Actually, krait bites also kill primarily through respiratory failure, but you are absolutely right about the latency period and the benefits of early a/v.
Giving a/v immediately is certainly recommended in at least some coral snake bite protocols I have seen. Once neurotoxic symptoms set in after coral snake bites, they are not easily reversed, particularly if presynaptic neurotoxins are involved (I believe they are in many coral snakes) - by the time symptoms appear, the damage is done. Respiratory failure is always a serious matter, even with mechanical ventilation in an ICU - there are a number of risk factors associated with that, including forms of pneumonia etc., quite apart from it being a fairly unpleasant experience. If early a/v injection can prevent systemic neurotoxicity from developing, then injecting it before symptoms develop may be a lesser risk than waiting. Also, i don't have the detailed costings for this sort of thing, but I suspect that a few days on a respirator in ICU, keeping a consultant busy, will cost you considerably more than the few vials of antivenom required for a coral snake bite - anyone have any more detailed info on that?
