Pt c/o pain and need to “make bm”. Found to be FD and ready to push.
SVE: 10/100/+1
Toco: CTX q2-3min
Pt is in significant pain while pushing and requesting pain medication: infant’s
head has been crowning for approx 2 minutes/too late for epidural or IV
analgesia.
Pt is screaming, thrashing around, and FHT begins to decel to 70s, 80s, then
comes back up to 120s, then decels again. Pt repositioned to lateral decub on
both sides, but unable to stay in these positions, given discomfort.
Episiotomy is cut midline, attempt made to deliver head for approx 30
seconds, then additional space cut, creating 2nd degree episiotomy. Infant is
quickly delivered without instrumentation.
Delivery of vigorous female infant w apgars of 9/9. Cord clamped, cut, and
gases sent. 3 cord placenta delivered spontaneously and intact. Fundus firmed
with fundal massage and pitocin administration. Lidocaine administered
locally and 2nd degree episiotomy repaired with 2-0 and 3-0 vicryl w/o further
complication. No 3rd degree extension into rectal sphincter. Hemostasis
achieved.

Episiotomy
Definition: a surgical incision of the perineum
usually performed at point when perineum is
stretched and distended, just prior to crowning
of the fetal head.
• Median/Midline: vertical incision from fourchette
straight back towards anus
– Easier to repair
• Mediolateral episiotomy: incision ~ perpendicular to
midline, with angle becoming smaller (~45º) beyond
fetal presenting part
– Less extension to rectum
• J incision: hybrid

Episiotomy
The purpose is to increase the diameter of the soft
tissue pelvic outlet, thereby preventing perineal
lacerations, facilitating delivery, and reducing the
time for expulsion of the infant.

Episiotomy:
• One of the most common operations
performed on women
• Prevalence is decreasing

Indication for Episiotomy?
The only indication for episiotomy that cannot be categorically
dismissed is for fetal concerns (non-reassuring tracing, etc) that
arise urgently during advanced labor.
Other historical indications for episiotomy are not evidence-based
and are proven to do more harm than good.

Episiotomy
Other enduring myths about episiotomy
•
•
•
•
It prevents pelvic floor weakness
It is easier to repair than a tear
It heals better than a tear
It minimizes intraventricular hemorrhage in
preterm infants

Evidence against routine use of
episiotomy:
Increases the following:
 Wound extension, dehiscence, infection, and healing time
 Blood loss
 Postpartum pain
 Likelihood of leaking stool and gas (bowel incontinence)
 Dyspareunia
 +/- urine incontinence

Episiotomy: Why is it still performed?
• High-intervention standards for childbirth
• Practice style and values of individual providers
• Practice style and values in specific birth settings
• Influence of colleagues
• Influence of medical education

Avoiding episiotomy:
As early as possible in pregnancy:
• Encourage pts to learn about episiotomy as part of
learning about pregnancy, labor and delivery
• Encourage pt’s to create a birth plan that takes into
account their values, preferences
• Even if you have been the provider for a pt
throughout their entire pregnancy and especially if
you haven’t, ask pts about their birth plans again at
the time of labor/admission.
