Near infrared spectroscopy is a relatively new technique for monitoring intracerebral oxygen saturation. Using the technique, three episodes of cerebral hypoxia were detected during elective carotid endarterectomy which were not reliably recorded by more standard monitoring of cerebral perfusion. In one case, cerebral hypoxia was related to slippage of the tracheal tube into the right main bronchus and in the other two to episodes of hypotension. Near infrared spectroscopy is a reliable indicator of peripheral cortical perfusion and provides continuous and noninvasive monitoring of intracerebral oxygen saturation.
近红外光谱技术是一种用于监测脑内氧饱和度的相对较新的技术。使用该技术，在择期颈动脉内膜切除术中检测到三次脑缺氧发作，而通过更标准的脑灌注监测未能可靠记录这些发作。在一个病例中，脑缺氧与气管导管滑入右主支气管有关，在另外两个病例中与低血压发作有关。近红外光谱技术是外周皮质灌注的可靠指标，可对脑内氧饱和度进行连续无创监测。
