Point-of-care blood gas and electrolyte analysis in rabbits.

This article outlines a practical approach for the use of blood-gas analysis in pet rabbits using the I-STAT analyzer. Sampling techniques and a theoretic approach to diagnosis are described. The following 95% RI were obtained from venous samples of 45 healthy rabbits: pH (7.245-7.533), PCO(2) (28.9-52.9 mm Hg), HCO(3) (17.0-32.5 mmol/L), total CO(2) (18-34 mmol/L), BE(ecf) (-10-8 mmol/L), AnGap (11-26 mmol/L), Na (136-147 mmol/L), K (3.4-5.7 mmol/L), Cl (93-113 mmol/L), Glu (93-245 mg/dL), BUN (9-33 mg/dL). Results from 20 arterial samples were pH (7.358-7.502), PCO(2) (29.1-36.8 mm Hg), HCO(3) (17.5-27.6 mmol/L), BE(ecf) (-7-5 mmol/L), PO(2) (75-101 mm Hg), iCa (1.67-1.85). The article also includes some conclusions obtained comparing results from healthy and ill rabbits over an 18-month period.
