Resumo
The aim of this study was to evaluate the effect of the tranquilization with acepromazine and fentanyl intramuscularly, alone or in combination, and oral acepromazine on the echocardiographic parameters, besides its action as a facilitator of the echocardiographic examination (ECHO). Ten adult Rottweiler dogs were randomly grouped and distributed in a Latin square design. Each pair was submitted to different tranquilizing protocols, 20 minutes before the echocardiographic evaluation, totaling five treatments for each pair, performed at seven-day intervals between the evaluations. The treatments were: TC (control treatment), TA (intramuscular acepromazine), TAO (oral acepromazine), TF (fentanyl) and TAF (acepromazine associated with fentanyl). In addition to the echocardiographic parameters, the degree of reassurance, duration of the exam, heart rate (HR) and respiratory rate (RF) in the different protocols were evaluated. There was a significant reduction in left ventricular diameter in systole and diastole (DIVEs and DIVEd), systolic excursion of the annular tricuspid plane (ESPAT), mitral annular movement (MAM) and mitral E / mitral A ratio (E / A ratio) . There was a decrease in PASS in all protocols, however, it was only significant in TAO. TAO and TA were the protocols that made the echocardiographic examination easier to perform because of a greater degree of reassurance, a decrease in HR and RF, and consequently a reduction in the time of examination. It is concluded that acepromazine used alone orally or intramuscularly, is a good protocol to promote tranquilization during the ECHO in healthy dogs, however, it has a tendency to decrease the PASS and may alter the echocardiographic parameters dependent on the pre-charge. Fentanyl used alone or in combination does not facilitate echocardiographic examination in dogs.
