研究目的:

比较减重手术患者在麻醉恢复室拔管后,采用不同半卧位角度(15° vs. 30° vs. 45°)10分钟内低氧血症(SpO2≤90%)的发生率,探索最佳半卧角度对氧合功能的保护作用。  

Objectives of Study:

To compare the incidence of hypoxemia (SpO2 <= 90%) within 10 minutes after extubation in the anesthesia recovery room among patients undergoing weight loss surgery who were placed in different semi-recumbent positions (15°, 30°, and 45°), and to explore the protective effect of the optimal semi-recumbent position angle on oxygenation function.

随机方法(请说明由何人用什么方法产生随机序列):

由独立统计师使用 Excel 2021 RAND() 函数生成 447 个 0–447之间随机小数,按从小到大排序后,1-149号为“15°半卧位组”,149-298号为“30°半卧位组”,298-447号为“45°半卧位组”,随机序列保存于加密 U 盘。随机序列打印后装入连续编号、不透光、无标识信封内;信封由统计师封存于专柜,受试者入室后由麻醉护士按顺序拆封,拆封过程双人照相留痕 。

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

An independent statistician generated 447 random decimal numbers between 0 and 447 using the Excel 2021 RAND() function. After sorting them in ascending order, numbers 1-149 were assigned to the "15° semi-reclining position group", numbers 149-298 to the "30° semi-reclining position group", and numbers 298-447 to the "45° semi-reclining position group". The random sequence was saved on an encrypted USB drive. The random sequence was printed and placed in consecutively numbered, opaque, unmarked envelopes; the envelopes were sealed by the statistician in a designated cabinet. After the subjects entered the room, the anesthesiologist unsealed the envelopes in order, and the unsealing process was photographed by two people for record-keeping.
