Erector spinae plane block in laparoscopic nephrectomy as a cause of involuntary hemodynamic instability: A case report

Abstract

The Ultrasound‐guided erector spinae plane block (US‐ESPB), used as an anesthesiological block for opioid‐sparing approach and for postoperative analgesia, could represent an involuntary cause of hemodynamic instability. This hemodynamic instability is accentuated by a greater diffusion of local anesthetic in the epidural space.
