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.
