Nausea is not an uncommon side effect occurring in 10-20% of children. This is usually short lived and medication will be given to reduce it.
Minor discomfort is another side effect that can occur. Every effort is made to prevent this. Usually the combination of paracetamol before the operation, and local anaesthetic injected during the operation to numb the area works very well. If required, strong pain relief will be given through the drip.
If you have any specific questions that you would like answered prior to the planned day of surgery please do not hesitate to call.
