0531. Cumulative effects of negative energy balance on myocardial deformity and diastolic function during the first week of ICU: a pilot study
2014
Methods We made an observational, analytical, prospective, longitudinal pilot study. Dependents variables: LS, echocardiographic parameter used to assess myocardial deformity (contraction). We considered as an improvement an increase ≥10%. E/e ratio, parameter used to assess DF. A reduction of E/e ratio ≥10% was considered DF improvement. I. V,: NEB during the first week of admision. Improvement in the NS: assessed by an increase in at least one level of prealbumin nutritional scale (PNS) after 10 days of receiving 100% of estimated energy (EE) requirements (H. Benedict). (PNS: Normal>18 md/dl, mild undernutrition: 17.9-15, moderate: 14.9-10 severe 100 Hz, for further analysis “of line” of LS. (Blind analysis). Exclusion crit.: nephrotic syndrome, cirrhosis, chronic renal and HF. PCR, MV (PEEP), PVC were recorded.
