Resting energy expenditure in critically ill children on mechanical ventilation / 中华临床营养杂志

ABSTRACT

ObjectiveTo assess the energy expenditure status in critically ill children on mechanical ventilation.MethodsFifty critically ill children on mechanical ventilation were enrolled in this study.Resting energy expenditure (REE) on days 1,3,5,and 7 were measured.The predictive REE was calculated for each subject using age-appropriate equations (Schofield-HTWT).ResultsREE on day 1 and Schofield-HTWT equation predictive REE were (96.80 ± 42.63 ) and ( 110.67 ± 38.35 ) kJ/d,respectively.REE on days 1,3,5,and 7 were (100.53 ±50.24),(113.80 ±49.19),(117.99 ±50.57),and (115.05±50.18) kJ/d,respectively (F =1.267,P =0.292).The REE of day 1 in children with congenital heart disease (CHD) and without CHD was (75.66 ± 31.23 ) and ( 113.40 ± 28.40) kJ/d,respectively ( F =10.423,P =0.002).ConclusionsThe hypometabolic response is apparent in critically ill children with mechanical ventilation,and the energy expenditure shows no time-specific change within the first week.The energy expenditure in children with CHD is lower than those without CHD.
