Randomized Controlled Trial
Evaluation of serial venous and arterial lactate concentrations in healthy anesthetized sheep undergoing ovariectomy.
To determine if lactate concentrations in jugular venous and auricular arterial blood differ in anesthetized sheep. ⋯ Lactate concentrations were significantly lower in anesthetized sheep compared to non-anesthetized sheep. Lactate concentrations in venous blood were higher than in arterial blood. Therefore, anesthetic status and sampling site should be considered when interpreting lactate concentrations, and the sampling site should be consistent for repeated measurements.

To develop and evaluate a method for ultrasound-guidance in performing the proximal paravertebral block for flank anaesthesia in cattle through a cadaveric study, followed by clinical application. ⋯ Further research should be conducted to improve the ultrasound-guided technique described in this study.
