    Description / Table of Contents: Summary None of the betamimetics have an exclusively tocolytic effet. By stimulating the cardiovascular β-receptor, they also cause a substantial increase in the heart rate and a decrease in blood pressure. We administered 4–5 μg/min of Fenoterol to 13 patients during the first stage of labour. This led to complete inhibition of labour. To reduce cardiac side effects, a primarily cardiac β-blocker (5 mg Atenolol or 20 mg Metoprolol) was also given. The maternal and fetal heart rates were measured by ECG and by fetal scalp-electrode, respectively. The fetal heart rate remained largely unchanged, both during the Fenoterol infusion as well as during the additional administration of the β-blocker. The maternal heart rate, which increased under the influence of the Fenoterol, fell (p ≤ 0.01) but did not return to normal. In all cases the β-blockade led to a brief increase in uterine activity.
    Notes: Zusammenfassung Neben dem tokolytischen Effekt verursachen Betasympathikomimetika eine erhebliche Steigerung der Herzfrequenz und eine Blutdruckerniedrigung durch Stimulation der kardialen und vaskulären Betarezeptoren. Dreizehn Patienten erhielten während der Eröffnungsperiode 4–5 μg/min Fenoterol i.v. Nach vollständiger Wehenhemmung wurde wegen der unerwünschten Kreislaufreaktionen zusätzlich ein Betablocker mit vorwiegend kardialer Wirkung (Atenolol 5 mg oder Metoprolol 20 mg) verabreicht. Die Registrierung der Herzfrequenzen erfolgte über mütterliches EKG und fetale Skalpelektrode. Sowohl während der Fenoterol-Infusion als auch während der zusätzlichen Verabreichung des Betablockers änderte sich die fetale Herzfrequenz nur unwesentlich. Die Fenoterol-bedingte mütterliche Tachykardie konnte gesenkt (p ≦ 0,01), aber nicht vollständig aufgehoben werden. In allen Fällen führte die Betablockade zu einer kurzzeitigen Steigerung der Uterusaktivität.
