1 case report patient male, 83 years old. March 2008 Bleeding due to brainstem unconsciousness, long-term hospitalization. On May 25, 2012, invasive mechanical ventilation resulting in respiratory failure due to pulmonary infection was transferred to the intensive care unit. Intermittent hand-foot twitching and arrhythmia were observed during hospitalization. Laboratory tests, serum potassium 2.73 mmol / L, sodium 128.07mmol / L, chlorine 70.84mmol / L. Give potassium citrate solution, intravenous potassium, oral rehydration salt treatment, serum potassium 3.24 ~ 3.49mmol / L, serum sodium, chloride returned to normal. Check the blood calcium, blood magnesium, respectively 2.01 mmol / L and 0.66mmol / L. Arterial blood gas analysis showed that pH 7.62, partial pressure of carbon dioxide 35.0mmHg, oxygen partial pressure 52.0mmHg, residual alkali (BE) 15.0mmol / L, bicarbonate 36.0mmol / L, oxygen saturation 0.92, potassium 3.1mmol / Tip generation
