Overview
Snake venom-induced myelopathy refers to a neurological complication resulting from snake envenomation, characterized by spinal cord damage leading to motor and sensory deficits 1.Diagnosis
Clinical presentation includes progressive weakness, sensory loss, and potential paralysis 1.
Imaging studies such as MRI may reveal spinal cord edema or demyelination 1.
Electromyography (EMG) and nerve conduction studies can help assess the extent of nerve damage 1.
Laboratory tests may show elevated inflammatory markers or venom-specific antibodies 1.Management
Supportive care including immobilization and monitoring of respiratory function is crucial 1.
Antivenom therapy is often considered but its use can vary based on clinical context 1.
Corticosteroids may be administered to reduce inflammation and edema in the spinal cord 1.
Pain management with appropriate analgesics is essential 1.
Rehabilitation, including physical and occupational therapy, should be initiated early 1.Special Populations
Pregnancy: Treatment without antivenom has shown success, emphasizing conservative management approaches 1.Key Recommendations
Prioritize supportive care and monitoring in patients with snake venom-induced myelopathy (Evidence: Weak) 1.
Consider corticosteroid therapy to manage inflammation and spinal cord edema (Evidence: Weak) 1.
In pregnant women, conservative management without antivenom can be effective; individualized treatment plans are advised (Evidence: Expert opinion) 1.References
