TREAT A BROWN RECLUSE SPIDER BITE
a. Keep Casualty Calm. Keep the casualty calm and quiet.
b. Cleanse Wound. Cleanse the wound (bite punctures) with an antiseptic
solution from your aid bag. If an antiseptic solution is not available, cleanse the area
with soap and water. Do not cut the puncture wounds.
c. Evacuate Casualty. Evacuate the casualty to a medical treatment facility.
Continue to monitor the casualty's vital signs. Be ready to treat the casualty for
anaphylactic shock should it develop. Administer oxygen, if needed.
NOTE:
Constricting bands are not applied because the venom does not dilute. It
goes deeper into the tissue and causes severe local tissue damage. If not
properly treated, gangrene (the death of tissue caused by a lack of blood
supply) can develop.
