我们采用柯氏测量法,对100例足月妊娠,阴道正常分娩的新生儿头径、身长、体重进行测量,探讨西安地区胎儿头径、身长、体重的参值.儿头各径线的平均值分别为:双顶径8.8厘米;双颞径7.4厘米;枕颏径12.8厘米,其周径33.8厘米;枕额径11.1厘米,其周径35.2厘米;枕下前额径10.3厘米,其周径33.1厘米;枕下前囟径9.0厘米,其周径31.6厘米;气管前囟径9.8厘米,其周径32.4厘米.身长平均为50.4厘米.体重平均为3195克.经统计学处理.新生儿身长、体重与儿头各径线呈一致的增减.因此,根据胎儿大小.可以大概估计分娩的难易程度.
We used Korschner’s method to measure the head diameter, body length and body weight of 100 newborns with full-term pregnancy and normal vaginal delivery to explore the fetal head diameter, body length and body weight in Xi’an area. Values were: biparietal diameter 8.8 cm; double temporal diameter 7.4 cm; pillow chin diameter 12.8 cm, the circumference 33.8 cm; pillow diameter 11.1 cm, the circumference of 35.2 cm; suboccipital forehead diameter 10.3 cm, the circumference 33.1 cm; occipital bregma diameter of 9.0 cm, the circumference of 31.6 cm; tracheal anterior bregax 9.8 cm, the circumference of 32.4 cm. The average length of 50.4 cm. The average weight of 3195 grams. Statistical analysis. , Body weight and the diameter of the child was consistent with the increase or decrease, therefore, according to the size of the fetus, you can probably estimate the ease of delivery.
