Abstract/OtherAbstract:
This study examines the effects of changing oxygen fractional inspiration ratio (FiO(2)), and nitrous oxide (N(2)O) for the improvement of cardiovascular control of mean arterial blood pressure (MAP) and heart rate (HR) in C57BL/6 mice under isoflurane anesthesia (1.5%) for up to 90 minutes post-induction. Heart rate variability (HRV) indices are also quantified under these conditions. The results indicate that changing the FiO(2) does result in lower MAP and HR values compared to the case of N(2)O (50%) administration to the isoflurane gas mixture. HRV indices declined over the course of all anesthetic regimens, suggesting a decrease in parasympathetic tone. We conclude that the most optimal anesthetic condition is achieved when N(2)O (50%) is added to the gas mixture.
