thy·ro·tox·ic cri·sis

, thyroid crisisthe exacerbation of symptoms of hyperthyroidism; severe thyrotoxicosis; can follow shock or injury or thyroidectomy; marked by rapid pulse (140-170/minute), nausea, diarrhea, fever, loss of weight, extreme nervousness, and a sudden rise in the metabolic rate; coma and death may occur; occasionally the entire clinical picture is that of profound prostration, weakness, and collapse, without the phase of muscular overactivity and tachycardia. Synonym(s): thyroid storm

thyrotoxic crisis

Thyroid crisis, thyrotoxic storm Endocrinology A hypermetabolic state superimposed on hyperthyroidism, often occurring in Grave's disease–especially if untreated, less common in toxic multinodular goiter, and rarely in Hashimoto's disease/Hashitoxicosis Etiology/'triggers' Infection–eg, streptococcal pharyngitis, thromboembolism, surgery, physical or mental stress, parturition, withdrawal from thyroid-blocking drugs Clinical Sx of hyperthyroidism–eg, weight loss, heat intolerance, myasthenia, ↓ concentration, CHF, PE, restlessness, diarrhea, diaphoresis, palpitations which, when accompanied by 'triggers,' become a life-threatening hypermetabolism, characterized by hyperthermia, tachycardia, cardiac, hepatic and cerebral dysfunction, death Lab ↑ T₄, ↑ T₃, ↓ cholesterol Management ↓ Hypermetabolism, inhibit T₃/T₄ release with iodine, block T₃/T₄ synthesis with propylthiouracil and other anti-thyroid agents, block adrenergic neurotransmission with beta blockers and glucocorticoids to 'cover' for functional hypoadrenalism.
