ALLEGRO is a research study investigating if Intravenous (IV) Lidocaine improves recovery of gut function after colorectal surgery for NHS patients.
A common problem in about 40% of patients having colorectal (large bowel) surgery is that their gut takes longer than normal to start working again. In most patients the gut will start working after surgery in 2-3 days, but in some it takes a week or more. This delayed recovery causes nausea, vomiting, complete constipation, tummy pain and tummy swelling and can take days to improve. During this time patients have to stay in hospital with a continuous intravenous drip and often need insertion of a nasogastric tube to empty the stomach to reduce vomiting (most patients find this very unpleasant).
Lidocaine (a local anesthetic) used intravenously (through the vein) has been shown to reduce pain and inflammation after surgery and seems to help other aspects of recovery that may be important for return of gut function, for example reducing nausea and vomiting.
We are recruiting patients at hospitals in the UK. You may be eligible to take part in ALLEGRO if:
• You are aged 18 or over,
• You are scheduled for colorectal resection at participating surgery units
• You have no contraindications to Lidocaine.
If the hospital you have been referred to for your colorectal surgery is participating in ALLEGRO, your surgeon may discuss the study with you at your hospital visit.
If you would like any more information about ALLEGRO, including information about taking part, please contact the study office at the University of Edinburgh on 0131 ###### or use the contact us form found below.
If you are eligible and would like to take part in the ALLEGRO study you will be recruited at your local hospital (please see the section ‘Where can I take part? to check if your local hospital is participating).
If you want to take part we will ask you to sign a consent form and answer some questions about your health. We will also ask you to complete a study questionnaire.
After this we will randomize you to receive either
• Intravenous Lidocaine during your operation or
• Intravenous placebo (dummy) during your operation.
Throughout your stay in hospital we will ask you questions about any pain or. Nausea, your ability to eat and drink and other aspects of your recovery. Following discharge we will contact you by telephone 30 days and 90 days after your surgery and ask you some questions about your recovery.
ALLEGRO has been funded by the National Institute for Health Research. For more information please visit www.nets.nihr.ac.uk.
