Abstract
in English, French

This study assessed the accuracy of the oscillometric method for arterial blood pressure (ABP) monitoring in anesthetized camelids. Twenty camelids were anesthetized and systolic ABP (SABP), mean ABP (MABP), and diastolic ABP (DABP) were measured directly and using the oscillometric method. The mean difference between SABP measurements was -9.9 ± 21.9 mmHg with a range of -76 to 54 mmHg, and the 95% limits of agreement (LOA) were -33 to 53 mmHg. The difference between DABP measurements was -1.8 ± 15.6 mmHg with a range of -81 to 36 mmHg, and the 95% LOA were -32 to 29 mmHg. The difference between MABP measurements was -2.9 ± 17.0 mmHg with a range of -81 to 36 mmHg, and the 95% LOA were -30 to 36 mmHg. Accurate ABP monitoring in anesthetized camelids cannot be accomplished using the oscillometric method.

RésuméComparaison des techniques invasives et oscillométriques de mesure de la tension artérielle chez les camélidés anesthésiés. Cette étude évalue l’exactitude de la méthode oscillométrique pour la surveillance de la tension artérielle (TA) chez les camélidés anesthésiés. Vingt camélidés ont été anesthésiés et la TA systolique (TAS), la TA moyenne (TAM) et la TA diastolique (TAD) ont été mesurées directement et en utilisant la méthode oscillométrique. La différence moyenne entre les mesures TAS était de −9,9 ± 21,9 mmHg avec un écart de −76 à 54 mmHg et les limites de 95 % de concordance (LC) étaient de −33 à 53 mmHg. La différence entre les mesures TAD était de −1,8 ± 15,6 mmHg avec un écart de −81 à 36 mmHg et les LC de 95 % étaient de −32 à 29 mmHg. La différence entre les mesures de TAM était de −2,9 ± 17,0 mmHg avec un écart de −81 à 36 mmHg et la LC de 95 % étaient de −30 à 36 mmHg. Une surveillance exacte de la TA chez les camélidés ne peut pas être réalisée en utilisant la méthode oscillométrique.(Traduit par Isabelle Vallières).
