Comparison between Bilateral Ultrasound-Guided Quadratus Lumborum Block and Sacrococcygeal Epidural in Cats Undergoing Ovariectomy.

ABSTRACT:

Background

Ultrasound-guided quadratus lumborum block (QLB) and sacrococcygeal epidural anaesthesia (ScE) have been used for neutering cats, providing effective pain relief.

Objectives

To compare the effects of the QLB with those of ScE in cats undergoing ovariectomies.

Methods

Feral cats undergoing ovariectomy were premedicated with dexmedetomidine (20 μg kg^-1) and methadone (0.2 mg kg^-1) intramuscularly. Anaesthesia was induced with 2-4 mg kg^-1 of propofol intravenously and maintained with isoflurane in oxygen. The cats were randomly allocated to the groups QLB (bilateral QLB with 0.4 mL kg^-1 of 0.25% bupivacaine) and ScE (0.3 mL kg^-1 of 0.25% bupivacaine). Hemodynamic data and analgesia rescue were collected at
