위절제술 후 빈혈에 있어서 Iron Sucrose의 효과

Abstract

Purpose: Many patients suffer with anemia after gastrectomy. Iron deficiency due to a decreased oral intake and malabsoption is the most common cause of anemia in gastrectomized patients. This study evaluated the efficacy of administering intravenous iron sucrose for treating patients with anemia. Materials and Methods: From May 2007 to October 2007 at Yonsei University Severance Hospital, we reviewed 47 outpatients whose hemoglobin levels were below 11 g/dl after gastrectomy. Iron sucrose was used for iron supplementation. To determine the difference between before and after the treatment (at 1 week, 2 weeks, 3 weeks, 3 months and 6 months after treatment), we prospectively examined such anemia parameters as the hemoglobin level (Hgb), the hematocrit (Hct), serum iron, TIBC, ferritin and transferin. Results: Out of the 47 patients, only 36 completed their treatment. Eleven were male and 25 were female. The Hgb levels, which indicate anemia, were elevated 0.6, 0.8, 1.3, 2.1 and 2.2 g/dl after 1 week, 2 weeks, 3 weeks, 3 months and 6 months after administration, respectively (P<0.001). The changes from 1 week to 3 months were statistically significant, but those from 3 to 6 months were not. The Hgb levels of 26 patients, which accounted for 72% of all the patients, elevated up to 12 g/dl or more. No side effects or complications were found, but there was one case of temporary nausea. Conclusion: Anemia after gastrectomy is safely treated in a relatively short time with administering iron sucrose. The patients' Hgb levels are expected to increase in a week and keep increasing up to 3 months
