JELLYFISH OR PORTUGUESE MAN-OF-WAR REACTIONS
Description:
The jellyfish and Portuguese man-of-war have long, stinging
tentacles. They produce lines of redness and burning pain.
Sometimes they cause generalized symptoms, such as weakness,
chills, fever, or vomiting.
First Aid:
- Wipe off any stinging tentacles with a thick towel. Be
careful to protect your hands, since the stingers can
penetrate gloves.
- Neutralize the venom with a continuous application of
alcohol (in any form) for 30 minutes.
- Apply 1% hydrocortisone cream (no prescription needed)
four times a day for a few days to reduce itching.
Call Your Child's Physician Immediately If:
- Any generalized symptoms, such as weakness, chills,
fever, or vomiting, have developed.
VENOMOUS FISH REACTIONS
Description:
Venomous fish--such as the stingray, stonefish, and scorpion
fish--always cause pain and redness in the area that was
stung. They also often cause weakness, sweating, fever,
vomiting, muscle cramps, or even shock. The stingray has
one or more venomous spines on its tail. The stinging fish
usually have venom in dorsal spines.
First Aid:
Fortunately, the venom of all these fish can be destroyed by
heat.
- Remove any particles of stingray spine left in the wound
and rinse the area with sea water.
- Apply a meat tenderizer solution for 15 minutes.
- Immerse the stung part of the body in water as hot as can
be tolerated (but under 120 degrees F, or 49 degrees C).
Keep it in the hot water until the pain is completely
gone (30 to 90 minutes).
Call Your Child's Physician Immediately If:
- Any generalized symptoms have developed.
- The skin is split open after a stingray sting and may
need stitches.
- The barb needs to be removed after a stingray sting.
CUTS OR LACERATIONS FROM FISH
Description:
Some fish--for example, moray eels, sharks,
barracudas--cause a bite mark without injecting any venom.
First Aid:
Wash the area with sea water. Later, wash with soap and
water.
Call Your Child's Physician Immediately If:
- Bleeding won't stop after 10 minutes of direct pressure.
- The skin is split open and may need stitches.
- A puncture wound is present.
STINGS (SUCH AS SEA URCHINS, SEA ANEMONES, CORAL)
Description:
Sea anemones (sea nettle) or coral can cause swelling and
pain in the area that was touched for 24 to 48 hours. A sea
urchin can cause pain if part of a venomous spine breaks off
in the skin. If not removed, it may dissolve or cause a
persistent tender lump (a foreign-body reaction).
First Aid:
Neutralize the venom with a strong solution of meat
tenderizer for 15 minutes. If meat tenderizer is not
available, use ammonia. Then wash the area carefully with
soap and water. If a large fragment of a sea urchin barb is
in the skin, try to remove it with a sterile needle and
tweezers as you would do for a sliver.
SHOCKS (SUCH AS ELECTRIC EELS)
Description:
Your child may feel shocked, stunned, or partially paralyzed
after contact with an electric eel.
First Aid:
Your child needs no treatment other than lying down with the
feet elevated until he or she feels better. Your child will
feel and act normal in 20 to 30 minutes.
