| description | Abstract Background Different methods to measure tissue perfusion are available in equine neonatology, but they are not representative of microvascular derangements. Objective To evaluate the feasibility of the sidestream dark‐field (SDF) capillaroscopy to visualize the capillary microvasculature in conscious newborn foals, the differences between two imaging sites and times of measurements, and the measurements' reproducibility. Methods Seventeen healthy newborn foals were enrolled. Three sites at the upper and lower lip mucosa were assessed by SDF, using a hand‐held capiscope, at 24 h and at 4–5 days after birth. Videos were assessed independently by two observers for quality and for semiquantitative calculation of microvascular parameters, including vascular density (VD), microvascular flow index (MFI), proportion of perfused vessels (PPV), and functional capillary density (FCD). Data were analyzed using unpaired and paired Student's T‐tests to assess differences between sites and time‐points. Bland–Altman plots and intraclass correlation coefficient (ICC) were used to assess measurement reproducibility. Results Differences were found between the upper and the lower lip for VD at both 24 h and 4–5 days, and for FCD at 24 h, and between the two time‐points for PPV at the lower lip. ICC for measurement reproducibility was good for all parameters (0.64–0.79) for the lower lip, and was good for VD and FCD (0,76–0,79) and fair to moderate for MFI and PPV (0.31–0.41) for the upper lip. Conclusions Measurement of the capillary microvasculature is feasible in the conscious newborn foal. The lower lip has the best measurement reproducibility. Further investigations are warranted in cardiovascularly compromised cases, particularly in septic foals. |
