“…The oral mucosa of the inner lip was selected as the site of CRT assessment in this study as it is a common and easily assessable site in dogs. Although the gingival mucosa has been used in previous canine studies, 45,53 the authors opted against its use for standardization as inflammatory changes may accompany severe gingivitis and alter focal CRT measurements. Lack of a stopwatch to quantify CRT measurement has been shown to impair reliability, 27 and repeated measurements at the same site have been shown to result in significantly shorter CRTs on repeat evaluations 3,9 .…”

“…Subsequently, Spearman's rank correlation was used to identify potentially significant associations ( P < 0.2) between dichotomous, ordinal, and continuous variables of interest and the categorized CRT groups to determine whether potential subgroups represented ranges of normal or abnormal CRTs. Based on the mean CRT reported by Obiorah et al 45 . in apparently healthy dogs, potential associations with the dichotomized variable of a CRT of either <1.3 or ≥1.3 seconds were also investigated.…”

“…The goal of the last was to investigate potential reference values for CRT that may have clinical significance. Based on the mean CRT reported by Obiorah et al 45 . in apparently healthy dogs, potential associations between hemodynamic variables of interest and a dichotomized variable of a CRT of either <1.3 or ≥1.3 seconds were also investigated.…”

Objective To assess the relationship between various physical and clinicopathologic parameters and the capillary refill time (CRT) using a standard method; to evaluate the influence of emergency room (ER) versus ICU hospital location on CRT; and to identify latent subgroups among the CRT distribution. Design Prospective, observational study. Setting University teaching hospital. Animals Client‐owned dogs in the ER (n = 40) and ICU (n = 71). Interventions The CRT was defined as the duration required for the oral mucosa of the upper lip to return to its original color after blanching for 4 seconds. The CRT was recorded in seconds to the 10ths place by a single observer using an automated recording device. Measurements and Main Results Median CRT for all dogs was 1.1 seconds (ER, 1.2 s; ICU, 1.1 s; P = 1.000). The CRT was significantly associated with rectal temperature (P = 0.004), systolic blood pressure (P = 0.028), body weight (P = 0.031), mucous membrane color (P = 0.007), skin turgor (P = 0.039), and acute patient physiologic and laboratory evaluation mentation score (P = 0.019) for all dogs. The CRT was related to a greater number of variables in the ER than in the ICU patient population. In general, the total population of dogs had CRTs belonging to 1 of 2 groups: either ≤1.2 or ≥1.7 seconds. A statistically significant association was found between body weight CRT ≥1.3 seconds (P = 0.02). Conclusions A CRT following blanching for 4 seconds may provide insight into the hydration status and hemodynamic stability of canine patients. Further research into its clinical application is warranted.
