Abstract
Our aim was to determine if a tourniquet placed on the ankle has any advantage in forefoot surgery over the position on the midcalf. We randomised 30 patients who were undergoing forefoot surgery under under local anaesthesia into two groups. One had a tourniquet on the ankle and the other on the mid calf. All calf and ankle tourniquets were inflated to 100 mm Hg above the systolic pressure, just before the surgical procedure.
The blood pressure, pulse and level of pain were recorded at intervals of five minutes during the operation. The surgeon evaluated the quality of the anaesthesia, the bloodless field, and the site of the tourniquet.
The patients tolerated the tourniquet on the ankle much more. Both the tourniquet positions gave good operative fields, however the use of the ankle tourniquet was less painful at 5,10,20 and 30 minutes after the operation had started (p< 0.01). Physiological parameters were better in the ankle group.
We conclude that the ankle tourniquet gives a good bloodless field and provides improved pain tolerance for forefoot surgery carried out under local anaesthesia.
