Brief summary
This observational study evaluates difference in chronic pain after six months from surgery between patients who received PECS block and general anesthesia versus general anesthesia alone.
Detailed description
PECS block is used as a pain relief technique during breast surgery. However at the actual state of knowledge there is no strong evidence that its use could lower incidence of chronic pain compared to general anesthesia alone. Moreover for its use an adequate skill with ultrasound machine is required. For this reason only some anesthesiologists in our reality use this technique it in clinical practice.
Interventions
PROCEDUREPECS block
It consists in injection of 20-30 ml of local anesthetic between pectoral minor, pectoral major, and serratus muscles.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Chronic pain at six months | six months | Presence of chronic pain at six months after surgery. For this purpose patient will be asked to report presence of pain on breast, neck, axilla or arm. If patient will report pain a further question about intensity (NRS) and quality (we will ask to patient to describe with words from one to three the pain). Furthermore we will ask to patient if he had take any action (eg drugs) to treat pain |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Chronic pain at three months | three months | Presence of chronic pain at three months after surgery. For this purpose patient will be asked to report presence of pain on breast, neck, axilla or arm. If patient will report pain a further question about intensity (NRS) and quality (we will ask to patient to describe with words from one to three the pain). Furthermore we will ask to patient if he had take any action (eg drugs) to treat pain |
| Chronic pain at nine months | nine months | Presence of chronic pain at nine months after surgery. For this purpose patient will be asked to report presence of pain on breast, neck, axilla or arm. If patient will report pain a further question about intensity (NRS) and quality (we will ask to patient to describe with words from one to three the pain). Furthermore we will ask to patient if he had take any action (eg drugs) to treat pain |
| Chronic pain at twelve months | twelve months | Presence of chronic pain at twelve months after surgery. For this purpose patient will be asked to report presence of pain on breast, neck, axilla or arm. If patient will report pain a further question about intensity (NRS) and quality (we will ask to patient to describe with words from one to three the pain). Furthermore we will ask to patient if he had take any action (eg drugs) to treat pain |
| Difference in opioid consumption during surgery | day of surgery | Difference in opioid consumption during surgery (Fentanyl as mcg/kg/h; Remifentanil as mcg/kg/min) |
| Difference in pain in the first 24 hours after surgery | first 24 hours after surgery | maximum and mean NRS score in the first 24 hours after surgery |
