This is completely normal of course. Whilst some patients have concerns about the actual surgery, others just worry about the anaesthetic side of things only.
Rest assured, Mr Banwell uses only the very best Consultant Anaesthetists in his practice and he would be happy for any them to put himself or indeed a member of his family to sleep.
Modern anaesthetic agents mean a quicker recovery and less nausea and vomiting that was once common-place after an operation. This allows patients to get up and about much quicker and with regular analgesia recovery can be swift. Day case surgery is also a real possibility using TIVA or similar methods. Ask Mr Banwell for more information.
The hospital where your procedure takes place will pre-assess you and, if necessary, you can see the anaesthetist beforehand to help allay any fears.
