Normally, the cord length of time, on average about 55 cm, but there are a great individual variety.Order experimental and clinical arguments suggest that cord length is influenced by the quality of amniotic fluid and fetal mobility.
For example, in cases with oligoemnios sarcinp, is noticeably shorter cord. In pelvic presentations, the average length of cord is approximately 5 cm lower.
1. Absence of cord (agreement).It is an extremely rare event in which the fetus is in direct contact with the placenta.
2. Short cord.This is rebound clinical enitate when, due to primitive or windings. Cord length is less than 35 cm. This length is necessary to avoid embarrassment delivery mechanism (32-35 cm distance from the placenta normal background inserted to vulva).
This short cord can cause:- Abnormal presentations;- Dezinsertia or cord rupture with severe hemorrhage to the fetus;- Intrapartum fetal distress;- Off the normally inserted placenta with hematoma formation;- Birth defects of the mechanism;- Uterine inversion.
Diagnosis is supported by the following aspects:- High status that applies to the presentation, sets and engage with difficulty;- Presentation on expulsion during descent and does not remain at the level reached during the contractions, but their termination ascensioneaza again, this amendment adds rhythm BCF, which are bradycardia, sometimes arrhythmic.
Conduct rapid completion of delivery targets for signs of fetal distress, usually parts forceps application.
3. Long CordIf the term is umbilical cord length exceeds 70 cm, reaching values of 300 cm. This entity does not have a particular clinical interest, except in the long cord is complicated by real nodes, prolapsing, circular vascular thrombosis.
