Effect of dexmedetomidine on stress response and inflammatory reaction of patients with hysterectomy / 中国生化药物杂志

ABSTRACT

Objective To study the effect of dexmedetomidine on stress response and inflammatory reaction of patients with hysterectomy.Methods 96 patients with hysterectomy who received therapy from October 2014 to October 2016 in Jinhua traditional Chinese medicine hospital were selected.According to random number table,those patients were divided into the observation group(n=48)and the control group(n=48).Two groups were treated with total intravenous anesthesia,the observation group was treated with intravenous infusion of dexmedetomidine1μg·kg-1 before anesthesia,pump is completed within 15 minutes,then continuous injection of 0.5μg·kg-1·h-1 speed to the 30min before the end of the operation; the control group was given the same way of infusion of normal saline.The operation time,blood loss,recovery time,extubation time and length of stay were recorded,and the hanges of mean arterial pressure(MAP),heart rate(HR),hydrogen peroxide(H2O2),malondialdehyde(MDA),total antioxidant status(TAS),tumor necrosis factor(TNF)-α,interferon(IFN)-γ,interleukin(IL)-10 at T0(before anesthesia),T1(at the end of pneumoperitoneum),T2(after the end of pneumoperitoneum 30min),T3(postoperative 24h)were recorded.Results There was no significant difference between the two groups in operation time,blood loss,recovery time,extubation time and length of stay; in the control group,the MAP was significantly reduce at T1,T2 was significantly higher,the HR was significantly reduce at T1(P<0.05); there was no significant change of MAP and HR levels in the observation group at each time point; the H2O2 and MDA in the observation group were lower than that of the control group at T1,T2 and T3,and the TAS was higher than that of the control group(P<0.05); the TNF-α,IFN-γ and IL-10 in the observation group were lower than that of the control group at T1,T2 and T3(P<0.05).Conclusion Intravenous infusion of dexmedetomidine before anesthesia is well for patients with hysterectomy,it'is helpful to maintain the hemodynamic stability,and effectively alleviate the stress response,inflammation reaction,it's worth promoting.
