abstract
Dogs having mammary tumours (unilateral or bilateral) belong to different breeds, aged between 4.5 to 13 years with a body weight ranged between 10 to 44 kgs were utilized for the study. Following premedication dogs were sedated with glycopyrrolate and acepromazine and were subjected to propofol anaesthesia. After stabilization of anaesthesia and monitoring, the animals were divided in to two groups of six animals each. Group I animals were subjected to tumescent anaesthesia and group II animals were given fentanyl analgesia for mammary tumour excision. Physiological, haematological and bio chemical parameters were recorded and analyzed. The mean induction time of propofol was 21± 0.516 seconds in both groups. Induction quality was excellent, smooth and rapid without struggling in all animals. Tumor excision time and intraoperative bleeding was less in dogs subjected to tumescent anaesthesia. TA is apparently safe for use in clinical conditions as it did not produced any adverse signs or lignocaine toxicity and facilitated the surgical procedure because of reduced bleeding and a shorter mammary gland removal time without interfering with wound healing.
