[Experimental study on relieving blood stasis of skin flaps using leeches].

Isolated congested flaps in lower abdomen of rats were treated by application a method of sucking blood with medical leeches. The results were shown that survival rate of sucking blood group was 93.9%, non-sucking blood group was only 14.3% and small incision bleeding group in which incision was rinsed by Heparin-physiological saline was 25%. It has proved that this method has a very good effect on relieving blood stasis of tissue. We think that this method can be put to use clinically.
