目的:北関東初の小児病院として当院が開院して以来30年間の当科における超低出生体重児の生命予後の変化について検討した。
方法:1982年7月から2012年6月までに当科に生後24 時間未満で入院した超低出生体重児513 例を対象とした。1982年7月から1992年6月,1992年7月から2005年6月,2005年7月から2012 年6月に入院した症例をそれぞれ前期群,中期群,後期群とし,死亡退院例の割合の変化,死亡原因について検討した。
結果:超低出生体重児の死亡退院は前期群107例中41例(38.3%),中期群251 例中50 例(19.9%),後期群155 例中15 例(9.7%)で,その割合は経時的に有意に低下していた。死亡原因は循環障害と重症感染症がいずれの群でも上位3つのうち2つを占めていた。
結論:死亡退院例の割合は経時的に低下していたが,死亡原因では循環障害と重症感染症の割合がいずれの時期でも高く,循環管理と感染症対策の改善が必要である。 |

Objectives:To investigate changes in outocme in extremely low birth weight infants(ELBWIs)in the 30-year period
since our hospital opened in July1982.
Methods:We analyzed our department’s database and medical charts to investigate mortality rates and causes of
death in 513 ELBWIs who were admitted to our hospital within 24 hours after birth, from July 1982 to June 2012.
Results:For ELBWIs admitted from July 1982 to June 1992, July 1992 to June 2005, and July 2005 to June 2012,
mortality rates were 41/107(38.3%), 50/251(19.9%), and 15/155(9.7%), respectively. The percentages of deaths
resulting from circulatory disorder and severe infection were 26.8% and 22.0% in ELBWIs admitted from July 1982 to
June 1992;28.0% and 34.0% in those admitted from July 1992 to June 2005;and 33.3% and 26.7% in those admitted
from July 2005 to June 2012, respectively. Circulatoy disorder and severe infection were included in the three most
common causes of death in each peirod.
Conclusions:The mortality rate has decreased with time, and circulatory disorder and severe infection remained the
most common causes of death. Careful management of circulatory system and effective prevention and treatment of
severe infection are necessary to further reduce the mortality rate in ELBWIs. |
