Chapter 3: How to Recognize a Potentially Serious Snakebite
A snakebite can look deceptively minor.
Two small punctures may be visible, or there may be several superficial scratches. Sometimes there is considerable swelling, while other times the external wound initially appears relatively unremarkable.
That's why the appearance of the skin isn't enough to determine the severity.
Possible local symptoms include:
- Increasing pain
- Swelling
- Redness
- Bruising
- Blistering
- Bleeding
- Tissue discoloration
- Progressive swelling around the bite
But venom doesn't always remain a local problem.
Certain snake venoms contain neurotoxins that can interfere with nerve and muscle function.
A person may develop drooping eyelids, blurred or double vision, difficulty speaking, trouble swallowing, weakness, or eventually breathing difficulties.
Other venoms can interfere with blood clotting.
In those cases, a person may develop unusual bleeding, bruising, blood in urine, bleeding from the gums, or other signs of a coagulation problem.
Some venoms cause significant local tissue injury.
Pain and swelling may increase dramatically, with blistering or tissue damage developing over time.
This is one reason why waiting at home to see what happens can be dangerous when a venomous bite is possible.
Children, older adults, and people with certain medical conditions may also have particular vulnerabilities.
Another misconception is that the absence of obvious fang marks proves the snake was harmless.
It doesn't.
A snake may bite at an unusual angle, one fang may penetrate more effectively than the other, or the wound may become difficult to distinguish from ordinary punctures.
The reverse is also true.
A dramatic-looking bite does not automatically prove that venom was injected.
The medical team may need to monitor the patient for several hours depending on the suspected species and circumstances.
They can assess vital signs, neurological function, swelling, blood clotting, and other indicators.
If appropriate, antivenom may be administered.
Antivenom is produced specifically to counteract the effects of particular snake venoms and is generally given when clinicians determine that the benefits outweigh the risks.
This is why identifying the snake from a safe distance can be helpful—but trying to identify it personally is never worth another bite.
