Validity of laser Doppler flowmetry for measuring the effect of the tissue expander pressure on skin circulation. Simultaneous measurement of tissue pressure and laser Doppler flowmetry.
Intermittent Laser Doppler Flowmetry (LDF) was used in five patients to measure changes in the dermal blood flow when changing intraluminal pressures in tissue expanders (TE). In another patient, continuous monitoring of the intraluminal pressure in the TE and simultaneous LDF was used. Our finding is that LDF is a suitable method for the registration of reactions in dermal circulation, caused by TE pressure changes. A statistically significant association between the changes of the LDF values and the intraluminal pressure in the TE was observed.
