Abstract

Background: Anterior fontanelles (AFs) of healthy newborn infants vary widely in size, this being a function of race, geographical location, gender, birth weight, mode of delivery and gestation. Abnormal variations in AF size portend a serious pathology of the cranium or intracranial structures. The established reference value for normal AF size is, therefore, an essential diagnostic tool. This study was conducted to determine the mean AF size and factors that are associated with its variability among apparently healthy term neonates in Lokoja, North Central Nigeria.

Methods: AF size was measured in 200 healthy inborn term neonates between 24 and 48 h post-delivery using a modified version of Mattur's method. Other parameters measured were head circumference, birth weight and length. Relevant statistical methods were used for data analysis, and P < 0.05 at a confidence interval of 95% was considered statistically significant.

Results: Eighty-six (43%) of the babies were males, and the mean birth weight and gestation were 3.09 (0.37) kg and 38.8 (1.2) weeks, respectively. Majority (72%) were delivered spontaneously per vagina. The mean (± SD) AF size of the study neonates was 2.62 (0.72) cm (2.53 [0.61] cm in males and 2.69 [0.79] cm in females). Neither gender nor mode of delivery affected AF size significantly. There was no significant correlation between AF size and occipitofrontal circumference.

Conclusion: AF size for term babies in our hospital differs from AF sizes reported from other parts of the world, further reiterating the utility of local/regional neonatal AF reference values.

尼日利亚中北部明显健康的足月新生儿前方脑室大小的测定。
背景:健康新生儿的前囟门(AF)大小差异很大,这与种族、地理位置、性别、出生体重、分娩方式和孕期有关。囟门大小的异常变化预示着颅骨或颅内结构的严重病变。因此,正常房颤大小的既定参考值是一个重要的诊断工具。本研究旨在确定尼日利亚中北部洛科贾表面上健康的足月新生儿的平均房颤大小及其变化相关因素:方法:使用改良版的 Mattur 方法测量了 200 名健康足月新生儿在产后 24 至 48 小时内的 AF 值。其他测量参数包括头围、出生体重和身长。数据分析采用了相关的统计方法,在置信区间为 95% 的情况下,P < 0.05 被认为具有统计学意义:86名婴儿(43%)为男婴,平均出生体重和孕期分别为3.09(0.37)千克和38.8(1.2)周。大多数婴儿(72%)经阴道自然分娩。研究新生儿的平均(± SD)腹腔膈大小为 2.62 (0.72) 厘米(男性为 2.53 [0.61] 厘米,女性为 2.69 [0.79] 厘米)。性别和分娩方式对房颤大小的影响均不明显。心房颤动大小与枕额周长之间没有明显的相关性:结论:我院足月儿的房颤大小与世界其他地区报道的房颤大小不同,这进一步重申了本地/地区新生儿房颤参考值的实用性。
