VBAC/TOLAC
VBAC---vaginal birth after cesarean
TOLAC---trial of labor after cesarean
Decision making
Non-repeating condition (why was previous
cesarean done?)
Desire to avoid cesarean birth
Ability to do emergency cesarean birth
Benefits mother by shortening recovery time
Risks
Possibility of uterine rupture (what kind of incision
was made on uterus?)
Successful VBAC
How can we help?
Review prenatal record for risks
Ensure informed consent, Additional consent if
oxytocin is used, as risk increases
Continuous EFM and 1:1 nursing care
Assess for normal labor progression and S/S
uterine rupture
MD must remain immediately available
throughout active labor
Ensure ability to perform emergency C/S
Elective Cesarean Section
ACOG definition:
A primary C/S at maternal request in the absence of
any medical or obstetric indication.

Getting Ready
Operating Room Preparation
 Circulating RN is responsible for operating
room readiness
 Patients with the same health status and
condition should receive a “comparable”
level of care regardless of where that care is
provided within the hospital.
Joint Commission
 “Comparable” care to that provided in the
main hospital surgical department is
recommended by ASA (2006) and JCAHO
(2007); however, “equivalent” care is not
required.
Operating Room Preparation
Cleaning of the OR
Equipment and Supplies
Suction, medical gases
Blood products, implants, devices or special equipment
present?
Electrosurgical unit

 Informed Consent
 Pre-Procedural Verification
First step done prior to entering the OR.
It includes patient verification and OR
readiness.
Second step completed in the OR prior

Single injection , repeat bolus or continuous infusion
Interrupts transmission of pain impulses along nerve roots.
Lower doses allow motor function to remain intact
Sympathetic blockade is less than with a spinal

amount of drug used and absorbed than with a spinal
LA Toxicity…what’s that?

Malignant Hyperthermia (MH)
An autosomal dominant inherited muscle
disorder that can occur in susceptible people
on exposure to certain drugs used to produce
general anesthesia or muscle relaxation during
anesthesia.
Theory is that MH reactions are set off by
sudden release of large quantities of CA++
which increases metabolic activity of muscle.
Body fuels are rapidly consumed.
Malignant Hyperthermia
Triggers
All volatile inhalation anesthetics
Depolarizing muscle relaxants
Succinylcholine
Malignant Hyperthermia
 blood potassium =rapid, irregular heart rate
and possible arrest.
 CO2 = rapid, deep breathing
 O2 = brain damage
 myoglobin can block kidneys=kidney failure
 heat= fever, may reach 110F within minutes
Treatment
HELP!
Stop the triggering agent(s)
Dantrolene within 5 minutes
Monitor & Supportive treatment
Notify MHAUS

Scenario 1
 A G2P1 delivers by unscheduled repeat C/S. The delivery was uneventful.
She was given a rapid sequence mask induction because of advanced
labor, previous classical incision and maternal anxiety. Upon arrival in
PACU, she is in right recumbent position,briefly arrousable, maintaining
her airway with good air exchange. VS are stable, O2 saturation is 97% on
room air.
 After about 10 minutes, you hear gurgling sounds and note she has
vomited, then gasped. She begins to cough and gag. You suction her
mouth and throat, then administer an antiemetic. She is more awake and
has no recurring N/V. Soon, she begins to breath more rapidly and says, “I
can’t get enough air.” You notice crowing/stridor on inspiration. Her O2
sat drops to 80’s. Her voice is hoarse and panicky.
 What do you suspect? What do you need to know? What do you do?
 After your interventions, she is breathing more rapidly. Her saturation is
82%. She is fully conscious.
 What do you do next?
Scenario 2
 A 28 year old G2P1 at term is receiving an epidural anesthetic
prior to scheduled Cesarean Section. She has no allergies, is
in good health with an unremarkable prenatal history.
 You assist the woman into a fetal position on her side, and
attach monitoring equipment. A liter of LR is hanging and you
open it to provide a bolus.
 The anesthesiologist proceeds with the epidural. As he
finishes injecting the epidural, the woman’s B/P drops to
80/37, her heart rate drops from 84 to 52 and O2 sat falls.
She says,”I can’t breathe, my chest is heavy.”
Scenario 3
 A 26 year old southeast Asian woman at about 32 weeks,
arrives in the recovery room after an emergency C/S, under
rapid induction sequence, for abruption. As you proceed with
your initial assessment, you note that a red string is tied
around her upper abdomen and a pattern of old scars on the
woman’s abdomen that look like burns. You know from a
class on Transcultural nursing that it is believed this string
placed during pregnancy forms a protective circle keeping the
baby from harm and that burning the skin allows illnesses
and evil out of the mother during her pregnancy.
Scenario 3 (cont)
 As you continue with your assessment, the woman’s jaw
dislocates. You call for the anesthesiologist to assist in
realigning her jaw. Recovery proceeds with 2 more incidence
of jaw dislocation.
 When the woman has recovered from anesthesia and is
stable, you prepare to move to her room. You feel that the
language barrier has hindered your communication with this
woman. Before she leaves you, she tries to tell you
something. Frustrated, you are glad an interpreter has been
called in for the nurse who is taking over her care. You give
report to the new RN. The pt is reunited with her husband in
her postpartum room.
Scenario 4
24 yr old G1 with no prenatal care presents to
the Birth Center with a prolapsed cord and
non-reassuring fetal heart rate pattern. She is
taken for emergency C/S. Rapid sequence
induction is initiated using propofol and
succinylcholine. The anesthesiologist finds he
cannot open the pt’s mouth, but can
bag/mask ventilate.
Scenario 4 (cont)
After a few minutes of ventilation and
propofol boluses, the jaw relaxes and pt is
intubated. Anesthesia is maintained with 50%
Nitrous Oxide in O2, rocuronium and 1%
isoflourane. Baby delivers, surgery is
completed and mother is taken to PACU. HR
140, R26, T104
Scenario 5
A 31 year old G2/1 is having a scheduled
repeat C/S. Significant Hx is anxiety, breech
presentation with this pregnancy and obesity.
She has been taken to the operating room
where the anesthesiologist is placing an
epidural. You are assisting with positioning the
patient. After several unsuccessful attempts,
the anesthesiologist final gets the epidural
placed. With each attempt your patient
becomes more anxious. You are now helping
to position her in left lateral tilt, and have
called the surgeon into the room.
Scenario 5 Continued
Just as you are placing a bolster under the
patient’s right hip, she says, “ What is
happening to me? I feel really strange. “ She
is becoming more restless.
What do you think might be happening? How
can you help her?
Scenario 5 Continued
Your patient becomes very restless. Her
monitors are difficult to read due to her
agitation. You notice some twitching of her
facial muscles and she tells you “I taste
something weird”. Now what do you think is
happening?
Scenario 5 Continued
 Your patient begins to seize. The
anesthesiologist is attempting to protect her
airway. What can you do to help? What could
happen next? How will you prepare?
