What is the optimal pharmacological management of retained placenta?

In this Practice article (BMJ 2014;349:g4778, doi:10.1136/bmj. g4778) by Duffy and colleagues, an error occurred in the first paragraph. The authors provided a correction [http://www.bmj. com/content/349/bmj.g5173]which requires further clarification. The second sentence should now read: “The third stage of labour can be managed actively or physiologically, defined by the National Institute for Health and Care Excellence (NICE) 1 as follows: Physiological management of the third stage involves a package of care which includes all of these three components: no routine use of uterotonic drugs, no clamping of the cord until pulsation has ceased, and delivery of the placenta by maternal effort. Active management of the third stage involves a package of care which includes all of these three components: routine use of uterotonic drugs, early clamping and cutting of the cord, and controlled cord traction.”
