To evaluate the maternal demographics, incidence, perinatal outcomes, and characteristics of babies born before arrival (BBAs) to hospitals.
A prospective, observational study was conducted at a large maternity unit in Durban, KwaZulu-Natal. A total of 200 mothers who attended the hospital within 24 hours of an out-of-hospital birth were recruited and interviewed, and 142 participants were eligible. A total of 128 mothers who delivered their babies in hospital (inborns) were used as the control group. Specific maternal and neonatal characteristics were analysed.
The incidence of BBAs was 2.2%. The percentage of premature neonates in the BBA group was 54% vs 17.9% for inborns ( ≤ 0.001). A total of 33.8% of BBA mothers were unbooked vs 2.4% of inborns ( ≤ 0.001). The majority (59%) of inborns were primigravidas whereas the majority (73.9%) in the BBA group were multigravidas ( ≤ 0.001). Women in the BBA group were more prone to genital tears ( ≤ 0.001). There were no significant differences in respect of NICU admission and all-cause mortality; however, an increased risk for hypothermia and hypoglycaemia was found.
BBAs are at a significant risk of prematurity, low birth weight, hypothermia, and hypoglycaemia and are prone to longer hospital stays.
评估产妇人口统计学特征、发生率、围产期结局以及在到达医院之前出生的婴儿（BBA）的特征。
在夸祖鲁 - 纳塔尔省德班的一个大型产科单位进行了一项前瞻性观察研究。共招募并访谈了200名在院外分娩后24小时内到医院就诊的母亲，其中142名参与者符合条件。将128名在医院分娩的母亲（院内出生儿）作为对照组。分析了具体的产妇和新生儿特征。
BBA的发生率为2.2%。BBA组早产儿的比例为54%，而院内出生儿组为17.9%（P≤0.001）。BBA母亲中未登记的比例为33.8%，而院内出生儿组为2.4%（P≤0.001）。大多数（59%）院内出生儿是初产妇，而BBA组大多数（73.9%）是经产妇（P≤0.001）。BBA组的女性更容易发生会阴撕裂（P≤0.001）。在新生儿重症监护病房（NICU）入院率和全因死亡率方面没有显著差异；然而，发现体温过低和低血糖的风险增加。
BBA有早产、低出生体重、体温过低和低血糖的显著风险，并且住院时间往往更长。
