Abstrakt: Objective: To determine the effect of a single intravenous (IV) fluid bolus on the hydration of an avian patient, using packed cell volume (PCV) and plasma total solids (TS) to estimate hydration.
Procedure: Ten birds were allocated randomly to one of three groups, and administered 30 mL/kg or 50 mL/kg intravenous fluid, or were part of a control group and did not receive IV fluid. Blood was collected before the IV fluid bolus was administered, and at 1 minute, 3 hours and 6 hours after administration of the fluid. Samples were used to determine PCV and TS and results were compared between groups and between the different time points.
Results: Administration of 30 mL/kg or 50 mL/kg compound sodium lactate solution caused a statistically significant decrease in PCV. Within 3 hours, the PCV was not significantly different to the initial value or to the PCV of control birds. Administration of 30 mL/kg compound sodium lactate solution did not result in a significant decrease in TS. However, administration of 50 mL/kg produced a significant decrease in TS, which was still significantly less than controls 6 hours after the fluid was administered.
Conclusion: These findings suggest that an intravenous bolus of fluid may be safely administered to an anaemic bird, since PCV is significantly decreased for less than 3 hours. Up to 50 mL/kg of fluid may be administered as an intravenous bolus to a bird, to produce significant haemodilution that persists for up to 6 hours.
