干预措施:

Interventions:

组别:

瑞马唑仑组

样本量:

55

Group:

R group

Sample size:

干预措施:

在麻醉诱导前静脉泵注瑞马唑仑0.2 mg/kg,随后使用依托咪酯(0.1~0.3 mg/kg)、舒芬太尼(0.3~0.5 μg/kg)、罗库溴铵(0.6 mg/kg)进行麻醉诱导,麻醉维持使用瑞芬太尼0.1~0.3 μg/kg·min、丙泊酚4~6mg/kg·h,瑞马唑仑0.5 mg/kg·h进行持续泵注,并吸入七氟烷(0.5~1% MAC)。术中间断追加罗库溴铵(每次0. 2 mg/kg)维持肌肉松弛,维持BIS值在40~60之间。

干预措施代码:

Intervention:

Before anesthesia induction, remimazolam was intravenously pumped at a dose of 0.2 mg/kg. Then, anesthesia induction was performed using etomidate (0.1-0.3 mg/kg), sufentanil (0.3-0.5 μg/kg), and rocuronium (0.6 mg/kg). For anesthesia maintenance, remifentanil (0.1-0.3 μg/kg·min), propofol (4-6 mg/kg·h), and remimazolam (0.5 mg/kg·h) were continuously pumped, and sevoflurane (0.5-1% MAC) was inhaled. During the operation, rocuronium was intermittently added (0.2 mg/kg each time) to maintain muscle relaxation, and the BIS value was maintained between 40 and 60.

Intervention code:

组别:

右美托咪定组

样本量:

55

Group:

D group

Sample size:

干预措施:

在麻醉诱导前静脉泵注右美托咪定0.5 ug/kg,随后的麻醉诱导与瑞马唑仑组相同。麻醉维持时将右美托咪定泵注速率调整为0.2 ug/kg·h。

干预措施代码:

Intervention:

Dexmedetomidine was intravenously pumped at a dose of 0.5 μg/kg before anesthesia induction, and the subsequent anesthesia induction was the same as that in the remimazolam group. During anesthesia maintenance, the pumping rate of dexmedetomidine was adjusted to 0.2 μg/kg·h.

Intervention code:

组别:

生理盐水组

样本量:

55

Group:

C group

Sample size:

干预措施:

在麻醉诱导及维持时静脉泵注等量生理盐水。

干预措施代码:

Intervention:

An equal amount of normal saline was intravenously pumped during induction and maintenance of anesthesia.

随机方法(请说明由何人用什么方法产生随机序列):

一名不参与观察和数据处理的麻醉医生根据计算机生成的随机序列以1∶1∶1的比例将所有患者分为3组(n=55):瑞马唑仑组(R组)、右美托咪定组(D组)和生理盐水组(C组),并按顺序对应装入标记顺序号的不透明信封,序列号由该麻醉医生保管。受试者经筛选合格后通知该麻醉医生按顺序发放序列号给麻醉护士,麻醉护士使用20ml注射器将R组的瑞马唑仑和D组的右美托咪定配置成20ml,C组抽取等容积的生理盐水,并在注射器上贴上标注有患者序列号的标签。麻醉诱导和维持时,三组均以相同的速率泵注。

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

An anesthesiologist who did not participate in observation and data processing divided all patients into 3 groups in a 1:1:1 ratio (n=55) according to a computer-generated random sequence: the remimazolam group (Group R), the dexmedetomidine group (Group D), and the normal saline group (Group C). The medications corresponding to each group were put into opaque envelopes marked with serial numbers in order, and the serial numbers were kept by this anesthesiologist. After the subjects were screened and qualified, the anesthesiologist was notified to issue the serial numbers to the anesthetic nurse in order. The anesthetic nurse used a 20ml syringe to prepare 20ml of remimazolam for Group R and 20ml of dexmedetomidine for Group D, and drew an equal volume of normal saline for Group C. A label with the patient's serial number was affixed to the syringe. During induction and maintenance of anesthesia, all three groups were infused at the same rate.
