Venomous snakebites in children and adolescents: a 12-year retrospective review
Journal of Venomous Animals and Toxins, 2001
Snakebite envenomation is a worldwide problem and in Costa Rica. The following is a retrospective review of 79 patients admitted to the Hospital Nacional de Niños (HNN) from January 1985 to September 1996. Child's age ranged from 9 months to 14 years. The M: F ratio was 1.5:1. Sixty percent of the patients lived in remote rural areas. The most common clinical signs at the time of hospitalization were pain and edema. Fifty patients (63,29%) showed moderate to severe envenomation grades. Fifty-one (64,55%) was caused by Bothrops asper. Complications during hospitalization were compartment syndrome and secondary infection. Three children died, one from disseminated intravascular coagulation, another from renal insufficiency, and the third from a perforated duodenal ulcer. Patients who underwent early fasciotomy had significantly less hospitalization and fewer infectious complications, (p < 0.001). There was no relationship between the envenomation grade and length of hospitalization (p = 0.4). The most common pathogen isolated was S. aureus.
Snake Bites: A Public Health Problem Present
International Journal of Innovative Science and Research Technology, 2020
This article shows the results of a retrospective analysis study, 2018-2019, with the aim of clinically and epidemiologically characterizing patients with snake bite accidents treated at Huixtla General Hospital, Chiapas, Mexico. The universe of study consists of No. 43 patients. The variables were studied: age, sex, occupation, time of aggression, place and time of aggression, clinical picture, hematological alterations, neurotoxic alterations, type of snake and laboratory studies. Snakebite is a significant occupational risk, especially for field workers, to whom prevention-focused educational campaigns should be run. Appropriate provision of anti-crotalic serum is recommended in hospitals located in risk areas and deepen the formation of health servers in these areas.

Introduction: Snakebites in the Brazilian Amazon are caused mostly by snakes from the Bothrops genus and envenomated patients may suffer from tissue complications. Methods: This study aimed to identify risk factors for severe tissue complications (STC) in patients with Bothrops snakebite in the Amazonas state, Brazil. Results: Snakebites that were classified as severe and affected female patients with comorbidities presented greater risks of developing STCs. In addition, hospitalizations of patients with STC exceeded 5 days. Conclusions: Clinical and epidemiological characteristics can prove essential for assessing the evolution of STC and clinical prognosis of patients with Bothrops snakebites.
Snakebites by Bothrops spp in children in Campinas, São Paulo, Brazil
Revista do Instituto de Medicina Tropical de São Paulo, 2001
, 73 children under 15 y old (ages 1-14 y, median 9 y) were admitted after being bitten by snakes of the genus Bothrops. Twenty-six percent of the children were classified as mild envenoming, 50.7% as moderate envenoming and 20.6% as severe envenoming. Two patients (2.7%) showed no signs of envenoming. Most of the patients presented local manifestations, mainly edema (94.5%), pain (94.5%) ecchymosis (73.9%) and blisters (11%). Local and/or systemic bleeding was observed in 28.8% of the patients. Before antivenom (AV) administration, blood coagulation disorders were observed in 60.7% (incoagulable blood in 39.3%) of the 56 children that received AV only in our hospital. AV early reactions, most of which were considered mild, were observed in 44.6% of these cases (in 15/30 patients not pretreated and in 10/26 patients pretreated with hydrocortisone and histamine H 1 and H 2 antagonists). The main clinical complications observed were local infection (15.1%), compartment syndrome (4.1%), gangrene (1.4%) and acute renal failure (1.4%). No deaths were recorded. There were no significant differences with regard to severity of envenoming versus the frequency of blood coagulation disorders among the three categories of envenoming (p = 0.75) or in the frequency of patients with AV early reactions between the groups that were and were not pretreated (p = 0.55). The frequency of local infection was significantly greater in severe cases (p < 0.001). Patients admitted more than 6 h after the bite had a higher risk of developing severe envenoming (p = 0.04).

Oral cavity bleeding following snakebite: A case report
Research, Society and Development, 2021
Snakebite is an important public health problem because of its incidence, morbidity, and mortality. It may be related to climatic factors and rural habits. Snakes of the genus Bothrops are responsible for most snakebites in Brazil. The venom of these snakes has peculiar characteristics, with important proteolytic, coagulant, and hemorrhagic actions, leading to local and systemic alterations. Initial manifestations include local tissue injury, pain, swelling, bleeding, and bullous lesions that can progress to abscesses or tissue necrosis. Systemic manifestations should be carefully evaluated especially for the probability of hemorrhagic events such as epistaxis, gingivorrhagia, hematuria, and hemoptysis. Knowing the clinical manifestations of snakebites, as well as the adequate treatment, is essential. Efficient and rapid diagnosis can minimize victims’ injuries and the probability of death. The present study reports the clinical case of bleeding at a distant site from the initial si...

Snake bite is a common but under-reported medical emergency accounting for 0.5% of all deaths with greater risk of fatal envenomation in children. In India, four species of venomous snake are most common but better classification of medically significant species is warranted. Snake venom is a mixture of peptides with enzymatic & toxic properties which mediate activation of cytokine cascades along with organ specific toxicities, manifesting into local and systemic symptoms. The syndromic approach of attributing a constellation of signs & symptoms to a particular family of venomous snake has clinical acceptance but overlaps exist. Management of snake bite victim starts with a first aid measures of reassurance, immobilization and quick transfer to hospital. Measures such as application of tourniquet, incision and suction are harmful & should not be done. On arrival at hospital, triage and stabilization of Airway, Breathing & Circulation (ABC) is done followed by a focused assessment to ascertain the severity of envenomation. Antivenom treatment is the mainstay of snake bite management. ASV should be started only when specific indications such as signs of neurotoxicity, coagulopathy, hypotension, hematuria are present. Indiscriminate use of ASV is strongly condemned. Currently 8-10 vials of ASV as initial dose with a maximum of 25 vials is recommended. There is no role of test dose of ASV. Measures to treat any ASV induced anaphylaxis should be ready prior to start of ASV treatment. Supportive treatment is as important in determining the final outcome of envenomation as ASV.
Snakebites on Distal Extremities; Three Years of Experiences
Zahedan Journal of Research in Medical Sciences
Background: Globally, 1.5 to 3 million people are exposed to snakebites each year. More than 100,000 of these cases, primarily in the tropics, result in death. This study includes an analysis of a university hospital's three-year experiences of distal extremity snakebites. Methods: This study includes 68 patients presented at the Emergency Department (ED) of Gaziantep University Hospital with snakebites on distal extremities (hands, fingers, and feet) between 01/03/2014 and 01/03/2017. Results: A total of 68 patients had wet snakebites on their distal extremities. Forty-seven patients (69%) were male, 21 (30.9%) were female, and the mean age was 43.03 ± 18.13 years. Snakebites most commonly occurred in September (26.5%, n = 18). Twenty-five (36.76%) patients had systemic symptoms (grades 2, 3, and 4). Also, 98.5% (n = 67) of patients received only antivenom therapy. Compartment syndrome was observed in one patient (1.5%), and this patient was treated with antivenom therapy and p...

Background: Bothrops envenomations can often lead to complications, such as secondary infections. Methods: This cross-sectional study analyzed the medical records of all patients diagnosed with snakebite. Results: A total of 127 patients were included. Clindamycin was the most commonly prescribed antibiotic, with 105 patients (82.7%) receiving it as the primary antibiotic regimen. In 31 (24.4%) individuals, the first-choice antibiotic did not cease the infection. Conclusions: Secondary infection is an important complication resulting from snakebites, and evidence-based management of this complication can contribute to better clinical outcomes.
