Lidocaine is a local anesthetic which is widely used in daily anesthesia and surgical practice. It has been shown that intravenous lidocaine given during an operation has analgesic properties. Finally intravenous lidocaine is inexpensive and easy to administer and safe if non-toxic doses are respected. It is likely that the use of lidocaine infusions during anesthesia might increase in the coming years. Neuromuscular blockers (curare like substances) are used in anesthesia to facilitate tracheal intubation and to achieve muscle relaxation and immobility during surgery. Rocuronium is one of the most widely used neuromuscular blocking agents. Local anesthetics, such as lidocaine, are known to potentiate the effect of neuromuscular blocking agents. In the study the investigators want to evaluate the effect of intravenous lidocaine during the operation on the time course of the rocuronium-induced neuromuscular block. A secondary aim is to evaluate intubation conditions (lidocaine has been shown also to improve intubation conditions) and safety.

Primary Outcome Measures:
  • Onset and recovery of the neuromuscular block [ Time Frame: From start of injection of rocuronium until TOF 90% ]

Secondary Outcome Measures:
  • To evaluate intubation conditions at T1, we will use the scale according to the Good Clinical Research practice (GRCP) in neuromuscular research [ Time Frame: 2 to 3 minutes ]
  • Any minor adverse event (no need for intervention) or major adverse event will be recorded. [ Time Frame: up to 5 hours ]

Enrollment: 52
Study Start Date: August 2009
Study Completion Date: August 2010
Primary Completion Date: August 2010 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Placebo Comparator: Placebo Drug: Placebo
Immediately before induction, patients will receive 0.15 ml kg-1 of the study drug as an intravenous bolus followed, after tracheal intubation, by a continuous intravenous infusion of 0.2 ml kg-1 h-1. In the Placebo group this will be physiologic saline. The infusion will be stopped after complete recovery from the neuromuscular block.
Active Comparator: Lidocaine Drug: Lidocaine
Immediately before induction, patients will receive 0.15 ml kg-1 of the study drug as an intravenous bolus followed, after tracheal intubation, by a continuous intravenous infusion of 0.2 ml kg-1 h-1. In the lidocaine Arm this regimen corresponds to 1.5 mg kg-1 lidocaine bolus injection and 2 mg kg-1 h-1 lidocaine continuous infusion. The infusion will be stopped after complete recovery from the neuromuscular block.
