研究目的:

通过探讨右美托咪定鼻喷雾剂对异丙酚ED50的影响,旨在找到两者联合使用的最佳剂量组合,在保证充分镇静的同时,降低异丙酚用量,减少相关副作用,提高患者舒适度和安全性。并为右美托咪定鼻喷雾剂在胃镜检查中的应用提供科学依据。  

Objectives of Study:

By exploring the effect of dexmedetomidine nasal spray on propofol ED50, the aim is to find the optimal dose combination for the combined use of the two, ensuring adequate sedation while reducing the dosage of propofol, minimizing related side effects, and enhancing patient comfort and safety. And provide a scientific basis for the application of dexmedetomidine nasal spray in gastroscopy.

随机方法(请说明由何人用什么方法产生随机序列):

研究员使用计算机生成的随机序列对患者进行随机分组并分配编号,装在密闭不透明的信封里。另一名研究者打开信封并根据编号配备药物:右美托咪定1组(D1 组,右美托咪定+丙泊酚)注射 1.5 μg/kg右美托咪定经鼻喷注,右美托咪定2组(D2 组,右美托咪定+丙泊酚)注射 2.0 μg/kg右美托咪定经鼻喷注,对照组(C 组,生理盐水+丙泊酚)以相同方式给予注射等体积为 0.9% 生理盐水。药品上贴上编号。实施麻醉的麻醉医生、收集数据的研究者、护士、内镜医生、患者均不知道分组情况。

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

Researchers randomly grouped patients using computer-generated random sequences and assigned numbers, which were placed in sealed and opaque envelopes. Another researcher opened the envelope and dispensed the drugs according to the numbers: Dexmedetomidine Group 1 (Group D1, dexmedetomidine + propofol) was injected with 1.5 μg/kg of dexmedetomidine by nasal spray. Dexmedetomidine Group 2 (Group D2, dexmedetomidine + propofol) was injected with 2.0 μg/kg of dexmedetomidine by nasal spray. Control group (Group C) An equal volume of 0.9% normal saline was injected in the same way as normal saline and propofol. The medicine is labeled with a number. The anesthesiologists who performed the anesthesia, the researchers who collected the data, the nurses, the endoscopists, and the patients were all unaware of the grouping situation.
