“…These findings are consistent with results from studies in dogs that also measured BP using the Surgivet multivariable monitor (Deflandre & Hellebrekers ; Drynan & Raisis ), but contrast with previous studies in horses (Bailey et al. ; Hatz et al. ) – this disagreement could, however, be a result of differences in methodology, statistical assessment and machines used.…”

“…Studies in foals showed good agreement between mean arterial pressure (MAP) and diastolic arterial pressure (DAP), but poorer agreement for systolic arterial pressure (SAP) with a trend for the NIBP to underestimate the IBP (Branson 1997;Nout et al 2002;Giguere et al 2005). In contrast, two studies in adult horses both found that NIBP was a useful alternative to IBP measurement (Bailey et al 1994;Hatz et al 2015). However, the interpretation and application of results of previous studies are limited by the fact that these studies use different equipment.…”

“…Advantages and disadvantages of non-invasive blood pressure measurements have frequently been discussed in the scientific literature (Riebold and Evans 1985). Bailey et al found a large measurement error using indirect Doppler ultrasonic measurements in dorsally recumbent horses when compared to invasive systolic measurements (Bailey et al 1994). Other techniques (auscultatory technique, use of an aneroid manometer and electronic sphygmomanometer, Doppler arterial blood pressure etc.)…”

Summary: The purpose of this study was to assess the performance of indirect blood pressure measurements with an oscillometric blood pressure monitor (S/5, Datex-Ohmeda) in anaesthetized horses. The study was conducted as a prospective experimental study. Seven adult horses, five geldings and two mares, were used in this study. The average age was 15 ± 8 years (mean ± SD) and the horses were weighing between 485 and 654 kg. Invasive and non-invasive blood pressure measurements were recorded simultaneously and a total of 263 values were analyzed. The number of measurements obtained in each horse depended on the anaesthesia time (104 -225 minutes). Bland and Altman analysis for repeated measurements was used for assessment of the data. Overall the most accurate measurement was achieved with mean arterial pressure (MAP) measurement with a bias of 5 mmHg compared to a bias of 7 mmHg in the systolic arterial pressure (SAP) and of 9 mmHg in the diastolic arterial pressure (DAP). The MAP proved to be the most precise in the low arterial blood pressure group (3 mmHg) followed by the medium arterial blood pressure group (5mmHg). These results show that non-invasive blood pressure measurements with Datex Ohmeda (S/5, Datex-Ohmeda, S/5™ Collect, Datex-Ohmeda) monitoring can be an adequate alternative to measure blood pressure in anaesthetized horses when invasive blood pressure measurement cannot be performed. Besides monitoring of anaesthesia, non-invasive blood pressure measurement can be very helpful in alert horses due to its non-stressful and non-invasive nature. Further comparable projects are required in awake patients and data collected in this study could serve as a basis for that.Keywords: horse, anaesthesia, blood pressure measurement, oscillometric blood pressure monitor, Datex Ohmeda Citation: Fouché N., Auer U., Iff I.

“…In mature Thoroughbreds this value corresponded to a bladder width of 10.4 cm. Measurements of systolic arterial pressure in horses anaesthetised in dorsal recumbency with halothane using a cuff bladder to tail circumference ratio of 0.41 had an error range of * 20 mmHg in 5% of the horses (Bailey et al 1994).…”
