Abstract
: Objective: evaluate deferred cord clamping as compared to umbilical cord milking in enhancement of placenta-fetal blood transfusion among full term vaginally delivered new born. Study design: A randomized controlled trial. Study setting: Ain Shams University Maternity Hospital. Patients: 1000 vaginally delivered full term pregnant women were included, 500 underwent deferred cord clamping (DCC) and the other 500 underwent cord milking. Results: patients’ characteristics were similar in both groups. Mean neonatal weight before DCC was 3.10 ± 0.29 kg (2.51-3.91 kg) while after DCC was 3.17 ±0.30 kg. The differences in weight and placental transfusion volume was 74.16 ± 9.66 gm (60-90 gm) and 77.87 ± 10.14 ml (63-94.5) respectively. The mean neonatal weight before cord milking was 2.51-4.22 (3.11 ± 0.30) while after milking was 3.16 ±0.31 (2.19-4.28). The differences in weight and placental transfusion volume among cord milking were 52.36 ± 7.68 (40-60 gm) and 54.98 ± 8.06 (42-63) respectively. DCC showed non-significant differences compared to and cord milking group regarding birth Weight before procedure (3.10±0.29) (3.11±0.30) (P=0.416), birth Weight after procedures (3.17±0.30) (3.16±0.31) (P=0.553), whereas there was significant difference regarding weight difference in gm (74.16±9.66) (52.36±7.68) (p<0.001) and placental Transfusion Volume (in ml) (77.87±10.14) (54.98±8.06) (P<0.001). Linear regression showed that the deferred clamping is the only independent factor that may affect either weight differences or placental transfusion. Conclusion: DCC is much better than cord milking in placental transfusion in normal vaginal delivery full term neonates; however large scale multicenter study are required to prove these finding
