What is a mid forceps delivery?

What is a mid forceps delivery?

A mid forceps delivery occurs when the head is engaged, but less than +2 cm station. A high forceps delivery, when the fetal head is unengaged, is no longer performed in modern obstetrics. The choice of forceps to use is based on the operator’s training and the type of forceps delivery.

What are the indications of vacuum extraction?


  • Cervix fully dilated.
  • Membranes previously ruptured.
  • Engagement of the fetal head.
  • The clinician has determined the position of the fetal head.
  • Fetal weight estimation performed previously.
  • Pelvis thought to be adequate for vaginal delivery.
  • Adequate anesthesia (often an epidural)

When should vacuum extraction be discontinued?

A vacuum extractor should not be used at gestations of less than 34 weeks +0 days. The safety of vacuum extraction at between 34 weeks +0 days and 36 weeks +0 days of gestation is uncertain and should therefore be used with caution.

Can you use forceps at +2 station?

Forceps delivery is usually indicated for a fetal head position at station +2 or lower, with an injury rate that is lower than for vacuum extraction.

What is vacuum extraction assisted delivery?

During a vacuum-assisted vaginal delivery, a health care provider applies the vacuum — a soft or rigid cup with a handle and a vacuum pump — to the baby’s head to help guide the baby out of the birth canal. This is typically done during a contraction while the mother pushes.

Can the vacuum used in birth cause brain damage?

These devices can play an important role in the birth of a child and help doctors to overcome complications that arise. However, if misused, a vacuum extractor can cause a child to suffer serious injuries, including permanent brain damage and brachial plexus injuries.

Why doctors use vacuum during delivery?

During vaginal delivery, your doctor may use a vacuum to help remove your baby from the birth canal. This procedure makes delivery more rapid. It may be needed to avoid injury to the baby and to avoid cesarean section.

What is brow presentation in childbirth?

In a brow presentation, the fetal head is midway between full flexion (vertex) and hyperextension (face) along a longitudinal axis. The presenting portion of the fetal head is between the orbital ridge and the anterior fontanel. The face and chin are not included.

How common are vacuum deliveries?

While somewhat rare — only about 5 in every 200 babies are born with the help of a vacuum extraction — you should know that the procedure is safe for both mother and baby.

Which birth injury is most commonly associated with a vacuum assisted birth?

Subgaleal hematoma It occurs when blood accumulates just under the scalp. Since the subgaleal space is large, a significant amount of blood can be lost in this area of the skull. This is why subgaleal hematoma is considered to be the most dangerous complication of vacuum-assisted delivery.

How can we minimize adverse events in vacuum-assisted vaginal delivery?

In vacuum-assisted vaginal delivery, proper application and use of the vacuum device, including limiting application time to 20 minutes and three pulls, as well as avoiding multiple disengagements of the vacuum (or “pop-offs”), can minimize adverse events.

What is the best book on vacuum extraction in obstetrics?

Vacca A. Handbook of Vacuum Extraction in Obstetric Practice. 1st ed. London, UK: E. Arnold; 1992:32. 8. Damron DP, Capeless EL. Operative vaginal delivery: a comparison of forceps and vacuum for success rate and risk of rectal sphincter injury. Am J Obstet Gynecol. 2004;191 (3):907–910. 9.

When can the vacuum be removed during delivery?

The vacuum can be removed when the fetal J aw is reachable ( Figure 3D 10 ). In the past, use of forceps was often considered after an unsuccessful attempt at vacuum delivery.

Why is episiotomy no longer recommended during vaginal delivery?

Episiotomy during an operative vaginal delivery is no longer recommended because it can increase the risk of perineal injury. Operative vaginal delivery using both a vacuum device and forceps has been associated with worse neonatal outcomes than using a single instrument.
