Statement on Entonox and Fitness to Drive
Tuesday, 06 July 2010 09:01
The BSGE has recently received an enquiry into the use of Entonox and fitness to drive. Entonox (50% nitrous oxide, 50% oxygen, manufactured by BOC) is mainly used in obstetric units and by the ambulance service, but its analgesic and sedative properties with rapid onset and offset make it a potentially attractive agent in patients having colonoscopy and it is already in use in many units. A number of publications in the 1990s showed that it is safe and effective, with reduced discomfort and nausea compared to IV agents and allows earlier discharge from the recovery unit. It is perhaps surprising that it is not more widely used.
As for the question of fitness to drive: the recently revised product licence states that patients are fit to drive a vehicle (or operate machinery) after only 30 minutes. Used in combination with a rapidly acting bowel cleansing agent, this could mean that for patients whose colonoscopy is to be done mid-week, only half a day away from work is required – a major advantage for the self-employed. A pdf file, "Entonox: Information for the User" is available from BOC (and on the BSG website)

Urgent Message to all Nurse Endoscopists
Friday, 22 January 2010 10:20
The issue of administering controlled drugs during colonoscopy by nurse endoscopists has recently been highlighted by the RCN. An investigation into the practice of obtaining a medical signature after administration of a controlled drug is currently under review and will result in disciplinary action. This is an illegal act and will therefore be dealt with accordingly. All nurse endoscopists must obtain a documented prescription prior to administering a controlled drug at any time during a colonoscopy procedure.
