dc.description.abstract |
Blood lactate is a predictor of mortality in critically ill humans and animals. Handheld lactate
meters have the potential to be used in the field to evaluate the condition of severely injured
rhinoceroses but have not been compared with laboratory-based methods. Agreement between
a handheld lactate meter and a laboratory method was assessed, as was the stability of rhino
blood lactate in the anticoagulant sodium fluoride/potassium oxalate (fluoride/oxalate). Blood
samples were obtained from 53 white rhinos that had been immobilised for management
reasons. Lactate was measured by means of a handheld meter using whole blood in heparin
(WBHEP), whole blood in fluoride/oxalate (WBFO) and fluoride/oxalate plasma (PFO). Results
were recorded in both blood (BL) and plasma (PL) modes and compared to an established
laboratory method for measuring plasma lactate. To assess the stability of lactate over time,
blood lactate in fluoride/oxalate was measured on the handheld meter at intervals for up to
91 h. Agreement was best using WBFO in PL mode, with small bias (-0.16), tight 95% limits of
agreement (LOA) (-1.46, 1.14) and a Pc (95% CI) of 0.97 (0.92, 0.99). The agreement was improved
for all sample types when using the PL mode compared to the blood lactate (BL) mode. Blood
lactate was stable in fluoride/oxalate for 91 h, with a mean change from baseline of 0.15 (-0.178,
0.478) mmol/L (mean, 95% CI). The handheld meter was found to be suitable for field use in
white rhinos but provided more reliable results with the device in PL mode. Furthermore, rhino
blood lactate was found to be stable in fluoride/oxalate for as long as 3 days. |
