Effect of pre-operation intestinal preparation by orally taking magnesium sulfate of two different concentration / 中国实用护理杂志

ABSTRACT

Objective To explore the effect of pre-operation intestinal preparation by orally taking magnesium sulfate of different concentrations. Methods 50 patients were divided into the high-concentration group and the low - concentration group, according to the concentration of magnesium sulfate orally taken for pre-operation intestinal preparation. Some factors were compared between the two groups including the acting amount of water, starting and lasting timing of magnesium sulfate, times of stool, the efficiency of the intestinal preparation, the tolerance, uncomfortable reaction and changes of serum electrolyte of the patients. Results There were no difference between the two groups on the acting amount of water, starting and lasting timing of magnesium sulfate, times of stool, the efficiency of the intestinal preparation, the tolerance of the patients. The rate of the stool without solid substance was higher in the high-concentration group than the low-concentration group(40% vs 8%). The uncomfortable reaction rate was also higher in the high-concentration group, the concentration of serum electrolyte decreased in both groups, among which serum Ca2+ decreased significantly in the low-concentration group. Conclusions Orally taking magnesium sulfate of different concentrations both has effect on bowel preparation, influence on patients' serum electrolyte is remarkable.
