diabetes and postpartum Flashcards
Hypertonic uterine dysfunction (4)
- Uterus never relaxes btw contractions
- erratic
- poorly coordinated
- contractions: frequent, intense, and painful
- early in labor affecting nulliparous
Hypotonic uterine dysfunction (4)
- during active labor (>4cm)
- poor in quality
- lack intensity: cervix doesn’t dilate or efface
- risk: hemorrhage
Labor induction vs augmentation (3)
- induction: stimulating contractions via medical means
- augmentation: enhancing ineffective contractions after labor has begun
- indications: prolonged gestation, prolonged premature rupture of the membranes, gestational hypertension, (cardiac dz), renal dz, chorioamniotnitis, dystocia, intrauterine fetal demise, and diabetes
labor induction (7)
- cervical ripening
- herbal agents
- hot baths, myths
- sexual intercourse with breast stimulation
- mechanical methods and surgical methods (foley bulb, amni hook)
- pharmacologic agents
- oxytocin
labor induction and augmentation: care management (5)
nursing assessment:
-relative indications; gestational age determination
-fetal status: maternal status: bishop’s score (mom ready for labor, consistency of cervix-soft, firm, midline, higher score more ready for induction)
nursing management:
-explanations
-oxytocin administration
-pain relief and support
umbilical cord prolapse/compression (3)
- when cord lies below presenting part of fetus
- risk factors: long cord (longer than 100 cm), malpresentation (breech), unengaged presenting part, AROM
- management: prompt recognition, relieve pressure on the cord by change in position (hands and knees/trendelendburg), or putting pressure on presenting part and push away from opening
Amnioinfusion (6)
: cervix needs to be somewhat dilated
- dilute meconium passed into the amniotic fluid
- prevent umbilical cord compression
- indications:
- severe variable decelerations due to cord compression
- oligohydramnios due to placental insufficiency
- thick meconium fluid
- nursing management: teaching, maternal and fetal assessment, preparation for possible cesarean birth
about uterine rupture (9)
- very serious obstetric injury
- first sx is sudden fetal distress
- risk factors: (TOL) trial of labor for vbac, inductions: use of pitocin, congenital uterine anomaly, prior uterine surgery, multiparty, trauma
what is uterine rupture (6)
- s/ and sx: vary with extent of rupture, nonreassuring fetal tracing, loss of fetal station, signs of hypovolemic shock
- management: prevention is the best treatment, surgical intervention
shoulder dystocia (6)
- head is born, but anterior shoulder cannot pass under pubic arch
- high risk for neonatal birth injuries: brachial plexus injury, fractured clavicle
- maternal risks: lacerations, excessive blood loss, extension of episiotomy, endometritis
tx for shoulder dystocia (6)
-nurse can apply suprapubic pressure to decrease diameter of shoulders (could fracture clavicle)
-mcroberts maneuver: flex and abduct the legs
-change positions
-episiotomy: from vagina to anus or lateral medial
: dec risk of blood loss, risk of infection (endometritis)
precipitous labor (7)
- active labor < 3 hrs from onset of regular contractions to delivery may be spontaneous or cocaine induced
- not good, very contracted state of uterus
- complications:
- placental abruption
- uterine rupture
- lacerations of maternal structures
- postpartum hemorrhage (most common)
- fetal hypoxia
pre-term labor (4)
- occurrence of regular contractions accompanied by cervical effacement and dilation before the 37th wk of gestation
- major contribute to perinatal morbidity and mortality in the world
- exact cause is unknown
- prevention is the goal
post-term labor (3)
- pregnancy continues past the end of the 42 wk of gestation
- may be from low estrogen
- most places don’t want to wait til this long to induce, but as long as baby is ok should wait
post-term risks (10)
- -maternal risks:
- r/t excessively large infant
- inc risk of dysfunctional labor, birth canal trauma
- interventions more likely to be necessary
- fatigue and psychological runs
- fetal risks:
- prolonged labor
- shoulder dystocia
- birth trauma
- asphyxia
- macrosomia: 4000-4500g
- aging placenta may compromise FHR
care management: post-term (5)
- incr morbidity and mortality after 42 wk
- most docs induce at 41-42 wk
- others allow prey past 41 wk with
- assessment test of fetal well-being normal
- NST and BPP 2x/wk
multiple gestation (2)
- refers to twins, triplets, or more infants within a single pregnancy
- incidence inc d/t infertility tx
operative vaginal births (6)
-forceps-assisted birth
: maternal indications are shortened second stage in event of dystocia
-fetal indications
: distress or certain abnormal presentations
: arrest of rotation
: delivery of head in a breech presentation
forceps-assisted vaginal delivery (4)
- can cause bruising for the baby
- can cause facial nerve damage
- may need to do episiotomy to insert forceps
- mom may be fatigued and need assistance
vacuum assisted vaginal birth (5)
- attachment of vacuum cup to fetal head, using negative pressure to assist birth of head
- prereqs:
- vertex presentation
- ruptured membranes
- absence of CPD (cephalopelvicdisproportion, head is too big for pelvic inlet)
assessment after vacuum (2)
- assess baby head for caput succedicum (edema in the head that crosses the suture lines)
- assess for cephalohematoma (doesn’t cross suture so either L or R)
cesarean birth indications (6)
contributing factors
- fetal macrosomia
- ama
- obesity
- GDM
- multifetal pregnancy
- malpractice concerns
c-section birth (3)
additional factors
- elective c-section
- surgical tech: low transverse vertical incision
- complications and risks
VBAC (4)
- indications for primary c-section birth may be nonrecurring
- indiv decision based on risk factors from previous and current prey
- 9% women attempt TOL after c/s
- risk of injury greatest for fetus
DM: classifications (4)
-typical classification
: type I (more common in euro american and middle eastern ethnic), unknown trigger
: type II (highest pref in american indian youths), half with condition are undo
: impaired fasting glucose and impaired glucose tolerance (pre-diabetes)
-classification during pregnancy: gestational
GDM (8)
- glucose intolerance with onset or first recognition during pregnancy
- dx w/o pre-existing dx of diabetes
- begins in 2nd trimester and continues thru 3rd
- testing usually around 28 wk
- true GDM caused by placental secretion of enzymes that break down insulin, incr maternal adipose tissue, and inc insulin clearance by placenta
- 70% dx will get type 2 in 10 yrs
- lifestyle changes can delay or prevent type 2
- delivery is cure
