Changes in Respiratory System Resistance As a Percentage of the Thiopental Baseline Recorded after Tracheal Intubation but Before the Addition of Sevoflurane or Desflurane to the Inhaled Gases or Beginning the Infusion of Thiopental Airway Resistance Responses to Sevoflurane Were Significantly Different from Desflurane and Thiopental. *p <0.05

Changes in respiratory system resistance as a percentage of the thiopental baseline recorded after tracheal intubation but before the addition of sevoflurane or desflurane to the inhaled gases or beginning the infusion of thiopental. Airway resistance responses to sevoflurane were significantly different from desflurane and thiopental. *P <0.05
