The aim of this study was to evaluate the energy deficit one week after patients undergoing coronary artery bypass graft surgery. The nutritional status of these patients was also evaluated following the hospitalization at three time points: admission, before discharge, and 2-4 weeks after hospital discharge. The sample consists of 43 participants who were scheduled for an elective coronary artery bypass graft surgery from April to September 2010 at a 2200-bed unban medical center. All participants’ resting energy expenditures were measured once by Indirect Calorimetry within 24 hours after surgery. The obtained resting energy expenditure times 1.2 was then defined as recommended energy requirement. Participants were closely monitored on their actual calorie intake through 7-day daily intake food record to calculate the energy deficit. A structured nutrition assessment including anthropometrics and a Mini-Nutritional Assessment Questionnaire was conducted three times following hospitalization. Data revealed that energy deficit between recommended and actual intake were -1847.3±465.5 kcal on surgical day. On day 7, this deficit was -712.3±530.4 kcal. The accumulated mean deficit within 7 days was 7713.6±3100.5 kcal. The energy intake failed to exceed 75% of daily requirement on all 7 days for 53.3% of the sample. The average daily energy intake failed to 50% of daily requirement on all 7 days for 21% of the sample. Weight change was significant with 97% participants experienced weight loss and lost on average of 2.73±2.30 Kg by discharge. Most nutrition parameters declined 2-4 weeks following hospitalization. The result suggests that energy deficit and weight loss was common among patients undergoing coronary artery bypass graft surgery.973394 bytesapplication/pdfen-US冠狀動脈手術營養差距營養評估體重改變Coronary Artery Bypass Graft SurgeryEnergy DeficitNutrition SurveyWeight Lossthesishttp://ntur.lib.ntu.edu.tw/bitstream/246246/257881/1/ntu-100-R96426003-1.pdf
