Laryngeal Injuries After Anesthesia Induction With Sevoflurane and After Anesthesia Induction With Rocuronium

Laryngeal Injuries After Anesthesia Induction With Sevoflurane and After Anesthesia Induction With Rocuronium. A Randomized, Prospective, Controlled Trial

Anesthesia induction with sevoflurane is not associated with an increased incidence or severity of laryngeal injuries compared with an anesthesia induction with a muscle relaxant.

Inclusion Criteria:

• ear-nose-throat surgery
• orotracheal intubation for surgery of the ear

Exclusion Criteria:

• obesity
• allergy against the study drugs
• patients with a known or suspected difficult airway (Mallampati score 3 or 4 and a mouth opening < 3.5 cm).
• all patients were examined by stroboscopy one day before surgery and were excluded from the study when preexisting pathologies of the vocal cords were found
