Assisted Vaginal Delivery: When is Vacuum or Forceps Needed?

What is Assisted Vaginal Delivery?

Assisted vaginal delivery, also known as operative vaginal delivery, is a clinical procedure where an obstetrician utilizes specialized medical instruments to facilitate the birth of the baby during the second stage of labor. This intervention serves as a safe alternative to emergency cesarean section in specific clinical scenarios, ensuring both maternal and fetal safety. It is a critical component of comprehensive maternity care and pregnancy care provided across healthcare facilities in Saudi Arabia.

The Difference Between Vacuum Extraction and Forceps

The choice of instrument depends on the clinical assessment, the position of the fetal head in the birth canal, and the obstetrician's expertise. Vacuum extraction involves placing a soft plastic or rigid metal cup onto the baby's head, secured by gentle suction, to assist the mother's pushing efforts. Forceps delivery utilizes two curved metal instruments resembling large spoons, positioned carefully around the baby's head to guide them through the pelvis.

Indications for Assisted Vaginal Delivery

Assisted delivery is never routine; it is indicated only when specific clinical criteria are met to protect the mother or baby. Key indications include:

• Maternal Exhaustion: When prolonged pushing has depleted the mother's energy, rendering her unable to deliver the baby spontaneously.
• Fetal Distress: Non-reassuring fetal heart rate patterns indicating potential oxygen deprivation, necessitating immediate delivery.
• Prolonged Second Stage of Labor: Lack of progress in the pushing stage for over 2 to 3 hours, taking into account the use of epidural anesthesia.
• Maternal Medical Conditions: Underlying cardiovascular or neurological conditions where prolonged pushing poses a significant health risk to the mother.

Prerequisites for Safe Instrumental Delivery

Before proceeding with vacuum or forceps, the obstetrician must confirm that strict safety conditions are satisfied:

1. The cervix must be fully dilated (10 cm).
2. The amniotic membranes must be ruptured.
3. The fetal head must be engaged in the maternal pelvis (at an appropriate station).
4. The exact position of the fetal head must be determined.
5. Maternal pelvic adequacy must be confirmed.
6. The maternal bladder must be emptied using a temporary catheter to prevent injury.

Maternal Consent, Alternatives, and Transition to C-Section

In alignment with Saudi healthcare regulations and patient rights, informed consent must be obtained from the mother or her guardian after a clear explanation of the procedure. The clinical team will outline the indications, benefits, potential risks, and the alternative option, which is an emergency cesarean birth. The operating theater is typically prepared in advance so that if the assisted vaginal attempt does not succeed within a safe timeframe, a rapid transition to a C-section can be executed smoothly.

Potential Effects on Mother and Newborn

Many expectant mothers express concern regarding the potential risks of vacuum extraction on the baby. While these tools are highly safe when used by qualified specialists, minor and temporary side effects can occur:

Fetal Effects:

• Chignon: A temporary swelling of the scalp caused by the vacuum cup, which typically resolves within 24 to 48 hours.
• Cephalohematoma: A minor collection of blood under the scalp that resorbs naturally over several weeks without treatment.
• Neonatal Jaundice: A slightly increased risk of jaundice due to the breakdown of red blood cells in minor bruises, easily managed with phototherapy if needed.

Maternal Effects:

• Vaginal or perineal lacerations.
• Temporary urinary retention or stress incontinence, which improves with pelvic floor exercises.
• Localized perineal pain during the initial postpartum weeks.

Episiotomy and Postpartum Recovery Care

According to the Saudi Ministry of Health guidelines, routine episiotomy is not recommended. However, assisted vaginal delivery using vacuum or forceps is a recognized medical indication for performing an episiotomy to prevent severe, irregular perineal tears.

Postpartum care for the perineal area is essential for optimal healing and infection prevention:

• Keep the perineal area clean and dry, changing sanitary pads frequently.
• Use warm sitz baths as prescribed by your doctor after the first 24 hours.
• Apply cold packs or ice wrapped in a clean cloth to reduce swelling and discomfort during the first few days.
• Maintain a high-fiber diet and drink plenty of fluids to prevent constipation and strain on the sutures.
• Initiate gentle pelvic floor (Kegel) exercises once cleared by your obstetrician during your postpartum follow-up.

Estimated Costs of Assisted Delivery in Saudi Arabia

Assisted vaginal delivery services are provided free of charge to Saudi citizens in public, military, and university hospitals. In the private healthcare sector, the use of vacuum or forceps is billed as an additional procedure on top of the standard vaginal birth package. This additional fee typically ranges from SAR 1,500 to SAR 3,500. The base cost of a normal delivery in private hospitals in Saudi Arabia ranges between SAR 5,000 and SAR 12,000, depending on the hospital's classification, location, and the consultant's expertise.
