The history of tourniquet use in limb surgery

As tourniquets have been present in medicine since almost its conception, understanding and following their development through time is not only an exercise in history but also an insight into the evolution of medical devices over more than two millennia. From simple leather bands wrapped around patients' limbs to the modernised digital devices used widely in surgical theatres globally, tourniquets have undergone tectonic change both in their design and application, moving from battlefields to hospitals. Hence, the aim of this article is to outline the historical development of these devices alongside their present and modern use.

The historical development of emergency and surgical tourniquets is chronologically outlined, with particular emphasis on the impact of warfare on their widespread adoption in trauma and emergency medicine and elective surgery. Novel surgical trends and their impact on the future of tourniquet use are evaluated.

The development of tourniquets across two millennia has closely reflected both the scientific understanding of human physiology and anatomy as well as technological discoveries and advancements that have reshaped their design and application. Prominent figures in the field of surgery, such as Sushruta, Fabricius Hildanus, John Louis Petit, Joseph Lister, Harvey Cushing and James McEwen, all fundamentally influenced their evolution and helped popularise and modernise them. The views on their use have been controversial and drastically changed across different eras, with data collected from modern warfare serving to embed their use in clinical practice.

The historical development of tourniquets since pre-historic times represents an excellent outline of the adaptive nature of medicine, led, firstly, by scientific rigour and discipline and, secondly, by pioneers who serve as catalysts for change and improvement. The modern inflatable cuff tourniquets that are omnipresent in theatres globally will undoubtedly remain the standard of care for the foreseeable future. Tourniquets that can dynamically monitor blood pressure and consequently adjust inflation pressures, as well as ones with inbuilt axonal excitability monitoring, will further improve their safety profile, reduce associated complication rates and represent the next step in the evolution of these devices. Notably, there might be a shift away from tourniquet use altogether, reflected by the wide use of the wide-awake local anaesthesia no-tourniquet technique that has become the new norm in hand surgery.
