Can be applied without full dilatation of cervix
a. Vacuum extractor can be an alternative to obstetric forceps when the patient is in the second stage of labor and the head is low in the obstetric outlet of the pelvis.
b. The vacuum extraction has both advantages and drawbacks over forceps application.
c. Main advantage of this procedure is that it can be used in malrotation of the head and also when the cervix is not fully dilated. It does not occupy space as is the case with forceps blades and it requires less technical skill on part of the surgeon. It can also be conveniently used when the head is high as is the case of a second twin for effecting prompt delivery.
d. However the main disadvantage is in the time taken for delivery which makes it unsuitable if fetal distress is present.
