“…18 -21 A better method is therefore needed to guide fluid therapy during anesthesia. 22 Assessment of preload through monitoring of pulse pressure variation, total end-diastolic volume, and CO or repeated cardiac echocardiogram can serve as better guides to fluid therapy but are still not commonly used in clinical cases. 21 -24 In most severe thoracic and abdominal trauma patients, anesthesia can be achieved with the use of an opioid and benzodiazepine (opioid induction) administered intravenously.…”

“…A number of non-invasive methods of assessing CO have been studied in horses in the past, with transesophageal or transthoracic Doppler echocardiography ( 4 , 5 ), Lithium dilution techniques with and without pulse contour analysis ( 6 , 7 ), and carbon dioxide breath analysis currently available ( 8 , 9 ). In human medicine thoracic bioimpedance was one of the first and currently most widely used non-invasive method for CO monitoring due to its easy application and non-invasiveness ( 10 , 11 ).…”

Bioreactance is the continuous analysis of transthoracic voltage variation in response to an applied high frequency transthoracic current and was recently introduced for non-invasive cardiac output measurement (NICOM). We evaluated NICOM compared to thermodilution (TD) in adult horses. Six healthy horses were used for this prospective, blinded, experimental study. Cardiac output (CO) measurements were performed simultaneously using TD and the bioreactance method. Different cardiac output scenarios were established using xylazine (0.5 mg/kg IV) and dobutamine (1.5–3 mcg/kg/min). Statistical analysis was performed by calculating the concordance rate, performing a regression analysis, Pearson correlation, and Bland Altman. The TD-based CO and NICOM values were highly correlated for low, normal and high CO values with an overall correlation coefficient. A 4-quadrant plot showed an 89% rate of concordance. The linear regression calculated a relationship between NICOM and TDCO of Y = 0.4874 · X + 0.5936. For the corrected Bland Altman agreement, the mean bias and lower/upper limits of agreement were −0.26 and −3.88 to 3.41 L/min, respectively. Compared to TD, bioreactance- based NICOM showed good accuracy at induced low, normal, and high CO states in normal horses. Future studies performed under more clinical conditions will show if this monitor can help to assess hemodynamic status and guide therapy in horses in ICU settings and under general anesthesia.

“…These blood volume indicators might be useful to estimate changes in the volume status of a patient, or the location of preload on the Frank‐Starling curve. These variables were examined previously, using a different pediatric large animal model . To our knowledge, these blood volume indicators derived by the transpulmonary ultrasound velocity method have not been evaluated systematically during hemorrhage and fluid replacement in a neonatal animal model.…”
