研究目的:

本研究旨在通过随机对照研究探讨被动抬腿后颈动脉血流校正时间变化率(PLR-ΔFTc)在预防老年胃肠手术患者麻醉诱导后低血压(PIH)的应用价值。第一部分通过观察确立PLR-ΔFTc预测PIH的界值。第二部分通过随机对照试验验证基于该界值的目标导向补液在降低PIH的临床有效性。  

Objectives of Study:

This study aims to investigate, through a randomized controlled trial, the value of the rate of change of carotid artery corrected flow time after passive leg raising (PLR-ΔFTc) in preventing post-induction hypotension (PIH) in elderly patients undergoing gastrointestinal surgery. The first part establishes the cutoff value of PLR-ΔFTc for predicting PIH through observation. The second part validates the clinical effectiveness of goal-directed fluid therapy based on this cutoff value in reducing PIH through a randomized controlled trial.
