Adrenal Crisis; Roadside to Resus

Adrenal crisis represents a life-threatening medical emergency requiring immediate recognition and intervention, particularly in patients with undiagnosed adrenal insufficiency. This condition exists on a clinical spectrum where symptoms like unexplained hyperpigmentation, persistent nausea, and postural hypotension serve as critical diagnostic clues. Pathophysiological failure often stems from HPA axis suppression due to long-term exogenous steroid use, rendering the body unable to mount a necessary stress response. Effective management mandates the early administration of 100mg hydrocortisone and aggressive fluid resuscitation, as these interventions can reverse cardiovascular collapse within hours. Because adrenal crisis is relatively rare and often mimics common conditions like sepsis, maintaining a high index of suspicion and utilizing patient-held steroid emergency cards are essential strategies for improving outcomes and preventing mortality in this vulnerable patient cohort.
