研究概览
详细说明
禁食 6 小时后,每位志愿者将在桡动脉放置一根 20G 的动脉导管用于早期采血,并在对侧前臂放置一根 18G 的外周静脉导管用于药物给药和后期采血。 持续监测的生命体征将包括记录的 ECG、有创血压、血红蛋白、O2 饱和度、呼气末 CO2 和呼吸频率(来自二氧化碳描记图)。
在获取基线 PD 数据后,将通过自由流动的外周静脉注射 (t=0) 在 10 秒内推注 0.2 mg/kg 氢吗啡酮,并在 0.25、0.5、0.75、1、 1.25、1.5、1.75 和 2 分钟,使用旋塞阀和歧管系统。 随后的血液样本将在 3、4、5、7.5、10、15、20、25、30 和 45 分钟以及 1、1.25、1.5、2、2.25、2.5、2.75、3、3.5、4、4.5 时采集、5、6、7、8、10、12、16、20 和 24 小时。 尽管 EEG 将连续获取,但其余药理学数据将在最初 5 分钟的离散时间 s 上记录:1、2 和 5 分钟的瞳孔测量;通风 2 分钟; 3 分钟和 5 分钟的温度镇痛,以及 4 分钟的镇静水平。 这将允许在静息状态下获得通气和瞳孔测量,从而限制刺激对这些反应的扭曲。 随后,将按以下顺序在所有 PK 时间点获取所有数据 - 通气和脑电图(同时)、瞳孔测量、修改后的 OAA/S 评分和温度镇痛。 2 小时后,一旦药理学参数返回基线进行 2 次连续测量,该参数的记录将停止。 在研究期间,如果志愿者由于阿片类药物引起的镇静而无法使用设备触发器,则温度升高的耐受水平将定义为志愿者表现出测试肢体缩回运动时的温度。 完成所有数据采集后,将允许志愿者饮用清澈的液体。 随后,将在耐受的情况下推进饮食。 志愿者将在临床研究室每小时接受一次监测(生命体征),直到采集完所有血样。
