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.
