Summary

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.

Conditions

  • Neuromuscular Block

Interventions

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.

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.
