Major depressive disorder (MDD), antidepressants, and uncontrolled hypertension: A report of intraoperative autonomic dysregulation

Abstract

Objective: Major depressive disorder (MDD) represents the leading cause of mental disability worldwide. While relations between MDD and alterations to the cardiovascular system have been studied before, the autonomic dysfunction caused by the disease and the medical therapies involved during treatment has not been widely reported. Our case aims to prove such linkage exists and is a potent hazard during major operative procedures. Methods: Studies have associated the disorder with a concomitant dysfunction of the autonomic nervous system, predisposing patients to hypertension. We present the case of a patient presenting with an intraoperative hypertensive spike that could be attributed to such a dysregulation of the autonomic system, in the absence of any other possible explanation. Results: The observed intraoperative hypertensive spike was managed pharmacologically, and the patient did not experience any further hemodynamic instability or postoperative complications. Conclusion: Our case tries to highlight a disregarded aspect of perioperative management for patients suffering from MDD.
