What is the maximum length of time the tourniquet can be used?
The tourniquet applied must ultimately be strong enough
to squeeze the arteries close to the bone. However, the
blood must not be squeezed for too long, as this can lead to
fatal consequences - such as damage to blood vessels, nerves
or muscles. It is therefore essential that the start of the tourniquet application is noted on the
tourniquet so that this information is available for
further treatment. The use of a tourniquet is only a temporary measure in every
case. In most cases, the
tourniquet is necessary until further surgical treatment of the
injury is possible.
However, it is perfectly possible to leave the
tourniquet in place for up to two hours without
any consequences. For example, tourniquets
are ideal for bridging the gap between
initial treatment and surgical treatment for patients who are bleeding heavily.
However, it should be checked at regular intervals whether the
tourniquet is still effective and fulfils its purpose - if necessary,
the toggle should be retightened.
