Compared with planned repeat low-transverse cesarean section, vaginal birth after cesarean section (VBAC) is not associated with increased risk of maternal or neonatal mortality (strength of recommendation [SOR]: B). Morbidity is slightly increased, as evidenced by higher uterine rupture rates and some neonatal outcome measures (SOR: B).

BACKGROUND The national health objective for the year 2000 is to have an overall Cesarean section rate of 15 percent, a primary Cesarean section rate of 12 percent, and a vaginal birth after Cesarean (VBAC) rate of 35 percent. The current national statistics for the most recent year available, 1991, are 23.5 percent, 17 percent, and 24.2 percent, respectively. This study evaluates a VBAC progra...

OBJECTIVE The objective of the study was to more precisely estimate the effect of maximum oxytocin dose on uterine rupture risk in patients attempting vaginal birth after cesarean (VBAC) by considering timing and duration of therapy. STUDY DESIGN A nested case-control study was conducted within a multicenter, retrospective cohort study of more than 25,000 women with at least 1 prior cesarean ...

Methods The study comprised a sub-sample of 190 healthy term infants from one centre participating in the Canadian Healthy Infant Longitudinal Development (CHILD) birth cohort study. Mode of delivery was determined from hospital records, and mothers reported infant diet at 3, 6 and 12 months postpartum. Antibiotic exposure was documented from hospital and prescription records. Gut microbiota wa...

Uterine rupture (UR), a potentially life-threatening condition for both mother and infant, occurs in <0.1% of all pregnant women and <1% of women attempting vaginal birth after cesarean section (VBAC) (1-4). During 1990-1997, the proportion of vaginal deliveries among women who had previous cesarean sections (CS) in Massachusetts increased 50%, from 22.3% to 33.5% (5). Concern about a correspon...

Vaginal birth after previous caesarean section (VBAC) should be encouraged to decrease the rising trend of cesarean section rate. The success rate of vaginal birth after caesarean section varies from institution to institution and is general around 60 to 70%. In recent years there has been a reported decline in the rate of VBAC all over the world. Offering VBAC becomes a challenging decision fo...

Caesarean section (CS) rates have been increasing worldwide and have caused concerns. For meaningful comparisons to be made World Health Organization recommends the use of the Ten-Group Robson classification as the global standard for assessing CS rates. 2625 women who birthed over a 12-month period were analysed using this classification. Women with previous CS (group 5) comprised 10.9% of the...
