Hy everyone,
I am 2 weeks away from purchasing a pair of 2 ft. long puff adders(Bitis arietans) and a subadult Trimeresurus albolabris. As some of you might know, I also have an almost adult Western Diamondback Rattlesnake(Crotalus atrox).
The person that is selling me the puff adders suggested I buy a venom extracting pump for any life threatening eventuality. The thing is that there is no exotic antivenom in Romania as this country only has about a dousin exotic hot keepers. In the case of a venomous invenomation from any of my exotics I would have to travel to Hungary for antivenom and was wondering if extraction pomps actualy work, if they could actualy offer me some extra time.
Are there any studies that prove the concrete results of these gadgets ?
Anticipated thanks,
Best regards, Alex S.

Best way to put it is that the sucking devices ... well... suck. They are useless. Dr. Sean Bush did some very nice studies showing this.

If you are buying puff adders, you should seriously consider buying in some SAIMR Polyvaent antivenom from South Africa - it's fairly affordable and a pretty good antivenom. Go to http://www.savp.co.za/
Perhaps some of the other exotic venomous keepers in Romania couldclub together to put together a national antivenom bank?
Cheers,
WW

I'd like to see a study performed on suction devices used solely on short fanged elapid bites, where the quantity of venom is measured from the serosanguinous fluid removed. (BGF? Sounds like something for you to undertake.)
Definitive answers that haven't been quantified are a bit troublesome. I know what SB's study entailed (porcine models/crotalid venom), but are there variables that haven't been looked at? -- species, size of specimen, venom viscosity, depth of penetration, location of bite, type of tissues involved -subq,IM, etc.

Another problem with Bush`s study is that they did not start using the Extractor until 3 minutes after they injected the venom. Even then it did still remove up to 2% of the injected venom.
Three minutes would allow some of the venom to move away from the wound where it might not be removed by negative pressure.
I keep an Extractor in my snake room and in my car, where they could be brought into use within a few seconds following a bite.
It is possible that if they were rapidly used, they would remove more venom than after a three minute waiting period.
It would also seem that if they were used along with other first aid measures while transporting the victim to the hospital, they are not going to hurt, and just might help.
I agree with Chris in more detailed studies are needed on these devices.
Best Regards JohnZ

Hy everyone,
Thanks for the help.
WW, I`ll contact the South African Antivenom people to get some info on the prices. A national antivenom bank would be a very good ideea.
Best regards, Alex S.

Chris
the Liverpool School of Tropical Medicine (Theakston/Ried) reviewed extractor kits many years ago and came to the same conclusion as SB. Unfortunately I can't find the paper, so I don't now what test animals and snakes were used in the study. It's possible that WW may have a copy.
I believe 3 min's is a realistic time, for some one to come to reality and react appropriately to being bitten. Those of us who work/hobby is with venomous snakes have a bite plan in our heads as well as documented. Joe Bloggs the active out doors person ie hiker, camper, hunter etc does not. And will react differently and it may take some time before they realise about their venom extractor in the first aid kit.
