Ray Castle: The focus, as you see here, will be on in looking at the effectiveness of tourniquets in managing mass hemorrhage injuries. We'll briefly cover types and limitations of various types of commercial available turnkey kits.
04:17
There is a lot of debate on whether and how providers and late personnel estimate actual blood loss. There's a lack of evidence supporting consistency in how we visual estimation of blood.
08:30
About 400 or 500 mass casualty incidents have been identified in the US alone just during the last 11 months as of December of 22 when this recording is taking place. So we've seen this on a more rapid scale and then also the types of injuries and how fast they occur.
12:51
There are four main types of tourniquet devices. There are some that are linomatic. You see more more of these that were probably used in military settings. There's also hemostatic dressing such as you're looking at CLOCS gauze. And then you have a junctional hemorrhage control They and then also airway management.
17:08
A person may have 7, you know, up to 1500 liters approximately, and they still may have a relatively normal blood pressure at that point in time. So this is being they're compensating to a certain point. And if you continue to lose blood product, out of the circulatory system, then the body starts to compensate, you move into shock, you get you then get into hypoparfusion.
20:59
Tourniquets were recommended as the go to equipment for military personnel starting around 2004, 2005. 57% of death were by were prevented by early tourniquet use. Early studies that came out with no significant outcomes.
25:05
Sugarmint is looking at guidelines for field triage. They recognize they did recognize early positive military data. But again, they'd, you know, like to not include tourniquet use as a criteria.
29:11
The study was actual having a prehospital hemorrhage control protocol. This this should be in any in every pro emergency protocol, especially for wound and how this is treated. Ternicus have been military as a whole cell for a good 6 or 7 years. It's now moving into the trauma centers as well.
33:10
There is a disconnect or it's from the study pretty significant between what tourniquet. So it's really important to understand this from a training standpoint to train up to what the device is. Early application is key, especially before the onset of shock.
