Measurement of serum lactate values in domestic cats (<i>Felis catus</i>) submitted to physical and chemical restraint

2017

The use of serum lactate has become increasingly common in Veterinary Medicine, since it is an excellent marker of tissue oxygenation, elevated in situations of tissue hypoxia, where anaerobic glycolysis is used as an energy source. Studies point out its use in dogs as a prognostic factor in several affections; however it is not commonly used in domestic felines due to the high stress threshold of the species, which may interfere with their values. The aim of the present study was to evaluate serum lactate values in domestic cats during physical restraint and after chemical restraint using the combination of 8mg/kg ketamine-S, 0.4 mg/kg midazolam, and 2 mg/kg Tramadol. To this end, 20 clinically healthy female cats without defined race, from six months to five years of age, were divided into two groups, GPR (n = 10) represented by felines that had only physical restraint and the GCR (n = 10) by felines that underwent physical restraint (TPR) and after 30 hours by chemical restraint (TCR). It was observed that in both groups (GPR and CPR) during physical restraint presented hyperlactatemia (GPR = 6.23 ± 0.9 mmol/L – GCR – Tpr = 6.66 ± 1.59 mmol/L) and mean values of 4.42 ± 1.28 mmol/L during chemical restraint (GCR – Tcr). It was concluded that physical restraint interferes with serum lactate values, with the reduction of such values with the use of chemical restraint in the feline species.
