Diagnosis and treatment of confirmed and suspected snake bite. Implications from an analysis of 46 paediatric cases

Area of Science:

• Medical Research
• Toxicology
• Pediatric Emergency Medicine

Background:

• Snake bites are a significant concern, particularly in regions like southern mainland Australia.
• Accurate identification of envenomation is crucial for timely and appropriate medical intervention.
• Current diagnostic and treatment protocols require ongoing evaluation for effectiveness.

Purpose of the Study:

• To determine reliable predictors of snake envenomation in pediatric patients.
• To assess the effectiveness of current treatment standards for envenomed children.
• To improve clinical management and first aid education for snake bites.

Main Methods:

• Retrospective cohort analysis of 46 children with suspected or confirmed snake bites (1979-1990).
• Envenomation confirmed by snake venom detection in blood or urine.
• Evaluation of clinical symptoms, venom tests, and coagulation profiles.

Main Results:

• Of 46 children, 19% were envenomed, with two fatalities due to coagulopathy.
• Headache, abdominal pain, and vomiting showed moderate predictive value for envenomation.
• Coagulopathy demonstrated 100% sensitivity, specificity, and predictive value for envenomation.

Conclusions:

• Clinical symptoms like headache, abdominal pain, and vomiting, alongside abnormal coagulation tests, are accurate indicators of snake envenomation.
• The study highlights the need for improved first aid and clinical management education for snake bites.
• Effective management strategies, including antivenom administration and appropriate pre-medication, are critical.
