目的 测量足月新生儿指距,计算其正常范围值,探讨指距对新生儿生长发育评价的意义。方法 对762例足月新生儿(男397例、女365例,日龄1-3天),采用无弹性皮软尺测量指距,将新生儿仰卧在平板床上,双上肢拉直,与床面平行,测量两中指尖的距离,精确到1 mm。结果 新生儿指距男(50.75±1.69)cm,女(50.11±1.61)cm,平均为(50.13±1.65)cm,男女无显著性差异(P>0.05),P3-97为46.12-53.28 cm,指距与上肢长r=0.8962,P<0.01,与身长r=0.8871,P<0.01,均呈高度正相关。指距与身长相近,指距略大于身长,指距与身长之比为1/0.99,指距(cm)=身长(cm)×1.01,指距(cm)=上肢长(cm)×2+10,指距(cm)=上肢长(cm)×2.5。结论 新生儿指距与身长,上肢长发育水平一致,其指距范围值可作为判定新生儿指距的标准,指距可作为新生儿生长发育评价指标之一。
Objective To measure the nodal distance of full-term neonates and calculate their normal range values to explore the significance of fingernails in neonatal growth and development evaluation. Methods A total of 762 full-term newborns (397 males and 365 females, 1-3 days old) were enrolled in this study. Face parallel, measuring the distance between the two fingertips, accurate to 1 mm. Results The index of newborns was (50.75 ± 1.69) cm and 50.11 ± 1.61 cm (50.13 ± 1.65) cm, respectively. There was no significant difference between male and female (P> 0.05), while P3-97 was 46.12-53.28 cm Finger length and upper limb length r = 0.8962, P <0.01, and body length r = 0.8871, P <0.01, were highly positive correlation. Refers to the distance and length similar to the length of the finger is slightly longer than the length of the finger to the length of the ratio of 1 / 0.99, the pitch (cm) = length (cm) × 1.01, pitch (cm) = upper limb length (cm) × 2 + 10, finger pitch (cm) = upper limb length (cm) × 2.5. Conclusion Neonatal fingering is consistent with the length and length of upper limbs. The range of index fingering can be used as the criterion to determine the newborn fingering distance, and the fingering distance can be used as one of the indicators of neonatal growth and development.
