Clinical effect study of magensium sulfate on the intestine preparation before colonoscopy examination

Abstract

Objective We discussed the optimal method for intestinal preparation before colonoscopy examination in order to increase the success rate of intestinal examination and reduce the incidence of adverse effect. Methods We divided 120 patients who were to undergo colonoscopy examination into group A, B and C with 40 cases in each group. Group A received oral magensium sulfate 100ml and 6000ml water after that on the morning of the examination. Group B received oral magensium sulfate 50ml and 2000ml in the evening before the examination, oral magensium sulfate 50ml and 400ml water on the morning of the examination. Group C was given oral magensium sulfate 100ml and 4000～5000 water at the same time. Group A and B took part in appropriate activity and were given health education. The effect of intestinal preparation was compared between the three groups. Results The cleaning degree of group B was better than those of the other two groups (P<0.05). The adverse effect of group B was less than that of group C (P<0.01). Conclusions Oral intake of magensium sulfate in the evening before and on the morning of the examination for intestinal preparation could increase the cleaning degree of intestine, facilitate the observation of disease part and lessen adverse effect. It gave satisfying examination results and made patients satisfied. Key words: Magensium sulfate; Intestinal preparation; Colonoscopy
