Functional Evaluation of Skin Microcirculation at Endoexpander Use in Children

Results of laser doppler fluorometry and computer thermometry of skin at endoexpander use were analyzed in 30 children with injury sequelae, i.e. cicatrical deformities of soft tissues. It was shown that during expansion the skin vascularization increased and capillary component of hemodynamics activated. The utmost increase of microcirculation was noted during the first 2-3 weeks, especially in the projection of the endoexpander dome. The safe threshold of liquid volume injected into standard expander with capacity of 600 ml was 16.53.4 ml (single dose). In endoexpander the most acceptable control method for skin blood circulation was laser doppler fluorometry. In children skin expander did not aggravate microcirculation of cicatrical tissue and the bed of skin flap to be used that was favorable for flap survival.
