1977年世界卫生组织建议,出生体重小于1,000g、胎龄小于28周的新生儿,称“超未熟儿”。由于新生儿医学的进展,超未熟儿成活率逐渐提高,死亡率已由本世纪六十年代的89.4%下降到八十年代的55.2%,甚至过去认为不能成活的500g超未熟儿也能成活。但预后并不乐观,且出生率及住院数有逐年增加趋势,超未熟儿出生数占低出生体重儿的23.1%。因此,有关超未熟儿的理论及临床已引起广泛重视。国内缺少此专题系统资料,现将国外资料加以综述,以供
In 1977, the World Health Organization suggested that newborns weighing less than 1,000g and gestational age less than 28 weeks should be referred to as “super-infants.” Due to the progress of neonatal medicine, the immature infant’s survival rate has gradually increased. The mortality rate has dropped from 89.4% in the 1960s to 55.2% in the 1980s. Even the 500-year-old infant who used to be considered alive can survive. But the prognosis is not optimistic, and the birth rate and number of hospitalizations have increased year by year, the number of ultra-immature births accounted for 23.1% of low birth weight children. Therefore, the theory and clinical aspects of ultra-immature children have drawn wide attention. The lack of systematic information on this topic in China is now available for review by foreign sources
