As a non-invasive technique for the measurement of blood and oxygen in tissue, the near-infrared spectroscopy (NIRS) has an increasing application to the postoperative monitoring of plastic surgery. In authorial research, a set of NIRS oximeter has been used in 6 successful flap-transplantation operations to monitor and contrast the oxygen saturation in the free flap side and in the normal opposite side. It was found in the research that there is a notable difference in the oxygen saturation between those two sides. Another research has been done in an unsuccessful operation. In this experiment, several points in the mandible were measured and the result shows that the oxygen saturation is at an obviously lower level in the anoxic position than in the normal ones. In the above several researches, near infrared spectroscopy showed a high sensitivity to detect the dynamic changes in flaps induced by inhalation of pure oxygen. Therefore, NIRS can be a valuable aid in the post-operative monitoring of free flap after the operation, and must have a great practical future in this field.
作为一种用于测量组织中血液和氧气的非侵入性技术，近红外光谱（NIRS）在整形外科术后监测中的应用越来越广泛。在作者的研究中，一套NIRS血氧仪已用于6例成功的皮瓣移植手术，以监测和对比游离皮瓣侧和正常对侧的氧饱和度。研究发现，这两侧的氧饱和度存在显著差异。另一项研究是在一次不成功的手术中进行的。在这个实验中，测量了下颌骨的几个点，结果表明，缺氧位置的氧饱和度明显低于正常位置。在上述几项研究中，近红外光谱显示出对吸入纯氧引起的皮瓣动态变化具有高灵敏度的检测能力。因此，NIRS可成为术后游离皮瓣监测的有价值辅助手段，并且在该领域必将有广阔的应用前景。
