Evaluation of the rectal‐interdigital temperature gradient as a diagnostic marker of shock in dogs

摘要: OBJECTIVE To evaluate the difference in rectal-interdigital temperature gradient (RITG) between dogs that were presented to an emergency room with clinical signs of shock compared those without shock, and if this can be used as a diagnostic marker for shock. DESIGN Prospective, single center, observational study conducted from 2014 2015. SETTING University veterinary teaching hospital. ANIMALS Twenty diagnosis 60 (controls). MEASUREMENTS AND MAIN RESULTS Upon presentation prior intervention, measurements rectal temperature, interdigital ambient systemic markers perfusion (capillary refill time [CRT], heart rate [HR], respiratory [RR], Doppler blood pressure [DBP], venous plasma lactate concentration), gas analytes recorded. Dogs initially determined by attending clinician, post hoc inclusion criteria applied. Shock was defined abnormalities ≥3 6 following criteria: HR > 120/min, RR > 40/min, CRT > 2 seconds, temperature  2.5 mmol/L, or DBP < 90 mm Hg. Animals circulatory had significantly increased RITG. An RITG also correlated individual parameters including prolonged CRT (ρ = .353, P = 0.0013), tachycardia = .3485, 0.0015), decreased DBP = -0.6162, 0.0003), index = 0.6168, 0.0003). Receiver operator curve analysis indicated cutoff point 11.6°F 90% specificity (area under curve = 0.7604). CONCLUSIONS The associated therefore may serve Future studies larger sample sizes validate use gradients other peripheral monitoring tools are warranted.
