Abstract

Operative vaginal birth retains an important role in current obstetric practice. However, there is an increasing trend in the rate of cesarean section in Korea. Surgical delivery is more advantageous than cesarean section, but the rate of operative vaginal delivery is decreasing for various reasons. Furthermore, there is no unified technique for vacuum extraction delivery. In this context, this review was performed to provide details of the necessary conditions, techniques, benefits, and risks of operative vaginal delivery. Future research should focus on overcoming the limitations of operative vaginal delivery.

Figure

  • Fig. 1 Statistics of delivery mode in the United States. Operative vaginal delivery in the United States tends to decrease gradually. Also, vacuum extraction is more dominant than forceps.

  • Fig. 2 Diagram of appropriate of vacuum cup placement. The vacuum cup must be placed at the flexion point to maximize adhesion. At this time, the center of the vacuum cup should be 6 cm from the anterior fontanelle and 3 cm from the posterior fontanelle on the same line of the sagittal suture line.

  • Fig. 3 Diagram of vacuum cup traction technique. Vacuum cup applied when the uterine cervix is fully dilated, the amniotic membrane ruptured and the fetal head engaged with the maternal pelvis when the fetal head begins to appear, the direction of traction should be gradually changed to upward.
