E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
Verify if long term (14 days) local anesthetics infusion into the wound has a greater analgesic efficacy then placebo, assessed as reduction of opioid consumption and reduction of Numeric Rate Scale (NRS). |
Verificare se l’infusione di anestetico locale a livello dell’incisione chirurgica abbia una maggiore efficacia analgesica del placebo nei primi 14 giorni dopo l’intervento, valutata tramite riduzione del consumo di farmaci analgesici (dose media di farmaco analgesico, associazione tramadolo+paracetamolo, necessaria per mantenere NRS<4 nei 14 giorni successivi all’intervento). |
|
E.2.2 | Secondary objectives of the trial |
Verifiy if the active treatment is able to determine:
- Reduction of persistent pain (PMPS) incidence;
- Reduction of side effects;
- Reduction of surgical complication incidence;
- Better functional recovery;
- Quality of life improvement and early return to social life; |
Dimostrazione nel gruppo di pazienti riceventi infusione di anestetico locale di:
- Riduzione del dolore nei 14 giorni seguenti l’intervento chirurgico;
- Riduzione dell’incidenza di effetti collaterali;
- Riduzione dell’incidenza di complicanze chirurgiche (infezione della ferita, deiscenza dei lembi, linfedema omolaterale dell’arto superiore, ecc);
- Migliore recupero funzionale dell’arto superiore;
- Miglioramento della qualità di vita e ripresa precoce delle attività socio-affettive;
- Riduzione dell’incidenza di dolore persistente. |
