Fig. 1From: Blood acid-base status in impala (Aepyceros melampus) immobilised and maintained under total intravenous anaesthesia using two different drug protocols Box plot and whiskers of the independent variables in healthy impala (Aepyceros melampus) thought responsible for the change in hydrogen ion concentration (pH) in the plasma. Time 1 was sampling after immobilisation with either thiafentanil-medetomidine (P-TMP) or etorphine-medetomidine (P-EME). Time 2 was sampling at the end of either a propofol-ketamine-medetomidine (P-TMP) or an etorphine-ketamine-medetomidine (P-EME) total intravenous infusion. Where: PaCO2 is the arterial partial pressure of carbon dioxide; SIDa is the apparent strong ion difference; Atot is the total weak acid concentration in plasma; mmHg: millimetres mercury; mEq/L: milliequivence per litre and mmol/L: millimoles per litre; †: significant change in variable value over time for P-TMP protocol; ‡: significantBack to article page
