The continuous vacuum regulator with the vacuum
cup allows the pressure to be built up and held. After
making the uterine incision and rupturing the
membranes, the surgeon places the vacuum cup over
the occiput, and the previously applied clamp is
removed, the suction is immediately available, and
the vacuum cup becomes attached to the head.
Then, the waiting period for the development of an
adequate vacuum is minimal. Therefore, traction may
be applied in a matter of seconds. Additionally, no cup
detachments (‘pop-offs’) occurred. Lim et al. [13]
and Svenningsen et al. [14] found that there was no
difference in maternal and neonatal outcomes between
procedures with rapid versus slow induction of vacuum.
The present results demonstrated that the U-D interval
was significantly prolonged in M group compared with
V group (86.3±53.9 seconds vs. 65.3±31.2 seconds,
p <0.001).
Previous studies reported that use of the vacuum
extractor at the time of elective cesarean delivery
allow for delivery with less blood loss [2, 15]. However,
in our study, mean blood loss in the vacuum extraction
group was higher than the mean blood loss in the
manual group (576.7±182.9 mL vs. 504.4±204.9 mL)
although this difference was not statistically significant
(p=0.306).
The Apgar scores of the two groups were not
significantly different. Infants did not show evidence
of any scalp remarks because delivery had been
produced more quickly, less traction applied, and
the cup had been attached to the scalp for only a
short period. There were no differences in neonatal
resuscitation between the two groups.
In conclusion, the use of the vacuum extractor
communicating with the hospital piped-vacuum
supply at cesarean section may be a safe and effective
method to affect delivery of the fetal head. Cesarean
section delivery can be simplified by this technique.
