Non-venomous snake bite and snake bite without envenoming in a Brazilian teaching hospital. Analysis of 91 cases.

A retrospective survey of 473 cases of snake bite admitted to a Brazilian teaching hospital from 1984 to 1990 revealed 91 cases of bite without envenoming and/or caused by non-venomous snakes. In 17 of these cases the snake was identified, and one patient was bitten by a snake-like reptile (Amphisbaena mertensii). In 43 cases diagnosis was made on clinical grounds (fang marks in the absence of signs of envenoming). The other 30 cases were of patients who complained of being bitten but who did not show any sign of envenoming or fang mark. Most cases occurred in men (66;73%), in the 10-19 years age group (26;29%), in the lower limbs (51/74;69%), between 6 A. M. and 2 P.M. (49;61%) and in the month of April (16;18%). One patient bitten by Philodryas olfersii developed severe local pain, swelling and redness at the site of the bite, with normal clotting time. The patient bitten by Drymarcon corais was misdiagnosed as being bitten by a snake of the genus Bothrops, was given the specific antivenom, and developed anaphylaxis. One patient bitten by Sibynomorphus mikanii presented prolonged clotting time, and was also given antivenom as a case of Bothrops bite. Correct identification of venomous snakes by physicians is necessary to provide correct treatment to victims of snake bite, avoiding unnecessary distress to the patient, and overprescription of antivenom, which may eventually cause severe untoward effects.

Intensive care unit treatment of acute renal failure following snake bite.

Twenty-nine patients with acute renal failure following bites by snakes of the genera Crotalus and Bothrops were treated in an Intensive Care Unit (ICU). Eight were given conservative treatment. Peritoneal dialysis was necessary in 21 patients, and hemodialysis in one of these. The main complications occurring while the patients were in the ICU were pulmonary edema (5 cases), respiratory failure (4), cardiac arrest (4), and hypovolemic shock (1 case). Three patients died with respiratory and hemodynamic disturbances while in the ICU, one of them during the polyuric phase. Twenty-four patients were discharged from the hospital with no clinical or laboratory evidence of renal failure. Two patients developed bilateral cortical necrosis of the kidney. One of them died in the general ward after interruption of dialysis and the other was discharged from the hospital with chronic renal failure. It was not possible to perform a kidney transplantation. The importance of the ICU in the recovery of such patients is stressed.

Human snake bite victims: the successful detection of circulating snake venom by radiommunoassay,.

A new solid-phase radioimmunoassay has been developed which allows positive identification of the type of snake venom in human tissue and fluids and its accurate quantitation. Tiger snake venom at a level of 210 ng/ml was detected post mortem in the serum of a child, and brown snake venom was detected in two adults bitten by unidentified snakes. Apart from forensic applications, the assay will be useful in studying clinical aspects of envenomation and the use of antivenenes.

Incidence, clinical manifestation and general management of snake bites.

There are regional patterns in snake-bites. Bites by cobras have a high incidence in Thailand and in the Philippines with a high case fatality rate. Among the venomous snakes of haemorrhagic nature, bites by Trimeresurus species such as green pit viper, Taiwan habu and Taiwan bamboo viper are important in Thailand and Taiwan for their high incidence of bite, although the case fatality rates are low. Bites by Malayan pit vipers are also important in Thailand and Malaysia because of their high incidence. Bites by sea snakes are more common in Malaysia than in the Philippines and Thailand.

[Poisonous-snake bites. Therapy and preventive measures].

It is estimated that every year about 500 000 people around the world are bitten by poisonous snakes. Between 30 000 to 50 000 persons die due to snake-bites; the highest frequency is reported from Southern Asia. Clinically three types of snake-bites can be distinguished: 1. Bites with local damage (extreme pain, edema, necrosis), 2. Bites followed by generalized hemorrhagic symptoms and 3. bites with neurotoxic effects of the poison (no local pain, paralysis of cerebral nerves, coma). For tropical snake-bites snake-venom is live-saving. As in many cases the biting animal cannot be identified it is advisable to use polyvalent sera. These are heterologous sera which contain antitoxins against several poisonous snakes of a certain area. Often there is some delay until the snake-venom becomes available. Therefore local and symptomatic treatment is valuable: cleaning of the wound, superficial incision to remove poison, venous congestion, oral and intravenous fluid-therapy, antihistaminic drugs, steroids and prophylaxis of shock. Tourists are only rarely endangered by poisonous snakes, they do not need to carry anti-snake venom; this is recommended for scientific excursions in areas with dense vegetation and for persons living in warm countries.

Snake bite in cats.

In 6 years snake bite was diagnosed in 41 cats, with an average age of 20 months. The commonest presenting signs were dilated pupils, absence of the pupillary light reflex, depression and generalised muscle weakness. Other frequent findings were vomiting, dyspnoea, hindlimb ataxia and complete flaccid paralysis. Thirty-seven cases (90%) occurred in the 6 warmer months of the year. Tiger snakes were positively identified in 7 cases. A recovery rate of 89% was obtained in cases receiving 3000 units Tiger snake antivenene, fluid therapy and nursing. Cases presenting with a complete flaccid paralysis and sub-normal temperatures were poor prognostic risks.

Echis colorata bites in Israel: an evaluation of specific antiserum use on the base of 21 cases of snake bite.

Specific Antiserum for Echis colorata snake bite has been in use since 1965. To date 25 cases of bite by this snake have been reported, most of which are included in this series. As the antiserum was not routinely used I had the opportunity to compare the results in patients receiving antiserum to the results in patients not receiving it. The conclusion is that the use of specific antiserum should be limited to patients demonstrating severe bleeding and not reacting to treatment of consumption coagulopathy. The clinical picture, laboratory results and the post mortem results of a fatal case of E. colorata bite are included.

Snake bite in dogs.

In 7 years snake bite was diagnosed in 80 dogs. Sporting breeds figured prominently. The average was 3.6 years. The commonest presenting signs were salivation, vomiting, dilated pupils, absence of the pupillary light reflex, depression and generalised muscle weakness, hindlimb ataxia and respiratory distress. Sixty-seven cases (84%) occurred in 6 warmer months on the year. Fifty-one dogs (64%) were seen either to be bitten or in contact with a snake. Tiger and Brown snakes were implicated on 32 and 3 occasions respectively. An overall recovery rate of 87% was obtained for patients receiving antivenene, fluid and support therapy. The period from treatment-to-full recovery was shorter for cases in which the bite-to-treatment period was one hour or less (24 hours) when compared with the recovery time for all cases (36 hours). The prognosis was poor for dogs presenting with the triad of complete flaccid paralysis, dyspnoea and a sub-normal temperature.

Epidemiology of sea-snake bites.

Epidemiological features as reflected by 101 patients with unequivocal sea-snake bite received in north-west Malaya are reviewed. Enhydrina schistosa caused over half the bites, including seven of the eight fatal bites. It is the most dangerous sea-snake to man. Over 90 per cent of the victims were male and 80 of the 101 patients were fishermen bitten at their job. Most victims were bitten on the lower limb through treading on the snake, and this resulted in more cases of serious poisoning than upper limb bites (caused through handling nets, sorting fish and so on). Only 14 cathers were bitten (through treading on the sea-snake; no bathers were bitten while swimming). In patients coming to hospital more than six hours after the bite, there was a four-fold increase in serious poisoning compared with patients coming within six hours of the bite. Thus, as time elapses after the bite, the victim is less likely to seek medical help unless poisoning is severe. Despite the lethal toxicity of sea-snake venom, in patients seen during 1957-61 before sea-snake antivenom became available, the mortality was only 10 per cent. Trivial or no poisoning followed in 80 per cent of the bites. On the other hand, of 11 patients (20 per cent) with serious poisoning, over half (six patients) died despite supportive hospital treatment. These epidemiological features observed in Malaya probably apply to most fishing folk along Asian coastlines where sea-snakes abound. If this is so, sea-snake bite must be a common hazard feared by millions of fishing folk, and a common cause of illness and death. But it is unlikely that the extent of this problem will be revealed to orthodox medicine for many decades because most fishing villages are far from medical centres; and even if hospitals or medical centres are available, fishing folk are usually reluctant to attend them. Only one species of sea-snake, Pelamis platurus, extends to the east coasts of Africa and west coasts of the tropical Americas, but for various reasons this species does not appear to constitute much of a hazard to fishing folk in these areas. Although bathers are occasionally bitten along Asian coasts, when they inadvertently tread on a sea-snake, the risk of sea-snake bite in this area is extremely low. The prevention of sea-snake bite and poisoning is considered. Highly effective antivenom is now available for treating victims with serious poisoning; death should not occur provided adequate medical treatment is given within a few hours of the bite. The main problem is provision of adequate medical care at rural medical centres and overcoming the reluctance fishing folk often have in attending these centres.

Snake bite in Australia--the problems involved and a protocol for hospital management.

Despite a great deal of original research into Australian snakes and their complex venoms, there is still confusion about the correct first-aid and hospital management of the bitten patient. This review illustrates the difficulties in diagnosis and treatment and presents a well tried protocol for the successful management of snake bite.

Renal failure following snake bite. A clinicopathological study of nineteen patients.

Clinical, hematological, and renal biopsy findings in 19 unselected patients with renal failure following snake bite, including eight bitten by Russell's viper, are presented. Hematological findings were variable and did not influence treatment. Renal histology was a good guide to prognosis; patients with normal histology recovered with conservative management, those with tubular necrosis responded well to dialysis, while those with cortical necrosis responded only partially. Peritoneal dialysis was found to be an adequate form of treatment in the majority of patients.
