Laryngeal Injuries After Removal of the Tracheal Tube: A Comparison Between Sevoflurane and Propofol

• Status: Completed
• Trial end date: 2011-10-01
• Target enrollment: 0
• Participant gender: All

Summary

Vocal cord injuries occur not only during tracheal intubation, but also during surgery and during removal of tracheal tube. Volatile anesthetics increase neuromuscular block of muscle relaxants. Thus, the investigators tested the hypothesis, that sevoflurane would cause less vocal cord injuries than a total intravenous anesthesia with propofol.
