The effect of perfusion on post-operative viability in the replanted rabbit ear: measured by laser Doppler flowmetry and skin temperature.
The effect of perfusion by heparinized Ringer solution on post-operative microcirculation in rabbit ear replants was studied. One ear in each of five rabbits was replanted after perfusion with heparinized Ringer solution and these were compared with five replantations of rabbit ears without perfusion. The ears were studied post-operatively for 2 1/2 days by skin temperature monitoring and Laser Doppler Flowmetry (LDF). During the first day after replantation the perfused ears had better capillary flow, whereafter no significant differences were noted. LDF was more sensitive to changes in capillary blood flow, and this seems to make the reproducibility of LDF poor. It is, however, a suitable method for continued observation of post-operative viability.
