A recently developed endotracheal tube with a movable bronchial blocker (Univent tube) was used for single lung ventilation. A total of 50 intubations were undertaken for a wide variety of thoracic procedures. Each case was analyzed with respect to ease or difficulty of intubation, tube dislodgment, efficacy of lung collapse, and adequacy of single lung ventilation. Successful, safe selective intubation was accomplished in all cases.

Comparative StudyA comparison of labetalol, acebutolol, and lidocaine for controlling the cardiovascular responses to endotracheal intubation for oral surgical procedures.
Arterial blood pressure and pulse rate changes following tracheal intubation were studied in 80 patients undergoing oral surgical procedures who received an etomidate/suxamethonium anesthetic induction sequence. Three treatment groups and a control group were used. ⋯ A pre-induction dose of labetalol was found to be more effective than acebutolol and lidocaine in attenuating the pressor response to instrumentation and intubation. Labetalol should prove most useful for those patients at risk from the transient hypertension and tachycardia following instrumentation and intubation.

End-tidal PCO2 measurements sampled at the distal and proximal ends of the endotracheal tube in infants and children.
To determine whether the site of gas sampling affects end-tidal gas measurements in pediatric patients, end-tidal PCO2 was measured continuously from the distal and proximal ends of the endotracheal tube in 60 infants and children ventilated with an Air-Shields Ventimeter and a partial rebreathing circuit. These data were compared with simultaneous arterial PCO2 measurements. ⋯ In infants and children weighing less than 12 kg, however, only distal end-tidal PCO2 measurements approximated arterial PCO2 measurements. It is concluded that in infants and children weighing less than 12 kg, accurate end-tidal measurements can be obtained only from the distal end of the endotracheal tube.
