OBJECTIVES The aims were to assess the placental and fetal circulation during nifedipine tocolysis within the first 48 hours of therapy. METHODS Placental and fetal circulation was assessed in Doppler ultrasound examination prior to nifedipine administration and then after 24 and 48 hours. Maternal heart rate and PI in uterine arteries were evaluated as well as FHR, RI and PI of UA and MCA. E...

Aim of Work: To compare the safety & efficacy of oral nifedipine with transdermal nitroglycerin in the inhibition of preterm labour. Methods: This study included 60 women in preterm labour, randomly divided into two groups, the first 30 patients received oral nifedipine and the second 30 patients used transdermal nitroglycerin (NTG). Patients in preterm labour with a single gestation, between t...

Objective: Preterm delivery is an important cause of perinatal morbidity and mortality. This study was conducted with an objective to assess the effect of ritodrine on perinatal mortality as compared to isoxsuprine and the effect of ritodrine on maternal morbidity and neonatal morbidity in comparison to isoxsuprine with the extent to which delivery was delayed. Design: A randomized study with 2...

OBJECTIVE The fetal fibronectin test is advocated to facilitate the management of women presenting with threatened preterm labour, but is underutilised in Hong Kong. This study aimed to provide experience with this test and evaluate its utility in a local setting. DESIGN Prospective cohort study. SETTING A university-affiliated hospital in Hong Kong. PATIENTS Women presenting with symptom...

This systematic review was to identify available evidence on the effectiveness of tocolysis in inhibiting preterm delivery for women with threatened extremely preterm birth, multiple gestations, and growth-restricted babies, and their infants' outcomes. A comprehensive search using MEDLINE, Embase, the Cochrane Library, CINAHL, POPLINE and the WHO Global Health Library databases was conducted o...
