Mercer and colleagues found a statistically significant decrease in late onset infection and intraventricular hemorrhage (IVH) in a group of premature infants with delayed cord clamping compared with a group with immediate cord clamping. They point out that their results are consistent with a recent Cochrane Review and propose a reasonable explanation for the differences that they observed. However, it is interesting to note that the level of significance for both comparisons (p = 0.03) was relatively small. While the data was grouped and analyzed appropriately, the study did involve multiple comparisons and I would question how confident one can be that the differences observed here were not actually due to chance alone. Also, with respect to the observed differences in IVH rates, almost all of the IVH that occurred was Grade 1 or Grade 2, which is clearly a reflection of the excellent obstetrical and neonatal care provided to these infants. While a larger study might have demonstrated a statistically significant difference in Grade 3 and Grade 4 IVH, in this study no statistically significant difference in the rate of severe IVH between the groups was demonstrated.

Mercer JS and colleagues have done a well designed study to demonstrate effects of delayed cord clamping in very preterm infants. The sample size was too small to demonstrate the difference in the primary outcome BPD, but the positive trends for DCC merits further studies. Given the lack of adverse events in the DCC group, some might consider adopting this practice until definitive studies are completed.
