宫内生长迟缓(IUGR)或称胎儿生长迟缓(FGR)是胎儿生长发育和围产期保健的主要问题之一。已知 IUGR 与先天畸形密切相关。IUGR 婴儿围产期死亡率为围产期总死亡率的三倍,幸存者多出现神经及智力缺陷。但在出生以前诊断 IUGR,至今仍是一个难题。仅根据出生体重来判断 IUGR 是沿用多年的传统方法,一般以出生体重不足2,500g或出生体重在同胎龄儿正常体重的第3或第10百分位数以下者作为本病诊断标准,常用低出生体重宫内发育迟缓(LBW-IUGR)
Intrauterine growth retardation (IUGR) or FGR is one of the major problems in fetal growth and perinatal care. It is known that IUGR is closely related to congenital malformations. The perinatal mortality rate in IUGR infants is three times of the total perinatal mortality rate, with more neurological and mental retardation in survivors. However, the diagnosis of IUGR before birth is still a problem. Only based on birth weight to determine IUGR is the traditional method of many years of follow-up, usually less than 2,500 g birth weight or birth weight in the normal third or tenth percentile of the normal weight of the third percentile as the diagnostic criteria of this disease, commonly used Low birth weight Intrauterine growth retardation (LBW-IUGR)
