Umbilical cord entanglement and intrapartum complications

Background and aim: The purpose was to evaluate the outcomes of pregnancies complicated by umbilical cord entanglement. Methods: Pregnant women referred to Niknafs maternity hospital of Kerman with singleton, vertex and term pregnancies were selected for the study. Pregnancies with no umbilical cord entanglement served as comparison group. A comparison of the frequencies between the two groups was performed by x2 testing and a comparison of means by student t-test. Results: Of the 478 deliveries, the frequency of umbilical cord entanglement was 40.2%, frequency of nuchal cord entanglement was 34.3% and around limbs or trunk was 5%. The frequency of two or more cord entanglements was 6.49%. Pregnancies with umbilical cord entanglement were more likely to exhibit an abnormal fetal heart rate pattern (P<0.001). The inflicted infants were also more likely to have low I- and 5-minute Apgar scores < 7 (P<0.05) and to have mecunium (P<0.05). The mean of umbilical cord entanglements among infants with mecunium was more than that of the infants without mecunium (P<0.05). Conclusion: Umbilical cord entanglement was associated with a greater risk of mecunium, abnormal fetal heart pattern during labor, low 1- and 5-minute Apgar sores < 7 and adverse fetal outcomes. It is possible to detect this problem with Doppler ultrasonography during prenatal scan.
