研究目的: |
1.分析腹围大小是否与低血压的发生风险存在显著关联。 2.确定腹围的预测价值:探索腹围是否可作为独立预测因子,或与其他已知风险因素(如体重指数、胎儿体重、麻醉平面等)结合提高预测准确性。 3.优化临床风险评估:为麻醉医师提供一种简便、无创的术前评估工具,以提前识别高风险患者并采取预防措施(如左侧倾斜体位、液体预负荷或血管活性药物使用) |
||||||||||||||||||||||
|
Objectives of Study: |
1. To analyze whether a significant association exists between abdominal circumference size and the risk of hypotension. 2. To determine the predictive value of abdominal circumference: specifically, to explore if it can serve as an independent predictor or, when combined with other known risk factors (such as Body Mass Index, fetal weight, level of anesthesia block, etc.), improve predictive accuracy. 3. To optimize clinical risk assessment: by providing anesthesiologists with a simple, non-invasive preoperative assessment tool to identify high-risk patients in advance and implement preventive measures (such as left uterine displacement, fluid preload, or the use of vasoactive drugs). |
