Veterinary anaesthesia and analgesia
-
To describe an ultrasound-guided thoracic paravertebral block and determine the distribution after injection of two volumes of methylene blue in dog cadavers. ⋯ Ultrasound-guided injection at the thoracic paravertebral space resulted in staining of the spinal nerve in all dogs. However, T5 paravertebral space was not accurately identified using anatomic landmarks. Dye distribution was not significantly different between the two groups; therefore, the use of the lower-volume and multiple-site injections would be potentially necessary in clinical cases to achieve ipsilateral blockade of the thoracic wall.

Randomized Controlled Trial
Impact of Trendelenburg (head down) and reverse Trendelenburg (head up) position on respiratory and cardiovascular function in anaesthetized horses.
To describe the cardiorespiratory effects of a change in table position in anaesthetized horses. ⋯ Gas exchange is better preserved in HU compared to HD, especially if applied from the start of the anaesthesia.
