Body temperature loss during ketamine/xylazine anesthesia of 3-week-old (<i>filled circles</i>) versus 3-month-old (<i>open squares</i>) C57BLKS/J mice.

<p>Immediately upon anesthesia, mice were placed on the OCT platform for 2.5 minutes and then given indirect heat for the remainder of the experiment. There is no significant difference (<i>P</i> > 0.05 at all time points, unpaired <i>t</i>-tests) in body temperature loss between young (small) and adult (large) mice (<i>n</i> = 3 mice per group). Error bars are standard deviation.
