More than 12% of deliveries in the United States that occur at less than 37 weeks gestation preterm labor (PTL) represents the largest single reason for preterm birth (PTB). Attempts to prevent PTB have been unsuccessful. This paper of maintenance tocolytic therapy will examine the efficacy and safety of the drugs, both oral and sub...
OBJECTIVE To determine the efficacy and safety of nifedipine as a tocolytic agent in women with preterm labor. STUDY DESIGN A systematic review and metaanalysis of randomized controlled trials. RESULTS Twenty-six trials (2179 women) were included. Nifedipine was associated with a significant reduction in the risk of delivery within 7 days of initiation of treatment and before 34 weeks' gest...

DESIGN Prospective open study. PARTICIPANTS Sixty-eight women with breech presentation at around 36 weeks of gestation and an attempted external cephalic version under salbutamol that failed, who consent...

OBJECTIVES The aims were to investigate whether any changes in placental and fetal circulation were observed during fenoterol tocolysis within the first 48 hours of therapy. MATERIAL AND METHODS Doppler evaluation of placental and fetal circulation was performed prior to fenoterol administration and then after 24 and 48 hours. Maternal heart rate and pulsatility index (PI) in uterine arteries...

At present, there is evidence that tocolysis for 48 hours is useful in women with threatened preterm labour at least before 32 weeks. This allows transfer of the patient to a perinatal centre, and maximizes the effect of corticosteroids for improved neonatal survival. It is questionable whethe...
