Since its introduction in 1980, fiberoptic fluorometry has improved the precision and objectivity of the fluorescein test as a means to delineate nutritive blood flow and predict tissue viability. This study was undertaken primarily to determine if fiberoptic fluorometry could be repeated reliably at close time intervals. Four injections of fluorescein dye were administered at varying dose and time schedules to determine what factors influenced the repeatability of this technique. The results confirm the high accuracy of fluorometric indices as a means to predict the ultimate fate of a skin flap. A method of scanning the flap within 2 minutes after injection of 1.5 mg/kg of fluorescein dye correctly predicted the fate of almost 100% of flap sections. Repeated injections of 1.5, 3.0, and 6.0 mg/kg of dye at 15-minute intervals provided virtually identical predictions of flap viability. Thus fluorometry is readily repeatable and should be of value in assessing the state of tissue perfusion as well as changes in perfusion caused by pharmacologic manipulation or surgical intervention. |
