First Aid for SEA URCHIN PUNCTURES

For simple punctures, gently pull out any protruding spines.
 

These are so brittle they almost always break off in the wound. Neither urine nor vinegar dissolves such embedded spines. Never try to crush them by hitting the area with a heavy object. This only adds to the injury. In most cases, the body either absorbs spine fragments in 24 hours to 3 weeks, or they work themselves out through the skin. Most wounds heal in about one month.
 

Applying heat for pain control is unproven. Some authors recommend it. Others believe it is of no benefit and should not be done.
 

The thick spines of the `ina do not dissolve as wana spines do.
 

If `ina spines are embedded in the flesh (a rare occurrence), or any sea urchin spines have penetrated a joint or nerve, see a doctor. Also see a doctor if a sea urchin wound shows any sign of infection, such as redness, warmth, or pus formation.
 

Victims with generalized weakness, shortness of breath, and/or nausea and vomiting after a puncture should go directly to an emergency facility.
