Neurologic
- Excitement
Two children are the latest victims of attacks by these dangerous ophidians, which are particularly excitable at the height of Costa Rica’s torrential rainy season. [news.co.cr]
Even horses that experience difficulty breathing can usually breathe well enough to survive, unless they become excited or are exercised. The swelling peaks in a day or two and then begins to gradually decrease over time. [horsesidevetguide.com]
However with these exciting resources comes some pretty serious risks including Tick Fever and Leptospirosis. Another danger, although not as common, is snake bite. [animalemergency.com.hk]
“Now don’t get too excited, but I’ve just caught a Kaulbacki,” he says, looking pleased but exhausted from a long hike and a six-metre climb up a tree. [theconversation.com]
- Rabies
Snakes do not carry or transmit rabies. Not all bites by venomous snakes result in venom poisoning. In more than 20% of bites by rattlesnakes and moccasins, for example, no venom is injected. [webmd.com]
Snakes do not carry or transmit rabies. A victim who is very young, old, or has other diseases may not tolerate the same amount of venom as well as a healthy adult. [emedicinehealth.com]

Occasionally, vesicles or hemorrhagic bullae may be present. 1 Systemic symptoms from a pit viper bite include a metallic taste in the mouth, paresthesias, weakness, tachycardia, numbness, lethargy, altered mental status, muscle twitching, nausea, vomiting [elitecme.com]
Further, alcohol or drugs that could alter the victim’s mental status are not advised. A helpful technique is to mark with permanent marker the initial area of erythema, edema, and ecchymoses as well as subsequent progression. [clinicaladvisor.com]
Progressive local injury (swelling, ecchymosis), a clinically evident coagulation abnormality, or systemic effects (hypotension, altered mental status) are strong indications for antivenin treatment. [aafp.org]
- Irritability
Amphibians’ skin secretions fall under the poisonous category, but calling them irritants is a better way to describe many, because most skin secretions are not life threatening especially where India is concerned. [jlrexplore.com]
It has an irritable disposition. It will strike with little provocation. Its venom is hemotoxic, causing severe tissue damage. Deaths have occurred from the bites of these snakes. The Eyelash pit viper is largely nocturnal. [wildernessarena.com]
“Though slow-moving, it has an irritable disposition when disturbed and strikes fast.” [scidev.net]
Their "pits" are heat sensors located between the eyes and nostrils and are used to locate small warm blooded animals for food and on occasion any part of a large warm blooded animal that irritates or threatens them, accidentally or on purpose. [ems1.com]

PROGNOSIS AND RELEVANT FACTORS The prognosis for most pit viper bites is usually fair to good. [horsesidevetguide.com]
Snakebite Prognosis and Outcomes Although the vast majority of victims bitten by venomous snakes in the United States do very well, predicting the prognosis in any individual case can be difficult. [emedicinehealth.com]
The sooner treatment is initiated the better the prognosis. [palenciapetclinic.com]
Etiology
Etiology In the United States, more than 40% of victims put themselves in danger by either handling pets or attempting to capture reptiles in the wild. [emedicine.medscape.com]
(Etiology) Malayan Pit Viper Snake Bite takes place when one comes into contact with the venomous and dangerous Malayan pit viper, usually unintentionally or inadvertently. [dovemed.com]

"In the past five or 10 years, there's been a backing off in first aid from really invasive things like making incisions," says Arizona physician David Hardy, M.D., who studies snakebite epidemiology. [consejo.bz]
Epidemiology Frequency United States Snakebites frequently go unreported. Approximately 8,000 bites are reported in the United States annually, with approximately 2,000 delivered by venomous snakes. [emedicine.medscape.com]
Pathophysiology
Once the venom has initiated the pathophysiological events, the team will need to identify the action and therapeutic effects of rutin. [drugtargetreview.com]
Pathophysiology Crotalid venom is produced and stored in paired glands below the eye. It is discharged from hollow fangs located in the upper jaw. Fangs can grow to 20 mm in large rattlesnakes. [emedicine.medscape.com]
Pathogenesis Pathophysiology Rattlesnakes have a pair of long, hollow fangs that lie in the rostral portion of the head, folded back against the roof of the mouth. These are connected to venom glands by small tubules or ducts. [vetstream.com]
Other systemic manifestations depend upon the pathophysiological changes induced by the venom of that particular species (See Fig. 1). [priory.com]
It is likely that common pathophysiological mechanisms are responsible for both these important systemic complications of hump-nosed viper bite. Hump-nosed viper venom contains procoagulant, nephrotoxic, myotoxic and cytotoxic properties. [omicsonline.org]
Prevention
Snakebite prevention should be taught to patients. [aafp.org]
Preventing Snakebites The snake is almost always more scared of the human, than the human is of the snake, it is assumed because giving the snake the opportunity to escape prevents most bites. [emedicinehealth.com]
