Intermittent Pneumatic Compression (IPC) has been used successfully for theprevention of early postoperative deep vein thrombosis (DVT).Recently IPC hasbeen described for the treatment of lymphedema,chronic edema,recovery from lowerextremity ulcers and the enhancement of wound healing.For good applications of IPCin clinic,it is necessary to study its effective mechanism further.We measured 展开更多

The application of Intermittent Pneumatic Compression(IPC)is mainly assessedas a prophylaxis against postoperational deep vein thrombosis (DVT) abroad.It is al-so beneficial in the treatment of peripheral vessel diseases such as venous stasis,lymph stasis and so on.The effect of IPC on the prophylaxis against DVT is optimalcomparing with low-numerator dextran and heparin.The method hasn’t bleed ten-dency which the medicine has. 展开更多
