Поздняя перевязка пуповины существенно снижает риск железодефицита у новорожденых

[Dr.Vad]

Данное исследование показало, что и в развитых странах это актуально (предыдущие подобные исследования были проведены в странах Африки и Лат. Америки, где риск железодефицита у новорожденных существенно выше)

At 4 months of age, infants showed no significant differences in haemoglobin concentration between the groups, but infants subjected to delayed cord clamping had 45% (95% confidence interval 23% to 71%) higher mean ferritin concentration (117 μg/L v 81 μg/L, P < 0.001) and a lower prevalence of iron deficiency (1 (0.6%) v 10 (5.7%), P = 0.01, relative risk reduction 0.90; number needed to treat = 20 (17 to 67)). As for secondary outcomes, the delayed cord clamping group had lower prevalence of neonatal anaemia at 2 days of age (2 (1.2%) v 10 (6.3%), P = 0.02, relative risk reduction 0.80, number needed to treat 20 (15 to 111)). There were no significant differences between groups in postnatal respiratory symptoms, polycythaemia, or hyperbilirubinaemia requiring phototherapy.
