It is possible to link a Laser-Doppler to a DOS-compatible personal computer in order to monitor microcirculation of the free flap after plastic surgery. We connected such a system to a second computer by telephone modems, in order to control the Laser-Doppler via the telephone line from a distant location using only commercially available hardware and software. The aim was to develop a low-cost system which would not require the purchase or construction of any specialised equipment. Using this system, it was possible to show the Laser-Doppler waveforms to colleagues who were not at the patient site, for their (more experienced) opinions without any further delays. Preliminary tests on five cases showed that it was indeed possible to transfer recorded information about the blood flow rate of free skin flaps from one computer to a remote one, without any loss of information. In these cases, the measured blood flow and clinical surveillance of the blood supply were adequate, thus making revision of the tissues not necessary. This preliminary study suggests that standard 'off-the-shelf' personal computer tools may be useful in improving the monitoring of microcirculation after plastic surgery.
为了监测整形手术后游离皮瓣的微循环，可以将激光多普勒仪与兼容DOS的个人计算机相连。我们通过电话调制解调器将这样一个系统连接到另一台计算机上，以便仅使用市售的硬件和软件，通过电话线从远处控制激光多普勒仪。目的是开发一种低成本系统，该系统无需购买或构建任何专门设备。使用该系统，可以将激光多普勒波形展示给不在患者现场的同事，以便他们（更有经验）发表意见，而不会有任何进一步的延迟。对5例患者的初步测试表明，确实可以将记录的游离皮瓣血流速度信息从一台计算机传输到远程计算机，且不会有任何信息丢失。在这些病例中，测量的血流情况和对血供的临床监测是足够的，因此无需对组织进行修复。这项初步研究表明，标准的“现成”个人计算机工具可能有助于改善整形手术后的微循环监测。
