Other Specified Injuries of Vocal Cord, Sequela Clinical Trial
Official title:
Laryngeal Injuries After Anesthesia Induction With Three Different Sevoflurane Concentrations (Without Muscle Relaxant)
Anesthesia induction and tracheal intubation can be performed with and without neuromuscular blocking agents (NMBAs). Tracheal intubation can be performed with sevoflurane instead of NMBAs; intubating conditions are similar and the incidence of vocal cord injuries are similar, too.
We perform tracheal intubation with propofol, remifentanil and sevoflurane; sevoflurane is administered with three dosages. During tracheal intubation intubating conditions are noted. After surgery, all patients are examined by video laryngoscopy; moreover all patients are asked for hoarseness and sore throat. ;
Allocation: Randomized, Endpoint Classification: Pharmacodynamics Study, Intervention Model: Parallel Assignment, Masking: Double Blind (Subject, Investigator, Outcomes Assessor), Primary Purpose: Prevention
