Effects of Isoflurane Anesthesia on the Hematologic Values of Rehabilitated Wild Owls
Isoflurane anesthesia is commonly used for owls when they are being rehabilitated to minimize stress during treatments and procedures, as well as to ensure caretaker safety.

Isoflurane anesthesia is commonly used for owls when they are being rehabilitated to minimize stress during treatments and procedures, as well as to ensure caretaker safety. However, the effects of isoflurane anesthesia on the hematologic response of owls are not known. To investigate the effects of isoflurane anesthesia on the hematology of owls, 3 phases of investigation were performed on the subject animals: 1) single, short manual- versus single, short isoflurane-restraint episodes (n = 12; 38%); 2) a single, prolonged isoflurane episode (n = 10; 31%); and 3) serial, short isoflurane episodes (n = 10; 31%). All owls were classified as adult, and the sex for most individuals was unknown. Twelve owls (38%) were included in phase 1: 5 great horned owls (; 42%), 2 eastern screech owls (; 17%), and 5 barred owls (; 42%). A separate cohort of 10 novel owls (31%) were selected for inclusion in both phases 2 and 3: 4 great horned owls (40%), 2 eastern screech owls (20%), 2 barred owls (20%), 1 barn owl (; 10%), and 1 snowy owl (; 10%). For each anesthetic episode, blood was collected within 3 minutes of capture and in 15-minute intervals according to the duration of the procedure.
