Question 1

Use of vasopressors for treatment of vasodilatory hypotension in dogs
Murphy_2022_JVECC

Answer 1

For both dogs and cats, the most common first-line vasopressor was nore- pinephrine (87.9% in dogs and 83.1% in cats). The most common second-choice vasopressor was vasopressin (44.2% in dogs and 39.0% in cats). Cutoff values for initiating vasopressor therapy varied between species and modality used for blood pressure measurement. In general, most DACVECCs chose to initiate vasopressor therapy at a Doppler blood pressure <90 mm Hg or a mean arterial pressure of <60 or <65 mm Hg when using oscillometric or direct arterial blood pressure measurements in dogs and cats.

Question 2

Retrospective evaluation of jugular venous blood variables and mortality in critically ill hospitalized cats
Donati JVECC 2022

Answer 2

In cats with hemodynamic instability and tissue hypoperfusion, HCT and PvjO2 behaved as independent predictors of mortality. Both variables seem to reflect the magnitude of oxygen debt and tissue hypoperfusion.
