Methods: This cross-sectional study was conducted between 4 February 2015 and 4 May 2015 in a cardiovascular surgery clinic. A questionnaire including 25 questions was applied to a total of 86 volunteer participants (62 males, 24 females; mean age 61.3±10.8 years; range 38 to 82 years).

Results: Patients consumed 38% of the food one day before the surgery and 51% one day after, 47% three days after, and 52% five days after the surgery. Factors affecting food intake were the procedure of discontinuing food intake for pre-surgery anesthesia preparation (84.9%), nausea (31.4%) one day after surgery, and constipation three (26.5%) and five (33.7%) days after surgery. Albumin levels decreased significantly in days after surgery compared to the day before surgery (p<0.05). There was a significant positive correlation between food intake rates and albumin levels on the first, third and fifth days after surgery (r=0.354, r=0.353, and r=0.521, respectively; p<0.05).

Conclusion: Patients’ body weight and albumin levels decreased in accordance with their nourishment status after surgery. Food intake was insufficient in the perioperative period.
