Fetal Canulation.

Fetal Canulation.
The 4-month old fetuses of these ewes have been cannulated via their carotid artery. The cannulas have been exteriorized via the flank of the ewe and placed in a protective pouch. Fetal blood can be sampled at predetermined times and frequency. Notice the orientation of the diagonal incision in the lower left flank in ewe 134.
