Potassium infusion CorrectCorrect
The history describes an episode of collapse in a patient with thyrotoxicosis. The likely cause of the collapse is thyrotoxic hypokalaemic periodic paralysis.
Episodes of hypokalaemic periodic paralysis occur in 10% of young Latin American or Asian men with thyrotoxicosis (of whatever aetiology). Acute attacks repond to potassium administration.
The periodic paralysis resolves when the thyrotoxicosis is treated.
