Single vs Double Eyelet Routing on a CAT Tourniquet.
In the 7th generation CAT tourniquet, the double eyelet was removed in favor of a perceived quicker single eyelet. Using the single routed eyelet for leg application requires reliance on only the velcro of the tourniquet band to hold pressure. If the Velcro fails or releases, the entire tourniquet would disengage with catastrophic results. More info on the blog.
Effective Clamshell Direct Pressure.
In our race to use tourniquets for controlling hemorrhage, we often lose sight of the value of good direct pressure as a hemorrhage control technique.
Proven commercially available tourniquets are almost always going to be better options for controlling significant extremity hemorrhage than direct pressure because tourniquets can be made “hands-free” once secured in place. Additionally, you can carry many more tourniquets than you have hands. However, dedicated medical equipment may not always be available and even when present, takes time to put into action. More on the blog.
Improvised Pediatric Pantleg Tourniquet (with doppler).
Our first plan is to use a proven commercially available tourniquet. Barring that, an improvised tourniquet using a cravat, or a strip of fabric, with a windlass for leverage. Given no other choices, you can may be able to use the casualty’s clothing with a rigid windlass, such as a metal pen, kitchen utensil, small tool, etc, to make a wearable improvised tourniquet. This is verified effective with doppler ultrasound. For more information on pediatric tourniquets generally, see the blog.
Improvised Adult Pantleg Tourniquet.
Having proven the improvised pant-leg tourniquet works on children via doppler ultrasound, Dr. Shertz demonstrates the technique on an adult. If no commercially available tourniquet is available, a successful tourniquet can be made using the casualty’s own clothing: Cut up the pants line including the seams, wrap the fabric around the limb, tie a square knot, and tighten with a windlass. *Ideally, the windlass should be secured with another strip of fabric. This video demonstrates an easy way to hold the windlass in place without an additional tie, but it could come loose during casualty movement.
Improvised Junctional Hemorrhage.
Thanks to Full Spectrum for coming up with a novel concept to deal with junctional hemorrhage using two CAT tourniquets and a helmet. We proved the concept today with doppler ultrasound. A creative solution to a difficult problem.
