What is the primary intervention administered by medical teams upon hospital arrival for patients with severe toxicity from box jellyfish stings?
Administration of the specific box jellyfish antivenom
Once a patient suffering from a severe box jellyfish sting reaches a hospital setting, medical professionals immediately prioritize stabilizing vital functions, especially monitoring heart function and respiration. If the patient exhibits signs of severe systemic toxicity, such as life-threatening cardiac arrhythmias, respiratory distress, or actual collapse, the paramount intervention is the immediate administration of the specific antivenom developed for the most dangerous species involved. This antivenom has the potential to actively reverse cardiac morbidity and significantly alleviate associated pain, often showing initial positive effects within about 15 minutes of injection, alongside supportive oxygen therapy for respiratory issues.
