Abstract:
Objective To analyze the application of dexmedetomidine in intracranial arterial stenting and its influence on the serum myocardial enzyme ,cardiac troponin I(cTnI) and left ventricular ejection fraction (LVEF). Methods From March 2015 to March 2017,94 cases with intracranial arterial stenting in the People's Hospital of Lishui were divided into control group and observation group by the random number table method ,with 47 cases in each group.The control group was treated with conventional anesthesia ,the observation group was treated with dexme-detomidine.The enzyme creatine phosphate kinase isoenzyme (CK -MB),creatine phosphate kinase (CK),cTnI, LVEF,inflammatory factor, neural function, brain oxygen metabolism and complications in the two groups were compared.Results After surgery,the CK-MB,CK,cTnI levels of the observation group were lower than those of the control group[(35.27 ±4.41) U/L,(488.30 ±61.03) U/L,(3.85 ±0.49) μg/L vs.(46.40 ±5.79) U/L, (611.21 ±76.40)U/L,(4.72 ±0.59)μg/L],the LVEF of the observation group was higher than that of the control group[(45.60 ±5.72)%vs.(43.12 ±5.39)%],the differences were statistically significant (t＝10.484,8.619, 7.777,2.163,all P＜0.05).The interleukin -6(IL-6) and interleukin -8(IL-8),tumor necrosis factor -α (TNF-α),S-100β,specificity enolization enzyme(NSE),cerebral metabolic rate of oxygen(ERO2),arterial blood oxygen saturation(PaO2),carotid venous blood oxygen saturation (SjvO2) of the observation group were better than those of the control group(t＝5.794,6.177,15.065,6.964,5.606,3.147,2.116,2.807,all P＜0.05).The inci-dence rate of complication of the observation group was lower than that of the control group (χ2＝17.091,P＜0.05). Conclusion Application of dexmedetomidine in intracranial arterial stenting can protect myocardium , inhibit the serum levels of myocardial enzyme ,cTnI rise,and is conducive to the recovery of LVEF.
