Tourniquet application has been widely accepted to improve survival for major limb trauma. Colour duplex ultrasound (US) can be used as a non-invasive method of confirming cessation of arterial flow. Participants with no or limited experience of ultrasound were taught to apply the Combat Application Tourniquet with ultrasound guidance. ⋯ No significant difference was found in application time for the lower limb; less time was taken for application with US guidance in the upper limb 8.1 (7.1, 8.6) vs 4.5 s (4.0, 5.3; median (IQR)), p=0.002. Tourniquet ultrasound skills are rapidly acquired by novice operators. Accuracy improves with ultrasound guidance, this may have a role in improving survival.
