[Beta-mimetic tocolysis: maternal and fetal side-effects]

The literature on materno-foetal effects of the administration of beta-mimetic tocolytics has been examined. Data and series observed show a certain number of unwanted maternal and foetal effects of a metabolic and cardiocirculatory nature. Although these are usually reversible, they may, in conditions of latent pathology, turn into serious accidents. Critical evaluation of research carried out makes it possible to reiterate the usefulness of these drugs, always providing that the absolute need to use them can be demonstrated, and that their use is preceded by careful evaluation of the patient's cardiocirculatory and metabolic condition.
