Plain English summary of protocol
Background and study aims
Body swelling (a buildup of fluid under the skin) often happens after surgery. The aim of this trial is to investigate the reasons to why it happens. The infusion fluids used in the surgery (e.g. resuscitating fluids), the amount of fluid taken by the patient before the surgery, whether the patient suffers from an inflammatory disease and surgical stress (how the body responds to the surgery) are all possible factors that may influence the amount of swelling that occurs after an operation.
Who can participate?
Adult patients (aged at least 18 years), scheduled for surgery that will last for longer than 30 minutes.
What does the study involve?
Urine samples are taken from the patients before, during and after surgery. A blood sample will also be taken the morning after the operation. Patients will be receive either a crystalloid or a colloid infusion fluid during the surgery and be weighted daily until they leave the hospital. Any complications will be recorded.
What are the possible benefits and risks of participating?
The researchers do not believe that there are any benefits or medical risk involved. There may be pain involved when the blood sample is taken.
Where is the study run from?
Södertälje Hospital, Sweden
