Hallucinations after hypospadias repair.

The authors report a case of a 4-year-old child who developed hallucinations after hypospadias repair. He was brought to the emergency department the morning after outpatient surgery where the diagnosis of central anticholinergic syndrome was made. We review oxybutynin overdose and the importance of providing clear instruction to parents and caregivers about the administration of medications.

A comparison of airway responses during desflurane and sevoflurane administration via a laryngeal mask airway for maintenance of anesthesia.

Although sevoflurane is less pungent than desflurane at larger concentrations, neither anesthetic seems to irritate the airway when administered at the smaller concentrations often used during maintenance of anesthesia. Both anesthetics may be delivered effectively via a laryngeal mask airway, with minimal evidence of airway irritation.

Using the laryngeal mask airway to manage the difficult airway.

Before 1990, the choice of an airway device essentially was limited to the facemask or the endotracheal tube. Since then, a number of novel supraglottic airway devices have been developed. The laryngeal mask airway (LMA) was introduced to the United States in 1991 after 3 years of use in the United Kingdom and other countries.
