Esophageal Doppler-derived indices and arterial load variables provide useful hemodynamic information during assessment of fluid responsiveness in anesthetized dogs undergoing acute changes in blood volume
Am J Vet Res. 2023 Feb 1:1-11. doi: 10.2460/ajvr.22.11.0198. Online ahead of print.ABSTRACTOBJECTIVE: To investigate the relationship between invasively measured stroke volume (SV) and (1) esophageal Doppler-derived indices such as stroke distance (StrokeD), flow time corrected (FTc), stroke distance variation (SDV), and peak velocity variation (PVV); and (2) arterial load (AL) variables during evaluation of fluid responsiveness (FR) in anesthetized dogs undergoing sudden hemodynamic shifts in blood volume.ANIMALS: 6 healthy male dogs.PROCEDURES: Dogs were anesthetized with isoflurane, ventilated mechanically, and instrume...

Effects of a flotation vest and water flow rate on limb kinematics of Siberian Huskies swimming against a current
CONCLUSIONS AND CLINICAL RELEVANCE: In dogs, range of motion during swimming was greater for the carpus than tarsus, when an FV was not worn, and increased more with WFR when WFR was incrementally increased. Those factors should be considered during swimming-based rehabilitation.PMID:34727070 | DOI:10.2460/ajvr.21.02.0021

Investigation of the influence of manual ventilation-controlled respiration on right ventricular pressure-volume loops and echocardiographic variables in healthy anesthetized dogs
CONCLUSIONS AND CLINICAL RELEVANCE: Specific RV echocardiographic variables were significantly affected by respiration. In contrast, RVS and RVSR determined with RVGA were not affected by respiration and were associated with hemodynamic indicators of RV contractility.PMID:34669489 | DOI:10.2460/ajvr.82.11.865
