10/13/2021 NURS 201 Maternal Child II Complicated Intrapartum Care 1 Augmentation of labor Stimulation of ineffective u/c, after labor has begun Pitocin admin most common Diluted in isotonic solution, runs as IVPB 30 u oxytocin in 500 mL NS 1 mu/min = 1 mL/hr Slow start, titrated to u/c and fetal response Maintained when active labor with effective u/c pattern No signs of hyperstimulation/tachysystole –review FHM baseline and throughout Review non-reassuring patterns of FHM – Chap 17 Other complications to monitor: Uterine rupture from stress/contractions Maternal water intoxication – oxytocin is antidiuretic Pitocin increases PPH risk 2 AROM Amniotomy/artificial rupture of membranes Risks Priority post-procedure interventions Cord prolapse – fetal heart FHM for reassuring pattern response? Assess fluid and document – color- Infection odor-amount Abruption – esp with Monitor temp q 2 hours polyhydramnios – rapid release Antibiotic for 18 + hr ROM Minimize upright/walking until head engaged Anticipate needs for abnormal fluid Blood – color, amount Meconium Thick or thin/particles Notify NB nurse, ped, team to anticipate deep suction at delivery 3 1 10/13/2021 Internal monitoring Fetal scalp electrode Accurate beat-to-beat variability Sterile technique – within RN scope Avoid sutures/fontanels Internal pressure catheter Accurate contraction strength MVU can be used to titrate Pitocin Minimize risk of uterine rupture May be used for amnioinfusion When much of amniotic fluid has been expelled – reduce dry/sticky/gacky cord compression 4 Version Changing fetal presentation to cephalic for delivery to prevent a c-section Approx 37 weeks ideal Breech, transverse, oblique presentations External manipulating fetus through relaxed belly/uterus, guided by US Internal Common with multi fetal Infant A born vag, cephalic; PCP can reach in and turn B 5 Version Contraindications Complications Unlikely to deliver vag Fetal distress Uterine malformations Cord entanglement into hypoxia Previous c-section Abruption CPD = cephalo-pelvic Rh sensitization disproportion Uterine rupture Placenta location/previa Induction of labor Oligohydramnios/ ROM Nuchal cord Uteroplacental insufficiency Presenting part already engaged 6 2 10/13/2021 Version Guided by US – AFV and cord location Tocolytic to relax uterus 0.25 mg terbutaline SC IV access, possibly epidural PCP pushes breech out of pelvis in roll RhoGAM post if mom Rh- Monitoring x 1-2 hours u/c and FHM, ROM Abrupt sharp or continuous pain may indicate abruption 7 Dysfunctional labor: Dystocia Difficult labor Ineffective dilation, effacement, descent FTP Commonly a problem/issue with the P’s – review from PN Powers Passenger Passage Position Psyche 8 Uterus: dystocia Hypotonic Hypertonic Too ineffective to produce cervical Uncoordinated and varying intensity change of u/c Exhausting Painful but ineffective More common during active phase More common in latent phase of labor At risk for fetal hypoxia and Augmentation abruption Possible epidural to relax Poor resting tone interrupts perfusion Risk factors Relief of pain for rest Multi fetal – overdistended uterus Risk factors Hypoglycemia Anxious primip; poor relaxation Cervix not ready/ripe 9 3 10/13/2021 Secondary powers/position/psyche Risk factors Providing assist Ineffective technique or position Help mom gain control Fear of injury or pain Empower to push effectively Absent urge to push Labor down before pushing Exhaustion Upright position as allowed Psychological Full concentration of push effort with contractions, not between 10 Passenger/s Macrosomic size/LGA CPD – rough estimate head to pelvis Shoulder dystocia risks Risk for assisted delivery Forcep, vacuum, extended episiotomy Malpresentation OP = occiput posterior OT = occiput transverse Face presentation Breech Multi fetal Anomalies 11 Spinningbabies.com https://youtu.be/F3iqUUJUvw https://youtu.be/F3iqUUJUvw8 12 4 10/13/2021 Dystocia: precipitous delivery Labor < 3 hours Numerous risk factors Interventions Delivery tray/ go-bag – sterile and mobile At bedside – coach and support Thorough assess/history of labor start and progression Complications Uterine rupture Fetal hypoxia Postpartum hemorrhage Lacerations – canal/peri Amniotic fluid embolism 13 Premature rupture of membranes PROM: spontaneous rupture before start of labor, u/c Risk factors: Infection Weak membrane/sac Incompetent cervix Complications Infection Preterm delivery Cord prolapse/compression 14 PROM s/s Pooling of fluid in vaginal vault, drip down leg/s Nitrazine tape, ferning test Amnisure swab to confirm – 15 minute Assess fluid – color, odor, amount VS, FHT – what FHM indicates infection? Vag exam dependent on gestational age Speculum exam by PCP can ID fluid in vault, cervix status Management based on gestational age Pelvic rest, no nipple stim, activity restriction Allow labor if near term (34-36 weeks) , fetal lungs are ready PPROM = preterm, premature ROM Antibiotics – Ampicillin, Amoxicillin, Azithromycin IV x 48 hours, oral x 5 days 15 5 10/13/2021 Preterm labor Weeks 20-37; INFECTION primary risk – good health promotion Very – moderately – late preterm s/s u/c > 10 minutes, 30 sec + duration Cervical change: 1 cm, effacement Painful or painless Abdominal cramp with or without diarrhea Low back pain, suprapubic pain Pelvic pressure Discharge –bloody show, red, brown, clear, mucous plug ROM 16 Preterm labor Interventions Speculum exams to ID rupture, cervix status US to help ID cause Fetal fibronectin – swab at cervix can ID proteins that indicate labor with 2 weeks Bedrest, activity restrictions Tocolytics Terbutaline- SC q 4 hours HOLD for tachycardia > 120 bpm Indomethacin, Sulindac – inhibit prostaglandin Nifedipine – CCB MgS04 – relaxes smooth muscle/uterine 17 18 6 10/13/2021 19 Fetal lung development for preterm Admin at least 24 hours before delivery Betamethasone 12 mg: two IM doses, 24 hours apart Dexamethasone 6 mg: four IM doses, 12 hours apart SE Glucose intolerance Temporary increase in leukocytes Insomnia Irritable – ‘roid rage’ Increase risk infection /mom 20 Prolonged pregnancy Postdate = >42 weeks Complications Aging placenta = uteroplacental insufficiency Fetal distress Oligohydramnios with aging = cord compression risk Meconium in utero = aspiration risk and resp distress, pneumonia If placenta healthy, fetus continues growth = dysfunctional labor L/D trauma Postpartum hemorrhage (PPH) risk Maternal fatigue and exhaustion 21 7 10/13/2021 Prolapsed cord Umbilical cord displaced between presenting part and the anmion or is protruding through the cervix Results in cord compression and hypoxia s/s Cord observed at peri – potentially Mom reports ‘something coming out’ FHT bradycardic with variable decels Fetus very active, then minimal variability Risk factors Hydramnios (poly) Small fetus Fetus station high (-2 to -3) – review from PN 22 Variable decelerations 23 24 8 10/13/2021 Cord prolapse actions Relieve cord pressure Position Knee-chest, Sims, Trendelenberg Sterile glove Support head /presenting part off of cord FHM continuous 02 face mask Prepare for assisted delivery/c-section 25 Uterine rupture Separation of the uterine tissue due to a tear in the wall, caused by contractions Complete = direct communication into peritoneal cavity Incomplete = rupture into peritoneum covering the uterus but not into peritoneal cavity Risk factors Previous uterine surgery, c-section Hydramnios (poly) Multi fetal – overdistention Abdominal trauma Multi –para/gravid Hyperstimulation of uterus during labor 26 Uterine rupture s/s Actions Abdominal tenderness or severe pain CV STABILIZATION Chest pain, pain between scapula, C-section may save fetus if rapid inspirational pain enough Hypovolemic shock High potential for hysterectomy Hidden hemorrhage into peritoneum Small rupture may be repaired Fetal distress – what FHM would you expect?
