Assessment of microsphere technique for measurement of capillary blood flow in random skin flaps in pigs.
In this technical paper, we reviewed the theory and methodology of the radioactive microsphere technique for determination of cardiac output and regional blood flow. Furthermore, we described two experiments conducted to assess this technique for measurement of capillary blood flow in skin-flap research. Our experimental data thus far indicated that the radioactive microsphere technique provided highly reproducible measurements for determination of capillary blood flow in 4 X 10 cm acute and delayed random skin flaps constructed in pigs. The advantages and disadvantages of this laboratory technique were also discussed.
