Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of this study is to evaluate intubation conditions with the use of atracurium after a fixed three-minute delay

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The recommended dose of a non-depolarizing curare to facilitate tracheal intubation is twice the active dose 95 (the dose that reduces muscle force by 95%). At this dosage, curarization of the laryngeal adductors allowing relaxation and abduction (opening) of the vocal cords is considered certain. With atracurium, the dose for intubation is 0.5 mg.kg-1 and the time to full effect is approximately 3 minutes. With the use of newer hypnotics, there are no data evaluating the conditions for intubation after a fixed time of 3 minutes as with current anesthetic practices.
