PY - 2021 T2 - Decision Making in Perioperative Medicine: Clinical Pearls AB - Adrenal function is critical to stability in the surgical milieu in order to maintain hemodynamic stability and end organ perfusion.1,2 The stress of surgery, trauma, and critical illness, and the vasodilation associated with anesthesia, in conjunction with blood loss and fluid shifts, can lead to hypotension and shock in the setting of inadequate adrenal reserves. There are two distinct populations of relevance in this regard: patients with established and confirmed primary or secondary adrenal insufficiency (from cortisol or ACTH deficiency, respectively), and patients with suspected tertiary adrenal insufficiency related to use of exogenous glucocorticoid therapy that suppresses the hypothalamic-pituitary-adrenal (HPA) axis and ACTH release from the hypothalamus.
