本文试图通过1980年10月至1983年3月于我院分娩的2180例(其中男婴1135例,女婴1045例)正常新生儿及胎盘完整者进行统计分析,以取得有关的生理正常数据,进而找出海拔在2260公尺的西宁地区新生儿胎盘某些特点以及产生原因等。新生儿双亲均为长年居住在上述高原地区的工人,干部及城市居民或近郊农民,通过对2180例正常胎盘重量进行统计分析,提出了本地区胎盘重量的有关正常值范围及探讨了男女婴胎盘重量的孕周分布与初经产及胎次的关系。探讨了胎盘重量与新生儿体重的比值以及相关关系并提出了体重与胎盘重量的直线回归方程。证明了高原胎盘重于平原胎盘的理论根据。
This article attempts to make statistical analysis of 2180 normal newborns and placenta intakes from 1180 women (1135 infants and 1045 infants) delivered in our hospital from October 1980 to March 1983 to obtain the relevant physiological data, And then find out the elevation of 2260 meters in Xining neonatal placenta some of the characteristics and causes. Neonatal parents are all workers, cadres and urban residents or suburban peasants living in the above plateau for many years. Based on the statistical analysis of the weight of 2180 normal placenta, the normal range of placental weight in this area is proposed and the relationship between male and female infants Relationship between gestational age distribution of placental weight and first trimester birth and parity. The ratio of placental weight to newborn weight and its relationship were also discussed and a linear regression equation of body weight and placental weight was proposed. The proof of the plateau placenta in plain placenta theory basis.
