The fiberoptic fluorometer permits quantitative measurement of fluorescence after intravenous administration of fluorescein. Accurate assessment of tissue fluorescence can be made at any time after the injection, and both uptake and elimination of fluorescein can be followed. The instrument provides instantaneous digital readout of the fluorescence measured in dye fluorescence (DF) units and an index predictive of viability called the dye fluorescence index (DFI). The unit is portable, can be sterilized for operating room use, and can be operated by paramedical personnel with ease. We have used the instrument extensively in clinical and laboratory investigations, where it has been highly reliable in predicting survival and necrosis of a wide variety of flaps. Little or no operating time is added, and serial, low-dose fluorescein injections may be used to monitor a flap in the recovery room or at the bedside in the early postoperative period.
光纤荧光计可在静脉注射荧光素后对荧光进行定量测量。注射后任何时间均可对组织荧光进行准确评估，且可追踪荧光素的摄取和消除情况。该仪器能以染料荧光（DF）单位即时数字显示所测荧光，并提供一个名为染料荧光指数（DFI）的预测活力指标。该仪器便于携带，可进行消毒以供手术室使用，辅助医务人员也能轻松操作。我们已在临床和实验室研究中广泛使用该仪器，它在预测各种皮瓣的存活和坏死情况方面一直非常可靠。几乎不增加手术时间，术后早期可在恢复室或床边通过连续低剂量注射荧光素来监测皮瓣。
