ABSTRACT: Proper monitoring of cardiac index (CI) in critically ill patients requires accurate and minimally invasive methods. The aim of this study was to compare the CI values obtained by thermodilution or echocardiography using different methods in dogs in different hemodynamic states. Nine dogs weighing 19.6±1.3kg were anesthetized with isoflurane at 1.4V% (Baseline) and subjected to mechanical ventilation (MV),a hypodynamic state (Hypo) with isoflurane at 3.5V% and hyperdynamic state (hyper) with dobutamine infusion at 5μgkg-1min-1. CI analysis was performed by thermodilution (TD) and using the modified Simpson's method, aortic velocity-time integral (A-VTI) method and pulmonary VTI (P-VTI) method. We performed Pearson's correlation and Bland-Altman...

Cardoso,Helena Mondardo; Tocheto,Ronise; Padilha,Vanessa Sasso; Silva,Gizelli; Comassetto,Felipe; Andrade,James Newton Bizetto Meira de; Oleskovicz,Nilson.
ABSTRACT: The objective of this study was to investigate the echocardiographic changes during anesthesia induction in dogs sedated with acepromazine (0.05mg/kg) and butorphanol (0.3mg/kg) (AB). Twenty-four male dogs, with a mean weight of 12.40kg±3.1kg, were randomly assigned to 4 groups (n=6). Fifteen minutes after administering pre-anesthetic medication, anesthesia with diazepam (0.5mg/kg) and etomidate (1mg/kg) (group DE); diazepam (0.5mg/kg) and ketamine (3mg/kg) (group CD); propofol (4mg/kg) (group P); or ketamine (1mg/kg) and propofol (3mg/kg) (group CP) was administered to the 6 dogs in each group. Systolic blood pressure (SBP) was measured and echocardiography was performed immediately prior to the application of the sedation protocol (baseline),...

Efeitos cardiovasculares e analgésicos da administração epidural de ropivacaína isolada ou associada à morfina, em felinos Ciência Rural
Regalin,Doughlas; Moresco,Marina; Padilha,Vanessa Sasso; Tocheto,Ronise; Oleskovicz,Nilson.
Visando avaliar os efeitos cardiovasculares e analgésicos de dois protocolos epidurais em felinos submetidos à OSH, 16 gatas mestiças, adultas, que, após indução à anestesia geral, receberam anestesia epidural (L7 - S1) com 0,26mL kg-1 de ropivacaína 0,75%, isolada (GR) ou associada a 0,1mg kg-1 morfina (GRM). A ETCO2, f, FC, PAS, T°R e relaxamento muscular foram avaliados no momento basal, 30 minutos após epidural, após incisão de pele, ligadura dos pedículos ovarianos e cérvix, final da celiorrafia e cirurgia, sendo administrado fentanil, caso ocorresse aumento de 20% na PAS, FC ou f em relação ao momento basal. Ao final do procedimento, foram avaliados, com auxílio de uma escala multidimensional de dor aguda em felinos, durante 12 horas, e, quando a...

Electrocardiographic, echocardiographic, and indirect blood pressure evaluation in dogs subjected to different sedation protocols Ciência Rural
Cardoso,Helena Mondardo; Padilha,Vanessa Sasso; Tocheto,Ronise; Regalin,Douglas; Gehrcke,Martielo Ivan; Oleskovicz,Nilson.
ABSTRACT: The present study aimed to evaluate the effects of different sedation protocols on blood pressure and echocardiographic and electrocardiographic parameters in dogs. In total, 24 male mixed-breed dogs with a mean weight of 9.87±3.0kg were used.Animals were randomly divided into four groups (n=6), which were subjected to sedation using the following protocols: acepromazine (0.05mgkg-1) and butorphanol (0.3mgkg-1) (AB); acepromazine (0.05mgkg-1)and methadone (0.5mgkg-1) (AM); acepromazine (0.03mgkg-1), methadone (0.5mgkg-1), and midazolam (0.3mgkg-1)(MAM); and methadone only (0.5mgkg-1) (M). Indirect blood pressure (BP) measurements and computerized electrocardiography (ECG) and echocardiography (ECO) were performed immediately before the...
