This study is to see if having carbohydrate drinks after surgery to remove part or all of your lung can help your recovery afterwards.

More about this trial

Lung surgery to remove cancer is a major operation that can have serious complications. 

We know from research that having carbohydrate Open a glossary item and protein drinks before and after surgery can help people recover after other types of major surgery.

Researchers want to find out if these drinks might be able to help people recover from major lung surgery. So they want to do a clinical trial Open a glossary item with a large number of people. In this trial they will compare people who had carbohydrate drinks before and after surgery with people who didn’t.

Before doing this the researchers need to find out if it is possible to do such a trial. So they’ll ask a small number of people to take part in a feasibility study.

In this feasibility study some of the people will have carbohydrate drinks before and after lung surgery. And some will have water before and after surgery.

Trial design

This is a feasibility study. The study team need 60 people from the Heart of England Foundation Trust to join.  

This is a randomised study. Everyone taking part is put into 1 of 2 groups by a computer. Neither you or your doctor can choose which group you are in. 

You will be in a group having 1 of the following:

  • a carbohydrate drink
  • water

TIC TOC diagram

You have the carbohydrate drink or water:

  • 4 times the evening before your operation
  • at least twice on the day of surgery- you’ll have additional drinks if your surgery is in the afternoon
  • twice a day for 2 weeks after surgery

Quality of life
You are asked to fill in a few questionnaires before surgery and then at the following times after your operation:

  • 1 day
  • 2 days
  • 3 days
  • the day you leave hospital
  • 3 to 4 weeks
  • 3 months (this can be done by post or telephone)

The questions ask about how you are feeling, any pain or other symptoms you have had after surgery. This is called a quality of life questionnaire

The study team will telephone you 3 to 4 weeks after surgery to ask about your:

  • surgery and recovery
  • feelings and thoughts about taking part in the study

Hospital visits

You see the doctor before surgery to talk about your operation and to have a couple of tests done. These tests measure:

  • how strong your grip is (hand grip strength)
  • how much air you breathe out (peak flow)

You have these tests done again after your surgery at:

  • 1 day
  • 2 days
  • 3 days
  • the day you leave hospital

You see the doctor 3 to 4 weeks after leaving hospital to see how you are and to have the hand grip and peak flow tests (if needed).

Side effects

The carbohydrate drinks you have before surgery have a light lemon taste that some people may not like. 

The drinks after surgery comes in different flavours and you can choose which flavour you have.
