较高剂量的雷米芬坦尼尔在全身麻醉诱导过程中没有显著改变静脉压 (SAP). 这项研究发现,当Remifentanil与Propofol结合使用时,没有剂量依赖的血液动力学影响.
科学领域:
- 麻醉学 麻醉学
- 心血管生理学心血管生理学
背景情况:
- 在用普罗波福尔诱导全身麻醉期间,雷米芬坦尼尔的血液动力学效应可能与剂量有关.
- 系统性动脉血压 (SAP) 是血液动力学稳定的关键指标.
研究的目的:
- 调查增加雷米芬坦尼尔剂量是否会导致在普罗波福尔诱导全身麻醉期间SAP的更大降低.
- 评估Remifentanil在血液动力学参数上的剂量反应关系.
主要方法:
- 一项随机,双盲,剂量控制的研究,涉及99名接受妇科手术的健康女性.
- 参与者接受了低剂量,中剂量或高剂量的雷米芬坦尼尔 (Ce 2,4,8 ng/mL) 与固定剂量的普罗波 (Ce 2.9 μg/mL).
- 节奏对节奏的血液动力学监测 (LiDCOplus) 用于测量SAP后玻尿酸剂的最大降低.
主要成果:
- 在低剂量,中剂量和高剂量雷米芬坦尼尔组之间没有观察到SAP绝对或相对变化的统计学上显著差异.
- 差异分析 (ANOVA) 显示绝对SAP变化的p值为0.29,相对SAP变化的p值为0.52.
- 血液动力学参数包括心率,中风量,心脏输出和全身血管阻力也没有显著的群体间差异.
结论:
- 虽然在麻醉诱导期间发生了显著的血液动力学变化,但增加雷米芬坦尼尔剂量并没有导致SAP减少的统计学上显著差异.
- 持续的入侵性节奏对节奏监测没有揭示在本研究群体中雷米芬坦尼尔的剂量依赖的血液动力学效应.
