BACKGROUND Sample sizes for obstetrical trials are often based on the opinion of investigators about clinically important effect size. We surveyed Canadian obstetricians to investigate clinically important effect sizes required before introducing new treatments into practice to prevent preterm birth. METHODS Questionnaires were mailed to practicing obstetricians, asking the magnitude of pregn...

Objective We describe the successful utilization of a modified rescue cerclage in 32-year-old G4 P1213 woman Afro-Caribbean descent with Diamniotic Dichorionic twin gestation who presented at 20 weeks and 2 days for routine anomaly scan was found to have dilated (1.7 cm) short (0.49 cervix. Design A standard prophylactic cervical done 12 weeks' using Mersilene™ tape. For cerclage, client placed...

Abstract Background Cervical cerclage is a recognised treatment to prevent late miscarriage and pre-term birth (PTB). Emergency cervical (ECC) for dilatation with exposed unruptured membranes less common the potential benefits of are certain. A randomised control trial needed accurately assess effectiveness ECC in preventing pregnancy loss compared an expectant approach. Methods C-STICH2 multic...

We aimed to evaluate the effect of degree cervical dilatation during physical examination-indicated cerclage presenting with premature and bulging fetal membranes on subsequent neonatal outcomes. Throughout a 10-year period, 72 singleton pregnancies in tertiary unit were included divided into two according pre-cerclage dilatation: Group 1 (n = 33) group 2 39) ≤3 cm > 3 cm, respectively. Latency...
