Infrared thermography following castration, otectomy and gastrotomy in Nigerian indigenous dogs

Abstract

Infrared thermography analyzes changes in the surface temperature of the skin and has been used in companion animals to identify inflammatory processes, neoplasia, pain, and neuropathies. This study evaluated and compared surgical wound surface temperatures in Nigerian Indigenous Dogs (NID). Nigerian indigenous dogs are a medium-sized breed that weighs between 8 to 30 kg with moderate hair length, and a mesocephalic cranial index. The dogs were randomly allocated into groups A, B, and C for castration, otectomy, and gastrotomy, respectively. The wound surface temperature (WST) in the NID that underwent gastrotomy were significantly higher particularly at 18-48 h compared with Pre and other sampling periods within the group. It was also found that, at 0 h versus 48 h, 18 h versus 48 h, week 1 versus 18h; 24h; 48h; and 72h showed significant (p < 0.05) differences among NID subjected to gastrotomy (group C). However, the WST of NID subjected to castration and otectomy were significantly higher than that of gastrotomy. At 48 and 72 h, and week 1, the WST of NID in otectomy also known as ear cropping (group B) and castration (group A) were significantly (p < 0.05) higher than that of gastrotomy (Group C). Thermography of the surgical wounds aided postoperative wound management in the NID that underwent castration, otectomy and gastrotomy. Hence, the study suggests that guided WST with the aid of infrared thermography could be deployed as a useful tool to aid post operative wound management.
