背景
游离组织移植后早期发现血管损伤对防止皮瓣失败至关重要。近红外光谱显示了良好的承诺，监测皮瓣在深层次成功，而不是侵入性的。本研究的目的是测试INVOS 3100脑血氧仪是否能够检测循环障碍。
方法
在10名健康成人中，近红外光谱法用于测量止血带缺血和静脉流出限制期间的区域饱和值，在两个测试周期中。该探头包含一个红外线发射源和两个红外线传感器，被放置在肱桡肌上方手肘下方。使用Friedman检验和Wilcoxon-Wilcox检验对数据进行统计学比较。
结果
静脉和动脉闭塞的特征在于区域饱和度的瞬时下降。动脉闭塞显示饱和度值平均下降至28+/-9%，而静脉闭塞显示饱和度值平均下降至51+/-12%。与基线值相比，这些福尔斯在闭塞3分钟后显著下降（74+/-6%）。动脉和静脉闭塞之间的差异有统计学意义。
结论
本研究旨在测试较便宜的设备，能够测量绝对值，不易受探头移动引起的干扰，准确且无创地提供氧合曲线信息，并区分动脉和静脉闭塞。
BACKGROUND
Early detection of vascular impairments after free tissue transfers are essential to prevent flap failure. Near-infrared spectroscopy showed good promise to monitor flaps at deep levels successfully without being invasive. The purpose of this study was to test whether the INVOS 3100 cerebral oxymeter is capable of detecting circulatory impairments.
METHODS
In 10 healthy adults, near-infrared spectroscopy was used to measure regional saturation values during tourniquet ischemia and venous outflow restriction, in two test cycles. The probe, containing an infrared-light-emitting source and two infrared-light sensors, was placed below the elbow above the brachioradialis muscle. Statistical comparison of the data was performed using the Friedman test and the Wilcoxon-Wilcox test.
RESULTS
Venous and arterial occlusions were characterized by an instantaneous fall of the regional saturation. Arterial occlusion showed a mean decrease of the saturation values down to 28+/-9%, whereas venous occlusion showed a mean fall of saturation values down to 51+/-12%. These falls were significant after 3 minutes of occlusion compared with baseline values (74+/-6%). The differences between arterial and venous occlusions were statistically significant.
CONCLUSION
This study, designed to test less-expensive equipment, was able to measure absolute values, and was not prone to interference caused by probe movement, providing information on the oxygenation profile accurately and noninvasively, and distinguishing between arterial and venous occlusion.
