Another ancient technique used to limit blood loss is ligation, where a piece of thread or wire called a suture is tied around a blood vessel to seal it. The traditional 16th century method for sealing limbs after amputation was to use a combination of boiling oil and cauterization.

He used a tincture made of turpentine which limited infection , egg yolk and oil of roses on the soldiers who still needed treatment. He found that the soldiers who had been treated with the traditional method were still in agony, but those that were treated with his tincture were doing much better.

The evidence from this impromptu field trial persuaded him to use ligatures to tie off large blood vessels such as arteries. But ligatures were not without problems. They tended to infect the wound, so they were not widely adopted by other surgeons.

The tourniquet was another 16th century method to control blood loss during amputation. This was a device or piece of material secured around a limb in order to limit the blood flowing down into the rest of the limb. The difference between a tourniquet and a ligature was that the tourniquet was used to temporarily stop the flow of blood, whereas the ligature was more permanent.

Joseph Lister also recommended elevating the limb before using a tourniquet to make the surgical opening as blood-free as possible. In , Harvey Cushing created a pneumatic tourniquet, which compressed the underlying blood vessels by inflating a cylindrical bladder. This type of tourniquet could be applied and removed quickly and it decreased the incidence of nerve paralysis caused by depriving the blood vessels of blood for too long.

Tourniquets are still used to keep the field of operation free from blood. None of these techniques was of much help if there had already been extensive blood loss. Over the centuries several attempts were made to replenish the blood supply, either with animal or human blood, but they generally failed. Skip Navigation.
