Dexmedetomidine (DEX) is an alpha-2 receptor agonist with sedative and analgesic properties. It has been reported to preserve the patient's ability to cooperate and provide opioid sparing properties. Patients with obstructive sleep apnea (OSA) have demonstrated an increased risk for oxygen desaturation following general anesthesia. We report a case of a 64-year-old male, ASA IV with severe chronic obstructive pulmonary disease, OSA, unilateral vocal cord dysfunction, gastro-esophageal reflux disease, and congestive heart failure undergoing an awake thyroidectomy under local anesthesia and a DEX infusion. The patient was given a loading dose of DEX of 1 mcg/kg and an infusion ranging from 0.2 to 1.0 g/kg/hr. He received a total of 250 mcg of fentanyl and 7.5 mg of ketorolac throughout the case. ⋯ This case demonstrates the successful use of a DEX infusion along with local anesthesia administered by the surgeon for an awake thyroidectomy.
