Opioids are the main stay of analgesia in cardiac surgery because of the safer hemodynamic profile and sedation. However high dose narcotic use is associated with a variety of unwanted side effects prolonging postoperative recovery. There is growing evidence for the effectiveness of multimodal approach utilizing opiate sparing techniques for enhancing patient recovery following surgery. Early extubation has been associated with improved patient outcome and cost effectiveness in cardiac surgery. The investigators objective is to assess the effectiveness of an opioid sparing multimodal approach for enhancing the recovery in Cardiac Surgical patients. This model would use a combination of intravenous (Dexmedetomidine, Ketamine, Lidocaine) and Spinal (Morphine) drugs. All of the above anesthetic drugs have opioid sparing effect in surgical Patients.
