研究目的:

本研究的主要目的是在拟行下肢关节置换术的老年患者中,探讨在侧卧位下蛛网膜下腔注射0.75%布比卡因复合芬太尼后,药物血药浓度变化与麻醉平面之间的内在关联。具体来说,研究旨在明确血药浓度变化是否与麻醉平面的形成时间、最高阻滞平面、麻醉效果持续时间等临床麻醉特征相关,为老年患者下肢关节置换术的个体化麻醉方案提供依据。  

Objectives of Study:

The main purpose of this study is to investigate the intrinsic relationship between changes in drug plasma concentration and the level of anesthesia in elderly patients undergoing lower limb joint replacement surgery in the lateral position after subarachnoid injection of 0.75% bupivacaine combined with fentanyl. Specifically, the study aims to clarify whether changes in plasma drug concentration are related to clinical anesthetic characteristics such as the onset time of the anesthetic level, the highest level of blockade, and the duration of anesthetic effect, providing a basis for individualized anesthesia regimens for elderly patients undergoing lower limb joint replacement surgery.
