title: [Hemodynamics of the acute random skin flap and methods for monitoring its viability. An experimental study].
abstract: The haemodynamics and affecting factors of the acute random skin flap and the methods for monitoring its viability were studied. 28 male Japanese white rabbits were used. The standardized random skin flaps were used. The standardized random skin flaps were formed on the back of rabbits. The three methods for monitoring the changes of the haemodynamics of the flaps were: 99mTc clearance, fluorescein test and photoplethysmography. The results showed: the most obvious changes of the flap occurred in the first 24 hours after operation. The period was crucial for its surviving length. There were significant differences between the proximal region of the flap and its distal region. Reserpine increased not only the nutrient blood flow of the flap, but also its surviving length. The three methods for monitoring the viability of the flap were analysed and their values were discussed.
