Objective To discuss the clinical effect of treatment on IUGR

and to find better treatment means.Method The IUGR patients were divided into treatment group and control group

and each group included 48 cases.The treatment group consisted of 24 cases of a combined therapy group（L-Amino-acid+amino acid）and 24 cases of a single amino acid group.Results There are significant differences between treatment group and contro1 group in birth weight and intrauterine hypoxia（P<0.05）

but there’s no obvious difference in neonatal asphyxia（P>0.05）.The increase value of fetal growth parameters（including biparietal diameter

femur length）of the combined treatment group is higher than the control group（P<0.05）.Conclusion The IUGR patient should be treated as early as possible

and a combined treatment group has greater advantages than a single amino acid group and control group.
