Day Zero


You will be admitted to hospital on the morning of surgery unless you have specific medical problems that your anaesthetist and surgeon wish to monitor closely overnight. It is understood that you will have had a thorough shower prior to admission, and that you bring along everything you require for your hospital stay. If you have any further questions for your surgeon or anaesthetist, please write them down and bring them with you to hospital.

CPAP (continuous positive airway pressure)

If you currently use CPAP for obstructive sleep apnoea, please bring your machine with you to hospital.


Bring in all medications, including over the counter and herbal medications. Don’t stop any medications unless told to do so by your anaesthetist or surgeon.

During the admission process your surgeon, anaesthetist, admission nurse and theatre nurse will see you. This will mean that different people ask you the same questions. This is a safety issue, and although it can be frustrating, it is important. Use this time to ask any questions that you may have.

When you have been admitted and changed into your theatre gown and TEDs (stockings to prevent leg clots), you will wait in the preoperative area until theatre is ready. A warming blanket is often used at this time to keep you extra warm. A final check between the theatre staff and the admission staff takes place before you go through to the theatre.

You will move onto the theatre bed, which is narrow and firm, and a blood pressure cuff, ECG and an oxygen monitor will be attached to you so your anaesthetic team can monitor you closely throughout the procedure. Your anaesthetist will place a drip into a vein and ask you to breathe some oxygen through a plastic facemask. Your anaesthetist will then gently send you off to sleep.
