PENGARUH INDEKS KOIL TALI PUSAT TERHADAP INDEKS PONDERAL BAYI BARU LAHIR KEHAMILAN ATERM

Abstract

Background : Umbilical cord is a connective tissue between the placenta and fetus which has an important function in interaction between mother and fetus during pregnancy. Circulatory disorders on umbilical cord can cause asphyxia of the fetus’ organs and metabolisms, which can be acute or chronic, so that it will affect outcomes of the newborn. Aims : To know the influences between coiling index of the umbilical cord to ponderal index of the newborn on an aterm pregnancy. Methods : This study was a cross sectional observational research. The samples are pregnant women which has aterm baby’s delivery (37-42 weeks) who were treated in Obstetrics and Gynecology Unit in RSUP Dr. Kariadi Semarang, Bunda Maternity Hospital Semarang, Puskesmas Halmahera Semarang and Puskesmas Ngesrep Semarang. The data collected was secondary data in the form of a ratio scale which was determined by the newborn’s ponderal index and the primary data which was determined by umbilical cord’s coiling index measurement. Statistical tests using normality data test using Saphiro Wilk and followed by non-parametric Spearman Rank Correlation Test. Results : from 50 research data showing result of the mean of umbilical coiling index was 0,35 ± 0,09. The mean of ponderal index was 2,64 ± 0,24. There is a significant negative correlation between umbilical coiling index and ponderal index in newborn with correlation coefficient -0,627 (p < 0,01). Conclusions : There is a significant negative correlation between umbilical cord’s coiling index and newborn’s ponderal index. It shows the higher of umbilical cord’s coiling index or hypercoiling, the lower ponderal index which be measured in newborns. Keys : Umbilical cord’s coiling index, Newborn’s Ponderal index
