“Intra-operative Lidocaine Infusion in Preventing CPSP Post VATs”
The aim of this study is to evaluate the impact of intravenous lidocaine on acute and chronic post surgical pain on patients undergoing video assisted thoracoscopic surgery(VATS). The investigators believe that systemic administration of lidocaine during the perioperative period would be effective in preventing chronic pain post VATS. In addition to chronic pain the investigators believe it will reduce acute postoperative pain as well as each patients total opioid requirement.The investigators believe that this will have a significant impact on the care of patients presenting for VATS.
Drug - Lidocaine
. Perioperatively, when lidocaine is administered as a continuous infusion at clinically relevant doses (1-2 mg/kg/hr) results in plasma concentration below 5Âµg.mL-1. At this plasma level, it is adequate to attenuate sympathetic responses , decrease pain and demonstrate a significant opioid sparing effect.
Drug - Saline
The second group will include those who receive a intraoperative placebo infusion(saline infusion) (Induction bolus dose of 1.5 mg/kg body weight followed by a continous saline infusion 1.5 mg/kg/hr.
