Treatment of superficial thrombophlebitis. A comparative trial between placebo, Hirudoid cream and piroxicam gel.

A prospective randomized trial on the treatment of superficial thrombophlebitis has been performed in 68 patients randomized to either Hirudoid cream, piroxicam gel or placebo. Both spontaneous and infusion thrombophlebitis were included. Treatment effect was evaluated using the status of thrombophlebitis, the thrombophlebitic area, pain intensity with a visual analogue scale, and side effects were registered. Both in the treatment groups and the placebo group there was a significant decrease of signs and symptoms during the treatment period. There was no statistical difference between the treatment groups and no difference between spontaneous and infusion thrombophlebitis.
