研究目的: |
目前间羟胺用于预防老年患者全麻诱导期间低血压的剂量-反应关系尚未完全明确,因此,本研究旨在基于体重确定固定速率输注间羟胺用于预防老年患者全麻诱导期间低血压的中位有效剂量(ED50)和90%有效剂量(ED90)。 |
||||||||||||||||||||||
|
Objectives of Study: |
The dose-response relationship of metaraminol for preventing hypotension during general anesthesia induction in elderly patients remains undefined. This study aims to determine the median effective dose (ED50) and 90% effective dose (ED90) of a weight-based, fixed-rate infusion of metaraminol for this purpose. |
