Overview
Forceps delivery is an assistedâvaginal birth in which a speciallyâshaped instrument (the forceps) is used to help guide the babyâs head through the birth canal. While the procedure can be lifesaving for both mother and infant, it can also lead to a group of shortâ and longâterm problems collectively referred to as âforceps delivery complications.â These complications may involve the motherâs pelvic floor, perineum, cervix, or even the newborn.
Who is affected? Any pregnant person who undergoes a forcepsâassisted birth is at risk, but certain groups experience higher rates:
- Firstâtime mothers (nulliparous) â the cervix and pelvic floor are less âexperienced.â
- Women with a prolonged second stage of labor or fetal distress.
- Patients with preâexisting pelvic floor weakness, diabetes, or obesity.
How common is it? In the United States, forceps deliveries account for about 2â3âŻ% of all births, down from more than 15âŻ% in the 1970s due to the rise of cesarean sections and vacuum extraction. According to the Centers for Disease Control and Prevention (CDC), roughly 30,000â40,000 forcepsâassisted births occur each year in the U.S., meaning that millions of women worldwide could experience related complications.
Symptoms
Complications can manifest immediately after delivery or develop weeks to months later. Below is a comprehensive list of common symptoms, grouped by the body system they affect.
Maternal Symptoms
- Pain or bruising in the perineum. Often described as a deep ache that worsens with sitting or walking.
- Vaginal or rectal bleeding. Small spots are normal, but soaking pads or clots larger than a golf ball warrant attention.
- Incontinence. Involuntary leakage of urine (stress or urge incontinence) or feces (fecal incontinence) due to sphincter or nerve injury.
- Pelvic organ prolapse. A feeling of heaviness or a bulge descending into the vagina.
- Persistent swelling or hematoma. A firm, tender lump in the vaginal wall or groin.
- Difficulty moving the legs. Rarely, a nerve stretch can cause temporary weakness or numbness.
- Emotional distress. Postâtraumatic stress, anxiety, or depression related to a difficult birth.
Neonatal Symptoms
- Facial bruising or âfetal scalpâ marks. Usually harmless but may cause parental concern.
- Cephalohematoma. A collection of blood under the skull that can cause a raised bump.
- Skull fracture or intracranial hemorrhage. Extremely rare but serious; signs include seizures, lethargy, or an enlarging head circumference.
- Facial nerve palsy. Temporary drooping of one side of the face.
- Low Apgar scores or need for resuscitation.
Causes and Risk Factors
Forceps complications arise from two broad mechanisms: mechanical injury from the instrument itself, and secondary effects of the labor circumstances that necessitated its use.
Mechanical Causes
- Excessive traction. Pulling too hard can tear perineal tissue, lacerate the anal sphincter, or stretch the pudendal nerves.
- Improper placement. Misâaligned blades can damage the vaginal wall or fetal skull.
- Prolonged use. Keeping forceps in place for more than a few minutes increases tissue ischemia and bruising.
Laborârelated Risk Factors
- Fetal distress or nonâreassuring heart rate patterns.
- Maternal exhaustion or inadequate uterine contractions (uterine inertia).
- Malposition of the baby (occiput posterior, asynclitic presentation).
- Maternal conditions that limit pelvic floor elasticity: diabetes, obesity (BMIâŻâ„âŻ30), or previous pelvic surgery.
- Operative delivery after a prolonged second stage (>âŻ3âŻhours in a nulliparous woman).
Diagnosis
Timely identification of a forcepsârelated complication relies on a combination of clinical assessment, patient history, and, when necessary, imaging or specialized testing.
Maternal Evaluation
- Physical examination. The provider inspects the perineum, vagina, and anus for tears, bruising, or hematoma. Digital rectal exam assesses sphincter integrity.
- Pelvic floor testing. Using a perineometer or manometry to quantify muscle strength; useful when incontinence is reported.
- Neurologic exam. Checks sensation in the pudendal nerve distribution and assesses lowerâextremity strength.
- Imaging.
- Transâperineal ultrasound or MRI to evaluate deep tears or occult sphincter injuries.
- CT or MRI of the pelvis if a large hematoma is suspected.
Neonatal Evaluation
- Head exam. Palpation for skull fractures, cephalohematoma, or subgaleal hemorrhage.
- Neurologic assessment. Monitoring for seizures, abnormal tone, or facial palsy.
- Imaging. Cranial ultrasound (in preâterm infants) or CT/MRI if intracranial bleed is suspected.
Treatment Options
Management is tailored to the specific complication and its severity.
Maternal Treatments
- Pain control. NSAIDs (ibuprofen) or acetaminophen for mildâmoderate pain; shortâcourse opioids for severe discomfort.
- Perineal repair. Surgical suturing of lacerations (layers 1â4) ideally within 12âŻhours of birth; use of absorbable monofilament sutures (e.g., VicrylÂź).
- Hematoma evacuation. Large or expanding hematomas may require incision and drainage under anesthesia.
- Pelvic floor physical therapy. Biofeedback, Kegel exercises, and manual therapy to restore muscle tone.
- Fecal or urinary incontinence.
- Behavioral therapy (bladder training, bowel regimen).
- Pharmacologic agents: anticholinergics for overactive bladder, duloxetine for stress urinary incontinence.
- Surgical options: sphincteroplasty for gradeâŻIII/IV anal tears, midâurethral sling for stress urinary incontinence.
- Psychological support. Counseling or postpartum support groups to address anxiety, depression, or birthârelated trauma.
Neonatal Treatments
- Observation. Most minor bruises and cephalohematomas resolve spontaneously over 2â4âŻweeks.
- Compression bandage. Gentle pressure for small cephalohematomas to limit expansion.
- Surgical intervention. Indicated for skull fractures with depressed segments or large subgaleal hemorrhage (may require blood transfusion).
- Physical therapy. For facial nerve palsy, facial massage and eye protection (lubricating drops, patching).
- Neurologic monitoring. Serial head circumference measurements and neuroâimaging if seizures or abnormal tone develop.
Living with Forceps Delivery Complication
Even after successful treatment, many patients experience lingering effects that require ongoing selfâcare.
Daily Management Tips
- Pelvic floor exercises. Perform a set of Kegels three times daily; aim for a 10âsecond hold, 10 repetitions.
- Stool softeners. Bulkâforming agents (psyllium) or osmotic laxatives (polyethylene glycol) reduce straining.
- Hydration. Drink at least 2â3âŻL of water per day to keep tissues supple.
- Weight management. Maintaining a healthy BMI lessens pressure on pelvic structures.
- Postâurethral care. Empty bladder completely; use doubleâvoiding technique.
- Protect skin. Use a breathable perineal pad and avoid harsh soaps.
- Followâup appointments. Keep scheduled visits with obstetrician, pelvic floor therapist, and, if needed, a colorectal surgeon.
Prevention
While it is impossible to eliminate all risk, several evidenceâbased strategies can dramatically reduce the likelihood of forcepsârelated complications.
- Optimized labor management. Use evidenceâbased protocols for labor progression (e.g., the WHO 2018 partograph) to avoid unnecessary prolonged second stage.
- Selective use of forceps. Reserve forceps for clear indications (fetal distress, failure to progress with adequate contractions) and consider vacuum extraction or cesarean section when risk is high.
- Skilled operator. Ensure that the provider has documented competency and ongoing simulation training; outcomes are better when experienced obstetricians perform the procedure.
- Prenatal pelvic floor conditioning. Prenatal classes that include pelvic floor awareness can improve tissue elasticity.
- Control modifiable maternal conditions. Glycemic control in diabetes, weightâmanagement programs for obesity, and smoking cessation reduce tissue fragility.
- Fetal positioning strategies. Encourage maternal positioning (handsâandâknees, lateral tilt) during labor to facilitate optimal head descent.
Complications
If a forceps delivery complication is not identified or treated promptly, it can cascade into more serious problems.
- Chronic pelvic pain. Persistent nociceptive pain may develop from nerve entrapment.
- Severe incontinence. Untreated sphincter tears can lead to permanent urinary or fecal leakage, markedly reducing quality of life.
- Pelvic organ prolapse. Progressive descent of the bladder, uterus, or rectum, potentially requiring surgical repair.
- Infection. Open lacerations or hematomas can become colonized, leading to cellulitis or sepsis.
- Psychological sequelae. Postâtraumatic stress disorder (PTSD) after a traumatic birth is reported in up to 9âŻ% of women after operative vaginal delivery (American Journal of Obstetrics & Gynecology, 2021).
- Neonatal sequelae. Undiagnosed intracranial hemorrhage can cause developmental delay, seizures, or cerebral palsy.
When to Seek Emergency Care
- Severe or worsening vaginal bleeding (soaking a pad in 5âŻminutes or passing large clots).
- Sudden, intense perineal or pelvic pain that does not improve with overâtheâcounter analgesics.
- Loss of sensation or movement in the legs or perineal area.
- Inability to pass urine or stool, accompanied by a feeling of fullness or swelling.
- FeverâŻâ„âŻ38.0âŻÂ°C (100.4âŻÂ°F) with chills, especially if accompanied by foulâsmelling discharge.
- Rapidly enlarging lump or swelling in the vulva or groin (possible expanding hematoma).
- For the newborn: persistent vomiting, seizures, excessive sleepiness, bulging fontanelle, or a rapidly increasing head circumference.
Prompt evaluation can prevent permanent damage and preserve both maternal and infant health.
