At the January meeting of the Western Section of the Triological Society, Drs Goding and Cummings and Mr Trachy presented the results of their work measuring the effects of controlled skin expansion on blood flow. Cutaneous blood flow was measured by a dermofluorometer in 28 subcutaneous pockets placed in seven pigs, which were divided into three groups. The first group underwent expansion of the subcutaneous pocket with a 200-mL tissue expander over 12 days, followed by deflation and observation for an additional six days. The second group had a noninflated 200-mL tissue expander placed, and the third group served as a control. In group 1 there was no significant change in blood flow prior to skin expansion. Inflation of the expander on the fourth day resulted in decreased blood flow with return of that flow at the time of second expansion on the eighth day, and overall increase in flow
