About 5-10% of such events are associated with life threatening consequences.2998108110112 The incidence of fatal reactions is unclear because of confusion with symptoms of envenoming, but some have been reported.112, Treat anaphylaxis at the earliest sign.2425 Suspend antivenom administration and inject adrenaline intramuscularly, ideally into the upper lateral thigh.2425 Additional treatment includes intravenous antihistamines and glucocorticoids and inhaled bronchodilators for bronchospasm.2425 Anaphylaxis can recur, and glucocorticoids do not prevent recurrence.112 On resolution of the episode, cautiously resume antivenom in patients with a definite indication for continued treatment.2425 Treat pyrogenic reactions with physical cooling, antipyretics, and intravenous fluids.2425, Late reactions may manifest a week after administration.108111113 Their incidence varies widely from 5% to 56% in observational studies and trials using differing diagnostic criteria.108 WHO guidelines recommend a five-day course of oral antihistamines for those with serum-sickness type late reactions, and a five-day course of prednisolone in those who fail antihistamine therapy after the first two days.2425, Patients with persistent bleeding despite repeated antivenom treatment or having respiratory and renal failure may require urgent supportive measures such as blood transfusion, mechanical ventilation, and renal replacement therapy respectively.2425 If these are not available, arrange for transfer to a specialised centre. To treat a sting, call triple zero (000) for an ambulance and pour vinegar liberally over the tentacles on the persons skin for at least 30 seconds to deactivate the sting. All authors searched the literature, framed manuscript content, contributed to critical revisions and approved of the final version. No patients were involved in the creation of this article.

Mechanistic studies suggest that most events are not IgE mediated and thus cannot be accurately predicted by skin tests for immediate hypersensitivity.109 However, their incidence and severity can be reduced by a prophylactic subcutaneous injection of low dose adrenaline.108110 Pyrogenic reactions result from product contamination during manufacture.111, Nausea, vomiting, abdominal pain, and diarrhoea, Life threatening shock, bronchospasm, and angioedema108, These present with fever, rigors, and vasodilation with or without hypotension, Depending on the dose, speed of administration, and product quality, the risk of any early reaction varies from 3% to more than 80% in studies from Latin America and South Asia. Stonefish live all around the Australian coastline. Please enter manually below. Venom injection deep into a limb can cause tissue swelling in the tightly constrained space and compromise neurovascular function.5455 This manifests as acute compartment syndrome.242531, Bite siteSwelling, blistering, bruising, necrosis (usual after bites by cobras and vipers, with some exceptions in each family, and burrowing asps)2425, Acute compartment syndrome after deep bite into a limbIntense pain, abnormal sensations, or a cold, pulseless, immobile limb2425, Venom ophthalmia from entry of venom droplets or spray into the eyesIntense pain, redness, blepharitis, blepharospasm, and corneal erosions31, VascularEnvenoming by most viperid and Australopapuan elapid species and some non-front-fanged colubroids can trigger clotting failure, platelet abnormalities, and vessel wall damage.343536 Effects range from clotting test abnormalities to mild bite site or mucosal bleeds to severe spontaneous systemic or intracranial haemorrhage2425, ShockFrom bleeding or plasma extravasation systemically or into the swollen, bitten limb, myocardial dysfunction, pituitary bleeds, vasodilation, sepsis, and anaphylaxis2936373839404142, NeuromuscularMost elapid and some viperid venoms can cause paralysis by action at the nerve (presynaptic) or muscle fibre (postsynaptic) of the neuromuscular junction.2425 Weakness of eye muscles initially present as ptosis, diplopia, and blurred vision. Learn about symptoms, causes and prevention of snake bite. Details about the site, circumstances, and timing of the bite can reflect distinctive features of epidemiology, habitats, and periods of activity of medically important snakes locally and help infer likely biting-species.32425, Inquire about medications, substance use, and comorbidities as these can influence diagnosis and outcomes. It may develop within a few minutes to a few hours and may include: Bite or fang marks on arm or leg; there may be no pain or negligible pain and swelling at the bite site Call 13 11 26. Go to: Abstract Background: Sea snakes are venomous snakes found in the warm parts of the Indo-Pacific, including around Australia. Rural communities in tropical countries are worst affected.13141516 Agricultural workers, hunter-gatherers, herders, fishermen, and rural families living in precarious housing conditions with outdoor toilets have a higher risk of snakebite. When in the water, these snakes appear to have a pale yellowish hue. Usually, little or no swelling occurs, and rarely are any nearby lymph nodes affected. While they live in the oceans, sea snakes cannot extract fresh water from the saline sea. Nonvenomous snakebites cause only local injury, usually pain and 2 to 4 rows of scratches from the snake's upper jaw at the bite site. In some cases, this sensation increases and can cause intense symptoms for 2 to 3 days. Arrange for rapid transport to the nearest medical facility, preferably with access to antivenom and critical care support.60, Immobilise the person, and especially the bitten limb to slow venom spread.24 Remove rings and other tight objects around the limb.61 A systematic review identified pressure immobilisation with an elastic bandage or pad (at a comfortable pressure) at the bite site as an effective first aid measure to slow venom spread, but the quality of evidence was very low.6263 Its use is variable, and it is discouraged in most practice and guidelines because of the uncertainty of benefit and possibility of worsening local tissue damage.15296264656667 However, pressure immobilisation is generally recommended for neurotoxic elapid bites in some regions.68 Its clinical efficacy and risk of worsening soft tissue injury in local envenoming have not been adequately assessed.24296669 A small study (15 patients) in Myanmar found that pressure pads were effective in reducing venom spread in Russells viper bite, and local effects after pad application were no more severe than those before treatment.70, Tourniquets can cause severe local damage and gangrene and must not be used.2425 It is common for communities to resort to traditional therapies such as wound incisions, cauterisation, and application of herbs, minerals, or animal excrement. But it's important to get all snake bites checked as soon as possible. Sea Snake Bites.

Managing snakebite | The BMJ Bites from venomous snakes can result in bleeding, paralysis, long term disability, and death, Immobilise the bitten limb when transporting the patient to a medical facility; the universal use of pressure immobilisation is controversial, and tourniquets are not recommended, The 20-minute whole blood clotting test is a simple bedside test to screen for and monitor coagulopathy in resource-limited settings, Assess vital parameters and initiate resuscitation measures if the patient is clinically unstable with signs of bleeding, shock, paralysis, or respiratory distress, Intravenous antivenom is recommended in patients with systemic symptoms; the dose and type depend on likely snake species, local guidelines, and availability, Snakebite affects between 1.8 to 2.7 million people worldwide each year, and it is estimated to cause between 80000 and 138000 deaths.12 A mixture of toxins (venom) is injected into the body following bite by a venomous snake.3 Envenoming can be a highly dynamic clinical event. The mating behavior of the reptiles is unknown, but it may be linked to the occasional schooling of large numbers of snakes. Never substitute vinegar with methylated spirits or alcohol because they will make the sting worse. Venomous Sea Snake Facts (Hydrophiinae and Laticaudinae) - ThoughtCo Often bites are by non-venomous snakes.
