Background: Women with preterm labor put in an arrest phase by tocolytic therapy, are at increased risk of recurrent preterm labor. The aim of this study is to evaluate vaginal progesterone suppositories as compared to intramuscular type in order to prevent preterm labor in women with episodes of threatened preterm labor. Methods: This prospective longitudinal...

The objective of this study was to assess quality of care for premature labor at public maternity facilities in Rio de Janeiro, Brazil, using referents, indicators, and standards of care derived from scientific evidence. The standard utilized in the process analysis for use of betamimetic tocolytics was 100%, considering the related referents. For outcome analysis, the standard applied was the ...

OBJECTIVES Beta-agonists play an important role in tocolytic treatment. In light of recent changes in the Polish medical care system, we decided to assess the effectiveness of oral continuous treatment (in 2012) and compare it with a 3-day intravenous administration of fenoterol (in 2013). The aim of our study was to contrast cost and effectiveness of fenoterol therapy in pregnant women at risk...

Objective. Evaluating changes in the power spectral density (PSD) peak frequency of the electrohysterogram (EHG) caused by nifedipine in women with preterm contractions. Methods. Calculation of the PSD peak frequency in EHG contraction bursts at different times of nifedipine treatment in women in gestational age 24 to 32 weeks with contractions. Results. A significant (P < .05) decrease of PSD ...

Intravenous magnesium sulfate tocolysis remains a North American anomaly. This therapy rose to prominence based on poor science and the recommendations of authorities. However, a Cochrane systematic review concluded that magnesium sulfate is ineffective as a tocolytic. The review found no benefit in preventing preterm or very preterm birth. Moreover, the risk of total pediatric mortality was si...

Ion channels are interesting molecules since they mediate not only uterine contraction but also uterine relaxation. We have examined the expression, function, and correlation between the large conductance calcium-activated potassium (BKCa) channel, beta2 adrenoceptor (AR), and long-lasting (L) type calcium (Ca2+) channel. These are the main channels and receptor that are involved in the uterine...

Objective: To compare the success rate of nifedipine administration as a tocolytic agent and bed rest for preventing uterine contraction of pregnant women with threatened preterm labour. Methods: A total of 188 pregnant women with threatened preterm labour between 26-35 weeks were enrolled in this study. Cervical measurement was performed in all patients. All women in each group (94 cases) were...

Pyridine-4-carboxylic acid hydrazide, commercially known as isoniazid (INH), is an antitubercular drug and is now widely used together with rifampicin and streptomycin for the chemotherapy of tuberculosis. Ritodrine hydrochloride (RTH), chemically, 1-(4-hydroxyphenyl)-2-[2-(4-hydroxyphenyl)ethylamino]propanol is a potent tocolytic drug and is a selective β2-adrenoceptor agonist and is used to c...
