What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
drain ablationProcedure or surgery
drain ablation will be done in Aspiration mode or in non Aspiration mode
| Study group | Role | What they receive |
|---|---|---|
| Drain ablation - Non Aspiration mode | Experimental | Drain ablation will be done in non Aspiration mode Receives: Procedure: drain ablation |
| Drain ablation - Aspiration mode | Other | Drain ablation will be done in Aspiration mode Receives: Procedure: drain ablation |
What is being measured
The primary outcome is the main question the study is designed to answer.
Evaluate the pain felt by the patients at the time of the removal of the drain, using the pain visual analogue scale
pain will be measured using a visual analogic scale from 0 (for no pain) to 10 (fo maximum pain)
Measured: 20 minutes
Secondary outcomes (1)
Presence of haematoma after ablation
Presence or absence of haematoma will be visually checked
Measured: Day 2 post ablation
