Childbirth is a remarkable yet complex process. While many deliveries proceed naturally without complications, some situations require medical assistance to ensure the safety of both mother and baby. One of the most important instruments used in assisted vaginal delivery is forceps.
Understanding the role of forceps in obstetrics is essential for medical students, trainees, and healthcare professionals — and even helpful for expectant parents who want to be informed about possible delivery scenarios.
In this comprehensive guide, we’ll explore:

- Types of forceps
- Indications for use
- Step-by-step procedure
- Advantages and disadvantages
- Risks and complications
- Modern perspectives on forceps delivery
What Are Forceps in Obstetrics?
Obstetric forceps are specialized surgical instruments used to assist in the delivery of a baby during vaginal childbirth. They resemble large curved tongs or spoons and are designed to gently grasp the baby’s head to guide it through the birth canal.
Forceps are typically used when:
- Labor is prolonged
- The baby is in distress
- The mother is unable to push effectively
- Quick delivery is necessary
The primary goal is to ensure a safe and controlled delivery while minimizing risk.
History of Forceps in Obstetrics
Forceps have been used for centuries. They were first developed in the 17th century by the Chamberlen family in England. Over time, improvements in design, sterilization, and obstetric training have made forceps deliveries safer and more precise.
Although cesarean sections and vacuum extraction are more common today, forceps remain an important part of obstetric practice.
Anatomy of Obstetric Forceps
Obstetric forceps typically consist of:
- Two blades – Curved to fit around the baby’s head
- Shanks – Connect blades to handles
- Lock mechanism – Aligns and secures blades together
- Handles – Used by the physician to apply traction
The blades are carefully shaped to match the contours of the fetal head and maternal pelvis.
Types of Forceps in Obstetrics
There are several types of forceps, each designed for specific clinical situations.
1. Simpson Forceps
- Long and slightly curved
- Used when the fetal head is molded
- Common in typical assisted deliveries
2. Elliot Forceps
- Shorter and rounded
- Suitable for less molded fetal heads
- Often used in low-forceps deliveries
3. Kielland Forceps
- Minimal pelvic curve
- Used for rotational deliveries
- Helps correct malposition (e.g., occiput posterior)
4. Piper Forceps
- Specifically designed for breech deliveries
- Used to deliver the after-coming head
Each type has a specific role depending on fetal position and clinical needs.
Indications for Using Forceps in Obstetrics
Forceps delivery may be indicated in the following situations:
1. Prolonged Second Stage of Labor
If labor stalls and pushing is ineffective, forceps may assist delivery.
2. Maternal Exhaustion
When the mother is too fatigued to continue pushing safely.
3. Fetal Distress
If fetal heart monitoring indicates distress, quick delivery may be required.
4. Medical Conditions in the Mother
Such as:
- Heart disease
- Severe hypertension
- Neurological conditions
These conditions may require minimizing prolonged pushing.
5. Rotational Assistance
Forceps can help rotate the baby’s head into the correct position.
Prerequisites for Forceps Delivery
Before applying forceps, certain conditions must be met:
- Cervix fully dilated
- Membranes ruptured
- Baby’s head engaged
- Known fetal position
- Adequate anesthesia
- Empty bladder
- No cephalopelvic disproportion
Careful assessment ensures safety.
Procedure: How Forceps Delivery Is Performed
Here is a simplified overview:
- Patient positioning in lithotomy position
- Adequate anesthesia administered
- Assessment of fetal head position
- Insertion of first blade gently along the baby’s head
- Insertion of second blade
- Locking the blades together
- Controlled traction during contractions
- Guided delivery of the baby’s head
- Removal of forceps once the head crowns
The physician must apply steady and controlled traction to avoid injury.
Advantages of Forceps in Obstetrics
Forceps offer several clinical benefits:
✅ Rapid Delivery
Useful in emergencies where immediate birth is needed.
✅ Controlled Traction
Allows precise guidance of the baby’s head.
✅ Rotational Capability
Kielland forceps can rotate malpositioned fetal heads.
✅ Avoidance of Cesarean Section
In some cases, forceps delivery prevents the need for surgical birth.
✅ Beneficial in Breech Deliveries
Piper forceps assist with after-coming head delivery.
Disadvantages of Forceps Delivery
Despite their usefulness, forceps have potential drawbacks.
❌ Maternal Injury Risk
- Vaginal tears
- Perineal trauma
- Increased need for episiotomy
❌ Neonatal Injury Risk
- Facial bruising
- Temporary facial nerve palsy
- Skull marks
- Rare intracranial injury
❌ Requires High Skill Level
Proper training and experience are essential.
❌ Declining Experience
With increased cesarean rates, fewer practitioners are highly skilled in forceps use.
Maternal Risks Associated with Forceps
Possible maternal complications include:
- Perineal lacerations
- Postpartum hemorrhage
- Urinary retention
- Pelvic floor injury
- Long-term incontinence (rare but possible)
Proper technique significantly reduces these risks.
Neonatal Risks Associated with Forceps
Possible neonatal complications include:
- Facial bruising
- Scalp lacerations
- Facial nerve injury (usually temporary)
- Skull fractures (rare)
- Intracranial hemorrhage (very rare)
Most minor injuries resolve without long-term effects.
Forceps vs Vacuum Extraction
Forceps and vacuum extraction are both used for assisted vaginal delivery.
| Feature | Forceps | Vacuum |
|---|---|---|
| Traction Strength | Stronger | Moderate |
| Rotation Ability | Yes | Limited |
| Maternal Trauma | Higher risk | Lower risk |
| Neonatal Scalp Injury | Less common | More common |
| Skill Required | High | Moderate |
Choice depends on physician expertise and clinical scenario.
Forceps vs Cesarean Section
In some cases, forceps can avoid cesarean delivery.
Advantages over C-section:
- Shorter recovery time
- Lower surgical risk
- Less postoperative pain
However, if forceps attempt fails, emergency C-section may be required.
Modern Trends in Obstetric Practice
Over the past few decades:
- Cesarean section rates have increased
- Vacuum extraction is more commonly used
- Forceps training has declined in some regions
However, forceps remain an essential tool in skilled hands, especially for complex or rotational deliveries.
Training and Skill in Forceps Delivery
Successful forceps delivery depends heavily on:
- Accurate fetal position assessment
- Proper blade placement
- Controlled traction
- Clinical judgment
Training programs emphasize simulation and supervised practice to maintain proficiency.
Ethical and Clinical Considerations
When considering forceps delivery:
- Informed consent must be obtained
- Risks and benefits must be explained
- Alternative options discussed
- Continuous fetal monitoring required
Shared decision-making is critical.
When Forceps Should NOT Be Used
Contraindications include:
- Incomplete cervical dilation
- Unknown fetal position
- Unengaged fetal head
- Cephalopelvic disproportion
- Preterm baby with fragile skull (relative contraindication)
Safety always takes priority.
Future of Forceps in Obstetrics
While usage has declined in some areas, forceps continue to be:
- Important in specialized centers
- Essential for rotational deliveries
- Valuable in settings with limited surgical access
Continued training ensures this skill is preserved.
Conclusion: The Role of Forceps in Obstetrics
Forceps in obstetrics remain a vital tool in assisted vaginal delivery. When used appropriately and skillfully, they:
- Enable safe, rapid delivery
- Prevent complications
- Reduce need for surgical intervention
- Assist in complex fetal positioning
Although modern obstetrics offers alternatives like vacuum extraction and cesarean section, forceps continue to have an important place in maternal care.
The key lies in proper patient selection, skilled technique, and informed decision-making.
