Coagulation Cascade - Easy Way To Remember Intrinsic vs Extrinsic Pathways | PT or PTT?

The coagulation cascade is easily forgotten. I show you an easy way to remembering intrinsic vs extrinsic pathways, as well as whether PT or PTT
is the test needed. I also go through how different anticoagulants work on the coagulation cascade.

Vitamin K dependant factors: "1972 was the disco era" (1=10) 9,7,2 and diSCo=protein S&C) this has worked for me instantly after I had tried and failed to memorise them. I would always confuse them and would sometimes mix up the numbers after some time.

Ninja nerd taught me an easy way to remember: Intrisic pathway = 12 11 9 8, Extrinisic = 7 3, common pathway = 5 2 1 Put 10 in the middle. Intristic pathway you count down except 10 Extrinisic path way 7 + 3 = 10 Common pathway 5 * 2 * 1 = 10 Now you will never forget again

hello, I thought LMWH didn’t really have a reversal agent, which is why heparin is preferred in critical care situations

Is platelet factor 3 the same as tissue factor/factor 3?

[@sabaamjad632]

why i saw this so late ALSO please mention heparin monitoring is done by APTT n why?

[@sheliceallen68]

Can you give an example of injuries that would release contact activation or cause tissue factor to be released?

[@RhesusMedicine]

Hi Shelice! Generally speaking, we'd mainly be looking at trauma- which is of course a situation where coagulation would be a physiological attempt to reduce blood loss. There are of course others, but there are technical differences. Endothelial dysfunction, for example, may result from many causes including smoking, hypertension, diabetes mellitus, dyslipidemia etc. Endothelial dysfunction has been shown to contribute to the pathogenesis of thrombosis, but this is more of a pathological process rather than a physiological process seen in response to trauma! Hope that helps somewhat. Thanks for watching!

[@stacymethvin3426]

Thank you ! I needed this for my exam tomorrow and yes....I will be back as well, but the calcium Ion is Factor IV, not V. Just so you can make the change.

[@RhesusMedicine]

Hi Stacy! Thank you! (Also for the coffee!! 😁). I'm so glad it helped - as for the Factor V, you are absolutely correct that Factor IV is a calcium ion, in the video I say that Factor V is needed alongside a Calcium Ion, I can see however how it could cause confusion as they're listed together- I should have made it clearer! Thank you again for your support, it really means a lot. All the best with your exam :)
