Abstract

The present study aimed to compare the postoperative analgesic effects of lignocaine alone and in combination with dexmedetomidine in 18 female dogs undergoing ovariohysterectomy. The animals were randomly divided into three groups (n=6 each). Premedication was done using atropine sulphate followed by midazolam, and anaesthesia was induced and maintained with 1% propofol in all animals. In the control group (O), a normal saline infusion was maintained. In group L, a loading dose of lignocaine followed by continuous rate infusion (CRI) was administered, whereas in group LD, a loading dose of lignocaine combined with dexmedetomidine followed by their CRI was given throughout the surgery. Pain assessment was performed using the UMPS and GCMPS-SF pain scales. The results indicated that intraoperative administration of lignocaine, both alone and in combination with dexmedetomidine, significantly reduced postoperative pain in dogs undergoing ovariohysterectomy, with a greater analgesic effect observed when lignocaine was combined with dexmedetomidine.
