2013-8 years China's extremely premature infant existed survival rate is 78%, more than 50% of children have moderate neurological disorders at 2 years old.

Despite the improvement in recent decades, the mortality and sequelae risks of the extremely premature infants are still higher. Recent researchers investigated the survival rate, hospitalization rate, nursing demand, neurological development and function of the United States at the end of the year of 22-26 months.

The study was carried out in 19 medical centers, which is part of the new student study of the Children's Health and Human Development Institute of the National Children's Health and Human Development. Participants were born from January 1, 2013 to 10877 pregnancy born during December 31, 2018, completed follow-up assessments at 22-26 months, and born 2008-201 Comparison of newborn months. The main endpoint of research is the survival rate and the incidence of diseases, including necrotic intestine colitis, infection, intracranial hemorrhage, preterm-infant retinal lesions and pneumatic dysplasia. At 22-26 months, 12 health and functional results were evaluated, including neurological, cerebral palsy, vision, hearing, recycling, and needed equipment.

Total 10,877 infants participated in research, including 49.0% of baby infants, 78.3% of discharged survival (8495/10848), increased from 76.0% of 2008-201 (adjusted difference, 2.0%). The survival rate of pregnancy was 10.9% (60/549) in pregnant (60/549), and the survival rate of pregnancy in pregnancy was 94.0% (2267/2412). Pregnant pregnancy in pregnancy in pregnancy in pregnancy is 30.0% (60/200) in pregnant treatment, and 23 weeks of pregnancy is 55.8% (535/958). The smaller the birthplace of the birth, the higher the complications. Overall, 8.9% (890/9956) infants have necrotic small intestine colitis, 2.4% (238/9957) early infection, 19.9% ​​(1911/9610) evening infection, 14.3% (1386/9705) is serious The intracranial hemorrhage, 12.8% (1099/8585) have serious premature germline retinal lesions, 8.0% (666/8305) have a serious bronchial dysfunction. 2,930 pregnancy 22-26 weeks premature infants completed follow-up, 2566 were evaluated. Two years follow-up, 8.4% (214/2555) children have moderate to severe cerebral palsy, 1.5% (38/2555) bilateral blind, 2.5% (64/2527) need hearing aid or cochlear, 49.9% (1277/2561) ) Re-hospitalization, 15.4% (393/2560) requires moving auxiliary or other support devices. Among the 85.7% (1198/2458), 48.7% (1198/2458) did not or mild neurological disorder at follow-up, 29.3% (709/2419) had moderate neurological disorders, 21.2% (512/2419) It has severe neurological disorders.

In 2013. - 18 years, the early pregnancy of the US pregnancy was 78.3%, and the data was increased by 2% from 2008 to 2012. Among the 27 weeks of pregnancy, it is common in hospitalization and neurological disorders when they are 27 weeks of pregnancy.
