Abstract：Objective To investigate the effect of high,middle and low dose dexmedetomidine combined with sufentanil on perioperative analgesia and sleep quality in patients with oral cancer.Methods A total of 158 patients undergoing oral cancer surgery in the hospital from January 2023 to June 2024 were selected and divided into group A[n=53,0.6 μg/(kg h)dexmedetomidine+2 μg/kg sufentanil]and group B[n=53,0.4 μg/(kg h)dexmedetomidine+2 μg/kg sufentanil],Group C[n=52,0.2μg/(kg·h)dexmedetomidine+2 μg/kg sufentanil]by random number table method.Stress response indexes[brain-derived neurotrophic factor(BDNF),cortisol(Cor),interleukin-6(IL-6)],bifrequency index and analgcsia nociccption index(BIS,ANI),pain level,T lym-phocyte subsets CD3+,CD4+,CD8+levels,Richards Campbell Sleep Scale(RCSQ)score and adverse reactions were compared between the two groups.Results Compared with 12 h before surgery,serum levels of BDNF,Cor and IL-6 in 3 groups were decreased 48 h after surgery,group A was lower than group B,group C,group B was lower than group C(P＜0.05).Compared with T0,BIS at T1～T3 were significantly different between the 3 groups(P＜0.05),BIS at T1～T3 were lower than those at T0(P＜0.05),and there was no significant difference in BIS at the same time between the 3 groups(P＞0.05),from T,to T3,ANI was higher than that at T0,and ANI in group A was higher than that in group B and group C(P＜0.05).Compared with the preoperative results,the pain scores of the 3 groups were decreased at 1 h,6 h,24 h and 48 h after operation,and the pain scores of group A were lower than those of group B and C,and the pain scores of group B were lower than those of group C(P＜0.05).After operation,CD3+and CD4+were decreased in all 3 groups,group A was lower than group B and group C,group B was lower than group C(P＜0.05),and CD8+was increased in all 3 groups,group A was higher than group B and group C,group B was higher than group C(P＜0.05).Compared with 1 day before the operation,the sleep quality scores of the three groups on the night after the operation and the second night after the operation were all decreased,group A was lower than group B and group C,and group B was lower than group C(P＜0.05).The incidence of hypotension and sinus bradycardia in group A was higher than that in group B and group C(P＜0.05).There was no significant difference in the incidence of hypotension and sinus bradycardia between group B and group C(P＞0.05).There was no significant difference in the incidence of nausea,vomiting and dizziness among the three groups(P＞0.05).Conclusion The analgesic effect of 0.6 μg/(kg·h)dose dexmedetomidine com-bined with sufentanil can effectively reduce the body's stress response and immune suppression,improve sleep quality,but with a greater incidence of intraoperative hypotension and bradycardia.
