Y1 - 2021 N1 - T2 - Decision Making in Perioperative Medicine: Clinical Pearls AB - Thyroid dysfunction is ubiquitous in the general population, with approximately 4–21% of females and 3–16% of males having abnormal thyrotropin (thyroid-stimulating hormone or TSH) values.1 Thyroid hormones affect several systemic functions that impact the perioperative period. While routine testing of thyroid parameters in patients with known stable disease is not necessary, clinical assessment of patients with known or suspected thyroid dysfunction and optimization of these conditions are essential to mitigating adverse perioperative outcomes. In addition, both subclinical and overt hyperthyroidism and hypothyroidism are present in millions of patients, so a higher index of suspicion is warranted to recognize these subclinical variants and determine if management changes in the perioperative period are warranted.
