Use of lithium dilution and pulse contour analysis cardiac output determination in anaesthetized horses: a clinical evaluation

Comparison between lithium dilution and pulse contour analysis techniques for cardiac output measurement in isoflurane anaesthetized ponies: influence of different inotropic drugs

“…To the authors’ knowledge, there is only one report about the accuracy of the PulseCO software in horses (Hallowell & Corley 2005). These authors reported a mean difference between LiDCO and PulseCO of 0.2%, with limits of agreement of −10.6% to +11%, which was far better than the results of the present study.…”

“…(2006) did not report significant differences between LiDCO and PulseCO in anaesthetized dogs after epidural administration of romifidine, the difference between the two methods gradually increased over time. One study in 24 horses undergoing elective or colic surgery reported a good correlation between LiDCO and PulseCO (Hallowell & Corley 2005). As part of a larger study investigating the effects of different inotropic and/or vasoactive drugs (Schauvliege et al.…”

Influence of ketamine or xylazine supplementation on isoflurane anaesthetized horses- a controlled clinical trial

“…HR, respiratory rate (f R ), MAP and F e ′Iso were recorded every 10 minutes. The (L minute −1 ) was measured every 30 minutes by lithium dilution method using a commercial machine (LiDCO plus ; LiDCO Ltd.; UK) (Hallowell & Corley ) and cardiac index (CI) per kg bodyweight was calculated. Lithium chloride (2.250 mmol) was compounded by a local pharmacy (Löwen‐Apotheke; Germany).…”

Detomidine and the combination of detomidine and MK-467, a peripheral alpha-2 adrenoceptor antagonist, as premedication in horses anaesthetized with isoflurane

“…The samples were stored in iced water and analyses (ABL 800 basic; Radiometer Medical ApS, Denmark) were performed within 15 minutes after sampling. Cardiac output was measured at the same time points by means of the lithium dilution technique (LiDCO Plus Hemodynamic Monitor; LiDCO Ltd, UK), as previously described for horses (Hallowell & Corley ). Standard values of 10 g L −1 haemoglobin and 140 mmol L −1 of sodium were used and later corrected with measured values obtained from simultaneously drawn arterial blood samples.…”
