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...

Doppler echocardiography in a healthy, non-sedated Southern Sea Lion (Otaria flavescens) - a preliminary approach about the feasibility and clinical utility
AbstractEchocardiography is commonly used in veterinary clinical practice for many species but is not as easily applied in non-sedated marine mammals. Additionally, Doppler echocardiography provides further information on hemodynamics, estimation of cardiac output, characterization of flow patterns, and diastolic function. However, its applications in marine mammals have not been as widely explored either. The present report aimed to characterize the left ventricle structure and function of the Southern Sea Lion (Otaria flavescens) through a Doppler echocardiography study. Data were obtained from a healthy animal trained f...

Animal protection and mass depopulation
Can Vet J. 2022 Aug;63(8):859-862.ABSTRACTThis case study-based paper outlines the thought processes linked to the ethical decision in Canadian animal protection work, about when a case warrants investigation as an offence under provincial animal protection legislation and when it is a criminal code offence. Conflict of laws and jurisdiction as well as prosecutorial discretion give us cause to consider whether methods of mass depopulation of animals in emergency situations can breach prohibitions against animal cruelty. The current practice of overheating enclosed holding facilities to intentionally kill pigs by induced he...
