5. Study Description
Brief Summary
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.
Detailed Description
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.
