Effect of alternative positions of neonates prior to delayed cord clamping on placental transfusion: a randomized control trial

Abstract

Objective: To determine the effect of alternative positions (relative to placenta) of normal term neonates, prior to the recommended delayed cord clamping, on placental transfusion and short-term neonatal outcome.Methods: Normal term neonates born vaginally were randomly assigned to be placed either on mother’s abdomen (Group AL, n = 97) or 20 cm below the introitus (Group BL, n = 102) for 90 seconds after delivery. Subsequently the cord was clamped. Outcome measures were anthropometry, hematological profile including ferritin at birth and at 3–4 months; and adverse effects, polycythemia, and jaundice.Results: Both groups had comparable outcome measures at birth. At 3–4 months, mean hemoglobin (AL: 12.0 ± 0.9 g/dl, BL: 12.3 ± 1.1 g/dl; p = .02, 95% CI: 0.03–0.58) and hematocrit (AL: 36.1 ± 2.7%, BL: 37 ± 3.2%; p = .01, 95% CI: 0.1–1.75) were significantly higher in BL group. Anthropometry, serum ferritin, incidence of anemia and iron deficiency at 3–4 months were similar in both groups. There was no significant difference in polycythemia, jaundice requiring phototherapy or respiratory distress between the two groups.Conclusions: Placing the baby below the placenta resulted in a statistically significant increase in hemoglobin and hematocrit at 3–4 months without any adverse outcomes. However, this meager quantum of increase did not translate into reduction of risk of anemia or improvement in iron stores.
