High Thoracic Epidural Anesthesia and Dexmedetomidine for Awake Off-Pump Coronary Artery Bypass Grafting: A Feasible Option for Patients with Severe Pulmonary Disease

High thoracic epidural anesthesia in cardiac surgery as the sole anesthetic technique is used in a select groups of patients having severe pulmonary co morbidities. We describe a case series of three patients at high risk for post operative pulmonary complications where this technique was used along with dexmedetomidine infusion for conscious sedation in off pump coronary artery bypass grafting. Proper selection of patients, proper placement of the epidural catheter at the appropriate level and timing of catheter insertion and removal are of paramount importance.
