This section includes a series of clinical guidelines for the management of common conditions in obstetrics and fetal medicine. They have been developed fundamentally on the basis of scientific evidence, as the product of an exhaustive bibliographic review, and in some specific aspects in the clinical experience of the Obstetrics and Reproductive Medicine department of the Vall d’Hebron Hospital.

These protocols can be especially useful for consultation by professionals involved in the follow-up of these cases, but they must be analyzed with caution when applied in a setting other than that of a specialized center. Likewise, they have not been designed as information for patients, and for their correct understanding it is essential to have specialized medical training.
