diving and aspirin?

70-90% of divers "bubble", esp with multidive, multiday profiles. The vast majority of the bubbles are microscopic or "silent", meaning no discernable physiological effects. Standard thinking was that the effects of nitrogen in DCS is due to the physical obstruction/ pressure on tissue caused by a bubble of sufficient size. If we "come up slowly enough" our body can handle the offgassing nitrogen load, eliminating the nitrogen with normal breathing.
Well, nitrogen has other effects. It is considered a foreign substance in the blood stream, and the body recognizes that. Platelets are clotting substances in the blood, that initially respond to an abnormal surface (like a cut in the wall of a blood vessel, or cholesterol plaque buildup) by becoming activated, sticky, and forming a platelet plug. This is good if they are plugging a hole in a vessel, bad if they are plugging a coronary artery. That is why people with heart disease take an aspirin a day, to reduce the platelets activity and reduce the risk of platelet plugs in heart vessels that have plaque on their walls.
NItrogen bubbles being seen as a foreign substance activate platelets. This can cause "downstream" obstruction to blood flow to an extent much greater than the size of the bubble, since not there is now a plug also. Additionally, activated platelets and white blood cells release mediators, incl histamine and various other "evil humors" that cause swelling, leaking of fluid, inflammatory responses, etc. THis also causes local tissue edema, reducing blood flow and tissue perfusion.
All of this means that by slightly reducing the effect of platelets (just like folks with heart disease), we reduce the CHANCE and maybe extent of platelet activation in response to nitrogen bubbles, and thereby reduce the chance of DCS.
Other drugs that affect platelet function, like motrin, advil, aleve, etc will have similar effects. I don't think that "masking" DCS with an aspirin is really a clinical issue.

Do any of these destroy vitamin C?

Walter if you take in sufficient vit C in your diet via food and/or bioavailable whole food supplements then you don't have to worry about the negative offset of the aspirin.Other drugs that affect platelet function, like motrin, advil, aleve, etc will have similar effects.

My question is why take asprin to reduce the chances of DCS if one of the others work as well if they don't destroy vitamin C?

After talking to other divers and researching it a bit on my own, I would think it's a practice worth thinking about, especially on those week long dive vacations where you're diving a lot, or if pursuing deeper, more agressive, dives.

Yeah I know: I've been branded a non-group person - doesn't play well with others. I am so upset. Let me know if you want to have some fun, without the drama - I'm good for that.

Walter, I will look up the various meds listed and see if there is a difference on VItamin C effect. I must admit that I don't know.

I did not find info on the NSAID's (advil, aleve, motrin) having an affect on Vit C, but then, in my opinion, they are not as effective on platelets as aspirin, dose for dose. I will still be taking 325 mg of aspirin a day, and getting my Vitamin C from fruits, tomato juice, etc (screwdrivers and bloody mary's count)

So...if someone takes viagara before diving....does it effect their bouyancy??? What are the chances of getting 'it' 'bent'??? Will the nitogen bubbles react differently to 'that body part'??? Enquiring minds want to know.........!!!! heheNo but she's been listening to those of use who do!!! LOL!!!
