Summary
Brief summary (as posted)
Breast cancer is the most frequent in women. Early diagnosis and recent treatments have improved overall mortality. However, chronic pain (pain lasting more than 3 months after surgery) remains a public health problem with impact on quality of life for these patients. The incidence of pain has been reported up to 25 to 60% of patients in the literature, even many years after a radical mastectomy. The neuropathic component of the pain is usually underestimated. In a prospective cohort study we have demonstrated that 43% of patient needed on average 5mg of morphine intravenously in the recovery room after a conservative breast cancer surgery, despite a multimodal regimen of analgesic drugs. In the same study, 40% of patients reported persistent pain 3 months after the surgery. To improve the analgesia in such a population, we decided to introduce regional analgesia technique (serratus block) systematically. This became our gold standard in our daily practice. We would like to assess the efficacy of such regional analgesia techniques on opioids consumption in the recovery room and the incidence of pain 3 months after conservative breast cancer surgery.
