In August 1995, 17 patients were mistakenly poisoned by using barium carbonate as food starch, all of whom were males, the oldest was 56 years old and the youngest was 8 years old, with an average of 30 years old. This group of patients were oral poisoning, 0.5 to 1 hour symptoms, nausea, vomiting, abdominal pain, diarrhea, numbness around the nose and mouth, limb symmetry of soft paralysis, chest tightness, suffocation, speech difficulties, tendon reflexes weakened or disappeared. 3 cases of severe poisoning In addition to the above symptoms worsening, respiratory muscle paralysis, respiratory arrest stopped. All cases without fever, coma and sensory disturbances. Laboratory tests: 17 cases of serum potassium was significantly lower, of which 9 cases in the 3 ~ 2mmol / L, 5 cases in 2 ~ 1.5mmol / L, 3 cases in 1.5mmol / L or less, serum sodium magnesium chloride, Vomitus and suspected food barium qualitative analysis of positive. This group of patients have varying degrees of ECG changes, the main changes are ST segment depression, T wave low flat, biphasic, inverted U wave appears, increased, U ≧ T, T wave biphasic, U upright, T wave inversion, TU Bimodal, fusion, there are 3 cases of severe premature ventricular contractions, ventricular tachycardia, ventricular fibrillation. In this group of patients were inserted stomach tube gastric lavage, sodium sulfate catharsis, detoxification (thio
