To look at the survival pattern of extreme preterm Omani infants (23-26 weeks gestation) and compare it with the western countries.
All extreme preterm Omani infants (gestational age of 23 to 26 weeks) admitted from November 1991 to February 1998 at the Neonatal Intensive Care Unit of Sultan Qaboos University Hospital were reviewed. The detailed records of the infants, including name of mother, age, gravidity, parity, route of delivery, Apgar score, time of birth, inborn or outborn, birth weight, gestational age, sex, need for resuscitation, course in the Neonatal Intensive Care Unit, admission and discharge diagnosis, and outcome were collected from the register. The infants were stratified according to the gestational age and then analyzed for the survival rate among the different gestational ages.
A total of 32 extreme preterm infants were admitted to the Neonatal Intensive Care Unit of Sultan Qaboos University Hospital from November 1991 to February 1998. The mean birth weight of the cohort was noted to be 798+123 gram (Range 480-1015 grams). The mean gestational age was noted to be 25.5+0.95 weeks (Range 23-26 weeks). An equal number of males and females were noted in the cohort, with male to female ratio of 1:1. A total of 13 infants survived out of 32 infants. The overall survival rate for the cohort was noted to be 41%. For the present study, the western statistics are averaged and than compared with the Omani statistics. The survival rate for western 26 week preterm infants was (on average) 61% as compared to 44% among Omani preterm infants. The same trend of low survival was noted for 23 and 24 week Omani infants, except for only one 25 week infant.
The significant lower survival rate suggests the need for more attention and improvement in the management and care provided to the extreme preterm Omani infants.
观察阿曼极早早产儿（孕23 - 26周）的生存模式，并与西方国家进行比较。
回顾了1991年11月至1998年2月在苏丹卡布斯大学医院新生儿重症监护病房收治的所有阿曼极早早产儿（孕龄23至26周）。从登记册中收集了婴儿的详细记录，包括母亲姓名、年龄、孕次、产次、分娩方式、阿氏评分、出生时间、本地或外地出生、出生体重、孕龄、性别、复苏需求、在新生儿重症监护病房的病程、入院和出院诊断以及结局。根据孕龄对婴儿进行分层，然后分析不同孕龄的存活率。
1991年11月至1998年2月，共有32名极早早产儿入住苏丹卡布斯大学医院新生儿重症监护病房。该队列的平均出生体重为798 + 123克（范围480 - 1015克）。平均孕龄为25.5 + 0.95周（范围23 - 26周）。该队列中男性和女性数量相等，男女比例为1:1。32名婴儿中共有13名存活。该队列的总体存活率为41%。在本研究中，将西方统计数据进行平均后与阿曼的统计数据进行比较。西方26周早产儿的存活率（平均）为61%，而阿曼早产儿为44%。除了一名25周的婴儿外，23周和24周的阿曼婴儿也呈现出相同的低存活率趋势。
显著较低的存活率表明需要更加关注并改善为阿曼极早早产儿提供的管理和护理。
