目的:研究右美托咪定(dexmedtomidine,DEX)对高血压患者手术麻醉诱导过程中循环功能的影响。方法选择40例行脊柱手术麻醉的高血压患者, ASAⅡ-Ⅲ级,随机分为两组(n=40):右美托咪定组(D组,n=20)和生理盐水对照组(N组,n=20),对照组按常规诱导麻醉,右美托咪定组在麻醉诱导前,使用右美托咪定0.5μg/kg在10分钟内泵入,接着持续用0.5μg/kg/h,记录基础值(T0)、生理盐水对照和右美托咪啶注射后(T1)、插管前(T2)及气管内插管后1min(T3),3min(T4),5min(T5)时的血压和心率。结果 N组MAP、SAP及DAP在插管前(T2)与基础值(T0)相比下降、在气管插管后1min(T3)、3min (T4),与基础值相比都升高,差异有统计学意义(P<0.05)。D组血压波动不明显,两组间比较差异有统计学意义。试验组的心率,在右美托咪定注射后与对照组相比明显降低,有统计学差异(P<0.05)。结论右美托咪定可以有效的抑制由于麻醉诱导和气管插管所导致的心血管反应,稳定循环功能。
目的:研究右美託咪定(dexmedtomidine,DEX)對高血壓患者手術痳醉誘導過程中循環功能的影響。方法選擇40例行脊柱手術痳醉的高血壓患者, ASAⅡ-Ⅲ級,隨機分為兩組(n=40):右美託咪定組(D組,n=20)和生理鹽水對照組(N組,n=20),對照組按常規誘導痳醉,右美託咪定組在痳醉誘導前,使用右美託咪定0.5μg/kg在10分鐘內泵入,接著持續用0.5μg/kg/h,記錄基礎值(T0)、生理鹽水對照和右美託咪啶註射後(T1)、插管前(T2)及氣管內插管後1min(T3),3min(T4),5min(T5)時的血壓和心率。結果 N組MAP、SAP及DAP在插管前(T2)與基礎值(T0)相比下降、在氣管插管後1min(T3)、3min (T4),與基礎值相比都升高,差異有統計學意義(P<0.05)。D組血壓波動不明顯,兩組間比較差異有統計學意義。試驗組的心率,在右美託咪定註射後與對照組相比明顯降低,有統計學差異(P<0.05)。結論右美託咪定可以有效的抑製由于痳醉誘導和氣管插管所導緻的心血管反應,穩定循環功能。

Objective: To investigate the effects of demedetomidine premedication on the circulation in patients with hypertension during anesthetic induction and tracheal intubation. Methods: Forty patients with hypertension scheduled for spinal surgery were enrol ed in this study. Patients were randomized into two group (n=20 each):group C=control; group D=dexmedetomidine. Dexmedetomidine (0.5ug/kg) were administered to patients in group D by a infusion pump 10min prior to anesthetic induction. While patients in group C received the same volume normal saline. The infusion lasted 10 min. BP( Blood pressure)HR(heart rate)were respectively recorded at the fol owing time points, before infusion of dexmedetomidine (T0), immediately before tracheal intubation(Tl),1, 3, 5 min after tracheal intubation(T2-5).Results: Compared with T0,In group N,BP were significantly decreased at T1 then increased at T3 and T4(P<0.05) .These variables had no significant change in group D. Statistical y significant differences were found between the two groups(P<0.05).The level of HR was significantly lower at Tl-5 than that at T0 in group D, Statistical y significant differences were found between the two groups(P<0.05). Conclusion: Dexmedetomidine premedication can safely and effectively al eviate the cardiovascular response and keep the stability of circulation in patients with hypertension during anesthetic induction and tracheal intubation.
