简要总结
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.
详细描述
Cardiac surgery is associated with significant acute pain and a proportion of these patients will develop chronic pain.
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.
Dexmedetomidine use has been associated with decreased cardiac arrhythmias and improved neurological outcome in cardiac surgical patients. Ketamine has been linked with attenuation of postoperative cognitive dysfunction after cardiac surgery. Both intravenous lidocaine and spinal morphine have been shown to reduce opioid consumption in the perioperative period.

研究组 & 干预措施
Unrestricted Fentanyl
Will receive injection of sterile saline (2cc) in lower back area (to minimize participant bias) and unrestricted amount of intraoperative opioids (fentanyl) at the discretion of the Anesthesiologist.
Both groups will receive General Anesthesia with volatile agents and single dose of iv Tylenol intraoperatively. Both groups of patients will be transported to Intensive Care Unit (ICU) on Dexmedetomidine (dose range 0.25 - 0.7 mcg/kg/hr). Dose titration is based on sedation level and hemodynamic goals set by Cardiac Anesthesiologist.
干预措施: Unrestricted Fentanyl (Drug)
Lidocaine, Dexmedetomidine and Ketamine
Will receive pre-operative spinal duramorph (4mcg/kg up to max dose of 300mcg), intra-operative intravenous (iv) infusion of Ketamine (0.4 mg/kg/hr), Lidocaine (20 mcg/kg/min) and Dexmedetomidine (0.25 mcg/kg/hr) started after induction of General Anesthesia and maintained through the Cardiopulmonary Bypass (CPB) towards the end of surgery. At this point all infusions will be turned off except Dexmedetomidine. The total intraoperative fentanyl dose will be limited to <250mcg (or 3mcg/kg) and total midazolam to ≤ 2mg in the study group.
干预措施: Lidocaine (Drug)
Lidocaine, Dexmedetomidine and Ketamine
Will receive pre-operative spinal duramorph (4mcg/kg up to max dose of 300mcg), intra-operative intravenous (iv) infusion of Ketamine (0.4 mg/kg/hr), Lidocaine (20 mcg/kg/min) and Dexmedetomidine (0.25 mcg/kg/hr) started after induction of General Anesthesia and maintained through the Cardiopulmonary Bypass (CPB) towards the end of surgery. At this point all infusions will be turned off except Dexmedetomidine. The total intraoperative fentanyl dose will be limited to <250mcg (or 3mcg/kg) and total midazolam to ≤ 2mg in the study group.
干预措施: Ketamine (Drug)
Lidocaine, Dexmedetomidine and Ketamine
Will receive pre-operative spinal duramorph (4mcg/kg up to max dose of 300mcg), intra-operative intravenous (iv) infusion of Ketamine (0.4 mg/kg/hr), Lidocaine (20 mcg/kg/min) and Dexmedetomidine (0.25 mcg/kg/hr) started after induction of General Anesthesia and maintained through the Cardiopulmonary Bypass (CPB) towards the end of surgery. At this point all infusions will be turned off except Dexmedetomidine. The total intraoperative fentanyl dose will be limited to <250mcg (or 3mcg/kg) and total midazolam to ≤ 2mg in the study group.
干预措施: Precedex (Drug)
Lidocaine, Dexmedetomidine and Ketamine
Will receive pre-operative spinal duramorph (4mcg/kg up to max dose of 300mcg), intra-operative intravenous (iv) infusion of Ketamine (0.4 mg/kg/hr), Lidocaine (20 mcg/kg/min) and Dexmedetomidine (0.25 mcg/kg/hr) started after induction of General Anesthesia and maintained through the Cardiopulmonary Bypass (CPB) towards the end of surgery. At this point all infusions will be turned off except Dexmedetomidine. The total intraoperative fentanyl dose will be limited to <250mcg (or 3mcg/kg) and total midazolam to ≤ 2mg in the study group.
