CONTEXT: Several species of medically important Australian elapid snakes are frequently involved in human envenoming. The brown snake group (Pseudonaja spp., 9 species) is most commonly responsible for envenoming including life-threatening or fatal cases. Several Pseudonaja spp. can inflict human envenoming that features minor local effects, but may cause serious systemic venom disease including defibrination coagulopathy, thrombocytopenia, micro-angiopathic hemolytic anemia (MAHA) and, rarely, paralysis...

This study investigated whether myocardial damage, as reflected by increased serum concentrations of cardiac-specific troponin I (cTnI), develops in dogs as a result of a bite from a common European viper (Vipera berus), and whether this damage occurs in the absence of clinically relevant ECG abnormalities. Twenty-four dogs presented following a snake bite were tested. On admission, and after 12, 24 and 36 hours, an ECG was recorded and serum was collected for analysis of cTnI from all the dogs. Thirteen dogs (54 per cent) had an undetectable serum cTnI concentration (<0...

BACKGROUND: Bungarus candidus (Malayan krait) snake is a neurotoxin snake. Previous treatment after snakebite was mainly respiratory support until the patient had spontaneous breathing. Recently specific antivenom for the Bungarus candidus snake was produced by the Queen Saovabha Memorial Institute and distributed in June 2004. The present article is the first report on the clinical response to the specific antivenom for Bungarus candidus. OBJECTIVE: To analyze the signs and symptoms of patients after snakebite and the response of the patients after receiving specific antivenom for Bungarus candidus snake...

Various clinical manifestations leading to death have been documented in most cases of bites caused by venomous snakes. Cobra envenomation is an extremely variable process and known to cause profound neurological abnormalities. The complexity of cobra venom can induce multiple-organ failure, leading to death in case of severe envenomation. Intramuscular administration of Malayan spitting cobra (Naja sputatrix) crude venom at 1 microg/g dose caused death in mice in approximately 3 h. Analysis of gene expression profiles in the heart, brain, kidney, liver and lung revealed 203 genes whose expression was altered by at least 3-fold in response to venom treatment...

The only venomous reptile that naturally occurs in Poland is the adder or common viper (Vipera berus). Its bites are not of great epidemiological importance, but in some cases serious life-threatening symptoms may appear. The most common symptoms of adder envenomation are: local edema, reddening and pain of the bitten site and also the general symptoms coming from the alimentary tract (vomiting, diarrhoea, abdominal pain), the circulatory system (hypotension, shock, ECG abnormalities), the central nervous system (sleepiness, vertigo, disorientation, loss of consciousness), hematological symptoms (leukocytosis, hemolysis, coagulopathy) and allergic symptoms (fever, urticaria, angio-oedema)...

INTRODUCTION: Cardiac effects following the bite of Burmese Russell's vipers and European vipers are well known. The question whether envenomation caused by Sri Lankan viper bites results in myocardial damage remains largely unanswered. The aim of this prospective study was to investigate whether myocardial damage occurs after Sri Lankan viper bites, using a highly specific and sensitive marker, troponin T. METHODS: 45 patients admitted after a definite viper bite [Russell's viper (RV), n = 13, hump-nosed viper (HNV), n = 32] were studied with regard to cardiac symptoms, ECG changes, and troponin T levels...

During routine milking of a group of Burrowing Asps Atractaspis engaddensis, one of the authors was bitten in the index finger by one fang, as is characteristic of bites by snakes of the genus. Local effects, oedema, erythema and numbness appeared within minutes, followed by systemic effects, including general weakness, sweating, pallor, fluctuations in the level of consciousness, vomiting and watery non-bloody diarrhoea. Gross oedema of the hand developed and extended up to the forearm. Two hours after admission to the hospital, blood pressure rose to 180/110, the ECG showed normal sinus rhythm and no signs of atrioventricular conduction block...

Five cases of adder bites are presented. The clinical effects and current recommendations for the treatment of adder bites are described based on a review of previously published literature. All adder bites, or snake bites of unknown species, should be observed for a minimum of 2 h. Those with no local swelling may be allowed home with appropriate antitetanus prophylaxis. Patients with local reaction or signs of systemic envenoming should be admitted for 48 h with ECG monitoring, and antivenom obtained. Indications and precautions for administration of antivenom are reviewed...

Cardiac disease developed several days to weeks after resolution of local inflammation caused by envenoming by Vipera palaestinae in two horses. In one horse (case A), referred to the hospital for recurrent abdominal pain 8 days after envenoming, a tachyarrhythmia was detected; ventricular premature depolarizations were diagnosed by ECG. A second horse (case B) was found dead without premonitory signs 60 days after envenoming. In both horses, there was extensive necrosis of cardiac ventricular tissues.

Two cases of bites by the common viper were reviewed. Emphasis was focused on proper medical monitoring in an intensive care unit for a minimum of one day. Observations should include ECG, Hb, leucocytes, electrolytes in both blood and urine, CPK, and coagulation factors. Surgical intervention, heparin and cryotherapy are not recommended. Proper treatment with immobilisation of the bitten extremity, tetanus antitoxin and volume therapy is recommended. In severe cases Zagreb Antitoxin should be used. Patients with cardio-pulmonary problems require special attention...

Evenomation by the common European adder (Vipera berus) is well known for its significant morbidity but low mortality. Cardiac complications tend to take second place to the systemic upset and usually only comprise non-specific ECG changes. This case illustrates many of the classical features of adder bite but it is also the first account of heart block as a complication.
