For a 24-month period (1977 through 1978), the determinants of neonatal intensive care unit (NICU) mortality were examined retrospectively in 133 consecutively admitted newborn infants who weighed less than 1,000 g at birth. Seventy-one (53.4%) died during the first five days of life, 27 (20.3%) died after the first five days of life, and 35 (26.3%) were eventually discharged from the unit. Neonatal infection was the key determinant of increased mortality after the first five days of life. In these patients, gram-positive organisms were recovered from 54% (14/26) of all body fluid cultures from 21 infected infants. Infections included Staphylococcus epidermidis (27% [7/26]), Staphylococcus aureus (15% [4/26]), and Escherichia coli (11% [3/26]). We propose that reducing the incidence of neonatal infections is necessary to substantially improve late NICU mortality in these very-low-birth-weight neonates.
在1977年至1978年的24个月期间,对133例出生时体重不足1000克的连续入院新生儿进行了回顾性研究,以探讨新生儿重症监护病房(NICU)死亡率的决定因素。71例(53.4%)在出生后前五天内死亡,27例(20.3%)在出生后前五天后死亡,35例(26.3%)最终从该病房出院。新生儿感染是出生后前五天后死亡率增加的关键决定因素。在这些患者中,从21例感染婴儿的所有体液培养物中,54%(14/26)培养出革兰氏阳性菌。感染包括表皮葡萄球菌(27%[7/26])、金黄色葡萄球菌(15%[4/26])和大肠杆菌(11%[3/26])。我们认为,降低新生儿感染的发生率对于大幅提高这些极低出生体重新生儿在NICU后期的死亡率是必要的。
