Types of tourniquets used

 

Makeshift tourniquets can be ropes, shoelaces, wire, leather, condoms or plastic bags. Some of these are not elastic enough for quick and easy release and may therefore cause trauma to the skin and veins and may cause infiltration of blood and fluids into surrounding tissues (Strike et al 2013). In addition, these items are often difficult to clean. It is recommended to use a tourniquet that is easy to release using one hand only.

Reuse and sharing of tourniquets

Observational studies have shown that tourniquets can be a potential source of exposition to blood borne pathogens (Crofts et al, 1999; Taylor et al 2004); In Scotland, 60% of the PWID have already shared their tourniquet (Scottish Drugs Forum and Glasgow Involvement Group, 2004). A tourniquet should not be used to stop the bleeding (may put the user at risk).


Risks associated to the sharing of tourniquets

Blood borne virus transmission

 

The risk associated to syringe sharing is much higher than the risk linked to tourniquet sharing. It is important to bear in mind though that, in hospital settings, Rourke et al (2001) found visible blood stains on 36% of the examined tourniquets; Golder et al (2000) found visible blood stains on half of them.

Other risks

Rourke et al (2001) have found Staphylococcus on 5% of the tourniquets tested in a hospital setting. Golder et al (2000) found abundant cutaneous flora on all samples and bacteria on 22% of the tourniquets.


Recommandations

  • Distribute tourniquets that are thin, flexible, easy to remove with a non-porous surface, without limiting the quantities supplied
  • Offer a tourniquet with each syringe
  • Educate clients about:
    • Bacterial and viral infections associated with the use of previously used tourniquets 
    • Tissue and vein damage, as well as circulatory problems that can be associated with the use of a non-quick-release-tourniquet
    • Adequate and individual tourniquet-use
