The analysis of hypocaloric nutrition in perioperative of patients with congenital hypertrophic pyloric stenosis / 重庆医学

ABSTRACT

Objective To analyze the hypocaloric nutrition(PN) in perioperative of patients with congenital hypertrophic pyloric stenosis ,and to provide reference basis for its clinical application .Methods 40 patients with congenital hypertrophic pyloric steno-sis were choseen in our hospital .All patients were divided into observation group and control group ,20 cases in each group .After the conventional support treatment ,patients in observation group were gave hypocaloric nutrition of 70 -90 kcal/kg ,patients in control group were gave hypercaloric nutrition of 100-200 kcal/kg .After 5 days ,nitrogen balance ,serum protein and body compo-sition were observed in the two groups .Results The nitrogen discharge was increased after parenteral nutrition ,after 2 days reached to peak ,and then began to decline slightly .Under the condition of the same nitrogen intake ,the nitrogen balance in observa-tion group was 10 .65 g/d ,which was significantly lower than 16 .40 g/d in control group (P0 .05) .After parenteral nutrition ,the total protein ,albumin ,prealbumin ,transferrin in observation group were (58 .22 ± 4 .63)g/L ,(43 .42 ± 3 .53)g/L ,(269 .65 ± 31 .24)g/L , (2 .83 ± 1 .23)g/L ,respectively ,which were higher than that in control group (42 .11 ± 3 .52)g/L ,(35 .57 ± 3 .82)g/L ,(252 .34 ± 27 .03)g/L ,(2 .20 ± 1 .30)g/L ,the differences were statistically significant (P0 .05) .Observation group had greater TBF and F% but decreased LBM versus control group (588 .7 ± 66 .8)g vs . (492 .8 ± 65 .6)g ,(17 .5 ± 1 .9)% vs .(15 .0 ± 1 .8)% ,(2 498 .5 ± 118 .9)g vs .(2 604 .7 ± 125 .4)g .The differences were statistical-ly significant(P<0 .05) .Conclusion Hypocaloric nutrition can meet the metabolic needs of patients with congenital hypertrophic pyloric stenosis .Hypocaloric nutrition play a positive role in improving nutritional status and can improve the postoperative rehabilitation .
