Use of vecuronium and labetalol in patients with phaeochromocytoma

The safety of a rapid sequence induction for patients at risk from a full stomach relies to some extent on ensuring the minimum time of exposure of the airways to the potential hazard of gastric regurgitation or vomiting. Any manoeuvre that may shorten this time of exposure would seem worth while. A simple technique is described which enables a few seconds to be clipped off the time to complete intubation. The pilot tube is connected via a three-way tap and infusion sebto an evacuated SO-ml infusion bag which contains a predetermined volume of air, suitable for adequate cuff inflation, previously introduced through the tap using a calibrated syringe. The infusion bag is placed on the floor next to the operator’s foot. Once the tracheal tube has passed the cords the cuff is instantly inflated when the bag is compressed by the anaesthetist’s foot. The procedure avoids the delay in fumbling for the inflation syringe while removing the laryngoscope and also prevents the assistant from releasing cricoid pressure during an attempt to help to steady the swinging syringe! Appropriate re-adjustment of the cuff pressure may then be undertaken in the normal manner. The use of an in-line cuff pressure monitor may also be helpful.
