[Platelet function during long term inhibition of labour by fenoterol/verapamil (author's transl)]. 1978

R C Briel, and S Kunz, and E Kidess

Platelet function has been studied in 22 patients (methods according to Born and Breddin) during tocolysis with long term administration of intravenous Fenoterol/Verapamil. The extend and speed of platelet aggregation, according to the Born test, were constant in the following 12 days except for a small increase on the second day. The phase of disaggregation remained unchanged. The reaction time to collagen was prolonged up to the 3rd-4th day. Spontaneous platelet aggregation showed a tendency to decrease up to day 3--4; thereafter, there was a return to the original values. The present data show that a hemostatic action in platelet function cannot be expected during long term tocolysis. Thus, there is no evidence that Fenoterol acts as an inhibitor of platelet aggregation in pregnancy.

D007752 Obstetric Labor, Premature Onset of OBSTETRIC LABOR before term (TERM BIRTH) but usually after the FETUS has become viable. In humans, it occurs sometime during the 29th through 38th week of PREGNANCY. TOCOLYSIS inhibits premature labor and can prevent the BIRTH of premature infants (INFANT, PREMATURE).
