It has been suggested that direct monitoring of arterial temperature using implanted thermocouples, may have value as a clinical postoperative monitor for vascularized free tissue transfers, including those with no visible surfaces. This study evaluated the technique in experimental animals, using simple, inexpensive equipment. Mean arterial differential temperature changes, with ipsilateral (n = 20) and contralateral (n = 21) references, of 0.6 degrees C and 0.5 degrees C respectively, reliably indicated occlusion of the superficial femoral artery in situ. In epigastric island flaps, arterial occlusion (n = 24) produced mean arterial temperature changes of 0.5 degrees C, but changes after venous occlusion were not significantly greater than unoccluded base line fluctuation. Venous differential temperature did not change significantly after either arterial or venous occlusion. In six epigastric free flaps, success or failure could not be distinguished, as the wide variation in measurements in the four successful flaps overlapped the recordings in the two which failed. It was shown that the nearer to the body core, the less the temperature difference between arterial wall and periarterial tissue. Occlusion of deeply sited arteries produced little or no change in arterial temperature. In view of these findings and because of the invasive nature of the technique, the authors did not pursue it clinically.
有人提出，使用植入式热电偶直接监测动脉温度，对于血管化游离组织移植术后的临床监测可能具有价值，包括那些没有可见表面的移植组织。本研究使用简单、廉价的设备在实验动物中评估了该技术。分别以同侧（n = 20）和对侧（n = 21）为参照，平均动脉温差变化分别为0.6摄氏度和0.5摄氏度，可靠地表明原位股浅动脉闭塞。在腹壁岛状皮瓣中，动脉闭塞（n = 24）导致平均动脉温度变化0.5摄氏度，但静脉闭塞后的变化并不显著大于未闭塞时的基线波动。动脉或静脉闭塞后，静脉温差均无显著变化。在六个腹壁游离皮瓣中，无法区分成功或失败，因为四个成功皮瓣测量值的广泛变化与两个失败皮瓣的记录重叠。结果表明，离身体核心越近，动脉壁与动脉周围组织之间的温差越小。深部动脉闭塞对动脉温度几乎没有影响或没有影响。鉴于这些发现以及该技术的侵入性，作者没有在临床上继续应用。
