干预措施:

组别:

艾司氯胺酮治疗组

样本量:

Group:

Esketamine Treatment Group

Sample size:

干预措施:

中度CRBD患者,采用Dixon上下自序分配方法(以0.025 mg/kg为步长)决定治疗剂量。第一位患者使用0.15 mg/kg艾司氯胺酮治疗,加入100 ml盐水,并在10分钟内静脉输注完毕。如果治疗有效,下一位患者艾司氯胺酮剂量减少0.025 mg/kg;如果治疗无效,则比前一位患者增加0.025 mg/kg。艾司氯胺酮给药后60分钟重新评估CRBD的严重程度。

干预措施代码:

Intervention:

For patients with moderate CRBD, the treatment dose was determined using the Dixon up-and-down sequential allocation method with a step size of 0.025 mg/kg. The first patient received 0.15 mg/kg of esketamine. This dose was diluted in 100 ml of saline and intravenously infused over 10 minutes. If the treatment was effective, the esketamine dose for the subsequent patient was decreased by 0.025 mg/kg. If the treatment was ineffective, the dose was increased by 0.025 mg/kg compared to the previous patient. The severity of CRBD was reassessed 60 minutes after esketamine administration.
