The Allen's test for blood flow is performed before a forearm flap is elevated to examine vascularization through the ulnar artery. In this study, to ensure the survival of the donor site when a forearm flap was elevated, we monitored patients using a pulse oximeter. From oral cancer patients who were undergoing reconstructive surgery using the forearm flap, twenty patients were randomly selected to be served as subjects. A pulse oximeter probe was attached to the thumb on the side from which a skin flap was to be elevated. Oxygen saturation was measured when the tourniquet was released, and the radial artery was clamped and severed. The results showed that oxygen saturation temporarily decreased when the radial artery was ligated, but it recovered in one to two minutes.
在前臂皮瓣掀起前进行艾伦氏血流试验，以检查通过尺动脉的血管形成情况。在本研究中，为确保掀起前臂皮瓣时供区的存活，我们使用脉搏血氧计对患者进行监测。从接受前臂皮瓣重建手术的口腔癌患者中随机选取20例作为研究对象。将脉搏血氧计探头附着在要掀起皮瓣一侧的拇指上。在松开止血带、夹住并切断桡动脉时测量血氧饱和度。结果显示，结扎桡动脉时血氧饱和度暂时下降，但在1至2分钟内恢复。
