During the procedure

You will be offered pain relief for this procedure, there are two options available:

Conscious Sedation and Analgesia – Sedation is given via a cannula and helps to relax you but it does not put you to sleep. It is usually given together with a painkilling medication. You will still be able to hear and talk with the staff and follow instructions. After the procedure you will be taken to the recovery area to rest and you will be given refreshments. If you have sedation you must have a responsible adult to collect you from the Endoscopy Unit to take you home and stay with you for 24 hours as the medication can stay in your system during this 24 hour period. You cannot drive, operate machinery (including household appliances) or sign legal documents during this 24 hour period. You are advised not to travel home on public transport.

Entonox – Entonox is a medical gas; it is a mixture of 50% Oxygen and 50% Nitrous Oxide. Entonox is used for pain relief during childbirth, acute trauma such as broken bones and other medical procedures and it is very effective for pain relief during flexible sigmoidoscopy.
