[The effects of electric copper needle on venous thrombosis in the rat].

OBJECTIVE

In order to study the relation between the electric copper needle and venous thrombosis in the rat.

METHODS

90 rats were divided into two groups, each using either the superficial epigastric vein or the femoral vein for the experiment. The relations of voltage, current, electrifying time and venous thrombosis were studied and the histological changes were observed.

RESULTS

1. 1.4 V DC did not damage the vessel-nerve. 2. The current declined with time to 0.1 mA. 3. When the diameters of the copper needle and the vein were similar (P > 0.05), the thrombogenesis time was from 5.5 to 10.5 minutes. When the diameters of the copper needle and the vein were different (P < 0.05), the thrombogenesis time was from 7.5 to 17.5 minutes.

CONCLUSIONS

For the electric copper needle to get ideal treatment, the best voltage is 4 V DC for 5.5 to 10.5 minutes or 7.5 to 17.5 minutes.
