Erector Spinae Plane Block (ESPB) or Quadratus Lumborum Block (QLB-II) for laparoscopic cholecystectomy: Impact on postoperative analgesia

• Both ESPB and Quadratus Lumborum Block type II (QLB-II) can be used laparoscopic cholecystectomy (LC). • NRS scores were lower in the ESPB group at 1st hour only. • There was no difference between overall NRS scores and opioid consumption between the groups. • ESPB and QLB-II are not significantly different in providing analgesia for LC.
