Koroner Bypass Ameliyatı Geçiren Hastalarda Beslenme Durumu ve Malnutrisyon Riskinin Saptanması
Abstract
The aim of this study
was to determine nutritional status and malnutrition risk among patients
undergoing coronary bypass surgery at preoperative and postoperative terms via
two different screening tools (Malnutrition Universal Screening Tool-MUST and
Nutritional Risk Screening-NRS-2002), dietary records, blood parameters, body
composition analysis (Bioelectrical Impedance Analysis-BIA). Percent body fat and
fat mass decreased (p<0.001); while lean body mass and total body water increased
at postoperative term compared to preoperative term (p<0.01). Energy intake,
carbohydrate, protein and fat percents decreased at postoperative term compared
to preoperative term (p<0.01). Serum albumin and total protein were negatively
associated with malnutrition risk (p<0.05). While malnutrition risk increased
according to MUST, BMI values decreased at preoperative and posterative (p<0.05).
According to postoperative NRS-2002, percent body fat was higher whereas lean
body mass was lower among patients at risk (p<0.01). Medium risk patients
consumed less protein than low risk patients according to preoperative MUST
assessment (p<0.05). Energy, carbohydrate, protein, fat intake, g/kg protein and
energy intake in percent according to daily recommendation were significantly
lower in patients under malnutrition risk according to NRS-2002 (p<0.01).
Malnutrition screenig tools as well as food consumption, body composition, blood
parameters should be taken into consideration in terms of determination of
malnutrition risk among patients undergoing coronary bypass surgery.
