SOUZA, Alex Sandro Rolland et al. Mechanical method of induction of labor in high-risk pregnant women with previous cesarean section. Rev. Bras. Ginecol. Obstet. [online]. 2015, vol.37, n.3, pp.127-132. ISSN 0100-7203.  https://doi.org/10.1590/SO100-720320150005120.

PURPOSE:

To describe the maternal and fetal outcomes with the use of the Foley catheter for induction of labor in high-risk pregnant women with previous caesarean section.

METHODS:

An interventive and descriptive study was conducted from November 2013 to June 2014. A total of 39 pregnant women at term, with a live fetus, cephalic presentation, estimated fetal weight <4,000 g, with previous cesarean section, medical indications for induction of labor, Bishop score ≤6 and amniotic fluid index >5 cm were included. A number 16F Foley catheter was introduced for a maximum of 24 hours, and was considered to be satisfactory when the patient began labor within 24 hours.

RESULTS:

Labor was successfully induced in 79.5% of pregnant women. Nine women achieved vaginal delivery (23.1%), with a frequency of 18% of vaginal births occurring within 24 hours. The main indications for the induction of labor were hypertensive disorders (75%). The mean interval between the placement of the Foley catheter and the beginning of labor and delivery were 8.7±7.1 and 14.7±9.8 hours, respectively. Meconium-stained amniotic fluid was observed in two patients; and an Apgar score <7 in the first minute was detected in 5 newborns (12.8%).

CONCLUSIONS:

The Foley catheter is an alternative for the induction of labor in women with previous caesarean section, despite the low vaginal delivery rate.
