The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Read our disclaimer for details.

Thomas Mencke, University of Rostock
  Purpose
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.

Condition Intervention
Vocal Cord; Injury, Superficial Drug: Sevoflurane Drug: propofol

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Triple (Participant, Investigator, Outcomes Assessor)
Primary Purpose: Prevention
Official Title: Laryngeal Injuries After Removal of the Tracheal Tube: A Comparison Between Anesthesia With Sevoflurane and Intravenous Anesthesia With Propofol A Randomized, Prospective, Controlled Trial

Arms Assigned Interventions
Active Comparator: Sevoflurane
Anesthesia was maintained with sevoflurane during surgery.
Drug: Sevoflurane
Maintenance of anesthesia with sevoflurane 1.0 Vol%
Other Name: remifentanil
Active Comparator: Anesthesia with propofol
Anesthesia was maintained with propofol during surgery.
Drug: propofol
Maintenance of anesthesia with propofol
Other Name: remifentanil

Detailed Description:
Volatile anaesthetics increase neuromuscular block of neuromuscular blocking drugs. We tested the hypothesis, that sevoflurane would cause less vocal cord injuries than an intravenous anaesthesia with propofol. Sixty five patients were randomly assigned to the SEVO group (anaesthesia with sevoflurane) or TIVA group (anaesthesia with propofol). Vocal cord injuries were examined by stroboscopy before and 24 and 72 h after surgery; hoarseness was assessed up to 72 h.
