Table 1. Preoperative Respiratory Evaluation and Intraoperative Hemodynamic and Pulmonary Data for the Lidocaine and Albuterol Study Phases

Pulmonary resistances (R^L), performed after intubation, are presented for pre- and postisoflurane measurements. For preisoflurane measurements, data include the initial R^Land the greater of the two measurements obtained before isoflurane (max R^L). Values are presented as mean (SD) or number (% of total). For lower pulmonary resistance, the median range are presented below.

P < 0.01 compared with preisoflurane data.

FEV¹= fractional expiratory volume in 1s; HR = heart rate; MBP = mean blood pressure; postintubation R^L= measured airway resistance (R^L) immediately after intubation and before administration of isoflurane (Forane); Postisoflurane R^L= measured airway resistance after administration of isoflurane.
