title: [Echocardiographic reference ranges of sedated cats].
abstract: The aim of this study was to get echocardiographic values of sedated healthy cats of the race European short hair for further reference. After the preliminary examinations checking on the state of health (anamnesis, general and special clinical examinations, ECG, X-ray of thorax and preparation of selected laboratory parameters), 74 sedated animals and additionally 33 cats without sedation were echocardiographically measured. For sedatives we used ketamine hydrochloride and xylazine in order to minimize defending movements of the animals and to reduce the heart rate, which facilitated the echocardiographical measurements. The covariance analysis of the measured values showed a statistically significant dependence on the weight. This did not hold for the two calculated values of the fractional shortening (FS) and the quotient of left atrium and aorta (LA/Ao), where the weight-dependence of each component was compensated by the calculation of the quotient. All stated weight-dependent reference values refer to an average bodyweight of 4.0 kg. A dependence on the age did not show in the covariance analysis. Due to the sedation, the diameter of the left atrium (LA) and the diameter of the left ventricular lumen in the diastole (LVDd) as well as the fractional shortening decreased significantly.
