Complications in Labour and Delivery
- Dystocia
- Preciptious labour and delivery
- Malpresentation/ Position
- POP
- Breech and ECV
- Operative and assisted deliveries
- Caesarean birth
- Forceps/ Vaccuum
- TOLAC/ VBAC
- Obstetrical emergencies
- Shoulder dystocia
- Cord prolapse
Dystocia
- Abnormal or difficult labour
-
Problems with powers
- Hypotonic or hypertonic uterine contraction
- Arrested labour
- Preciptious labour (<3 hours)
-
Problems with Passenger
- POP
- CPD
- Breach
- Shoulder systocia
- Cord prolapse
- May result in
-
Operative delivery
- Forceps, vacuum, c-section
-
Operative delivery
Breach Presentation
- 3 to 4% of all term pregnancies
- Frank
- 50 to 70%
- Footling
- 10 to 30%
- Complete
- 5 to 10%
- Frank
Diagnosis of Breech
- Maternal
- Leopold’s Maneuver’s
- FH auscultated above umbilicus
- Vaginal examination
- Ultrasound
- Meconium (if ROM)
Fetal Risks
- Cord prolapse more likely with ROM
- Traumatic injury to the aftercomin head can → intracranial hemorrhage of anoxia
- Preterm breech: Footlin and body may deliver before full dilation → entrapment
2009 SOGC - Vaginal Delivery of Breech
- Vaginal delivery os the best method of delivering an uncompliated term, frank, of complete breech, singleton, ?35oo and <4000g with flexed ehad
External Cephalic Version
- Ultrasound
- Reactive NST
- Can’t be engaged
- Tocolytic to relax uterus
- Risk of nuchal cord
- Fetal monitoring
- Monitor for SOL
Types of Operative Delivery
- Cesarean birth
- Operative vaginal delivery
- Forceps
- Vaccum
Indications for C-Section
- Can be planned or unplanned
- Non-reassuring fetal heart rate findings
- Active genital herpes
- Multiple gestation (three or more fetuses)
- Umbilical ccord prolapse
- Pelvic size (tumors that obstruct birth canl, cephalopelvic disproprotion_
- Lack of labour prgression/ failed induction
- Maternal infection/ severe disease
- Placenta previa
- Previous cesarean section (relative)
- Fetal anomalies or extremes in size (low, high)
C-Section Incision
- Transverse in lower segment
- Vertical in lower segment
- Classical incsision: in body of the uterus
- Wounds are closed based on physican specific
- Important to look at the incision before sending someone home
- Usually take out incision on post-op day 5
- Can be doen at home by healthy-and-home or got ot their physicians office
Women who have C-Section are at Increased Risk For:
-
Intra-Opeative
- Aspiration
- Difficult airway managment
- PPH (>100 mls)
-
Post-Op
- Endometritis/ Infection
- Hemorrhage
- Poor bladder emptying
- Paralytic ileus (rare)
- Thrombophlebitis
Preparation in C-Section
- Cesarean birth requires
- Establishing IV lines
- Placing indwelling catheter
- Performing abdominal prep
- Ranitidine or sodium citrate
- NICU
- Teaching Needs Include
- What to expect before, during, and after delivery
- Why is it being done
- What sensations will the woman experience
- role of significant other
- Interaction with newborn
Post-op/Post partum
- Pain
- Analgesia/ antiemetic. antipruritic
- Naproxen PRN for vaginal delivery
- C-Section: Naproxen is scheduled for first 24 hours and then PRN
- Comfort measures
- Assess fro hemmorhage
- Assess for infection
- Get her MOVING
- Postpartuma nd postoperative checks
- Fatigue: Different for scheduled vs. non-scheduled c-section
- Attention to fatigue
Trial Of Labour After Cesarean Section (TOLAC)
- Depends on indication and type of 1st section, maternal health
- Most common risks:
- Hemorrhage
- Uterine rupture - Complete separation of the myometrium with/ without extrusion of fetal parts into the maternal peritoneal cavity
- Infant death or neurological complications
- Successful TOLAC becomes VBAC
- Fetal monitoring
- Avoid cervical ripening
- Need to be papered for c-section quickly if things go wrong
Operative Vaginal Birth: Indications
- Fetal indications
- Non-assuring fetal heart rate
- Maternal
- Exhaustion or inability to push
- Lack of rotation
- Maternal disease
Operative Vaginal Birth: Intervnetion During
- Support and educate
- Fetal heart assessment
How can we prevent operative vaginal birth?
- Support throughout labour
- Mobility
- Positionc hanges
- Rest
- Keep bladder empty
- Well hydrated and nourished
Important Considerations in Forceps/ Vaccuum
- Need to be completely dilated/ membranes ruptured
- Empty bladder
- May need an in-and-out catheter
- Fetal position known/ adequate pelvis
- Analgesia if able
- If it is a failed forceps and vacuum = C-section
Forceps
- Applied by a physician
- Downward pressure and then upward once the larges part of the head has come through
- Would be done while a women is pushing
- Fetal scalp is visible- presenting part is 2+- head is clearly engaged
Vacuum Extractor
- Suction applied to fetal head (occiput)
- Should be progressive descent with first two pulls (with contractions) Used during contractions and pushing
- Geneally would not do more than 3 pulls
Complications with Operative Vaginal Births: Newborn
- Common
- Bruising
- Laceration
- Edema
- Uncommon
- Renal hemorrhages
- Nerve injury
- Cephallhematoma
- Cerebreal hemorrahge
- Skull fracture (forceps)
- Intracranial bleeding, subgaleal hemorrhage (vaccuum)
- Watch for hyperbilirubinemia
Complications with Operative Vaginal Births: Woman
- Genital tract trauma
- Increased bleeding
- Risk for PPH
- Bruising and edema
- Shoulder dystocia
Nursing Care During
- Attention to bladder
- Assessment of fetal well being throuhout
- Documentation
- Ease of application
- Timeon, off, number of pulls
- Difficulties suchas pop-offs
Nursing Care After
- Maternal
- PPH: Lacerations, atony
- Analgesia
- Watch for hematome
- Neonatal
- Trauma/ injuries
- Jaundice
Shoulder Dystocia
- Anterior shoulder impacts against maternal symphysis pubis
- Fetal shoulder do not deliver spontaneously
- Failure to deliver with expulsive effort and usual maneuvers
Major Risk Factors for Should Dystocia
- Maternal obesity
- Macrosomic infant
- Hisotry where a baby had should dystocia
- If you can mange diabetes = less risk
- Non-Diabetic
- babies >4000 gms 4%
- babies >4500 gms 10%
- Diabetic:
- babies over 4000 gms 15%
- babies >4500 gms 42%
- Non-Diabetic
Turtle Sign
- Nuco-cord x3- risk- cord around the neck and quite tight
- Turtle sign is a heralding sign of shoulder dystocia
Shoulder Dystocia: ALARER
- Ask for help
- Lift / hyperflex legs
- Anterior shoulder disimpaction
- Rotate posterior shoulder
- Manual removal of posterior arm
- Episiotomy
- Roll over onto ‘all fours’
- Do not see often
McRobert’s Manoeuvre
- Before McRoberts Positioning: Diagonal orientation of symphysis makes shoulder delivery difficult
- McRobert’s Maneuver: Pelvis tilts, orienting symphysis more horizontally to facilitate should delivery; looks like knees to ears
Suprapubic Pressure
- NOT fundal pressure
- Lateral pressure in direction of fetal nose
- Protect your back
- Support/ inform patient and support person
Shoulder Dystocia Complications: Maternal
- Episotomy
- Extended lacerations
- Hematomas
- Uterine atony
- Hemorrhage
- Bladder injury
- Rectal injury
Shoulder Dystocia Complications: Fetal
- Number of clavical or humerus
- Brachial plexus injury or spinal nerve damage
- Erb’s palsy
- Asphyxia
- Death
Cord Prolapse
- Obstetrical emergency
- Sudden, severe, variable decelerations or no fetal heart
- Feel or see cord
Cuases of Cord Prolapse
- Polyhydramnios
- Long cord
- Malpresnetation (breech, transverse)
- Premature rupture of membranes
- Amniotomy before engaged vertex
Obsterical Emergency
- Precaution - Always check fetal heart after ROM!!
- Get help, Prepare for Cesarean section delivery
- Keep pressure (presenting part) OFF cord
- Trendelnburg, Knee-chest position
- Keep hand in vagina
- ↓ contractions if able
- Warm wet sterile cloth if outside vagina
- Vaginal delivery only if fully dilated
