Fig 5. The acceleration in emergence from anesthesia was maintained even after an 11 week hiatus where rats were not transported or handled in any manner.

This group of 8 rats was anesthetized with 3% isoflurane for 60 minutes (4 L/ min O₂), ten times (weeks 1–10). At that time the animals were left untouched for the following 11 weeks (hiatus). Plotted are the average recovery times observed at week 10 (504 ± 32.4), prior to the hiatus and at week 21 after the 11 week hiatus (560.9 ± 84.6). Recovery times were not different after the hiatus when compared to before the hiatus (p = 0.52). The raw data is plotted as a scatter to the left of each bar chart.
