The effect of dexmedetomidine combined with nicardipine on the controlled hypotension and inflammatory factors in elderly patients undergoing spinal surgery

Objective To discuss the effect of dexmedetomidine combined with nicardipine on the controlled hypotension and inflammatory factors in elderly patients undergoing spinal surgery.Methods 100 elderly patients undergoing spinal surgery(ASA physical statusⅠ-Ⅱ)in our hospital from June 2017 to June 2019 were selected,there were 56 males and 44 females with an age of(70±6)years,and they divided into dexmedetomidine combined with nicardipine group(D+N group)and nicardipine group(N group),50 minutes before anesthesia(T₁),10 minutes after operation(T₂),20 minutes after operation(T₃),30 minutes after operation(T₄),drug withdrawal(T₅),and at the end of operation(T₆)and the inflammatory factors such as interleukin-6(IL-6),tumor necrosis factor-alpha(TNF-alpha),C-reactive protein(CRP)at before operation and 2h,6h after operation and operative field definition,intraoperative blood loss,adverse reactions were recorded.Results The HR[(78.5±5.8)times/min,(80.3±5.7)times/min,(81.6±5.9)times/min,(81.8±6.12)times/min,(80.1±8.6)times/min],MAP[(58.2±3.3)mmHg,(58.8±3.5)mmHg,(59.1±3.5)mmHg,(84.1±6.6)mm Hg,(83.1±6.2)mm Hg]and CVP[(4.0±0.5)cm H₂O,(4.1±0.5)cm H₂O,(4.2±0.5)cm H₂O,(5.2±0.5)cm H₂O,(5.1±0.5)cm H₂O]in the D+N group at T₂,T₃,T₄,T₅,T₆were significantly lower than those in the N group[(85.6±6.5)times/min,(88.1±6.7)times/min,(89.3±6.9)times/min,(88.7±6.57)times/min,(86.4±6.4)times/min,(62.2±3.5)mm Hg,(63.3±3.5)mm Hg,(63.6±3.8)mm Hg,(92.6±6.4)mm Hg,(90.2±6.2)mm Hg,(4.7±0.5)cm H₂O,(4.9±0.5)cm H₂O,(5.0±0.5)cm H₂O,(7.1±0.7)cm H₂O,(6.6±0.7)cm H₂O],the difference was statistically significant(F=58.462,F=72.428,F=76.921;F=167.562,F=204.382,F=257.691;all P<0.05).The operative field definition score(2.1±0.3),intraoperative blood loss[(392±71)ml]in the D+N group were significantly lower than those in the N group[2.6±0.3,(684±95)ml],the difference was statistically significant(t=8.333,t=17.331,P<0.05).The levels of IL-6[(182.5±20.3)pg/ml,(253.6±30.2)pg/ml],TNF-alpha[(35.7±4.0)ng/ml,(44.4±5.7)ng/ml]and CRP[(27.2±2.2)mg/L,(42.1±5.0)mg/L]in the D+N group at 2 and 6h after operation were significantly lower than those in the N group[(214.3±25.7)pg/ml,(342.4±36.1)pg/ml,(41.5±4.7)ng/ml,(56.4±6.2)ng/ml,(34.3±2.7)mg/L,(58.4±6.4)mg/L],the difference was statistically significant(F=64.871,F=82.653,F=93.254;F=94.268,F=125.436,F=151.367;F=74.216,F=90.843,F=98.630;P<0.05).The incidence of adverse reactions(10.0%)in the D+N group was significantly lower than that in the N group(30.0%),the difference was statistically significant(χ²=6.250,P<0.05).Conclusions Dexmedetomidine combined with nicardipine can effectively improve the controlled hypotensive effect of elderly patients undergoing spinal surgery,it is helpful to improve the hemodynamics and operative field definition of patients,and it can reduce the inflammatory stress reaction and adverse reactions after surgery,it’s worth for further clinical promotion.
