What to do if you are bitten by a snake…

02.12.2010
…and how you can avoid snakebites in the first place

Should you be the victim of a snakebite, the best thing you can do is get to a hospital as quickly as possible, according to a new review article from the Journal of the American Academy of Orthopaedic Surgeons (JAAOS). Current medical treatments, including new medications and surgery, if necessary, are far more effective for snakebites than anything you can do on your own.

“Previous generations of antivenin medications were notorious for causing negative systemic reactions,” says Adam W. Anz, MD, an orthopaedic surgeon at Wake Forest University Baptist Medical Center, Winston-Salem, NC. “But the antivenins we have available today can not only help avoid long-term damage from the snake venom, but they can also prevent the need for more invasive medical treatment.”

Snakebite symptoms can range from pain, swelling, and bruising to an irregular heartbeat, paralysis, and muscle twitching.

Surgery is very rarely, yet sometimes necessary to treat damage incurred from a snakebite, in cases where severe swelling compromises blood flow. This is not the only reason that orthopaedic surgeons are often consulted on these types of injuries.

“Orthopaedic surgeons are experts in regard to treating the extremities, and the hands and feet are the parts of the body most often bitten by snakes,” says Dr. Anz. “This is why it is important for orthopaedic surgeons and the public to know about the effects of venom and the best ways to treat snakebites.”

Tips for avoiding snakebites:

Understand the types of environments where people are likely to encounter snakes. For example, wooded areas with deep piles of leaves or stacks of wood are frequently home to snakes.

If you encounter a snake, get away from it. Do not attempt to pick it up or threaten its safety in any way. More than half of all bites occur when people interact inappropriately with snakes.

If you are bitten:

Identify the type of snake if possible. If a smartphone or other camera is available, take a photo of the snake and bring it with you to the hospital.

Get away from the snake.

Do not attempt to suck out the venom.

Do not apply a tourniquet unless you have a great deal of knowledge about snakes and the effects of snakebites. For some types of venom, a tourniquet can actually do more harm than good.

Immobilize the affected body part.

Remove all rings or restrictive jewelry on the affected limb, since snakebites often cause swelling.

Get to a hospital or healthcare facility as quickly as you can. Do not wait and watch for symptoms.

Relevant facts and statistics:

Approximately 45,000 snakebite injuries are reported annually in the United States.

Seventy to 80 percent of snakebites occur in males.

More than half of snakebites are to the hand(s).

Most snakebites result from intentional exposure, whether in a professional context (e.g., snake handling) or nonprofessional context (e.g., playing with snakes in the wild).

Alcohol consumption is involved in the majority of bites, resulting from risky behavior.

The high correlation between alcohol use and hand injury implies that bites occur when the victim is behaving in an unsafe manner, not when he or she is attempting to evade the snake.

Im Focus: A “cosmic snake” reveals the structure of remote galaxies

The formation of stars in distant galaxies is still largely unexplored. For the first time, astron-omers at the University of Geneva have now been able to closely observe a star system six billion light-years away. In doing so, they are confirming earlier simulations made by the University of Zurich. One special effect is made possible by the multiple reflections of images that run through the cosmos like a snake.

Today, astronomers have a pretty accurate idea of how stars were formed in the recent cosmic past. But do these laws also apply to older galaxies? For around a...

Im Focus: Visual intelligence is not the same as IQ

Just because someone is smart and well-motivated doesn't mean he or she can learn the visual skills needed to excel at tasks like matching fingerprints, interpreting medical X-rays, keeping track of aircraft on radar displays or forensic face matching.

That is the implication of a new study which shows for the first time that there is a broad range of differences in people's visual ability and that these...

Im Focus: Novel Nano-CT device creates high-resolution 3D-X-rays of tiny velvet worm legs

Computer Tomography (CT) is a standard procedure in hospitals, but so far, the technology has not been suitable for imaging extremely small objects. In PNAS, a team from the Technical University of Munich (TUM) describes a Nano-CT device that creates three-dimensional x-ray images at resolutions up to 100 nanometers. The first test application: Together with colleagues from the University of Kassel and Helmholtz-Zentrum Geesthacht the researchers analyzed the locomotory system of a velvet worm.

During a CT analysis, the object under investigation is x-rayed and a detector measures the respective amount of radiation absorbed from various angles....

Im Focus: Researchers Develop Data Bus for Quantum Computer

The quantum world is fragile; error correction codes are needed to protect the information stored in a quantum object from the deteriorating effects of noise. Quantum physicists in Innsbruck have developed a protocol to pass quantum information between differently encoded building blocks of a future quantum computer, such as processors and memories. Scientists may use this protocol in the future to build a data bus for quantum computers. The researchers have published their work in the journal Nature Communications.

Future quantum computers will be able to solve problems where conventional computers fail today. We are still far away from any large-scale implementation,...
