Continuous Erector Spinae and Serratus-Intercostal Block With Ketamine-Dexmedetomidine Sedation for Quadrantectomy and Axillary Dissection in a Multimorbid Patient

Multimorbidity is a clinical presentation that poses an increased risk of perioperative and postoperative complications. Tailored anaesthetic management could potentially minimise the risk of negative outcomes. Peripheral nerve and fasciae blocks are valid strategies for perioperative and postoperative pain management, which avoid complications related to general anaesthesia and reduce the risk of intensive care unit admission as well as the hospital length of stay. We describe the case of a 56-old patient with multimorbidity, including obesity with a BMI of 45.7, unstable angina, predicted difficult airway management and obstructive sleep apnoea syndrome (OSAS) scheduled for left mastectomy with sentinel lymph node biopsy, managed with a left continuous thoracic erector spinae plane (ESP) block plus serratus-intercostal plane block (BRanches of Intercostal nerves at the Level of Mid-Axillary line (BRILMA)), and sedation with combined ketamine-dexmedetomidine. Fascial blocks combined with opioid-free anaesthesia (OFA) proved to be effective for the multimorbid patient, ensuring successful perioperative management and a proper recovery after surgery.
