Life-threatening inpatient endocrine emergencies can occur due to hormonal imbalances, and it’s essential to master the metabolic chaos of these true emergencies. A session at SHM Converge discussed cases where adrenal, thyroid, and pituitary abnormalities can lead to life-threatening emergencies, which are rare but have high stakes due to raised mortality.
One key message from the session was to treat the patient and not the number, as a thyroid-stimulating hormone level or cortisol level does not define the severity of the illness. Pattern recognition and clinical acumen are indispensable tools for diagnosis.
Acute Post-Operative Hypocalcemia
Dr. Ackermann presented a case of a patient who developed carpopedal spasm, perioral paresthesia, and a facial twitch after total thyroidectomy. Hypocalcemia is a common complication after total thyroidectomy, occurring in 20% to 50% of patients within 24 to 72 hours.
Severe hypocalcemia can occur in 5% to 6% of patients post total thyroidectomy, with the highest risk in patients with Graves’ disease. Acute management includes treatment with 100 to 300 mg of IV calcium gluconate over five to 10 minutes, then a calcium drip while monitoring levels every four to six hours.
Thyroid Emergencies: Not Just the TSH Level
While checking an inpatient’s thyroid-stimulating hormone level can be necessary, it can be misleading, as the level does not correlate with the severity of illness. Myxedema coma has a mortality rate of 60%, making diagnosis critical.
A diagnostic scoring system for myxedema coma can help score patients on thermoregulatory dysfunction, central nervous system effects, gastrointestinal findings, a precipitating event, cardiovascular dysfunction, and metabolic disturbances. Treatment should be started urgently with 100 mg of IV hydrocortisone every eight hours after adrenal hormone levels are drawn.
Adrenal Insufficiency
Adrenal insufficiency typically presents with non-specific symptoms, including fatigue, depression, nausea, vomiting, and abdominal pain. An evolving crisis may add metabolic abnormalities, and an adrenal crisis can lead to fever, anorexia, shock, and cardiovascular collapse.
For acute adrenal crisis, hormonal testing with adrenocorticotropic hormone (ACTH) and cortisol should be performed. Initial treatment consists of a bolus of hydrocortisone 100 mg IV with an additional 200 mg IV over the following 24 hours in divided doses.
Endocrine Perioperative Considerations
Endocrine emergencies should delay surgery unless the surgery is emergent and a life-or-death scenario. For minor and moderate abnormalities, considerations include subclinical hypothyroidism, overt hypothyroidism, subclinical hyperthyroidism, and overt hyperthyroidism.
Perioperative management is a common consult for hospitalists, and endocrine disease should be optimized prior to elective surgeries. Discharge planning is also important to prevent the next emergency, with patient education and social work support being essential components.
Early recognition and treatment are necessary to help prevent mortality, and treating the patient and not the number is essential. A post-operative parathyroid hormone test can guide the risk of hypocalcemia, and tools for hypothyroidism and hyperthyroidism can identify the risk for critical illness.
According to the report, patients with endocrine emergencies require careful management and follow-up to prevent complications. The endocrine system is complex, and emergencies can arise from various hormonal imbalances, as seen in cases of hormone crises in hospitals.
Dr. Ackerman’s session highlighted the importance of a detailed approach to managing endocrine emergencies, considering the patient’s overall condition and optimizing treatment accordingly. This approach can help reduce mortality and improve patient outcomes, which is also a key focus for hospital medicine teams.
