Abstract

Ropivacaine tumescent anaesthesia was evaluated for the surgical management of mammary gland tumors in dogs using a randomized  study design involving two groups, each comprising six female dogs diagnosed with mammary tumors. Group I received tumescent  infiltration with ropivacaine, adrenaline, and Ringer lactate prior to mastectomy, while Group II underwent excision without tumescent  anaesthesia. Intraoperative pain control was assessed via heart rate monitoring and postoperative pain was evaluated with a  multidimensional composite pain scale. Dogs treated with ropivacaine tumescent solution showed markedly reduced intraoperative  bleeding, stable cardiovascular parameters, and significantly lower pain scores during recovery compared to the control group  (p<0.05). The addition of adrenaline enhanced vasoconstriction, further minimizing blood loss and prolonging anaesthetic effect at  the surgical site. Ropivacaine tumescent infiltration offered robust and prolonged analgesia, reduced the need for systemic analgesics,  and supported smooth postoperative recovery. This technique demonstrates that ropivacaine tumescent anaesthesia is an effective,  safe, and practical option for canine oncologic mammary surgery, supporting multimodal anaesthesia protocols for optimal pain control  and surgical outcomes.
