Use of subcostal and lateral transverse abdominal plane blocks as part of multimodal analgesia in a calf undergoing omphalitis surgical correction

This report describes the combined use of the ultrasound-guided subcostal and lateral transversus abdominis blocks as part of the multimodal analgesia in a 3-month-old calf, presented for omphalitis surgical repair. It was premedicated with xylazine, anaesthesia was induced with ketamine and maintained by isoflurane in oxygen. The block was performed with lidocaine 2%, and flunixin meglumine was administered pre- and postoperatively. Postoperative pain was scored, and rescue analgesia was not required intra- and postoperatively. Pain assessment and multimodal analgesia are crucial in food-producing animals. Employing bilateral ultrasound-guided lateral and subcostal transversus abdominis plane block can prove advantageous as part of the multimodal analgesia protocol for calves undergoing umbilical surgeries. Furthermore, it is essential to delv into the discussion of lidocaine's toxic dosage when applied in locoregional techniques.
