Popis: Xylazine (XYL) and acepromazine (ACP) are known to decrease the hematocrit (HT) of horses when administered alone. However in routine anesthesia these drugs are administered by associations which ultimate effect in the HT is unknown but may cause false impressions about the hydration status, blood loss and red blood cell indices. The objective of this study was to characterize the values of HT in horses anesthetized with XYL, ACP, ketamine, midazolam, guaiphenesin, isoflurane and ephedrine. Twenty healthy horses were premedicated with either XYL 0.8 mg/kg (XYL group, n=10) or XYL 0.5 mg/kg plus ACP 0.05 mg/kg (XYL+ACP group, n=10). Anesthesia was induced with ketamine, midazolam and guaiphenesin and maintained with isoflurane. Ephedrine was infused for cardiovascular support. HT, vital parameters and blood gas values were evaluated at baseline, between each drug administration, after standing and 24 hours after baseline (24hBL). The HT started to decrease 17 and 40 minutes after premedication in XYL group and XYL+ACP group, respectively (p
