Brief summary:
This protocol describes a double-blind, placebo-controlled trial intended to demonstrate the effectiveness of lidocaine at reducing pain associated wiht propofol infusion for short-term deep sedation in children. Patients will be randomized to receive either placebo (saline) or one of two dosing regimens of IV lidocaine prior to initiating propofol infusion. The efficacy of the differing lidocaine doses will be compared to determine the minimum dose required to safely achieve alleviation of pain. We hypothesize that premedicating with lidocaine will significantly decrease pain experienced by pediatric patients receiving propofol for outpatient sedation.

Arms:
arm 1: Saline arm 2: Lidocaine 0.25 mg/kg arm 3: Lidocaine 0.5 mg/kg

Interventions: intervention 1: normal saline intervention 2: lidocaine intervention 3: lidocaine
Intervention descriptions: intervention 1: A blood pressure cuff is placed with its distal-most margin 10 cm proximal to the intravenous catheter insertion site and is inflated to 40 mmHg of pressure greater than the patient's pre-procedure systolic blood pressure. Subjects will receive saline placebo IV (Group A) prior to initiating propofol infusion. Five minutes after administration of the study agent, tourniquet pressure is released and propofol infusion will be immediately initiated. intervention 2: A blood pressure cuff is placed with its distal-most margin 10 cm proximal to the intravenous catheter insertion site and is inflated to 40 mmHg of pressure greater than the patient's pre-procedure systolic blood pressure. Subjects will receive lidocaine 0.25 mg/kg IV (Group B) prior to initiating propofol infusion. Five minutes after administration of the study agent, tourniquet pressure is released and propofol infusion will be immediately initiated. intervention 3: A blood pressure cuff is placed with its distal-most margin 10 cm proximal to the intravenous catheter insertion site and is inflated to 40 mmHg of pressure greater than the patient's pre-procedure systolic blood pressure. Subjects will receive lidocaine 0.5 mg/kg IV (Group C) prior to initiating propofol infusion. Five minutes after administration of the study agent, tourniquet pressure is released and propofol infusion will be immediately initiated.
