Short-term Efficacy and Safety of Early Use of Different Doses of Amino Acid for Nutrition Support in Prema-ture Babies / 中国药房

ABSTRACT

OBJECTIVE:To explore short-term efficacy and safety of early use of high-dose,medium-dose and low-dose ami-no acid in premature babies. METHODS:99 premature babies were selected and randomly divided into high-dose group,medi-um-dose group and low-dose group,with 33 cases in each group. 3 groups were given Amino acid injection,ivgtt,within 24 h af-ter birth,high-dose group was given 3 g/(kg·d),medium-dose group 2 g/(kg·d)and low-dose group 1 g/(kg·d);those dose in-creased by 0.5 g/(kg·d)day by day;predicted peak values of them were 3.5,3.5 and 3 g/(kg·d),respectively. Treatment courses of 3 groups lasted for 28 d. Health indexes,renal function indexes and blood indexes were observed in 3 groups. The occurrence of complications and ADR were recorded in 3 groups. RESULTS:2 cases withdrew from high-dose and low-dose groups. Hospital-ization stay,the time of body weight increasing to 2 500 g and the rate of body weight decreasing in high-dose group were signifi-cantly lower or shorter than in medium-dose and low-dose groups;the medium-dose group was significantly lower or shorter than the low-dose group,with statistical significance (P<0.05);the levels of creatinine,residual alkali,serum total bilirubin in high-dose group were significantly higher than medium-dose and low-dose groups,and the medium-dose group was significantly higher than the low-dose group,with statistical significance(P<0.05). The number of complications cases in high-dose group(11 cases)were significantly lower than in medium-dose group(20 cases)and low-dose group(26 cases),with statistical significance (P<0.05). No obvious ADR was found in 3 groups. CONCLUSIONS:High-dose of amino acid intravenous nutrition support in early stage can promote the recovery of nutrition state and healthy constitution in premature babies with good tolerance and safety.
