A venomous snake bite is a medical emergency. If you or someone with you has been bitten, call 911 or go to the nearest emergency room right away, and call Poison Help at 1-800-222-1222 on the way if you can. Keep the bitten hand or arm still in a comfortable, neutral position, take off rings, watches, and bracelets before swelling starts, and leave the wound alone. Do not apply a tourniquet, cut the wound, try to suck out venom, or use ice. The treatment that matters most in the first hours, antivenom, is given in the hospital. This page explains what comes after that emergency care, when the hand begins to heal and some patients need a hand surgeon.

Dr. John Anastasatos approaches snake bite injuries of the hand from formal hand surgery training. After his plastic surgery residency at the University of Alabama at Birmingham under Dr. Luis Vasconez, he completed a fellowship in hand, upper extremity, and microsurgery, and he later presented “Infections of the Hand” at UAB Grand Rounds. He went on to serve as Assistant Professor of Plastic Surgery at UAB and as an attending surgeon at UAB Hospitals, The Children’s Hospital, and the Veterans Administration Hospital. Board certified by the American Board of Plastic Surgery and a Fellow of the American College of Surgeons (FACS), he has more than two decades of experience as a plastic surgeon and has practiced in Beverly Hills since 2007. His role begins once emergency treatment is underway, evaluating how the skin, tendons, nerves, and joints of the hand are healing and treating what needs repair.

What Rattlesnake Venom Does to the Hand

The venomous snakes of Southern California are rattlesnakes, a type of pit viper. Rattlesnake venom is a mix of proteins that can damage tissue near the bite, cause swelling that spreads up the arm, and interfere with normal blood clotting. Some species, including the Mojave rattlesnake found in desert areas, can also affect the nerves and muscles. The hand is especially vulnerable because its tendons, nerves, blood vessels, and small joints sit close together under thin skin. A bite to a finger or the hand can lead to blistering, death of skin and tissue near the bite, and stiffness that lasts well after the venom itself has been treated.

Not every bite injects venom. Some are “dry bites,” but there is no way to tell at home, so every bite needs emergency evaluation. Coral snakes, whose venom mainly affects the nervous system, are not native to California and are rarely a concern in the Los Angeles area.

Snake Bite First Aid Myths That Can Make an Injury Worse

Much of the snake bite advice that has been passed down for generations is now known to cause harm. Current emergency guidance advises against all of the following:

• Tourniquets: Tying off the arm traps venom in the hand and fingers, concentrates the damage there, and can lead to tissue loss.
• Cutting the wound: Slicing the bite does not remove meaningful venom and adds a new injury that can damage tendons or nerves and become infected.
• Suction: Mouth suction and commercial suction kits remove little or no venom and can injure the skin around the bite.
• Ice or cold water: Cold can add a cold injury to tissue that is already damaged.
• Waiting to see what happens: Symptoms can start mildly and worsen over hours, and antivenom works best when it is started early.

Severe swelling after a hand bite can look alarming and is sometimes mistaken for compartment syndrome, a dangerous rise in pressure inside the muscles. True compartment syndrome after a snake bite is uncommon. Antivenom is the main treatment for swelling and tissue damage, and emergency surgery to release pressure is reserved for the rare patient whose measured pressures stay high despite it.

How Hand Surgery Helps After a Snake Bite

Most snake bites heal without surgery. When the bite has damaged the hand, care usually unfolds in stages, and each patient’s plan depends on the location of the bite, the amount of tissue injury, and how the hand responds to treatment.

• Hospital treatment: The emergency team gives antivenom when it is needed, monitors blood clotting and swelling, updates tetanus protection, and may ask a hand surgeon to evaluate a severely swollen or blistered hand.
• Wound care: If skin or deeper tissue dies, removing the dead tissue allows healthy tissue to heal and lowers the risk of infection. Antibiotics are used when there are signs of infection.
• Hand therapy: Early, guided movement, swelling control, and splinting help prevent the finger and wrist stiffness that is one of the most common lasting problems after a hand bite.
• Reconstruction: Once the wounds have healed and swelling has settled, Dr. Anastasatos can address what remains, which may include skin grafts or local flaps, release of tight scars that limit motion, tendon repair, nerve surgery, or scar revision and contour correction.

What to Expect During Recovery

Swelling after a hand bite can take several weeks to resolve, and stiffness may take longer to improve. Patients who keep up with hand therapy usually regain more motion than those who rest the hand completely. If reconstruction is needed, Dr. Anastasatos generally waits until the tissue has stabilized, often several months after the bite, so that surgery is planned around the hand’s final condition rather than its early swelling. Recovery from reconstruction depends on the procedure and ranges from a few weeks for scar revision to longer periods when tendons or nerves are repaired. Results vary from patient to patient, and some bites leave lasting changes in sensation or motion even with excellent care.

“The most important decisions after a snake bite are made in the emergency room, and the best thing a patient can do is get there quickly. My work usually comes afterward. I look at how the skin, tendons, and joints of the hand are healing, and I plan any surgery around getting the hand working again, not just closing the wound.” — Dr. John Anastasatos

Frequently Asked Questions About Snake Bites of the Hand

What should I do right after a snake bites my hand?

Call 911 or go to the nearest emergency room immediately. Keep the hand still in a comfortable position, remove rings and anything tight, and do not use a tourniquet, cut the wound, try suction, or apply ice.

Should I come to a plastic surgeon’s office instead of the emergency room?

No. A recent snake bite needs hospital care, where antivenom and monitoring are available. Dr. Anastasatos sees patients after emergency treatment for wound problems, stiffness, scarring, and reconstruction.

Is antivenom safe?

The antivenoms used in the United States are well tolerated by most patients. Allergic and delayed reactions can occur, which is why antivenom is given in the hospital with monitoring, and the emergency team weighs those risks against the effects of the venom.

Will I need surgery after a snake bite?

Most people do not. Surgery is considered when tissue has died, when scars or stiffness limit how the hand works, or when tendons or nerves have been injured. Learn more about hand surgery options.

Can a snake bite cause permanent damage to the hand?

It can. Some patients are left with stiffness, numbness, scarring, or changes in the shape of a finger. Prompt emergency care and early hand therapy lower that risk, and reconstruction can improve many lasting problems.

When can reconstruction be done?

Reconstruction is usually planned after the wounds have healed and swelling has settled, often several months after the bite. Scar treatment may be part of that plan, including care for hypertrophic scars.
