Airway Responses During Desflurane Anesthesia Via a Laryngeal Mask Airway: Effects of Fentanyl Pretreatment

Summary

The investigators plan to test the hypothesis that pretreatment with fentanyl prior to induction of anesthesia would result in reduce the incidence of movements and airway responses to desflurane in patients breathing spontaneously through a laryngeal mask airway (LMA). The primary aim of this study is to assess the effect of fentanyl pretreatment on the incidence of movement during induction of anesthesia. Secondary aim of the study is to evaluate the effects of titration of fentanyl according to the respiratory rate on the incidence of intraoperative respiratory events such as coughing, breath holding and laryngospasm.
