Institution where study was conducted: (1) Department of Clinical Nutrition, (2) Department of surgery, (3) Department of chest medicine, (4) Department of Nursing; China Medical University Hospital

Keywords: Respiratory Care Center, Prealbumin, Nutrition intervention, Hypocaloric

Background: In obese subjects, respiratory system mechanics can become disturbed, and that may prolong the days of mechanical ventilator used.

Objectives: To investigate the effect of a hypocaloric diet compared to an adequate calorie diet on the nutritional status and body weight change of patients in the respiratory care center.

Methods: A retrospective observational audit of 80 adult patients admitted to the China Medical University Hospital RCC between July 2016 and July 2017 was performed. Entry criteria included adult (18-65 years old) and elderly (>65 years old) patients who had ventilator use and required enteral tube feeding for at least 21 days. The primary measure was patients’ BMI. Patients were separated into three groups according to BMI: a normal weight group (N) (18.5–23.99 kg/m2,n=45)、overweight group (O) (24-26.99 kg/m2,n=20)and obese group(OB)(≥27 kg/m2,n=15). Other measures included gender, age, and admission specialty. Each group was separated into an adequate calorie diet (A) (25.39-27.24kcal/actual BW/day) and a hypocaloric diet (H) (6.71-24.66kcal/actual BW/day) randomly. Obese group only received hypocaloric diet . All groups received 1.2–2.2 g/kg IBW/day of protein.

Results: There were significantly elevated serum prealbumin levels in the OH group at 1st and 2nd weeks, whereas no significant differences in prealbumin levels were detected in the OA group. There was no statistically significant difference in levels between the two groups. The OH group have significant body-weight loss. (P=0.038)However, the differences in weight loss in OA group was not found to be statistically significant. In addition, OB group have significant body-weight loss was detected (P=0.003). The OA group seemed to have substantially longer days of mechanical ventilator used than the OH group. Nonetheless, the differences between the two groups was not found to be statistically significant. Compared with OH group,the OB group seemed to have substantially longer days of mechanical ventilator used,whereas no significant differences was detected.

Conclusion: Hypocaloric nutrition therapy offers an effect on body weight loss for respiratory failure patients with overweight and obesity. However, there is no statistically significant effect on the duration of mechanical ventilator used.
