In this episode of PICU Doc On Call, Dr. Pradip Kamat and Dr. Rahul Damania discuss a case of a 4-year-old girl with bite marks and swelling of her foot, presenting with concerning vital signs and abnormal labs. They explore snake envenomation and its management in the pediatric critical care setting.
Classifying Snake Envenomation
Snakes with venom-delivering fangs, primarily Elapidae and Viperidae, are responsible for most human envenomations and fatalities. We're focusing on Pit Vipers today, including rattlesnakes, cottonmouths, and the copperhead. Elapids, such as the coral snake, differ by having round pupils, short fangs, and no facial pit.
Risk Factors for Pediatric Snakebites
Snakebite incidents can happen when toddlers unintentionally disturb snakes, particularly in low-light conditions or grassy areas. Teenagers trying to capture snakes are another frequent group presenting with upper extremity bites.
Pathophysiology of Snake Envenomation
Snake venoms contain toxic proteins that affect various physiological systems, leading to neurotoxic, hemotoxic, myotoxic, or cytotoxic effects. Envenomation can happen immediately or be delayed, presenting with various clinical and laboratory anomalies.
Syndromes Observed After Snake Envenomation
The impact of a snakebite depends on the snake type, fang size, and venom injection site. Effects may include cytotoxicity, lymphatic system damage, platelet dysfunction, neurotoxicity, cardiotoxicity, hypotension, and nephrotoxicity.
General Management Framework
In snakebite cases, prehospital care involves immediate EMS call and ensuring airway, breathing, and hemodynamic stability. In the hospital, general supportive care is crucial, and antivenin administration depends on clinical presentation and snake type.
Antivenin Considerations
Antivenin dosage is challenging due to unknown venom load, and its choice depends on safety, kinetics, cost, and the specific snake involved. Smaller fragments of antivenin have larger distribution volumes and shorter half-lives. Recurrence, anaphylaxis, and serum sickness are potential side effects of antivenin.

Research Findings
A 2022 CHEST study by Khemani et al. on children with bronchiolitis challenged the conventional understanding of HFNC's mechanisms.
HFNC primarily reduces breathing effort but does not consistently increase lung volume (EELV) or tidal volume (VT).
Reduction in the pressure rate product (PRP) indicates decreased breathing effort, but not significant alterations in EELV or VT.
Physiological Effects
HR, RR, and SpO2 are key indicators of HFNC efficacy.
HR and RR should approach normal ranges for the child's age.
Improvement in SpO2 levels while maintaining or reducing FiO2 indicates a positive response.
Conclusion
HFNC is a valuable tool in pediatric care for alleviating respiratory distress.
Not a one-size-fits-all solution; vigilant monitoring and reassessment are crucial
Recognizing HFNC's mechanisms allows for optimized bedside application.

Acute rheumatic fever is an autoimmune disease initiated by a response to group A strep infection, primarily due to molecular mimicry. The streptococcal M protein has structural similarities with host proteins, leading to organ damage, especially in the heart.
Epidemiology:
Acute rheumatic fever is most prevalent in low to middle-income areas, affecting over 80% of cases. It mainly affects children between 5 to 14 years of age, and overcrowded households and limited healthcare access increase the risk. Globally, rheumatic heart disease affects millions of people annually and claims many lives.
Jones Criteria for Diagnosis:
The Jones criteria help diagnose acute rheumatic fever. For a definitive diagnosis, evidence of a preceding group A strep infection is required. Major manifestations include carditis, arthritis, erythema marginatum, subcutaneous nodules, and Sydenham's chorea. Minor criteria include fever, elevated inflammatory markers, prolonged PR interval on EKG, and mild joint issues.
Differentiating Low and High-Risk Populations:
The criteria differentiate between low and high-risk populations based on the epidemiology of acute rheumatic fever. The presentation of arthritis varies, and the thresholds for fever or inflammatory marker elevation are lower in high-risk populations.
Diagnostic Approach:
Diagnosis includes throat swab, anti-streptolysin O antibody titers, anti-DNAse B titers, CBC with differential, blood cultures, inflammatory markers, EKG, chest X-ray, and echocardiography. Joint analysis may be performed if needed.
Sydenham's Chorea:
Sydenham's chorea is marked by involuntary movements, primarily in the trunk and limbs, and it often resolves within 12 to 15 weeks with treatment.
Management of Acute Rheumatic Fever:
Management includes eradicating the remaining strep infection, controlling inflammation, and preventing recurrence. Penicillin or amoxicillin is used to treat the infection, while aspirin or NSAIDs are used to manage inflammation. In severe cases, systemic steroids may be considered. Cardiac surgery should be delayed until acute inflammation resolves. Prophylactic antibiotics are used for prevention.
Conclusion:
Rheumatic fever management requires a holistic approach, encompassing infection control, inflammation management, and long-term prevention. Early recognition, thorough diagnostics, and prophylactic antibiotics play essential roles in managing this condition.
Future Directions:
Research is needed for early detection using biomarkers and the development of a group A strep vaccine.
