What is used for cervical ripening?
- Prostaglandin E2 or PGE2 gel is used for cervical ripening
- This helps with softening and effacing the cervix
- It is used in women at or near term for the induction of labor
-
What are forms of PGE2?
- Prepidil a form of PGE2 gel is a intracervical application
- Cervidil is a intravaginal insert, it is 2-cm-square piece of cardboard like material and placed on the posterior vagina. It is slow releasing
-
Advantages of Prostaglandin Use?
- can be removed easliy
- causes cervical ripening
- shorter labor
- lower requirements for oxytocin
- vaginal birth w/in 24 hrs
- reduced need for C-section
-
Disadvantages of Prostaglandin Use?
- uterine hyperstimulation
- nonreassuring fetal status
- higher incidence of postpartum hemorrhage
- uterine rupture in absence of previous incision
-
Contraindications of PGE2?
- previous uterine incision (C-section)
- compromised cardiovascular
- hepatic or renal function
- women with asthma or glaucoma
- sensitivity to PGE2
- unexplained vaginal bleeding
-
PGE2 insertion procedure (Prepidil)?
- used only by hospital birthing unit
- comes in prefilled syringe
- a catheter is inserted into the endocervix
- gel is injected
- cath has sheild so gel can't pass to internal os
-
PGE2 insertion procedure (Cervidil)?
- vaginal insert is placed in the posterior vagina
- if it becomes dislodge reinsert by nurse
- if hyperstimulation occurs remove insert
- if active labor occurs remove insert
-
The use of Misoprostol (Cytotec)?
- a synthetic PGE1used to soften and ripen the cervix to induce labor
- available in tablet of insert
- increased rate of uterine rupture
- delivery w/in 24 hours
- low ceserean birth rates
-
Guidelines for the use of Misoprostol (cytotec)?
- use one in 3rd trimester for ripening and induction
- 1/4 of tab or 25 mcg for initial dose
- wait 4 hours before Pitocin is given
-
Contraindication of Misoprostol (Cytotec)?
- three uterine contractions in 10 minutes
- maternal asthma
- previous cesarean or other uterine scar
- placenta previa
- nonreassuring fetal status
-
Transcervical Catheter?
- this is the use of a balloon catheter
- used for cervical ripening and mechanical dilation
- a 25 mL to 80 mL balloon is used to dilate the cervix with inflation
- can be used w/ vaginal Cytotec, Pitocin, or extra-amniotic saline infusion
-
Nurse Care Management
- assess maternal vital signs
- apply EFM
- intruct women to remain lying down after insertion
- put rolled blanket or wedge under right hip to shift uterus
- monitor for hyperstimulation
- monitor FHR abnormalities
- administer tocolytic if hyperstimulation occurs
- give antiemetics, antipyretics and antidiarrheal agents
- assess location of cathether
- women should remain in recumbent position
- no vaginal examinations
- provide bedpan avoid ambulation
-
Labor Induction?
Is the stimulation of uterine contractions before the spontaneous onset of labor, with or w/o ROM, for the purpose of accomplishing birth
-
Labor Augmentation?
Is the stimulation of uterine contractions when spontaneous contractions have failed to result in progresssive cervical kiationor the descent of the fetus
-
Indications of Induction or Augmentation?
- DM
- Renal disease
- Preeclampsia
- HTN disorders
- PROM
- Chorioamnionitis
- Fetal demise
- Postterm gestation
- IUGR
- Isoimmunization
- Hx of rapid labor or precipitous labor
- Nonreassuring antepartal testin
- Severe oligohydramnios
- Macrosomia
-
Contraindications of Labor Induction or Augmentation?
- abnormal FHR patterns
- breech presentations
- unknown presentations
- multiple gestation
- polyhydramnios
- presenting fetal part above the maternal inlet
- severe HTN
- maternal heart disease
-
Methods for Inducing or Augmenting Labor
- Stripping membranes
- nonpharmalogic method
- physician inserts fingers as far as possible into internal cervical os
- rotates the finger 360 degrees, twice
- motion seperates the amniotic membranes
- stripping is thought to release PGF2oc from amniotic membranes or PGE2 from cervix
- after procedure: uterine contractions, cramping, and bloody discharge can occur
-
.....continue
- Oxytocin infusion:
- requires IV adminstration
- intiates uterine contractions to induce labor
- goal is to achieve 3 UCs in 40-60 seconds in 10 min
-
.....continue
- Complementary methods:sexual intercouse/love making:-)
- self or partner stimulation of women's nipple
- blue/black cohosh
- evening primrose oil
- red rapberry leaves
- homeopathic solutions: caulophyllum, pulsatilla
- castor oil
- acupressure/acupuncture
-
Nursing Care Management on Induction and Augmentation
- obtain vital signs
- begin oxytocin infusion
- obtain fetal monitor recording
- inform women of blood tinge d/c from procedure
- monitor frequency, intensity, and duration
-
Amiotomy?
- it is artificial rupture of amniotic membranes
- most common procedure for induction of labor
- the cervix has to be dilated at least 2 cm
- can be used to augment labor too
- labor will be shortened 1-2 hours
- allows you to insert a fetal monitor electrode
- allows you to insert intrauterine pressure cath
-
Advantages of an Amniotomy?
- contractions elicited are similiar to SROM
- women does not require intensive monitoring as with oxytocin
- EFM is possible
- color and composition of fluid can be evaluated
-
Disadvantages of Amniotomy?
- birth needs to happen w/in 24 hours b/c of increase risk for infection
- danger of prolapsed cord is increased esp. if presenting part is not pressed down on cervix
- molding and compression of fetal head b/c of loss of amnio fluid
- fetal injury due to the amniohook
- bleeding due to undiagnosed vasa previa
- severe variable decels which increases C-section
-
Amniotomy Procedure?
- first assess fetus presentation, position, station, and FHR
- physician introduces an amniohook into vagina, through the cervix, and against the amniotic membrane
- a small tear is made in the amniotic membrane
- amniotic fluid is now allowed to escape slowly
-
Nursing management for an Amniotomy?
- Assess fetal presentation, position, and station (amniotomy is usually delayed until engagement)
- Place disposable pads and towel under buttocks
- Assess FHR immediately before and after amniotomy
- Check for prolapsed cord
- Inspect amnio fluid for amount, color, odor, meconium and blood
- Clean and dry perineal area
- Advise women fluid will continue to come out
- Strict sterile technique vaginal exam should be used
- Reduce the amount of vaginal exams done b/c of increase infection
- Monitor temperature every 2 hours
- Bed rest is maintained
-
Amnioinfusion?
Is a technique by which a volu
