Abstract:
Objective:To observe the application effect of dexmedetomidine in brain tumor resection surgery.Methods:60 patients who underwent brain tumor resection surgery in our hospital from September 2023 to September 2024 were selected,the patients were randomly divided into reference group(conventional anesthesia,n=30)and experimental group(reference group combined with dexmedetomidine,n=30)used random number table method.Neuron specific enolase(NSE),blood glucose,hemodynamic indicators[mean arterial pressure(MAP)and heart rate(HR)]between the two groups were compared,the recovery time,intraoperative opioid use,sedative level,extubation time,and occurrence of adverse reactions between the two groups were observed.Results:Compared with the time point of intubation(T1),MAP in the reference group decreased sequentially from the time point of beginning of surgery(T2)to the time point of skull drilling(T3)(P＜0.05).Compared with the end of surgery(T5),the MAP at time point of after returning to the intensive care unit(T6)in the reference group increased(P＜0.05).MAP in the experimental group decreased sequentially from the time point of before anesthesia induction(T0)to T2(P＜0.05).Compared with the time point of T5,MAP in the experimental group at time point of T6 increased(P＜0.05).MAP in the experimental group at time points of T1-T3 and T6 was lower than that in the reference group(P＜0.05).HR in the reference group at time points of T0～T2 first increased and then decreased(P＜0.05),Compared with HR at time point of T5,HR at time point of T6 in the reference group increased(P＜0.05).Compared with the time point of T1,HR in the experimental group decreased first and then increased from the time point of T2 to T3(P＜0.05).Compared with HR at time point of T5,HR at time point of T6 in the experimental group increased(P＜0.05).HR in the experimental group at time points of T1 to after tumor resection(T4)and T6 were lower than those in the reference group(P＜0.05).NSE levels increased in both groups at time points of T5,but the experimental group was lower than that in the control group(P＜0.05).Compared with the blood glucose at time point of T0 in the same group,the blood glucose at time point of T5 in the reference group increased,while the blood glucose at time point of T5 in the experimental group decreased,and the blood glucose at time point of T5 in the experimental group was lower than that in the reference group(P＜0.05).There was no significant difference in the recovery time,extubation time,and postoperative Ramsay score between the two groups(P＞0.05),but the dosage of remifentanil in the experimental group was lower than that in the reference group(P＜0.05).The overall incidence of adverse reactions in the experimental group was lower than that in the reference group(P＜0.05).Conclusion:The application of dexmedetomidine in patients undergoing brain tumor resection surgery can stabilize the hemodynamics of patients,inhibit the stress response,and significantly reduce the dosage of remifentanil and the risk of adverse reactions.It has good sedative effect and safety.
