The most common problems encountered with insertion or tolerance of the LMA are due directly to inadequate depth of anesthesia – regardless of the anesthetic agent in use.
* The incidence of coughing during anesthetic maintenance while using a LMA is minimal and does not differ among the anesthetics commonly used for anesthesia, including propofol.

Data for desflurane and isoflurane are from Ashworth and Smith. Data for sevoflurane are from Tang et al. Both of these references supplied the data for propofol.

McKay RE et al. Anesthesia and Analgesia, Nov. 2006
Study tested whether the use of a more pungent anesthetic (desflurane) would result in a higher rate of coughing, breath holding, laryngospasm or desaturation among patients who smoke.

“Desflurane Anesthesia After Sevoflurane Inhaled Induction Reduces Severity of Emergence Agitation in Children Undergoing Minor Ear-Nose-Throat Surgery Compared with Sevoflurane Induction and Maintenance”
Mayer, et al, Klinikum Ludwigshafen, Germany
Anesthesia & Analgesia, February 2006
To evaluate the influence of desflurane maintenance after sevo induction versus sevo induction and maintenance on emergence agitation in pediatrics undergoing ear, nose, and throat surgery.
Maintenance of anesthesia with desflurane after mask induction with sevoflurane resulted in less severe agitation with faster emergence times.
Although time of PACU stay did not differ significantly, a more rapid immediate recovery from anesthesia could be an additional benefit in a busy operating room.

Emergence and Immediate Recovery Times After Discontinuation of Volatile Anesthetics in the Two Anesthetic Groups
The present study demonstrates that morbidly obese patients anesthetized for more than three hours recover significantly more rapidly after desflurane anesthesia than after sevoflurane anesthesia.
