Intravenous fluid given to women with pre-eclampsia may be a necessary form of treatment; however, intravenous fluid therapy can also cause iatrogenic pulmonary oedema.

Clinical experience, combined with available evidence and a reasoned approach are the basis for a suggested management algorithm.
