Preoperative Investigation of Malnutrition in Elective Surgery Cases and Relationship with Serum Magnesium Level

Abstract

Presence of hypomagnesemia in the perioperative period can significantly increase morbidity (1). Preoperative nutritional deficiency may accompany magnesium deficiency. The aim of this study is; To investigate malnutrition by mini nutritional assessment-short form (MNA-sf) in patients scheduled for elective surgery and to examine the relationship between magnesium level, age, gender, surgical departments, BMI and ASA classification. Patients over the age of 18 who were scheduled for elective surgery were included in the study. The study was conducted with 387 patients according to statistical power analysis. In our study, magnesium level was found to be significantly lower in inverse proportion to age only in preoperative patients hospitalized in the general surgery department. It was found that the magnesium level of preoperative male patients hospitalized in the general surgery department was significantly higher than that of female patients. It was determined that the mini nutritional screening and evaluation tests showed statistically significant correlation in all surgical departments. Malnutrition is thought to have adverse effects on morbidity in the perioperative period. It may be very useful to detect malnutrition that can be detected by hypomagnesemia with a simple test beforehand.
