Perioperative analgesic efficacy of quadratus lumborum block versus transversus abdominis plane block in dogs undergoing laparoscopic ovariectomy: a prospective randomized clinical trial

Both TAPB and QLB guaranteed adequate analgesia regarding the somatic stimulus (T1) compared to P whereas all groups were not able to prevent a cardiovascular response during the induction of capnoperitoneum (T2) and ovarian traction (T3-T4). Analgesia in the early postoperative period (up to 4 h) was adequate in all groups.
