Caso de envenenamiento por picadura de pez león, atendido en un servicio de urgencias de Colombia

The lionfish (Pterois volitans) is an invasive species in the Caribbean Sea that can accidentally inject venom into humans through its spines. Here, we report a case of lionfish envenomation, highlighting a potential emerging threat to public health in Colombia. The case describes a healthy 59-year-old woman who suffered an accidental sting on the fourth finger of her left hand after contact with a lionfish spin while diving in Aruba.On-site treatment included hot compresses, antihistamines, and systemic corticosteroids. However, the patient experienced severe pain, coldness, and paleness in the affected finger. One day later, the patient traveled to Bogotá, Colombia, and developed swelling, loss of sensitivity, and changes in skin coloration. In the emergency unit, the patient received pharmacological treatment with 100 mg of aspirin administered orally and 60 mg of enoxaparin administered subcutaneously; also, a calcium antagonist was prescribed for vasospasm management (30 mg of nifedipine 30 administered orally), and complementary studies were ordered. Paraclinical results were normal, and the Doppler ultrasound of theleft upper limb arterial vessels showed no abnormalities. The treatment was successful, and the patient fully recovered.Given the novelty of this affection for our country, the patient’s favorable evolution after latestage pharmacological management, and the limitations of the initial treatment, we present a broad discussion based on the review of related literature.
