摘要 : 目的: 观察依托咪酯与咪达唑仑用于老年患者在麻醉诱导期对于无创心排量的影响。方法: 收集60个病例,ASA分级I~Ⅱ级全身麻醉手术患者,开放外周静脉,随机分为依托咪酯 (A)、咪达唑仑 (B)两组,A组用依托咪酯诱导,剂量为0.15mg/kg,复合靶控输注瑞芬太尼;B组用咪达唑仑诱导,剂量为0.1mg/kg同样复合靶控输注瑞芬太尼,观察记录诱导前(T0),诱导后(T1)与插管即刻(T2)、插管后1min(T3)、插管后3min(T4)的平均动脉压(MAP)、心率(HR)、心排血量(C0)、心排指数(CI)及外周阻力(SVR)。结果: 依托咪酯组 T1、 T2、 T3、T4时的MAP、HR、CO、CI、SVR与诱导前相比,差异无统计学意义;咪达唑仑组T1、 T2、 T3、T4时的MAP、HR、CO、CI、SVR与诱导前相比差异有统计学意义。结论: 依托咪酯全身麻醉诱导后对老年患者血流动力学的影响与咪达唑仑相比较为平稳。

Abstract: 0bjective To observe the older patients cardiovascular responses to the inducement of Remifentanil combined respectively with midazolam andetomidate.Method Total 60 ASA grade I~II patients with gener anesthesia and open outer vein were selected and randomly divided into groups of etomidate (group A)and midazolam(group B).Group A received TCI of Remifentanil and intravenou injection of etomidat; group B received TCI of remifentanil and intravenou injection of midazolam. A monitor was used to observe and record MAP,HR,CO,CI, and SVR separetedly at the time before anesthesia induction, the time after anesthesia induction, the time at intubation tube point,the time after intubation tube 1 and 3 min.Results There was no significant changes of MAP,HR,CO,CI, and SVR in group A before and after the anesthesia induction (P>0.05),while in group B there was a significant decrease of MAP,HR,CO,CI, and SVR after the anesthesia inducement(P<0.05).Conclusion The inducement of etomidat gener anesthesia has smooth and steady effect on the elderlys blood flow dynamics than midazolam.

現今已步入老年社会,随着社会的进步,老年人的寿命进一步延长,老年人的疾病亦变得相当复杂,老年患者的麻醉现今已不可避免成为焦点。人类的器官功能随着年龄的增加而不断退化,麻醉耐受力也慢慢变差,迫使医者不断深入研究麻醉药物对于重要器官的作用。本次观察将比较依托咪酯与咪达唑仑对于老年患者心血管系统的影响。
1.资料与方法
1.1一般资料 选择60例患者,年龄在60~80岁,男女不拘,ASA分级在1~2级,拟参加全身麻醉的患者参加本研究,男女各30例,随机分为依托咪酯组与咪达唑仑组。两组患者性别、年龄、体重等一般情况差别无显著性,具有可比性。所……
