Abstract

|
|
Many experimental studies have demonstrated beneficial effect of electrical field application to various hard and soft tissues.
The present study was undertaken to determine if application of exogenous electric fields could improve survival rate of random pattern skin flap in rats.
32 Spraque-Dawley rats were divided into 4 groups and caudally based random pattern flaps of 2 x8cm in size were elevated in all experimental animals. Silver electrodes were implanted into the fascia to apply the electrical stimulation(-5V, 0.2ms, 20hz) to the skin flap.
Electrical stimulation was applied 3 times for 1 hour daily and it was continued to the 5th day.
It is concluded that exogenous electrical stimulation shows a possibility of the enhancement of flap survival rates by increasing the rates to 32 %(P(0.01).
