Alfentanil and the Elimination of Sympathetic Responses to Tracheal Intubation During Rapid Sequence Induction of Anesthesia: A Probability-based Approach
Induction of anesthesia:
After 3 minutes pre-oxygenation with 100% oxygen, a blinded dose alfentanil (0,10,20,30,40,50 or 60 µg/kg, followed by thiopental 4 mg/kg and rocuronium 0.6 mg/kg will be administered over 15 sec. Laryngoscopy will be performed 40 s. after injection of rocuronium, with the goal being to have the endotracheal tube passed through the patients vocal cords and the cuff inflated within the following 15 s . The investigator performing the tracheal intubation is blinded to the dose of alfentanil administered.
As part of the study efficacy, blood samples, will be collected prior to induction and 30 s., 1 min. 3 min. and 5 min postintubation to determine blood concentrations of alfentanil and catecholamines.
