Effect of delayed versus early umbilical cord clamping on neonatal outcomes and iron status at 4 months: a randomised controlled trial

Authors reply: Ethical issues - early or late clamping of umblical cord

22 November 2011

We would like to thank professor Shah for his appreciation of our work. As for ethical consideration, the results from the Chaparro et al was known when we commenced our study, but it was questioned if this was applicable in a high income country. In 2006, as part of the planning for the study, we performed a telephone survey in Sweden and concluded that 2/3 of labour departments practiced early cord clamping, including the labour department at the hospital of Halmstad, where the study was performed.
The regional ethical committee approved our study as well.
