Use Of A Low Concentration, High Volume Erector Spinae Plane Block For Rescue Analgesia After Melanoma Resection And Axillary Sentinel Lymph Node Biopsy

The erector spinae plane block (ESPB), a recent innovation in regional anesthesia, has been used for analgesia of the thorax and chest. The case presented describes the use of an ESPB postoperatively for rescue analgesia on an elderly, opioid-naive patient, who had severe postoperative pain after outpatient surgery at an axillary sentinel lymph node biopsy site refractory to escalating IV opioid doses. The rescue ESPB was successful in reducing the patient's pain to 0/10, allowing the patient to be discharged home and preventing a costly hospital admission.
