Arterial Tourniquets

Abstract

It is important to be aware of the physiological effects of tourniquets and the implications of this in anaesthesia as they may affect any system in the body.
There are no absolute contraindications to tourniquet use. However, care should be taken in high risk patients.
Tourniquet pain and tourniquet induced hypertension are very difficult to prevent and treat.
Pharmacokinetics of drugs can be altered during tourniquet use and antibiotic timing is very important in these patients.
Complications are rare, but if they occur, they can be devastating to patients.
Tourniquet inflation pressures and duration should be carefully monitored and it is the responsibility of everyone involved in patient care to ensure to be within recommendations.
Tourniquet safety checks should be carried out at regular intervals
