[Variations in electrolytes in the smooth muscle tissue of the alimentary canal (author's transl)].

Electrolytes in the smooth muscle tissue of the alimentary canal were measured and their behavior under various conditions were studied on the basis of values measured. The results are summarized as follows: 1. Organic changes due to edema and the like are more prominent in the region near the wound in cases of damaged intestine. Utmost care should therefore be exercised when surgical treatment including resection of the intestine is given. 2. Variations in electrolytes are slight in cases of mesenteric hematoma, and surgical treatment is not necessary. 3. Variations in electrolytes are rather prominent in cases of intestinal fistula, and full consideration should be given to the balance of electrolytes, particularly supplement of K. 4. In casees of intestinal anastomosis, the rate of variation is the highest near the site of anastomosis and on the third day after surgery. Therapeutically, therefore, attention should be given to prevention of complications such as incomplete suture. 5. In cases of intestinal obstruction, variations are more marked and rapid. It brings about a high degree of disequilibrium of intra-tissue electrolytes in the upper intestinal tract; hence the early and adequate treatments are needed.
