What doses of Ketamine & Xylaxine (Rompum) should be administered for
30-45min deep anesthesia during stereotaxic surgery in adult male Long
Evans rats (300-400g)? I have been using 100mg/Kg Ketamine ip and
15mg/Kg Xylaxine im with good results up until now. It is the
strangest thing. We seem to lose a lot of animals after 5pm (the
animals are kept on a 12:12 reverse light/dark schedule). Does anyone
else find this temporal hypersensitivity in rodent anesthesia? Any
suggestions for different doses or using another anesthetic agent?
