[Early parenteral nutrition in complex post-operative periods].

OBJECTIVE

The protein hypercatabolic state in critically ill pediatric patients can be minimized by an effective nutrition therapy. We conducted a study to evaluate the benefits of early parenteral nutrition (EPN) assessing its effect on nutritional parameters and clinical relevance after complex surgical procedures.

METHODS

Prospective randomized study in patients undergoing abdominal surgery in which nothing by mouth is anticipated for a period ≥ 3 days, between 2012 and 2014. Blood tests were performed assessing nutritional parameters in the first 24 hours and the 5th postoperative day. Two groups were created, starting EPN in group A and standard fluid therapy in group B, after the extraction of the first sample.

RESULTS

Forty-four patients were included, 18 in group A and 26 in group B. In the first analysis all had decreased levels of prealbumin and retinol-binding protein. On the 5th day, 55,6% of group A normalized prealbumin levels compared to 11,5% of B (p: 0.003, EF = 80%) whereas retinol-binding protein was normalized in 66,7% and 34.6%, respectively (p: 0,07, EF = 48,4%). Three patients in group A (16,7%) had postoperative infectious complications compared to 8 in B (30,8%), difference no statistically significant but clinically relevant (NNT=7,1), since the latter showed low prealbumin levels and longer hospital stay. No complications related to EPN were detected.

CONCLUSION

Administration of EPN in the complex postoperative patients appears to be safe and beneficial for their recovery, being the prealbumin an early indicator of good nutritional response.
