First blood gas on 100% oxygen after reintubation and arterial line insertion demonstrated hyponatraemia: pO2 = 184mmHg, pCO2 = 54mmHgm, Na = 126mmol/L, K = 3.8 mmol/L, and HCO3 = 21 mmol/L.
Paraclinical investigations revealed mild hyponatraemia (Na: 133 mmol/L; normal: 135-145), with normal leukocyte count (WBC: 7.9 x [10.sup.12] cells/l; normal: 4.0-10.0 x [10.sup.12] cells/l), and moderately elevated C-reactive protein (CRP: 37 mg/l; normal: 0-3.3 mg/l); haemoglobin and haematocrit were within the normal ranges.
