    You can remember what drug is for which pathway by thinking of the alphabet. H for heparin is followed by I for intrinsic, W for warfarin is followed by X for eXtrinsic. (Heparin=Intrinsic; Warfarin=eXtrinsic). I just came up with this after watching your video, thanks so much!

    My silly way to remember the relationships:
    PTT - play table tennis (you play table tennis inside = intrinsic). Its heparIN
    PT - play tennis (you play tennis outside = extrinsic) By deduction warfarin is here.

      Remember War is Extrinsic .... we don't go to war intrinsically...

      But warfarIN could work with INtrinsic too... so not ideal to solely rely on this mnemonic

    Missing factors
    Factor 1 = Fibrinogen
    Factor 3 = thromboplastin
    Factor 4 = Calcium
    Factor 13 = Fibrin stabilizing factor

  • @mscrawford87

    I always remember that PTT is affected by Heparin, because PTT has two "ts" next to each other (like tt, or TT) which resemble the capital letter "H" although it depends on your font/handwriting. This might just work for my brain only, but hopefully it helps others! :)

    Write a capital I ( the one with bars on the either end of the line) and turn it 90 degrees; it becomes H.
    I for intrinsic; and H for Heparin.

    I remember heparin=PTT and warfarin-PT by remembering to make 10 letters for both so... it goes like this
    H E P A R I N ( P T T ) = 10 letters
    W A R F A R I N ( P T ) = 10 letters

  • @marissacopasweaver2213
    @marissacopasweaver2213 6 років тому +26

    I really like this mnemonic, but my OCD struggles with the final picture because the last step of the common pathway is Fibrinogen (I) to Fibrin (Ia). So I add "1" to the bottom of the common pathway and said that it stands for "One common math problem (pathway)".

  • @toherstudies
    @toherstudies 4 місяці тому +2

    My professor had this mnemonic which actually helped bc I love Brad Pitt haha
    (brad) PiTT -- intrinsic pathway, PTT
    (I love) PeTs -- extrinsic pathway, PT
    Hope that helps!

    a great way to remember is we measure INR aka PT for warfarin -> warfarin blocks formation of VitK dep factors --> 2 7 9 and 10 --> 7 has the shortest half life and degrades first = easy way to check warfarin levels bc its the first factor to go

  • @dr.poornaprajna
    @dr.poornaprajna Рік тому +2

    PT (physical education teacher) is always OUTside. He is FAST and always ready for the WAR!
    PT → OUT (extrinsic pathway) → FAST (fast reaction) → WAR (warfarin)

    I've a question. As warfarin blocks vit K dependent factors like 2,7,9 and 10, As factor 9 is part of the intrinsic pathway so why does PTT not affected by warfarin?

    I hv to tell you that this video confuses most of clinicians who memorized the cascade the way it is.
    1st: memorize the cascade as it is with Roman numerals
    2nd: remember that 2+7->9->10 that’s Warfarin which is given externally (PO) and thus affect the extrinsic pathway more (PT)
    3rd: Heparin is given IV, that’s intrinsic and affects F XII -> F XI -> F IX
    4th: heparin works faster (IV), but warfarin works way slower (PO)
    Pls remember that in clinical practice we rarely use either and now we use other oral inhibitors (NOACS) and SQ inhibitors (LMWH etc), which were not discussed here at all.
    In summary this video is way confusing and way way way out of date. Pls replace it.
