Insights
Severe snakebite envenomation in a child caused coagulopathy and anemia. Therapeutic plasma exchange stabilized the patient when conventional treatments failed, preserving limb function.
Area of Science:
- Toxicology
- Pediatric Hematology
- Emergency Medicine
Background:
- Snakebite envenomation is a significant global health issue, particularly in rural areas.
- Hemotoxic snakebites can cause life-threatening coagulopathy, hemolytic anemia, and compartment syndrome.
- Pediatric cases present unique challenges due to smaller body mass and potential for rapid deterioration.
Purpose of the Study:
- To report a case of severe hemotoxic snakebite envenomation in a child.
- To highlight the effectiveness of therapeutic plasma exchange (TPE) in refractory pediatric cases.
- To discuss the management of compartment syndrome in the context of uncontrolled coagulopathy.
Main Methods:
- Case report of a 6-year-old boy with severe hemotoxic snakebite.
- Initial management included antivenom and supportive transfusion therapy.
- Subsequent treatment involved five sessions of therapeutic plasma exchange due to persistent deterioration.
- Conservative management of suspected compartment syndrome was employed due to high bleeding risk.
Main Results:
- The patient developed venom-induced consumption coagulopathy, hypofibrinogenemia, thrombocytopenia, and microangiopathic hemolytic anemia.
- Antivenom and transfusions were insufficient to correct coagulopathy and anemia.
- Therapeutic plasma exchange led to stabilization of hematologic parameters and resolution of limb swelling.
- Limb function was preserved without surgical intervention for compartment syndrome.
Conclusions:
- Therapeutic plasma exchange is a valuable treatment for pediatric snakebite envenomation unresponsive to conventional therapies.
- Conservative management of compartment syndrome may be appropriate in high-risk bleeding scenarios.
- Early recognition, multidisciplinary care, and advanced treatments like TPE are crucial for complex pediatric envenomations.
Abstract:
Snakebite envenomation is a global public health concern, and hemotoxic bites can lead to severe coagulopathy, microangiopathic hemolytic anemia, and compartment syndrome. We describe a previously healthy 6-year-old boy who presented with progressive left lower limb swelling, discoloration, and bleeding from intravenous cannula sites following a snakebite sustained in rural Pakistan, consistent with severe hemotoxic envenomation. Despite antivenom and transfusion support, he developed persistent venom-induced consumption coagulopathy with hypofibrinogenemia, markedly prolonged clotting times, thrombocytopenia, and features of microangiopathic hemolytic anemia. Severe limb swelling raised concern for compartment syndrome; however, fasciotomy was deferred due to the high risk of bleeding in the setting of uncontrolled coagulopathy. Transferred to Bahrain, he underwent five sessions of therapeutic plasma exchange, initiated due to ongoing clinical and laboratory deterioration, resulting in stabilization of hematologic parameters, resolution of limb swelling, and preservation of limb function. This case highlights the role of plasma exchange in children unresponsive to conventional therapy and demonstrates that conservative management of suspected compartment syndrome may be feasible when surgical intervention carries significant risk, underscoring the importance of early recognition and multidisciplinary care in complex pediatric envenomation.
