Intra operative Nerve Monitoring ( IONM ) is rapidly becoming the standard of care for thyroid surgery to prevent injury to the recurrent laryngeal nerve. However the laryngo tracheal reflexes need to be adequately suppressed to permit proper utilization of intra operative nerve monitoring. Increasing the depth of anesthesia to achieve this often leads to side effects. Intravenous lidocaine infusion has been shown to be effective in blunting these reflexes. The planned study intends to look at the efficacy of intravenous lidocaine infusion in decreasing the amount of anesthesia medications needed to suppress the reflexes. Also the study looks at the analgesic and anti emetic properties of intravenous lidocaine infusion post operatively by measuring these outcomes.
The study is designed as a double blinded randomized controlled trial with 30 subjects in the group who will receive intravenous lidocaine during surgery and 30 subjects in the group who will receive placebo. Blunting of the laryngo tracheal reflexes intra operatively will be recorded as the primary outcome. The amount of anesthesia medications, the post operative patient comfort level, pain control, usage of narcotic pain medications, nausea, vomiting will be recorded as secondary outcomes.

Subjects in the Lidocaine arm of the randomized trial will receive a bolus of 1 mg /Kg of IV lidocaine followed by 1.5 mg/KG/h of IV lidocaine infusion during the surgery which will be stopped at extubation.
Other Name: Xylocaine, Lignocaine
Placebo Comparator: Placebo
Subjects in the Placebo arm of the randomized trial will receive a bolus of 1mg/kg Placebo ( 0.9% saline) followed by 1.5 mg/KG/h Placebo ( 0.9% saline) infusion during the surgery which will be stopped at extubation.
Other Name: Normal Saline
- Suppression of laryngo tracheal reflexes during thyroid surgery [ Time Frame: From beginning of surgery to the end of surgery ]Number of times laryngo tracheal reflexes were encountered during surgery will be recorded.
- Amount of Anesthesia medications used [ Time Frame: From beginning of surgery to the end of surgery ]The total amount of each anesthesia medication used will be recorded
- Post operative pain control [ Time Frame: At 30 minutes, two hours, eight hours, 24 hours after surgery ]Pain will be measured on a scale of 1 to 10
- Post operative usage of medications to control pain [ Time Frame: Within 24 hours of surgery ]The total amount of medications used to control pain will be recorded
- Post operative nausea [ Time Frame: At 30 minutes, two hours, eight hours, 24 hours after surgery ]Number of episodes of nausea and vomiting will be recorded
- Post operative overall patient comfort as measure of the anti inflammatory effect of Lidocaine [ Time Frame: At 30 minutes, two hours, eight hours, 24 hours after surgery ]Comfort level will be measured on a scale of 1 to 10
