Abstract:
Objective To investigate the clinical significance of measuring resting energy expenditure (REE) for guiding an accurate nutritional support in elderly bedridden patients with nasal feeding.Methods The REE of 32 elderly bedridden patients with nasal feeding was assessed by using the Cosmed K4b2 portable telemetric gas analysis system.The waist-hip ratio, serum levels of albumin, transferrin, prealbumin and retinol-binding protein were determined to assess comprehensive nutrition status.The energy intakes were calculated, and the correlation of REE and the difference between the energy intakes and consumption with nutritional index were analyzed.Results The resting energy expendture was lower in the patients with waist-hip ratio≥0.95 than in patients with waist-hip ratio ＜0.95 (t=3.622, P＜0.01).The waist-hip ratio was reduced and serum albumin and transferrin levels were decreased along with the increase of REE in elderly patients (r=-0.55,-0.36 and-0.593, respectively, P=0.001, 0.043, ＜0.001).The difference between the energy intake and expenditure was higher in patients with waist-hip ratio≥0.95 than those with waist-hip ratio＜0.95 (t =5.643, P＜ 0.001).Serum albumin, prealbumin, transferrin and retinol-binding protein levels were increased along with the increase of the difference between the energy intake and expenditure, which showed the positive correlations (r=0.525, 0.409, 0.624, 0.414, respectively,P=0.002, 0.02, ＜0.001, 0.019).Conclusions Precise determination of REE and energy intake guided by REE are the important guarantees for the reasonable nutrition support in the elderly.
