Veterinary anaesthesia and analgesia
-
Randomized Controlled Trial
Desaturation times between dogs preoxygenated via face mask or flow-by technique before induction of anesthesia.
To compare time to desaturation after induction of anesthesia following administration of oxygen via face mask or flow-by for 3 minutes. ⋯ Mask preoxygenation provided longer time to desaturation compared with the flow-by technique tested.

To evaluate an ultrasound-guided technique for adductor canal (AC) block by describing the distribution of methylene blue around the AC, popliteal fossa, saphenous, tibial and common fibular nerves in dog cadavers. ⋯ Although the tibial and common fibular nerves were not stained as often as the saphenous nerve, dye was encountered throughout the popliteal fossa near the nerves. The AC block may be useful for intra and postoperative analgesia in stifle surgery with minimal femoral motor dysfunction. However, further study is required to confirm its efficacy and safety in vivo.
