"I was delighted to take part in a clinical trial as it has the potential to really help others in the future.”
A trial to find the best way of controlling pain during and after pleurodesis (TIME1 Trial)
Pleurodesis means sealing the space between the 2 outer linings of the lungs (the pleura) so that fluid can’t collect there. This fluid build up is called a pleural effusion and it can cause shortness of breath.
More about this trial
Doctors can treat pleural effusions by draining off the fluid through a tube, called a chest tube. They may also put talc through the chest tube to seal up the space around the lung and stop the fluid coming back again. But this can cause pain and discomfort. The researchers in this trial wanted to find the best way of controlling this pain.
Doctors can use a large or small size chest tube for the pleurodesis. And they usually give people painkillers when they have this procedure. They sometimes use an opioid painkiller called Oramorph (morphine), or a non steroid anti inflammatory drug (NSAID) called ibuprofen. In this trial, some people had morphine and some people had ibuprofen for pain.
The aims of this trial were to find out
- The best way of controlling pain during and after pleurodesis
- Whether size of chest tube or type of painkillers affect how well pleurodesis works
Summary of results
The trial team found that there was no difference in pain scores between the 2 different types of painkillers. Having a small chest tube resulted in less pain and discomfort but the fluid build up was more likely to come back in this group.
320 people took part in this trial.
206 people had a large chest tube put in. This is because their doctor needed to have a look at the lining of their lung with a small camera. This is called a
They were then put into 1 of 2 treatment groups at random
- 103 had the morphine
- 103 had the ibuprofen
114 people didn’t need a thoroscopy and were put into 1 of 4 treatment groups at random
- 28 had a large tube and morphine
- 29 had a large chest tube and ibuprofen
- 29 had a small chest tube and morphine
- 28 had a small chest tube and ibuprofen
Everyone completed a pain questionnaire after the pleurodesis at
- 1 week
- 1 month
- 3 months
- 6 months
People also had a chest x-ray or ultrasound scan 1 month and 3 months after the pleurodesis.
When the trial team looked at the results, they found
- No difference in pain scores between the 2 types of painkillers. But people who had ibuprofen needed pain relief more frequently.
- People who had smaller chest tubes reported less pain but the fluid build up was more likely to come back at 3 months
The trial team concluded that there was no difference in pain scores. Having a smaller chest tube was a bit less painful but wasn’t as successful as the larger tube to stop the fluid building up again.
