Clinical analysis on 183 cases of umbilical cord around the neck

To study the effect of UCAN on perinatal infants and the factors associated with UCAN.183 cases of UCAN were selected and compared with 554 cases of non-UCAN, clinical factors were analyzed.No UCAN was found in short cord group. There were more cycles of cord entanglement in the long cord group than in the normal length cord group; the difference was significant (P0.01). In UCAN group, the rate of fetal distress was 20.77%, newborn asphyxia 10.38%, fetal death 2.19%, cesarean section 74.86%.[Conclusion]UCAN is correlated with the length of umbilical cord. More cycles of cord entanglement resulted from long umbilical cord has more chances of causing fetal distress, newborn asphyxia, fetal death and cesarean section.
