Appropriate tourniquet use in surgery: A literature review
Darcy Fay, Tayla Fay, Wayne Hoskins, Roger BinghamBackground:
Tourniquet use is ubiquitous in the operating theatre. However, optimal tourniquet usage is unclear, including type, pressure, inflation time, or whether a tourniquet should be used at all. This study reports a literature review of tourniquet use, comparing type, pressure, duration, effectiveness, and the spectrum of complications in an adult surgical population.
Results:
Data regarding population size, surgery performed, tourniquet type, tourniquet location, total tourniquet inflation time, timing of inflation and deflation, pressure, and complications were recorded. Postoperative tourniquet-related pain was the commonest adverse event. Other complications included venous thromboembolism, wound healing issues, neuropathy, and abrasions. Findings suggest that most surgeons use standardised pressures.
Conclusion:
Tourniquets are associated with a spectrum of complications. It is unclear whether tourniquet use provides better surgical outcomes. If tourniquets are used, surgeons should minimise the application pressure and duration. This may be achieved through a patient-centred approach and careful use of padding.
