[Effect of subpartal tocolysis on maternal cardiovascular parameters with subsequent cesarean section in general anesthesia].
The influence of subpartal beta-sympathicomimetic tocolysis on a subsequent Caesarean section with halothane as inhalational anaesthetic was examined in 42 pregnant women. Alterations in the heart rate, blood pressure and heart action during the operation were measured. 23 patients (group "bolus") received fenoterol monotherapy. In 19 patients (group "iv-tocolysis") fenoterol was combined with the cardioselective beta-1-blocking agent metoprolol. ⋯ Arrhythmias of ectopic origin and sinus bradycardias, however, were found seldom. The incidence of arrhythmias in the three groups during Caesarean section did not differ significantly. There was no evidence for an increased occurrence of arrhythmias following beta-sympathicomimetic tocolysis.
