Abstract：
Invasive arterial cannulation is a widely used method in intensive care units and operating rooms. However it has potential complications such as thrombosis, peripheral embolism, hematoma formation, and infection. The Masimo Root Radical-7 Pulse CO-Oximeter® (Masimo Corporation, Irvine, CA, USA) is a non-invasive hemodynamic monitoring device that measures perfusion index and pleth variability index, provides guidance to anaesthesiologists in the cases where hemodynamic fluctuations are expected. In this particular case, the perfusion index played a crucial role in the immediate diagnosis of radial artery embolism in a patient undergoing cytoreductive surgery and hyperthermic intraperitoneal chemotherapy procedure.
摘要：
有创动脉插管是重症监护病房和手术室中广泛使用的方法。然而，它有潜在的并发症，如血栓形成，外周栓塞,血肿形成,和感染。Masimo根自由基-7脉冲一氧化碳血氧仪®(MasimoCorporation，Irvine,CA,USA）是一种非侵入性血液动力学监测设备，可测量灌注指数和面积变异性指数，在预期血液动力学波动的情况下，为麻醉医师提供指导。在这种特殊情况下，在接受细胞减灭术和腹腔热灌注化疗的患者中，灌注指数在桡动脉栓塞的即时诊断中起着至关重要的作用。
