Abstract :This study evaluated the analgesic efficacy of different sedative-lidocaine combinations and the applicability of ultrasonography (USG) guided bilateral rectus sheath block (RSB) for pain control before and after umbilical hernia (hernia umbilicalis) surgery in neonatal calves. Thirty healthy calves, aged between 0 and 3 months, presented to the Harran University Veterinary Faculty Animal Hospital for umbilical hernia and were randomly allocated into five groups. The groups received the following combinations: xylazine–lidocaine (XY), dexmedetomidine–lidocaine (DE), medetomidine–lidocaine (ME), midazolam–lidocaine (MI), and butorphanol–lidocaine (BU). All preanesthetic agents were administered intravenously (IV), followed by subcutaneous lidocaine infiltration and ultrasound (US) guided bilateral RSB. Analgesic efficacy was evaluated using the Bovine Pain Assessment Scale and the Visual Analog Scale (VAS) at 0, 30, 45, 60, 120, and 240 min after the calves stood up. Surgical procedures were completed without complications in all groups, and no statistically significant difference was observed between the operation times (P >0.05). In the XY and MI groups, the analgesic effect was observed to have an early onset and was long lasting and stable. Although analgesia was initially effective in the BU group, it slightly decreased over time. The duration of analgesia was shorter in the ME group. In the DE group, a moderate level of stability was achieved; however, high pain scores were recorded. No systemic complications developed in any of the patients. This study demonstrated that the USG guided RSB technique is a safe and effective analgesic method for calves. XY and MI protocols provide prolonged and stable analgesia, whereas the BU protocol may be considered a suitable option for short-term surgical procedures. These findings are clinically instructive for identifying practical and effective analgesia protocols that are applicable to field conditions.
