Comparison of Two Induction Regimens Using Topical Lidocaine or Muscle Relaxant on Sore Throat and Hemodynamics

When a surgical procedure is performed under general anesthesia, the Airways are often secured With an endotracheal tube. Some patients experience sore throat thereafter. Studies have shown a reduction of these side effects when by use of muscle relaxants or a lidocain spray prior to the intubation. At Ostfold Hospital Trust, the investigators use one of the two methods or nothing. These methods will be studied systematically. Heart rate and blood pressure rise during the intubation procedure. The investigators will also study the differences between the groups.
