Most patients have either a silicon or plastic airway tube inserted in their throat during an operation. This is inserted to ensure easy breathing and/or to protect the lungs from the stomach fluids and acid during the anaesthetic and operation. Although these tubes are soft and lubricated, they do tend to rub the throat. The effect on your voice or your throat may last a few hours - the longer the operation, the longer the effect. You may become aware of this airway tube just as you are waking up. It will be removed as soon as it is safe to do so ' usually a matter of moments.
