Comparison of canine capillary and jugular venous blood lactate concentrations determined by use of an enzymatic-amperometric bedside system

Abstract

Because of the lack of agreement between lactate concentrations determined in capillary and jugular venous blood samples, measurement of capillary blood lactate concentration in dogs performed with the technique used in the study does not appear to be a reliable alternative to jugular venous blood measurements.

The preanalytic phase in veterinary clinical pathology

“…Samples collected from the tail vessels in cows can sometimes yield a mixture of venous and arterial blood inappropriate for blood gas determinations, and inorganic phosphate concentrations have been reported to be higher in tail specimens than jugular vein specimens . In cats and dogs, specimens collected from ear capillaries can notably differ from those obtained from a large vein, for example, HCT and plasma proteins in cats, and plasma lactate concentration in dogs . In rats, HCT, RBC, and WBC counts were reported to be higher in blood collected by terminal heart puncture than by in life orbital sinus or tail vein collection, whereas MCV and MCH were identical .…”

Clinical use of plasma lactate concentration. Part 1: Physiology, pathophysiology, and measurement

“…In healthy dogs, small but statistically significant differences were found between samples from the cephalic vein, jugular vein, and femoral artery, while no significant difference was noted between samples obtained from the jugular vein, lingual vein, and dorsal pedal artery . In contrast, in a convenience sample of dogs referred to a university veterinary hospital, the association between jugular venous and capillary (pinnal) lactate was poor . Samples from the medial saphenous and jugular veins have been shown to be comparable in healthy cats .…”
