Case report: serratus intercostal plane block/BRILMA and sedation for mastectomy in a high risk patient. / Caso clínico: bloqueo serrato intercostal/BRILMA y sedación en mastectomía en paciente de riesgo.

Breast cancer surgery can benefit from regional anaesthesia techniques, which can be used as a sole anaesthetic procedure in some cases where risk for general anaesthesia is high. Regional anaesthesia allows early recovery, reduces postoperative opioid and non opioid analgesics consumption and helps early home discharge, reducing thus costs. We present a case of an 87-year-old woman with multiple comorbidities who underwent breast cancer surgery. The patient was successfully surgically treated under serratus intercostal plane block anaesthesia. We discuss the use and benefits of the serratus intercostal plane block in thoracic procedures.
