Oral bowel preparation agents

7th September 2012 by Louise Hudman

You may have seen the recent letter from QA asking that we prescribe bowel prep for patients going to endoscopy. This guideline gives advice on how you can safely do this.

Portsmouth prefers Picolax (contains sodium picosulphate and magnesium citrate) and Klean Prep (contains polyethylene glycol). Generally Picolax is used if possible as patients tend to prefer it. I will therefore summarise some of the issues with these two products and some other things to be aware of – but this is by no means exhaustive!

Picolax. Ideally use only if GFR is > 60. It can be used if GFR is lower, but only if Klean Prep isn’t tolerated. Be very cautious if they are CKD 4 or 5. Use with caution if the patient is at risk of hypovolaemia (as below). Avoid if they have liver failure or cirrhosis.

"LocumDeck does everything you want it to do in an instant and with audit trails.

I absolutely love the facility for receiving Locum's invoices and the facility for signing the Pension Forms electronically and they are then instantly sent with an audit trail! It is fabulous!

You are notified the moment a Locum GP adds availability which is just fantastic, I spend a lot of time just chasing agencies to see if they have availability, so to be notified the moment availability is advertised is a new concept and very welcome! I have no hesitation in recommending LocumDeck - it has already eased my workload!"
