概括

预诱导外周 perfusion 指数 (PPI) 不能预测后诱导低血压 (PIH) 在一个大手术队列. 已确定的风险因素,如血压和年龄,对于评估PIH风险更可靠.

科学领域:

麻醉学麻醉学
心血管生理学心血管生理学
手术风险评估手术风险评估

背景情况:

诱导后低血压 (PIH) 是一般麻醉的常见并发症.
以前的研究表明,外周 perfusion 指数 (PPI) 可以预测PIH,但有局限性.
这项研究旨在验证PPI在大量手术患者群体中的预测价值.

研究的目的:

评估诱导前外周 perfusion 指数 (PPI) 对诱导后低血压 (PIH) 的预测性能.
为了比较PPI的预测能力与大型手术队列中已确定的风险因素.

主要方法:

对6653名接受全身麻醉的成年患者的回顾性分析.
PIH定义为平均动脉压 < 65 mmHg 在诱导后 20 分钟内.
用于评估PPI预测性能的接收器运行特征曲线 (AUC) 下的面积.

主要成果:

整体PIH发生率为51.5%.
诱导前的PPI显示PIH的预测性表现不佳 (AUC为0.51).
已经确定的因素,如预诱导平均动脉压,晚年和紧急手术是PIH的独立预测因素.

结论:

预诱导PPI在一大批手术患者中对PIH没有显著的预测价值.
麻醉师应依靠已确定的风险因素进行PIH风险评估.
周围输液指数不是诱导后低血压的可靠预测指标.
