Abstract

This prospective randomised clinical trial evaluated the effect of warmed irrigation fluid on body temperature in anaesthetised dogs undergoing arthroscopic elbow surgery. Nineteen dogs undergoing elbow arthroscopy were included in the study and were randomly allocated to one of two groups. Group RT received irrigation fluid at  room temperature (RT) while dogs in group W received warmed (W) irrigation fluid (36oC). A standardised  patient management and anaesthetic protocol was used and body temperature was measured at four time  points; (T1) pre-anaesthetic examination, (T2) arrival into theatre, (T3) end of surgery and (T4) arrival into  recovery. There was no significant difference in body temperature at any time point between the groups. The mean overall decrease in body temperature between pre-anaesthetic examination (T1) and return to the  recovery suite (T4) was significant in both groups, with a fall of 1.06±0.58oC (p<0.001) in group RT and  1.53±0.76oC (p<0.001) group W. There was no significant difference between the groups. At the end of  surgery (T3) 4/19 (21.1%) of dogs were hypothermic (<37oC). The addition of warmed irrigation fluids to a  temperature management protocol in dogs undergoing elbow arthroscopy during general anaesthesia did not lead to decreased temperature losses.
