Der volle Inhalt der QuelleBedside ultrasonography and the evaluation of dimensional variables of the caudal vena cava to assess volemic status in dogs are of growing interest in veterinary medicine. In this work, we describe a protocol for the ultrasound measurement of the caudal vena cava to aorta ratio (CVC:Ao), which allows us to overcome the variability in the size and weight of our patients. In this work, we first established a reference range of 0,93-1,32 for the CVC:Ao ratio in healthy dogs. The use of the CVC:Ao ratio was first studied in the dog presented with circulatory shock. The value of the CVC:Ao ratio was lower than the reference values described and increased with infusion of IV fluids. This ultrasound ratio seems to be of interest in the diagnostic and therapeutic management of circulatory shock in dogs. The CVC:Ao ratio was then studied in a group of dogs with acute kidney injury managed with extracorporeal renal replacement therapy (ERRT). The CVC:Ao ratio is not significantly increased in dogs with signs of fluid overload. The CVC:Ao ratio decreases significantly after RRT sessions. The CVC:Ao ratio, however, appears to be of lesser value in the evaluation of hypervolemic status. These results call for caution, and should be confirmed by future studies considering the small sample studied here.This ultrasound ratio is an index of the macrocirculation. In critical condition, the hemodynamic incoherence between the macro- and microcirculation is of great importance, and little studied in veterinary medicine. This work also validated the feasibility of studying the microcirculation with the Sidestream Dark Field (SDF) camera device in the sublingual region in healthy dogs in order to later study systemic hemodynamic and organ perfusion alterations in different pathological situations

Der volle Inhalt der QuelleA ultrassonografia duplex é actualmente o exame diagnóstico de eleição na avaliação da anatomia vascular e dinâmica de perfusão sanguínea. Em medicina veterinária a sua aplicação assume cada vez maior expressão, sobretudo nas espécies canina e felina. A progressiva popularidade do furão (Mustela putorius furo) como animal de companhia e a procura de cuidados médicos especializados potenciou a evolução da medicina. Até à data não existem registos da aplicação desta técnica no estudo de vasos sanguíneos nesta espécie. A inexistência de valores de referência limita o potencial diagnóstico. O principal objectivo deste estudo foi definir valores de referência para parâmetros hemodinâmicos na veia porta e cava caudal do furão, através do exame Doppler espectral sob anestesia com isoflurano. Pretendeu-se também avaliar qualitativamente o fluxo sanguíneo nestes vasos. O exame foi realizado na porta hepatis e a análise quantitativa envolveu o diâmetro (D), velocidade média (VF), fluxo sanguíneo médio (FS), índice de pulsatilidade (IP) e índice de congestão (IC). No total observaram-se 32 animais (16 fêmeas e 16 machos); um furão foi excluído devido a marcada replecção gástrica. O grupo A (n=17) incluiu animais clinicamente saudáveis e constituiu o grupo controlo. O grupo B (n=14) reuniu animais com patologia clinicamente comprovada. Devido a critérios de inclusão, a avaliação portal baseou-se apenas em 15 animais no grupo A e 13 no grupo B. No grupo controlo, observou-se fluxo uniformemente anterógrado na veia porta. O traçado espectral foi contínuo (padrão monofásico) com ligeiras oscilações respiratórias. Na veia cava caudal observou-se fluxo uniformemente anterógrado ligeira a marcadamente pulsátil e com pequenas oscilações associadas ao ciclo respiratório. Apenas um animal apresentou fluxo retrógrado no centro do vaso. Com base nos valores obtidos no grupo controlo calcularam-se os valores de referência (IC 95%). Na veia porta: D – 0.31-0.51 cm; VF – 14.30-24.97 cm/seg; FS – 1.50-5.92 ml/min/kg; IP – 0.12-0.28 cm/s; IC – 0-0.01 cm×s. Na veia cava caudal: D – 0.16 – 0.34 cm; VF – 13.42-30.42 cm/s; FS – 0.43-1.38 ml/min/kg; IP – 0.11-0.46 cm/s; IC – 0-0.01 cm×s. A comparação entre grupo A e B revelou diferença estatisticamente significativa do IP para ambas as veias (P=0,029 e P=0,032, respectivamente). Este projecto pioneiro disponibiliza novas informações sobre a biologia do furão e estabelece o ponto de partida para futuras investigações.
ABSTRACT - DOPPLER HAEMODYNAMIC EVALUATION OF PORTAL AND CAUDAL VENA CAVA IN MUSTELA PUTORIUS FURO: PRELIMINARY STUDY TO ESTABLISH REFERENCE VALUES - Duplex ultrasonography is currently the gold standard exam on vascular anatomy and haemodynamics. This technique has been increasingly used in veterinary medicine, particularly in cat and dog medicine. Ferret (Mustela putorius furo) medicine has been progressively evolving due to the rising popularity as a pet and the demand for specialized medical care. However, records of duplex ultrasonography examination of ferret’s blood vessels are inexistent. The lack of reference values limits its potencial as a diagnostic tool. The principal aim of the current study was to establish reference values for hemodynamic parameters of portal and caudal vena cava of ferrets. These parameters were measured with spectral Doppler in ferrets under isoflurane anaesthesia. It was also intended to qualitatively evaluate blood flow. All exams were performed at porta hepatis and the quantitative analysis included: diameter (D), median velocity (FV), median blood flow (BF), pulsatile (PI) and congestive index (CI). Thirty two animals were examined (16 hobs and 16 jills). One ferret was excluded owing to a marked increase in stomach volume. Group A (n=17) was the control group and included clinically healthy animals. Group B (n=14) was formed by clinically unhealthy animals. Due to inclusion criteria, portal vein exam included only 15 ferrets in group A and 13 in group B. The portal vein blood flow in group A was uniformly anterograde. The spectral waveform was continuous (monofasic pattern) with mildly respiratory oscillations. The caudal vena cava blood had a similar type flow but lightly to heavily pulsatile. The only exception was a ferret with retrograde flow in the center of the vein. The reference values of quantitative parameters were calculated from control group data with a CL of 95%. Portal vein normal values were: D – 0.31-0.51 cm; FV – 14,30-24,97 cm/seg; BF – 1,50-5,92 ml/min/kg; IP – 0,12-0,28 cm/s; IC – 0-0,01 cm×s. Caudal vena cava reference values were: D – 0.16 – 0.34 cm; FV – 13,42-30,42 cm/s; BF – 0,43-1,38 ml/min/kg; IP – 0,11-0,46 cm/s; IC – 0-0,01 cm×s. The haemodynamic parameters under evaluation were compared between group A and B. IP was statistically different between these two groups in portal (P=0,029) and caudal cava vein (P=0,032). This pioneer project gives new biological information on the ferret and is the beginning of future investigations in the field.

Der volle Inhalt der QuelleEstimar a volémia é essencial para o tratamento de pacientes críticos. Tradicionalmente, tal foi conseguido através de parâmetros indirectos ou métodos invasivos, como a Pressão Venosa Central (PVC). Recentemente, vários estudos em seres humanos demonstraram que a avaliação cinética das alterações respiratórias da Veia Cava Caudal (VCC) através de Ultrassonografia (US) pode constituir um indicador confiável da volémia, apresentando ainda a vantagem adicional de se correlacionar com a PVC. O objectivo deste estudo foi avaliar se a mesma correlação ocorre em cães normovolémicos, hipervolémicos e hipovolémicos. Todos os procedimentos foram aprovados pelo Comité de Ética da FMV. Quatro cães machos de raça indeterminada, peso vivo 19,3 ± 1,28 kg, 6,5 ± 0,58 anos e em estado hígido baseado no exame físico e exames complementares (análises de sangue, radiografia de tórax, eletrocardiograma, ecocardiograma e teste negativo para dirofilariose). Após a sedação do animal (acepromazina e butorfanol), um cateter venoso central 16 G (Certofix ® DuoSB 715 B|Braun) foi colocado assepticamente na veia jugular e a PVC foi medida com um manómetro de água. A VCC foi avaliada através US em modo M, com uma sonda linear de 7,5 MHz no 11º-12º espaços intercostais, com os animais em decúbito lateral esquerdo, durante a inspiração e expiração, no ponto onde a VCC entra na cavidade torácica e o volume sanguíneo (VS) medido pelo método colorimétrico de azul de Evans. Três tempos experimentais foram estabelecidos: S1 (normovolémia), S2 (hipervolémia induzida com um bolus Tetraspan 60mg/ml B|Braun® 10ml/kg) e S3 (hipovolémia induzida com recolha de 10% do VS). Determinou-se: o diâmetro máximo e mínimo da VCC em corte longitudinal (VCCmax L e VCCmin L) e em corte transversal (VCCmax T e VCCmin T), o índice da VCC (VCCi) CVCi = [(VCCmax-VCCmin) / VCC Max)] x 100 em diversos pontos ao longo do tempo para a correlação com os valores da PVC por meio de regressão linear e correlação de Pearson. As medições da VCC foram realizadas em todos os cães. S1. As Médias e Desvio Padrão obtidas foram (Med±DP): PVC (cmH2O) 3,58±2,67; VCCmaxL 0,94±0,34; VCCminL 0,69±0,3; VCCmaxT 0,87±0,28; VCCminT 0,64±0,2cm VCCi L 27,34±8,9%; VCCi T 29,67±10,0% e VS 86,9±9,5 ml/kg. S2. (Med±DP): PVC 5,66±2,03cmH2O; VCCmaxL 1,49±0,39cm; VCCminL 1,25±0,4; VCCmaxT 1,37±0,37 cm; VCCminT 1,12±0,3; VCCi L 19,26±10,11; VCCi T 20,53±10,76 e VS de 117,7±8,6 ml/kg. S3.

A VCC correlaciona-se melhor com o VS do que a PVC com o VS.
ABSTRACT - Ultrasound evaluation of caudal vena cava diameter changes with breathing as an estimate of volemia and central venous pressure - Estimating volemia is essential for the care of critical patients. Traditionally this has been achieved through indirect parameters or invasive methods such as central venous pressure (CVP). Recently several human studies demonstrated that ultrasound (US) kinetic respiratory changes of caudal vena cava (CVC) can be a reliable indicator of the volemic state and that it also correlates with CVP. The aim of this study is to assess if the same correlation occurs in normovolemic, hipervolemic and hipovolemic dogs. All procedures were approved by the Faculty of Veterinary Medicine´s Ethical Committee. Four crossbred, male dogs, with average weight 19,3±1,28 kg, 6,5±0,58 years old and healthy based on physical examination and diagnostic tests (blood analyses, thorax x-ray, ECG, echocardiography, and negative testing for dirofilariosis) were used. There were three sets of experiments, S1, S2 and S3. After animal´s sedation (acepromazine and buthorfanol), a 16 G central venous catheter (Certofix® DuoSB 715 B|Braun) was aseptically placed in the jugular vein and CVP was measured with a water manometer. CVC was assessed through US, with 7,5 Mhz linear probe at the 11-12th intercostal spaces with animal in left lateral recumbence; diameter was recorded in inspiration and expiration, through M mode, at the point where CVC enters in the thoracic cavity. Blood volume (BV) was measured by the Evans Blue colorimetric method. In S1 the parameters were measured without any volume changes (normovolemia). In S2 hypervolemia was induced by Tetraspan (60mg/ml B|Braun®) bolus administration (10ml/Kg). In S3 10 % of the calculated BV was removed to induce hypovolemia. Several parameters were determined: CVC maximum and minimum longitudinal diameter (CVCmax L and CVCmin L), CVC maximum and minimum transversal diameter (CVCmax T and CVCmin T) and CVC index (CVCi) CVCi=(CVC max-CVC min) / CVC max x100 at several time points for correlation with CVP values through linear regression and Pearson’s correlation coefficient. The CVC measurements with US were achieved in all dogs. S1. The obtained averages for each parameter were (Media±SD): CVP 3,58±2,67 cmH2O; CVCmaxL 0,94±0,34cm; CVCminL 0,63±0,3; CVCmaxT 0,87±0,28 cm; CVCminT 0,64±0,2; CVCi L 27,34±8,89; CVCi T 29,67±9,96 and BV of 86,9±9,5 ml/kg. S2: (Media±SD): CVP 5,66±2,03cmH2O; CVCmaxL 1,49±0,39cm; CVCminL 1,25±0,4cm; CVCmaxT 1,37±0,37 cm; CVCminT 1,12±0,3cm; CVCi L 19,26±10,11%; CVCi T 20,53±10,76% and BV of 117,7±8,6 ml/kg. S3: (Media±SD): CVP -1,04±1,36 cmH2O; CVCmaxL 0,63±0,24cm; CVCminL 0,39±0,2cm CVCmaxT 0,76±0,29cm; CVCminT 0,49±0,3cm; CVCi L 40,35±17,02; CVCi T 41,81±15,40 and BV of 82,7±4,1 ml/kg. CVC correlates better with BV than PVC with BV.

Introdução: A reposição volêmica em pacientes traumatizados tem sido controvérsa. O A.T.L.S. recomenda a infusão de um grande volume de fluidos na fase inicial de tratamento, enquanto outros autores recomendam a administração somente quando do controle da hemorragia. O acesso venoso femoral é contra indicado em pacientes com trauma abdominal por temor de aumento de hemorragia. A solução hipertônica de NaCl a 7,5% (SH) possui benefícios consideráveis de logística e de recuperação hemodinâmica com pequenos volumes de infusão, semelhante as vantagens das soluções padrões isotônicas na fase pré-hospitalar. Objetivos: Criar um modelo de choque hemorrágico induzido por trauma venoso. Avaliar a hemodinâmica e o volume de hemorragia abdominal nos animais submetidos a choque hemorrágico e tratados com SH via acesso femoral e jugular. Métodos: Em 18 porcos da raça landrace, divididos em 3 grupos de 6 animais (Controle, Jugular e Femoral), foi induzido um choque hipovolêmico não controlado pela ruptura da veia cava caudal. Os animais do grupo controle (GC) foram observados por 40 minutos quanto ao seu padrão hemodinâmico de Pressão de Artéria Pulmonar (PAP), Pressão Artérial Média (PAM), Débito Cardíaco (DC) e Fluxo de Veia Porta (FVP), porém sem reposição volêmica. Os animais dos grupos Femoral (GC) e Jugular (GJ) foram tratados com 4 ml/Kg de solução hipertônica de NaCl a 7,5% (SH) aos 20 minutos de experimento. Ao final do experimento, o volume de hemorragia abdominal foi mensurado.Resultados: O grupo controle (GC) apresentou queda dos valores hemodinâmicos aos 10 minutos e estes permaneceram estáveis até o final do experimento. Os animais dos grupos tratamento (GF e GJ) apresentaram melhora da hemodinâmica aos 30 minutos, sem aumento da hemorragia abdominal. Conclusão: A solução hipertônica de NaCl (SH) permitiu a melhora parcial da hemodinâmica no modelo de choque hipovolêmico, sem aumento da hemorragia, independentemente do acesso utilizada para a infusão.
Introduction: Volemic replacement in traumatized patients is controversial. The A.T.L.S. recommends the infusion of a great volume of fluids in the initial phase of the treatment, while other authors recommend the administration only when the hemorrhage is controlled. Venous femoral access is not indicated in patients with abdominal trauma because of fear of increasing hemorrhage. A 7.5% NaCl hypertonic solution (HS) has considerable logistic and hemodynamic recovery benefits with small volumes of infusion, similar to the advantages of standard isotonic solutions in the pre-hospital phase. Objectives: To create a hemorrhagic shock model induced by venous trauma. To evaluate the hemodynamic and the abdominal hemorrhage volume in the animals submitted to hemorrhagic shock and treated with HS via femoral and jugular access. Methods: In 18 Landrace pigs, divided in 3 groups with 6 animals each (Control, Jugular and Femoral), a non-controlled hypovolemic shock was induced by the rupture of caudal vena cava. The control group (CG) animals were observed during 40 minutes in relation to their hemodynamic pattern of Pulmonary Artery Pressure (PAP), Mean Artery Pressure (MAP), Cardiac Debt (CD) and Portal Vein Flux (PVF), but without volemic replacement. The femoral (FG) and Jugular (JG) groups were treated with 4ml/Kg of 7.5% NaCl (HS) hypertonic solution after twenty minutes of experiment. At the end of the experiment, the abdominal hemorrhage volume was measured. Results: The control group (CG) presented a decrease of the hemodynamic values after 10 minutes and they remained stable up to the end of the experiment. Animals from treatment groups (FG and JG) presented hemodynamic improvement after 30 minutes, without increase of abdominal hemorrhage. Conclusion: Hypertonic NaCl (HS) solution allowed a partial hemodynamic improvement in the hypovolemic shock model, without hemorrhage increase, independent of the access used for the infusion.

The caudal vena cava (CVC) is a highly compliant vessel. As central venous pressure rises, the CVC dilates because the failing right atrium can not accommodate the systemic venous return. Although radiographic evaluation of CVC size in dogs has been reported, certain limitations restrict its clinical application. The aim of this study was to establish fundamental ultrasonographic imaging data of CVC diameter in dogs and to compare CVC diameters between normal group (n=51) and right heart failure group (n=20) classed from II to IV according to New York Heart Failure Association (NYHA). These dogs were examined by two-dimensional ultrasound using a 5.0-MHz sector transducer. A right intercostal approach at eleventh intercostal space were used to obtain clear images of CVC and aorta at the level of the porta hepatis in the same plan. The luminal diameter of CVC was measured concurrently with peak diastolic (AOd) and peak systolic (AOs) aorta diameters respectively at quiet expiration. In normal dogs, the mean of CVC diameter measured with AOd was 8.71 ± 0.37 mm and the mean of CVC/AOd ratio (CVCd/AOd) was 1.08 ± 0.01, whereas the mean of CVC diameter measured with AOs was 8.87 ± 0.37 and the mean of CVC/AOs ratio (CVCs/AOs) was 1.19 ± 0.01. Body weight significantly affected CVCd and CVCs, but had little influence on CVCd/AOd and CVCs/AOs. The CVCd and CVCs showed no significant difference between normal and all NYHA heart failure groups. The CVCd/AOd and CVCs/AOs were getting higher with the severity of heart failure and there were significant difference between this three group and normal except the NYHA II. Adding it up, measurement of CVC/AO ratio is able to differentiate severity right heart failure from normal and mild right heart failure, and this ratio is more reliable than the CVC diameters.

The right heart is important to maintain hemodynamic stability through the pulmonary circulation, but its anatomically complex characteristic is difficult to describe by a simple geometric figure. Two-dimensional (B-mode) ultrasonographic detection of human inferior vena cava (IVC) has been widely used for assessing hydration status and diagnosing congestive right heart failure. However, the phasic blood flow from IVC to right atrium will influence the diameter of IVC. M-mode ultrasonography shows the time-motion characteristics of IVC, and identifies its physiologic size and pulsation. The aims of this study were to measure the diameter of caudal vena cava (dCVC) by B-mode and M-mode ultrasonography, and to evaluate its association with right heart function. The study population consisted of 26 Malteses, 12 Golden Retrievers, and 11 Labrador Retrievers aging from 1-6 years. The result showed that the dCVC was significantly different between Malteses (4.98 ± 0.72 mm) and Retrievers (11.75 ± 1.30 mm) (p < 0.05), and was highly correlated with body weight (r2 > 0.87). The CVC/aorta diameter ratio was irrelevant to body weight and to the breed (p > 0.05). The dCVC measured by B-mode and M-mode ultrasonography was highly correlated (r2 = 0.98), but the differences of M-mode dCVC were slightly more than B-mode (p > 0.05). The stroke volume (SV) and cardiac output (CO) of the right ventricle (RV) were correlated with dCVC (r2 = 0.45 vs. r2 = 0.52, p < 0.05). The dCVC of the dogs with right heart regurgitation (RH-R) were slightly larger than the dogs without RH-R (p > 0.05). Conclusively, CVC/aorta ratio seems to be independent from body weight, and the ratio could be used more conveniently in clinical examination. M-mode dCVC could be predictive for B-mode ultrasonography, however, the M-mode ultrasonography could even provide the exact assessment in clinical setting. Even though dCVC might not be a sensitive assessment of right heart function, it could still be applied to detect the RH-R and evaluate the RVSV and RVCO. Hence, dCVC measurement can be used alternatively for evaluating right heart function.
