Table 2. Incidence of Responses to Tracheal Intubation According to Primary and Secondary Definitions of a Response

Data are presented as number of responders in each subgroup (percentage of group) for each definition of a responder. Airway resistance (RL) is recorded in l · cm H2O−1· s−1. Preisoflurane resistance (RL) refers to the greater of two measurements performed after intubation and before administration of isoflurane. A decrease in RLrefers to a ≥ 50% decrease in RLmeasurements obtained after administration of isoflurane. The secondary definitions were created to account for those patients who may have had increased RLbefore and  after isoflurane because it was possible for a patient to have bronchoconstriction that did not resolve during the study period. The data were also evaluated with an RLof 3 l · cm H2O−1· s−1considered as increased.
