Effect of Umbilical Cord Milking vs Delayed Cord Clamping on Venous Hematocrit at 48 Hours in Late Preterm and Term Neonates: A Randomized Controlled Trial.

OBJECTIVE To compare the effect of intact umbilical cord milking (MUC) and delayed cord clamping (DCC) on venous hematocrit at 48 (±6) hours in late preterm and term neonates (350/7- 426/7 wk). STUDY DESIGN Randomized trial. SETTING AND PARTICIPANTS All late preterm and term neonates (350/7 - 426/7 wk) neonates born in the labor room and maternity operation theatre of tertiary care unit were included. INTERVENTION We randomly allocated enrolled neonates to MUC group (cord milked four times towards the baby while being attached to the placenta; n=72) or DCC group (cord clamped after 60 seconds; n=72). OUTCOME Primary outcome was venous hematocrit at 48 ((±6) hours of life. Additional outcomes were venous hematocrit at 48 ((±6) hours in newborns delivered through lower segment caesarean section (LSCS), incidence of polycythemia requiring partial exchange transfusion, incidence of hyperbilirubinemia requiring phototherapy, and venous hematocrit and serum ferritin levels at 6 (±1) weeks of age. RESULTS The mean (SD) hematocrit at 48 ((±6) hours in the MUC group was higher than in DCC group [57.7 (4.3) vs. 55.9 (4.4); P=0.002]. Venous hematocrit at 6 ((±1) weeks was higher in MUC than in DCC group [mean (SD), 37.7 (4.3) vs. 36 (3.4); mean difference 1.75 (95% CI 0.53 to 2.9); P=0.005]. Other parameters were similar in the two groups. CONCLUSIONS MUC leads to a higher venous hematocrit at 48 (±6) hours in late preterm and term neonates when compared with DCC.
