It is common to use muscle relaxants, such as succinyl choline to produce muscle relaxation during tracheal intubation.

Based on some new researches alfentanyl was reported to be used without succinyl choline for tracheal intubation. The goal of this study was to evaluate the quality of tracheal intubation during general anesthesia with alfentanyl in order to see whether it can be used as a substitution for succinyle choline when this drug is contraindicated or not available. For this purpose 132 patients in ASA I & /I physical condition were divided randomly into case and control groups for evaluation of the quality of intubation. In control group sodium thiopenthal 5 mg/kg and succinyle choline 1.5 mg/kg, while in case group sodium thiopenthal 5 mg/kg as well as alfentanyl 20 flg/kg were used Intravenously. The results were assesd by using chi-square formula.

Laryngoscopic qualification such as mandibular (Jaw) relaxation, coughing condition, limb movement and ease of laryngoscopy showed no difference between the two groups (P>0.05). The only differing parameter was the position of vocal cords (P<0.0018) which was more acceptable in control group using, succinly choline.
