Comparison of transverse facial venous sinus and jugular blood values in healthy and critically ill horses.
Abstract: The transverse facial venous sinus (TFVS) can be used for blood collection in horses, but information on the validity of blood values from this site is limited. Objective: To determine if packed cell volume (PCV), total solids (TS) and blood lactate concentrations in blood drawn simultaneously from a TFVS and jugular vein of critically ill horses are correlated and determine the effect of serial TFVS sampling on the same parameters in healthy horses. Methods: Prospective observational study. Methods: Critically ill horses had simultaneous blood samples drawn from a TFVS and jugular vein. Blood was also drawn from the left TFVS and jugular vein from 6 healthy, adult horses q. 6 h for 24 h, then q. 24 h for 72 h. Blood was drawn from the right TFVS and jugular vein q. 24 h for 96 h. All samples were analysed for PCV, TS and blood lactate concentration. Data were analysed with 2-way repeated measures ANOVA. Significance was set at P≤0.05. Results: There were no significant differences in PCV, TS or blood lactate concentrations of TFVS samples compared with jugular blood in critically ill horses. Serial TFVS sampling in healthy horses had no significant effect on TS or blood lactate concentrations. Although PCV in the TFVS was significantly lower than in jugular blood on serial sampling, the difference was not considered clinically relevant. Conclusions: Packed cell volume, TS and blood lactate concentrations were comparable between the TFVS and jugular vein.

The study investigates the validity of using blood collected from the transverse facial venous sinus (TFVS) of horses for analysis of packed cell volume, total solids, and blood lactate concentrations, in comparison to blood samples obtained from the jugular vein. The results showed no significant differences in these parameters between the TFVS and jugular blood samples in both critically ill and healthy horses.
Objective and Methodology
- The aim of this research was to determine if the blood drawn from the transverse facial venous sinus (TFVS), an easily accessible site for blood collection in horses, produced equivalent values for packed cell volume (PCV), total solids (TS), and blood lactate concentrations as blood drawn simultaneously from a jugular vein of critically ill horses.
- The researchers also wanted to establish if repeated blood withdrawal from the TFVS affected these parameters in healthy horses.
- This investigation was a prospective observational study, wherein a group of critically ill horses had blood samples concurrently extracted from their TFVS and jugular vein.
- In addition, blood was also harvested from both sites of healthy adult horses at varying intervals over a 96 hour period.
- All the samples were tested for PCV, TS, and blood lactate concentration, and the data were analysed using a statistical technique called two-way repeated measures analysis of variance (ANOVA).
Results and Conclusion
- Analyses of the values obtained from the tests revealed no significant changes in the PCV, TS, or blood lactate concentrations in the samples taken from the TFVS compared to the jugular blood in the critically ill horses.
- In addition, results showed that repeated TFVS sampling in healthy horses had no significant impact on TS or blood lactate concentrations.
- However, the PCV value in the TFVS blood was considerably lower compared to the jugular blood in serial sampling, but this difference is not seen as clinically significant.
- The study concludes that there are no significant disparities in the values of packed cell volume (PCV), total solids (TS) and blood lactate concentrations between the blood from the TFVS and the jugular vein, making the TFVS a reliable site for blood collection in horses, both healthy and critically ill.
