History:
- Type of bite/sting
- Bring description or photo with patient for identification
- Time, location, size of bite/sting
- Previous reaction to bite/sting
- Domestic vs. wild
- Tetanus and rabies risk
- Immunocompromised patient
Significant Findings:
- Rash/broken skin/wound
- Pain
- Soft tissue swelling
- Redness
- Blood oozing from the bite wound
- Evidence of infection
- Shortness of breath/wheezing
- Allergic reaction/hives/itching
Differential:
- Animal/human bite
- Snake/spider bite
-
Insect sting/bite
- Infection risk
Treatment:
- Consider Oxygen
- Position patient supine; immobilize area of limb
- Remove rings,bracelets, and other constricting items
- Consider obtaining BGL
- Consider 12- Lead EKG
Allergic/anaphylactic reaction ?
Spider bite/bee/wasp ?
-
- Apply ice to affected area
Muscle spasm ?
-
- Notify receiving facility or contact Medical Control
Snake, Animal or human bite ?
Significant Pain?
-
- Notify receiving facility or contact Medical Control
PEARLS:
- For pediatrics muscle spasms, call (Medical Control) prior to Midazolam (Versed) or Lorazepam (Ativan) administration.
- Human bites have higher infection rates than animal bites due to normal mouth bacteria.
- Carnivore bites are much more likely to become infected and all have risk of rabies exposure.
- Cat bites may progress to infection rapidly due to a specific bacteria (Pasteurella multicoda).
- An animal bit incident report must be made to SC DHEC i the patient is not transported by EMS and animal control is not on-scene.
-
Poisonous snakes in this area are generally of the pit viper family:
- rattlesnake
- copperhead
- water moccasin.
-
Coral snake bites are rare:
- Very little pain but very toxic. "Red on yellow - kill a fellow, red on black - venom lack."
-
Black widow spider (black spider with red hourglass on belly):
- Bites tend to be minimally painful, but over a few hours, muscular pain and severe abdominal pain may develop.
-
Brown recluse spider (brown spider with fiddle shape on back):
- Bites are minimally painful to painless. Little reaction is noted initially but tissue necrosis at the site of the bite develops over the next few days.
- Envenomation is generally worse with larger snakes and early in spring. If no pain or swelling, envenomation is unlikely (except for coral snakes).
- Evidence of infection:
-
- swelling
- redness
- drainage
- fever
- red streaks proximal to wound.
- Immunocompromised patients (i.e. diabetes, chemotherapy, transplant patients) are at an increased risk for infection.
