The design of the very first RCT about CTG monitoring is interesting, and it raised a question which we really haven’t ever answered fully. Does the use of CTGs create the very problem they are meant to prevent?
@melaniethemidwife (aka Melanie Jackson) has put together a fabulous summary of our recent research paper. Thanks Melanie – you have captured it really well! Small, K. A., Sidebotham, M., Fenwick, J., & Gamble, J. (2020, Sept). Intrapartum cardiotocograph monitoring and perinatal outcomes for women at risk: Literature review. Women and Birth, 33(5), 411-418. https://doi.org/10.1016/j.wombi.2019.10.002
Faith in technology, commercial interests, and liberalisation of tort law had more to do with the introduction of CTG monitoring than research evidence did.
