Main operating theatres


This information is for patients who are having an operation in our main operating theatres.

Before your surgery

Your surgery will have been discussed with you at your appointment before your surgery (pre-operative assessment).

What can I expect?

When the team is ready to begin your surgery, you will be brought down to the operating theatres. Depending on where you have been admitted, this may be from the:

You will be taken into the anaesthetic room where the anaesthetist and anaesthetic assistant will give you your anaesthetic. The length of time this takes and type of anaesthetic you will have will depend on the procedure. This will have already been discussed with you. 

You will then be taken into the operating theatre for your operation. 

Please note that only relatives of children having surgery and overnight intensive recovery patients will be allowed into the main theatre areas. No other visitors are allowed to enter these areas.

After your surgery

You will be taken to the recovery area and once you have recovered from your anaesthetic you will be transferred to a ward or to day surgery to be discharged home, depending on the surgery you have had.

Patients who have had complex surgery, such as heart surgery, may stay overnight in intensive recovery.
