“…Therefore, it is not applicable in clinical routine (HABERMAN et al, 2006), especially to evaluate horse athletes in the field. More recent study (DIAS et al, 2012) concluded that the implementation of facial catheter in horses is convenient and appropriate to evaluate animals exercising on a treadmill, unlike the present experiment that was performed in the field.…”

SUMMARYBlood pressure (BP) can be defined as blood pressure per surface unit of vascular wall, reflecting the interaction between cardiac output and peripheral vascular resistance. Systolic arterial pressure is the highest value on arteries, being associated with cardiac ventricular systole. Indirect blood pressure measurement is infrequently carried out in horses, but abnormal variations have been reported when colic, laminitis and epistaxis conditions occurs. A number of methods for indirectly measuring arterial blood pressure have been reported including invasive and non-invasive (oscillometric and ultrasonic-Doppler) techniques. The aim of this study was to evaluate the influence of physical exercise (gait) on values of systolic arterial pressure in horses. The study included ten adult Mangalarga Marchador horses (four males and six females) with mean weight of 426.60 ± 32.44 Kg and mean age of 6.7 ± 2.95 years old. Indirect measurements were obtained by oscillometric method in two different moments: rest (T0) and 5 minutes (T1) after the exercise. Comparisons between the different times were made using t-test at p<0.05 significance level. Uncorrected Coccygeal Values (CUCV) were 147±7 mmHg and 169±9 mmHg, respectively, at T0 and T1. The results showed that gait lead to significant increase of systolic arterial pressure (p<0.0001) and this occurred due to an increase of cardiac output during exercise. This clinical parameter could be used as a cardiac index for the evaluation of athletic horses. KEY-WORDS:Arterial pressure. Equine. Exercise.Marcha gait. RESUMOA pressão arterial (PA) é definida pela força exercida pelo sangue por unidade de superfície da parede vascular, refletindo a interação do débito cardíaco com a resistência periférica sistêmica. A pressão sistólica representa a mais alta pressão nas artérias, sendo associada com a sístole ventricular cardíaca. A aferição indireta da pressão arterial ainda é subutilizada na medicina equina, mas oscilações já foram descritas em casos de cólica, laminite e epistaxe. São diversas as formas de aferição usadas, destacando-se as técnicas invasivas e não invasivas (oscilométrica e guiada pelo uso do Doppler). O presente trabalho teve como objetivo avaliar a influência do exercício físico (marcha) sobre os valores registrados para pressão arterial sistólica em equinos. Foram avaliados 10 equinos da raça Mangalarga Marchador, com idade de 6,7 ± 2,95 anos e peso médio de 426,60 ± 32,44 Kg, sendo quatro machos e seis fêmeas. Procedeu-se avaliação indireta da PA por método oscilométrico em dois diferentes momentos: repouso (T0) e com 5 minutos (T1) após o término do exercício, representado por 40 minutos de marcha. Os resultados foram analisados através da comparação entre médias (teste-t), considerando o nível de significância de 5%. Foram registrados valores CUCV (valores coccígeos não corrigidos) de 147±7 mmHg e 169±9 mmHg, respectivamente nos momentos T0 e T1. A análise dos resultados demonstrou que a marcha influenciou de forma significativa os valores registra...

“…Although considered the "gold standard", the animal should preferably be sedated or under general anesthesia (SILVA, 2010;DIAS et al, 2012). Therefore, it is not applicable in clinical routine (HABERMAN et al, 2006), especially to evaluate horse athletes in the field.…”

“…The systolic arterial pressure (SAP), diastolic arterial pressure (DAP) and mean arterial pressure (MAP) were also measured (mmHg) during the three exercise tests. For this purpose, a 20-cm polyurethane catheter (Central Venous Catheterization set, ref CV-04701; Arrow International, Reading, PA) was implanted in the left facial artery [22]. The arterial line was flushed every 8 hours with a 10% ascorbic acid solution containing 5000 U of sodium heparin per mL [22] until the end of ET3, when it was removed.…”

a b s t r a c tThe purpose of the present investigation was to examine the effects of unilateral and bilateral jugular vein occlusion by temporary surgical ligature on the heart rate and arterial and venous blood pressure in sedentary horses during progressive treadmill exercise. Six horses performed three exercise tests (ET). ET1, considered the control, was performed in horses without jugular occlusions. ET2 and ET3 were performed with unilateral and bilateral occlusion by temporary surgical ligature of the jugular veins, respectively. Heart rate, arterial pressure, and pressure of the occluded jugular vein were evaluated. Clinically, the horses presented apathy, head edema, congested mucous membranes, increased capillary refill time, and dysphagia. These signs were observed with the unilateral jugular vein occlusion and became more evident with the bilateral occlusion. Comparing ETs, no differences were observed in heart rate. However, jugular occlusions promoted a decrease in the mean arterial pressure and a severe increase in jugular pressure. Head edema caused by the jugular vein occlusion in the horses could interfere with the autonomic cardiovascular regulation of arterial blood pressure during exercise, likely leading to an impairment of tissue perfusion. Jugular occlusion, even unilateral, also causes severe head venous congestion, leading to venous hypertension that was aggravated by exercise, which could risk development of cerebral edema and neurological damage. The present results obtained from sedentary horses are preliminary data that lead us to suggest that sport horses presenting jugular occlusive thrombophlebitis, even unilateral, may be prevented from performing athletic activities.

The purpose of the present investigation was to examine the effects of unilateral and bilateral jugular vein occlusion via temporary surgical ligature on arterial blood gases in horses during treadmill exercise. Six horses performed three exercise tests (ETs). ET1, considered to be the control, was performed in horses without jugular occlusion. ET2 and ET3 were performed in horses with unilateral and bilateral occlusion via temporary surgical ligature of the jugular veins, respectively. The partial pressure of oxygen (PO 2 ) and partial pressure of carbon dioxide (PCO 2 ) were determined. The PO 2 showed decreased values during ET2 and ET3, suggesting that horses presenting acute jugular thrombophlebitis may have airflow limitations when exercising. Key words: Blood gases, equine, swan ganz, thrombophlebitis, upper airways ResumoO objetivo do presente trabalho foi avaliar os efeitos da oclusão da veia jugular por ligadura cirúrgica unilateral e bilateral sobre os gases do sangue arterial em equinos durante o exercício em esteira. Seis equinos realizaram três exercícios teste (ETs). ET1, considerado como controle, foi realizado por equinos sem oclusão jugular. ET2 e ET3 foram cumpridos por equinos apresentando oclusão da veia jugular por ligadura temporária unilateral e bilateral, respectivamente. A pressão parcial de oxigênio (PO 2 ) e a pressão parcial de dióxido de carbono (PCO 2 ) foram determinadas. A (PO 2 ) demonstrou diminuição em ET2 e ET3, sugerindo que equinos com tromboflebite jugular aguda podem apresentar limitação no fluxo de ar inspirado durante o exercício.
