A tourniquet with adequate pressure may prevent the spread of the venom into the circulation only if the extremity is immobilized by a cast and the patient does not walk, although there is no evidence from controlled studies.
Twenty-four volunteers had technetium-99m antimony-sulphur colloid injected subcutaneously or intracutaneously, mimicking a snake bite . Fifteen subjects had a tourniquet applied immediately after the injection. The tourniquet effectively prevented the spread of the substance if the pressure of the tourniquet was 40–70 mmHg in the upper extremity, and 55–70 mmHg in the lower extremity. Ten minutes of walking resulted in the spread of the substance into the circulation.
