Scientific titleSerial weekly membrane sweeping at term in women who planned vaginal birth after one caesarean delivery: a randomised trial
Study acronymSMS_VBAC Trial
Study objectivesThat serial weekly stretching of the cervix and stripping of the membrane from the lower segment of the uterus at term will facilitate the onset of spontaneous labour.
Ethics approval(s)University of Malaya Medical Centre Medical Ethics Committee gave approval on the 25th July 2007 (ref: 601.12)
Health condition(s) or problem(s) studiedPlanned vaginal birth after caesarean
InterventionWeekly cervical stretching and membrane stripping (membrane sweeping) from greater than 36 weeks gestation versus weekly gentle vaginal examination (control).

Random allocation to membrane sweeping or gentle vaginal examination. Allocated treatment conducted as an outpatient procedure in the antenatal clinic. The treatment continues on a weekly basis until delivery has occurred. Standard management of pegnancy and delivery applies.
Intervention typeOther
Primary outcome measure(s)

Spontaneous labour, defined as:
1. Regular painful contractions that had resulted in at least 3 cm of cervical dilation, or
2. Confirmed pre-labour rupture of membranes

Key secondary outcome measure(s)

1. Caesarean delivery
2. Formal labour induction
3. Recruitment to delivery interval
4. Gestational age at delivery
5. Number of membrane sweep or control sessions conducted
6. Bishop score at each session
7. Unscheduled hospitalisation
8. Significant antepartum haemorrhage
9. Prostaglandin and oxytocin use
10. Duration of hospitalisation at birth
11. Epidural analgesia
12. Neonatal outcomes of umbilical artery blood pH, Apgar score at 5 minutes and birth weight

All obtained by the time of discharge from hospital after birth, i.e., no later than 6 weeks after enrolment.
