Determination of food intake and the factors affecting food intake in perioperative period in patients who undergo open heart surgery

Abstract

Background: This study aims to investigate the factors affecting food intake in perioperative period of patients who undergo open heart surgery and the effects of body weight, albumin and hemoglobin values, nausea, vomiting and constipation on food intake.

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.
