesia, and ALD, REN, Cor and Ang-Ⅱ in the control group were higher than those in the observation group. There was no significant difference in CD3+, CD4+, CD4+/ CD8+ between the two groups at 30 min before anesthesia and 48 h after operation. CD3+, CD4+, CD4+/CD8+ in the two groups at 2 h after operation and 10 h, 24 h after operation were lower than those at the 30 min before anesthesia, and CD3+, CD4+, CD4+/CD8+ in the control group were lower than those in the observation group. Conclusion: Dezocine before anesthesia induction in radical mastectomy can effectively reduce cardiovascular response and stress response, and play a protective role in cellular immune function.
