ABSTRACT
We compared outcomes for neonates with forceps-assisted, vacuum-assisted, or cesarean
delivery in the second stage of labor. This is a secondary analysis of a randomized
trial in laboring, low-risk, nulliparous women at ≥36 weeks' gestation. Neonatal outcomes
after use of forceps, vacuum, and cesarean were compared among women in the second
stage of labor at station +1 or below (thirds scale) for failure of descent or nonreassuring
fetal status. Nine hundred ninety women were included in this analysis: 549 (55%)
with an indication for delivery of failure of descent and 441 (45%) for a nonreassuring
fetal status. Umbilical cord gases were available for 87% of neonates. We found no
differences in the base excess (p = 0.35 and 0.78 for failure of descent and nonreassuring fetal status) or frequencies
of pH below 7.0 (p = 0.73 and 0.34 for failure of descent and nonreassuring fetal status) among the
three delivery methods. Birth outcomes and umbilical cord blood gas values were similar
for those neonates with a forceps-assisted, vacuum-assisted, or cesarean delivery
in the second stage of labor. The occurrence of significant fetal acidemia was not
different among the three delivery methods regardless of the indication.
