Birth Related Procedures

  • Linda L. Franco RN MSN NE-BC

  • Blue = history

  • Green = Need to know

  • Red = important to know


Version turning of the fetus

Version (turning of the fetus)

  • Methods

    • External

      • External cephalic version (ECV) fetus is changed from breech to cephalic thru external measures

    • Internal

      • Rarely used, occurs when the 2nd fetus during a vaginal twin birth isn’t doing well. Med is given to relax uterus and dr reaches in and pulls the fetus out. Usually the woman is given a c-section

  • Risks

    • Hypoxia

    • Fetal Distress

    • AbruptioPlacentae


Criteria for external version

Criteria for External Version

  • Must be at least 36 or more weeks gestation

  • Must have a Reactive NST immediately prior

  • Fetal breech is not engaged

    • So if they baby is breech and is not engaged (or dropped)


Contraindications for version

Contraindications for Version

  • Maternal problems

    • Uterine anomalies, uncontrolled PIH (pregnancy induced hypertension), third trimester bleeding

    • Make sure the mom has IV access for meds or blood or whatever

  • Complications of pregnancy

    • ROM, oligohydramnios, polyhydramnios, placenta previa

  • Previous C/S or uterine surgery

  • Multiple gestation

  • Nonreassuring FHR

  • IUGR


Amniotomy

Amniotomy

  • Defined as: Artificial rupture of the amniotic membrane

    • Need 2 cm of dilation

  • Indications

    • Induce labor

    • Internal monitoring

  • Risks

    • Infection

    • Prolapse of cord

    • Abruptioplacentae


Cervical ripening

Cervical Ripening

  • Soften the cervix

  • Cervical readiness is the most important thing when thinking about inducing labor in a mom

  • Successful induction

  • Management of intrauterine fetal death

  • Drugs – Prostaglandins, Cytotec


Induction augmentation of labor

Induction & Augmentation of Labor

  • Indicated – health of mother & baby

  • Elective – convenience

  • Risks

    • Hypertonic uterine activity

    • Uterine rupture

    • Water intoxication

      • Retention of water with sodium depletion. Pt is lethargic, nauseated, vomiting, and in severe cases may convulse or go into coma

      • Antidiuretic effect of oxytocin decreases water exchange in the kidney and reduces urinary output leading to fluid overload


Induction con

Induction con.

  • Amniotomy

  • Cervical Ripening (or readiness)

    • Bishop score of 8 or 9

      • Table 23-1 – 1 pg. 540

      • The higher the score the more likely it is that labor will occur

      • Cervical readiness is the most important criteria for labor induction

  • Natural methods – sexual intercourse, breast stimulation, enemas, castor oil

  • Drugs

    • Oxytocin

    • Prostaglandins

  • Oxytocin Administration

    • Secondary IV

    • Infusion started slowly

    • Contractions q 2-3 min with relaxation between


Bishop scoring system

Bishop Scoring System


Oxytocin infusion

Oxytocin Infusion

  • RL 1,000 ml with 10 - 20 units pitocin; infuse at 1-2 mu/min

  • Observe fetal response

  • Observe for uterine hypertonus

    • Nursing actions

      • Stop Pitocin

      • Increase primary IV rate

      • Turn to left side

      • Give Oxygen

      • Notify physician

  • You want stable contractions every 2-3 mins that last 40-60 seconds, this is why we give pitocin

  • Risk of pitocin is hyperstimulation of the uterus. If this happens we must discontinue the pitocin. If you don’t then placenta perfusion isn’t taking place and the baby isn’t getting oxygen


Pitocin infusion calcualtion 20 u pitocin don t need to know for exam

PITOCIN INFUSION CALCUALTION – 20 u pitocin (don’t need to know for exam)

1000ml x 2mu x 1u x 60min = 6ml

20u min 1000mu 1hr hr

1000ml x 1mu x 1u x 60min = 3ml

20u min 1000mu 1hr hr


Pitocin infusion calcualtion 10u pitocin don t need to know for exam

PITOCIN INFUSION CALCUALTION – 10u pitocin (don’t need to know for exam)

1000ml x 2mu x 1u x 60min = 12ml

10u min 1000mu 1hr hr

1000ml x 1mu x 1u x 60min = 6ml

10u min 1000mu 1hr hr


Amnioinfusion

Amnioinfusion

  • Infusion of warmed sterile Normal saline into the uterus through an IUPC (intrauterine pressure catheter)

  • If the mom’s bag of water isn’t enough then we put more fluid in there. Helps the baby move around.

  • May also be used to dilute miconium (sp?) if the infant inhales the miconium and it’s not diluted they can inhale it, which is bad

  • Indications

    • Oligohydramnios, relieve cord compression, dilute meconium stained amniotic fluid


Episiotomy

Episiotomy

  • Surgical incision of the perineum

  • Indications

    • Decrease pressure on fetal head

    • Control direction of extension of the vaginal opening

    • Clean incision easier to repair and heals better

    • Cuts by the dr heal faster than if they rip on their own…

  • Risks

    • Infection

    • Kind of makes it more likely to have an anal sphincter tear

  • Nursing care

    • Ice to perineum

    • Observe for edema, hematoma, redness

  • Controversial


Forceps assisted birth

Forceps Assisted Birth

  • Metal Instruments shaped to grasp fetal head

  • Indications

    • Shorten second stage of labor

    • Any condition that threatens the mother or baby that will be relieved with birth

    • Regional anesthesia has effected the moms motor functions… like they are too drugged to push

  • Risks

    • Vaginal laceration or hematoma

    • Trauma to baby’s face or scalp

    • Intracranial or subgaleal hemorrhage


Forceps assisted birth1

Forceps Assisted Birth


Vacuum extraction

Vacuum Extraction

  • Suction to help deliver fetal head

  • Risks

    • Cephalhematoma

    • Hyperbilirubinemia

      • Because of bruising

    • Intracranial hemorrhage


Vacuum extraction1

Vacuum Extraction


Cesarean section

Cesarean Section

  • Incision in abdominal and uterine walls

  • Indications

    • Complete placenta previa or abruption

    • CPD

    • Malpresentations

    • Herpes – active lesions

    • Fetal distress

    • Chronic Maternal Disease

    • Previous C/S


Cesarean section con

Cesarean Section con.

  • Risks

    • Anesthesia

    • Infection

    • Hemorrhage

    • Trauma to baby

  • Procedure

    • Skin incision

      • Cut into the uterus…

      • Transverse is usually low and invisible once healed, takes longer

      • Vertical is better, used when baby needs to be out quick

    • Uterine incision


Vaginal birth after cesarean vbac

Vaginal Birth After CesareanVBAC

  • Low transverse uterine incision

  • Contraindication with vertical uterine incision

  • Risks

    • Hemorrhage

    • Uterine Rupture

    • Hysterectomy

    • Infant death

    • Neurological complications
