Background [1]

Common stingray (Dasyatis pastinaca)
A stingray's stinger (ruler in cm)
  • Stinger contains a retroserrate barb and venom glands located on the tail.
  • There are two phases to injury.
    • Phase one is d/t the traumatic injury from the barb, which can inflict injury to vital organs (e.g. Steve Irwin)
    • Phase two is d/t heat-labile venom release, which causes vasospasm with possible limb ischemia, cardiotoxicity, seizure, and/or death.
  • Generally causes local symptoms without systemic effects
  • Often occurs when swimmers accidentally step on stingray in shallow water. Can be avoided by shuffling feet along bottom.

Clinical Features

Differential Diagnosis
