Snakes can be distinguished by some physical features; consultation with a zoo or aquarium can help in identification of snake species. Also, fractures, abscesses, spider envenomations Spider and Scorpion Bites in Animals Spiders of medical importance in the US do not inflict particularly painful bites, so it is unusual for a spider bite to be suspected until clinical signs appear.

It is also unlikely the spider read more , or allergic reactions to insect bites or stings can all be confused with snakebites. Some bites do not result in envenomation or have been made by nonvenomous snakes. In Australia, venom detection test kits have been developed to detect the various snake venoms and determine the appropriate antivenom to use; however, these appear to be infrequently used for veterinary patients.

Snakebite with envenomation is a true emergency. Rapid examination and appropriate treatment are paramount. Owners should not spend time on first aid other than to keep the animal quiet and limit its activity. The following commonly touted measures are ineffective and can be potentially harmful: use of ice, cold packs, or sprays; incision and suction; tourniquets; electric shock; hot packs; and delay in presentation for medical treatment waiting until problems develop.

Intensive treatment should begin as soon as possible because irreversible effects of venom begin immediately after envenomation. Bite sites should be shaved and wounds cleansed thoroughly with germicidal soap.

For animals bitten by crotalids, the leading edge of tissue swelling should be marked on the skin with a skin marker at frequent intervals to monitor the spread of tissue injury. All snakebite patients should be monitored closely for a minimum of 24 crotalid to 48 elapid hours for the development of clinical signs.

Treatment for crotalid envenomation should be directed toward preventing or controlling shock, neutralizing venom, preventing or controlling coagulopathy, minimizing necrosis, and preventing secondary infection. Any dog or cat evaluated for treatment within 24 hours after a snakebite showing signs of crotalid envenomation requires intensive treatment, starting with IV administration of crystalloid fluids to combat hypotension.

Rapid-acting corticosteroids may be of benefit in the first 24 hours to help control shock, protect against tissue damage, and minimize the likelihood of allergic reactions to antivenom also known as antivenin ; however, prolonged use of corticosteroids is not recommended.

Monitoring for the development of echinocytosis or coagulopathy is recommended because these are often early signs of severe envenomation. Antivenom is the only direct and specific means of neutralizing snake venom. Antivenoms available against North American pit vipers include equine-derived polyvalent antivenom, ovine-origin polyvalent F ab fragment antivenom, and equine-origin polyvalent F ab 2 fragment antivenom.

The F ab antivenoms use the F ab components of the immunoglobulin molecule, resulting in an antivenom that has lower risk of allergic reaction, faster reconstitution, and potency similar to that of the polyvalent immunoglobulin. In the unlikely event of an anaphylactic reaction to the antivenom in a dog or cat, antivenom administration should be discontinued and epinephrine 0.

In severe envenomations, multiple vials of antivenom may be required, although this is frequently cost-prohibitive in veterinary patients. Antivenom generally helps considerably in managing the pain of a crotalid bite. Opioid analgesics may be used as needed for residual pain; NSAIDs are not recommended.

Hemoglobin glutamer bovine or hetastarch may be helpful to manage hypovolemia; however, colloids should be used with caution because of their potential to leak out of damaged vessels and pull fluids into tissue beds.

Several potential pathogens, including Pseudomonas aeruginosa , Clostridium spp, Corynebacterium spp, and staphylococci have been isolated from the mouth of rattlesnakes.

However, the incidence of wound infection after snakebites is low, and many veterinarians use antimicrobials only when notable tissue necrosis is present. Broad-spectrum antimicrobials such as amoxicillin potentiated with clavulanate or cephalosporins are preferred.

Tetanus Tetanus in Animals Tetanus is caused by the neurotoxin produced by Clostridium tetani , which is found in soil and intestinal tracts and usually introduced into tissues through deep puncture wounds.

read more antitoxin also should be considered, especially in horses, and other supportive treatment should be administered as needed eg, blood or plasma transfusions in the case of hemolytic or anticoagulant venoms. In most cases, surgical excision of tissue is impractical or unwarranted.

Antihistamines have been reported to be contraindicated; however, diphenhydramine hydrochloride 10—50 mg, SC or IV, once has been shown to be helpful to manage fractious patients and may possibly assist in minimizing risk of allergic reactions to antivenom.

Animals bitten by elapids may be treated with supportive care as needed IV fluid therapy, ventilatory support, anticonvulsants, etc and antivenom, if available. Antivenom against coral snake venoms is no longer manufactured in the US, although some practitioners have received special permission to import coral snake antivenom from Mexico.

Michael Tednes ; Todd L. Authors Michael Tednes 1 ; Todd L. Slesinger 2. Snakebites are responsible for a significant degree of morbidity and mortality worldwide, especially in low resource countries.

There are over species of identified venomous snakes worldwide, with the majority belonging to the Viperidae and Elapidae families. Common names among the Viperidae family are vipers, pit vipers, and adders.

Distinguishing features of the Viperidae family include long, retractable fangs, triangular heads, elliptical pupils, and small scales on their tails.

The pit vipers also have a heat-sensing pad adjacent to their nares for infrared vision. Common names among the Elapidae family are cobras, coral snakes, mambas, and copperheads. The Elapids can be distinguished from the Viperids as they have fixed, short fangs, less triangular heads, circular pupils, and larger scales on their tails.

The remainder of the venomous snake species belongs to the Atractaspididae, Colubridae, and Hydrophidae families. This activity discusses the evaluation and management of snake envenomation and the associated toxidromes.

It highlights the importance of effective first aid, patient monitoring, and targeted treatment throughout the disease process by the interprofessional team. Objectives: Identify the most common symptoms associated with snake envenomation worldwide. Describe the presentation of a patient exhibiting systemic venom toxicity.

Outline the management considerations for patients with systemic venom toxicity. Summarize the importance of improving care coordination among the interprofessional team to enhance the delivery of timely and effective care to patients suffering from a snake envenomation.

The pit vipers also have a heat-sensing pit adjacent to their nares for movement detection to aid in hunting prey. Common names among the Elapid family are cobras, coral snakes, mambas, and copperheads. Snake envenomation worldwide is primarily related to occupational exposure, such as in farmers and hunters, but is also seen among tourists exploring the outdoors.

When snake envenomation occurs in humans, the initial damage is local around the site of the bite and may spread to systemic toxicity depending on the species. Snakes primarily use their venom production for targeting prey, but it is also a form of self-defense.

When venom gets released with their bite, the overall toxicity is dependent on both the volume of the venom released and the median lethal dose LD50 of the venom. There are an estimated 1. The first being a higher prevalence of venomous snakes in a more densely populated region with poorer living conditions.

The second factor is that the access to healthcare in these regions is limited with long travel times to reach a suitable treatment center and lack of antivenom availability. Within the United States, the vast majority of snake envenomations occur in the southwest states with envenomations from the Viperidae family.

The symptoms seen from snake envenomations are mainly due to the toxic components in their venom. The exact composition ranges from species to species and can vary significantly from localized tissue destruction to profound coagulopathies.

The clinical effect on humans is related to both the potency and the volume of the toxin released during the snake bite. The venom released by the inland Taipan from Australia is the most potent in the world with a lethal dose of only 0. The composition of snake venom from a single species of venomous snake can consist of up to different toxic elements.

Local tissue destruction is primarily due to hyaluronidase and proteolytic enzymes in the snake venom, which can lead to local tissue edema, blistering, and tissue necrosis. Phospholipase A2 is a common component of snake venom and causes local tissue damage.

This compound has both local effects of the surrounding tissues as well as systemic effects on the vascular system and nerve endings. There are a variety of other proteins and polypeptides with toxic effects, such as neurotoxins and hemotoxins.

Most of the neurotoxic effects are secondary to damage at both the presynaptic and postsynaptic terminals of the neuromuscular junction. Presynaptic neurotoxins, such as phospholipase A2, damages the terminal axon, which prevents the release of acetylcholine, causing diffuse paralysis.

In contrast, the postsynaptic neurotoxins, such as alpha neurotoxin, responds well to antivenom and anticholinesterase administration as the toxin binds directly to the acetylcholine receptor. There are a wide variety of hemotoxins with effects on the coagulation cascade, platelet activation, and fibrin clot formation.

Most of the toxins lead to an increased bleeding tendency secondary to a consumptive coagulopathy and defibrination. There are, however, some hemotoxins that promote clotting and thrombosis.

A detailed history of a patient suspected of having a snakebite is essential to delineate treatment options moving forward.

Information to obtain includes the timing and location of the bite, the onset of any symptoms the patient has been experiencing, and any first aid administered in the field. Gathering a past medical history with detail to which medications they are on, specifically anti-platelet and anti-coagulant medications, and any allergies that would prohibit them from receiving an antivenom, such as horses.

If possible, information on the offending snake should be gathered. This information should be compared to the local database of venomous snakes located on the WHO website to see if a local antivenom exists.

Factors that contribute to the severity of the bite include size of the victim, with larger patients doing better, part of the body bitten, exertion following the bite, depth of the bite, species of snake causing the bite, time to the presentation at the hospital, and initial first aid given at the scene [5].

The physical exam may or may not reveal fang marks at the injury site. There could be local tissue damage, such as ecchymosis, blistering, or even tissue necrosis. Neurotoxic effects will initially present with generalized weakness, ptosis, and ophthalmoplegia; this may progress to paralysis of the facial muscles, and eventually, respiratory failure secondary to obstruction or paralysis of the diaphragm.

Significant bleeding from the puncture site, epistaxis, or evidence of spontaneous bleeding could indicate a hemotoxic effect. Patients may present with signs of shock secondary to venom-induced vasodilation, hypovolemia, or even anaphylaxis in some patients [6].

The physical exam could help indicate the species of snake inflicting the bite. In general, Elapid bites are associated with minimal local tissue damage and have a neurotoxic syndrome with systemic toxicity.

Viperid bites are associated with profound local tissue damage and have a hemotoxic syndrome with systemic toxicity. Symptoms that may suggest systemic effects of the envenomation include nausea, vomiting, abdominal pain, lethargy, muscle weakness, muscle fasciculation, and severe headache.

It is important to recognize these symptoms early to prompt initiation of antivenom administration. Ancillary study testing should target the suspected toxin envenomation.

In the case of unknown exposure and signs of systemic toxicity, a broad initial workup should take place.

Laboratory testing would include a complete blood count, prothrombin time, partial thromboplastin time, fibrinogen in the case of suspected hemotoxin and a creatinine kinase, basic electrolytes, and urinalysis for possible developing hematuria or proteinuria.

For cases of neurotoxicity, the patient requires end-tidal CO2 monitoring, or serial arterial blood gases to evaluate for developing respiratory acidosis. They should also undergo frequent neurologic checks to monitor the progression of the toxicity.

There has been the development of rapid venom testing within some centers mostly Australia , but the data shows that these are only useful to confirm the suspected species of envenomation and that a negative result cannot exclude a particular species.

Additionally, the wound site should be monitored carefully for the spread of edema, development of blisters, or signs of compartment syndrome. If compartment syndrome becomes a concern clinically, the definitive diagnosis is possible by obtaining a direct compartment pressure.

If this is greater than 30 mmHg of pressure, it is consistent with the early development of compartment syndrome. The initial first aid at the scene should be minimal and aim at getting the patient to the nearest treatment center quickly.

Varying opinions exist regarding the usefulness of placing the affected extremity in a splint and keeping it at heart level. Therefore, this should only occur if it will not delay transportation. Removal of jewelry and any constrictive clothing on the affected limb is necessary due to the possibility of swelling and circulatory compromise.

The patient should be kept calm and encouraged not to exert themselves as this could increase the snake venom absorption. Pressure bandages are another controversial topic. If the identity of the snake species is known to cause neurotoxicity and no local tissue damage, the application of a pressure bandage could slow the spread of the venom.

However, if the venom is known to cause local tissue damage, the implementation of the pressure bandage may worsen the damage inflicted to the extremity. Application of a tourniquet proximal to the bite results in higher morbidity without any improvement in outcomes, so this practice has been discouraged.

The use of venom extractors has also demonstrated to be ineffective. Local wound manipulation, such as incision or washout, is generally not suggested. Measurement of the progression of swelling form Crotalidae envenomation is essential to decide if antivenom is indicated.

Place ink mark on the proximal edge of the bite swelling as a baseline for serial measurements. Mark the progression of swelling with a skin marker, noting the time. Measure the circumference of affected extremity at the same level each time i.
