Pulsatile vs. continuous parenteral tocolysis: comparison of side effects.

Bolus tocolysis has been developed to reduce the dose of fenoterol compared to continuous tocolysis. Whereas the high efficacy of pulsatile application of fenoterol has been shown, the proof of reduced side effects is still lacking. A total of 59 patients with preterm labor were divided in three groups: (1) continuous tocolysis and oral application of magnesium (n=19), (2) continuous tocolysis and parenteral application of magnesium (n=20), (3) pulsatile tocolysis (bolus tocolysis) and oral application of magnesium (n=20).

Changes in plasma elastase during pregnancy and sub partu.

Elastase is produced and released by polymorphonuclear leukocytes (PNMs) during inflammatory processes. Thus, elastase is assumed to be a sensitive marker of infections similar to the well-established C-reactive protein (CRP). It is deactivated predominantly in tissues by alpha1-proteinase inhibitor which forms stable complexes with the elastase molecule (EAPI) that can be detected for several hours.

Fenoterol increases erythropoietin concentrations during tocolysis.

Aims: The present study was carried out to assess the effect of the selective beta2-adrenoceptor agonists on erythropoietin (EPO) production.

Methods: Routine tocolysis with fenoterol (using the regular rate of 2 microg min[-1]) was used as a clinically easily accessible model.

Results: EPO concentrations had doubled 24 h after the start of tocolysis (P < 0.

Fibronectin in the plasma during pregnancy and parturition.

Fibronectin can be detected in the plasma and the extracellular matrix of the uterus of pregnant women. Studies so far have compared individual observations, whilst serial investigations during pregnancy, and during and after parturition have not been carried out. Plasma fibronectin levels were measured in 153 women with healthy pregnancies in relation to the gestational age.

[Comparative study of maternal side effects of various forms of intravenous therapy with fenoterol in premature labor].

Objective: The aim of the present study was to compare different regimes of intravenous fenoterol tocolysis concerning their side effects.

Methods: A total of 59 patients with intravenous tocolysis due to preterm labor has been studied. They were chronologically alternating and thus randomly stratified into three groups: (a) continuous i.
