干预措施:

Interventions:

组别:

去甲肾上腺素组

样本量:

12

Group:

Norepinephrine group

Sample size:

干预措施:

颈动脉阻断前1min,静脉泵注NE 0.01~0.1μg/(kg.min),恒速泵入速度为0.1~10ml/h,阻断期间使MAP维持在高于基础血压的20%左右。血压维持不理想时,可单次静推4μg,必要时可重复使用。颈动脉开放时,停止去甲肾上腺素静脉输注。

干预措施代码:

Intervention:

One minute prior to carotid artery occlusion, norepinephrine (NE) was administered via intravenous infusion at a dose of 0.01–0.1 μg/(kg·min), with a constant infusion rate of 0.1–10 ml/h. During the occlusion period, mean arterial pressure (MAP) was maintained approximately 20% above baseline blood pressure. In cases where blood pressure control was suboptimal, a single intravenous bolus of 4 μg could be administered, which could be repeated as necessary. Upon reperfusion of the carotid artery, the intravenous infusion of norepinephrine was discontinued.

Intervention code:

组别:

去氧肾上腺素组

样本量:

12

Group:

Phenylephrine group

Sample size:

干预措施:

颈动脉阻断前1min,静脉泵注PE 0.1~0.6μg/(kg.min),恒速泵入速度为0.1~10ml/h,阻断期间使MAP维持在高于基础血压的20%左右。血压维持不理想时,可单次静推20μg,必要时可重复使用。颈动脉开放时,停止去氧肾上腺素静脉输注。

干预措施代码:

Intervention:

One minute prior to carotid artery occlusion, phenylephrine (PE) is administered via intravenous infusion at a dose of 0.1–0.6 μg/(kg·min), with a constant infusion rate of 0.1–10 ml/h. During the occlusion period, mean arterial pressure (MAP) is maintained approximately 20% above baseline blood pressure. In cases where blood pressure control is suboptimal, a single intravenous bolus of 20 μg may be administered and can be repeated if necessary. Upon reperfusion of the carotid artery, the intravenous infusion of phenylephrine is discontinued.

随机方法(请说明由何人用什么方法产生随机序列):

在随机对照双盲研究中,全麻下行颈动脉内膜剥脱患者60例(编号1~60),分为2组,一组去甲肾上腺素组,另一组为去氧肾上腺组。Excel中生成随机数字表,随机数字表任一行开始,按序查找,凡小于或等于60的数标记,查够30个数;将与这30个数对应编号患者列为去甲肾上腺素组,余下受试者为去氧肾上腺素组。

Randomization Procedure (please state who generates the random number sequence and by what method):

In a randomized, controlled, double-blind study, 60 patients undergoing carotid endarterectomy under general anesthesia (numbered 1 to 60) were randomly allocated into two groups: the norepinephrine group and the doxepin group. A random number table was generated in Excel, beginning with an arbitrary row of the table. Numbers less than or equal to 60 were sequentially identified and marked until 30 unique numbers were obtained. The patients corresponding to these 30 numbers were assigned to the norepinephrine group, while the remaining patients were assigned to the doxepin group.
