Bloqueo del nervio ciático poplíteo ecoguiado en urgencias en un paciente pediátrico con dolor severo producido por una picadura de escorpión / Ultrasound-guided sciatic popliteal block performed at the Emergency Department in a patient with a scorpion bite and severe pain

Presentamos el caso de un paciente pediátrico que acudió a urgencias con dolor severo en la extremidad inferior derecha causado por la picadura de un escorpión. Ante la ausencia de respuesta a los analgésicos administrados se optó por realizar un bloqueo poplíteo ecoguiado, lo que consiguió una analgesia completa y permitió el manejo ambulatorio del paciente, sin referir efectos adversos. Las familias de escorpiones presentes en nuestro país no suponen un riesgo vital para el ser humano, pero su picadura produce una reacción local con dolor autolimitado a unas 24-48h que puede ser severo. El manejo prioritario es realizar una correcta analgesia. Las técnicas anestésicas regionales son de utilidad para el control del dolor agudo y pueden representar una colaboración eficaz entre los servicios de anestesiología y urgencias.(AU)

We report the case of a paediatric patient who presented at the Emergency Department with severe pain in the right lower extremity caused by a scorpion sting. Analgesics were ineffective, so we decided to perform an ultrasound-guided popliteal block. This, which achieved complete analgesia and allowed the patient to be followed up in the outpatient department, with no adverse effects. The sting of the species of scorpion found in Spain is not dangerous to human life; however, it causes self-limiting localised pain that lasts for 24-48hours, and can be severe. The first-line treatment is effective analgesia. Regional anaesthesia techniques are useful in the control of acute pain, and are an example of effective collaboration between the Anaesthesiology and Emergency services.(AU)
