This study examined risk factors for timing and cause of death for extremely preterm infants > or = 23 weeks and < 28 weeks. There were 479 liveborn infants and 98 deaths reviewed over a ten-year period. Thirty-two deaths (33%) occurred on the first day of life and 72 (75%) in the first month of life. Lower gestation and intrauterine growth restriction were significant risk factors for death. Most deaths occurred in the first month of life and at the lowest gestation in the first week.
本研究调查了孕周≥23周且<28周的极早产儿死亡时间和死因的风险因素。在十年期间，共审查了479例活产婴儿和98例死亡病例。32例死亡（33%）发生在出生第一天，72例（75%）发生在出生后第一个月。孕周较小和宫内生长受限是死亡的重要风险因素。大多数死亡发生在出生后第一个月以及出生后第一周孕周最小的时候。
