Abstract: The hemodynamic effect of general anesthesia on the venous velocity of the lower limbs was investigated in 20 patients who volunteered to undergo venous compression with the use of a new pneumatic device, the Venopress. Venous velocity in the common femoral vein was monitored by a duplex device before and after induction of general anesthesia. Results indicated that prior to general anesthesia, venous velocity was increased two- to fourfold by the Venopress and when anesthesia was induced, a further augmentation of 10 to 30% was achieved. We conclude that, the Venopress is a very efficient device for venous velocity augmentation, especially during general anesthesia.
