Lidocaine as an Endotracheal Tube (ETT) Cuff Media

At the time of intubation, the endotracheal tube cuff will be inflated with a solution containing 1.8% lidocaine plus 0.76% sodium bicarbonate until loss of air leak at a positive pressure of 20 cm of water. This solution will remain in situ through the duration of cardiac surgery, transportation to the intensive care unit, and continued to the time of extubation.
