Educational Pearls:

 

  • Snake bites commonly occur between April and October.
  • Rattlesnake bites are the most common.
  • Venom contains proteins/enzymes that cause local inflammation, coagulopathy, and systemic effects (hypotension, angioedema, renal failure, etc.) along with neurotoxins may cause fasciculations, ptosis, drooling, or hyporeflexia.
  • Management:
  • Mark site for swelling.
  • Monitor progression.
  • Elevate and immobilize injured limb and treat pain.
  • Check basic labs including coagulation studies, and update tetanus.
  • Antidote is CroFab and use if patient has systemic symptoms.  Anaphylaxis is a known complication of CroFab
  • Avoid: ice, tourniquets, and incision and drainage.
