Post-partum Care & Emergency Obstetrics Flashcards
What do we call the first 6 wks following delivery?
The Peurperium
Who sees the mother during the Peurperium? [2]
Midwife for the 1st 9-10 days
Then Health Visitor
Go to GP for 6wk postnatal check
What do the midwife and health visitor do when seeing the new mum? [3]
Observe for signs of abnormal bleeding and infection (wound, breast or endometritis)
Debrief the events of the birth especially if there was an emergency CS
Also discussing family planning
What are the common and fairly normal problems in the Peurperium? [3]
- Feeding problems
- Bonding issues
- Social problems e.g. the partner, other children or financial
What are the major dangers to the mother in the Post-partum period? [5]
Post-Partum Haemorrhage VTE Sepsis Post-natal Hypertensive disorders Psychiatric Disorders
What are the types of PPH? How are they distinguished [2]
Primary - >500ml within 24hrs
Secondary = >500ml after 24 hrs to the 6wk boundary
What causes primary PPH? [4]
Tone - e.g. Atonic Uterus
Trauma - e.g. tears or ruptures
Tissue - Retained
Thrombin - e.g. can’t clot
What causes secondary PPH? [3]
Retained Tissue
Endometritis
Tears/trauma
How do we reduce risk of a VTE? [2]
How might a VTE present in the Peurperium [3]
A proper risk assessment and if necessary thromboprophylaxis
Presentation
- Unilateral Leg Swelling and/or pain
- SOB or Chest pain
- Unexplained Tachycardia
How can we test for a VTE? [3]
What test do we normally use that cannot be used in pregnant women - state why
ECG
Doppler US
CXR +/- VQ scan
D-dimer isn’t useful in pregnant or post-partum women because they’re already hypercoagulable
How do we treat a VTE in pregnancy? What VTE treatment is contraindicated pregnancy but can be given in breastfeeding
LMWH
Warfarin can be used when breastfeeding but not during pregnancy
Sepsis is the leading cause of direct maternal death in the UK, how do we test for it if suspicious? [4]
Blood Culture
MSSU
Wound Swab
Lower Vaginal Swab (LVS)
How do we manage a suspected case of post-partum sepsis? [4]
- Promopt IV abx
- Antipyretics
- IV fluids
- Refer to hospital
What are the major psych disorders in post-partum women? [3]
- Baby blues
- Postnatal Depression
- Peurperal Psychosis
What is the baby blues caused by?
Typical onset?
Natural history?
Hormonal changes cause the blues in many mothers 1-3 days PN.
Doesn’t affect function and doesn’t require treatment
What is postnatal depression?
It does require specific treatment unlike baby blues [2]
Classic depressive symptoms that do affect function and bonding
Look for a history or family history of affective disorder
How do we handle Peurperal Psychosis? [2]
What to look for?
Much more serious, women can be a danger to themselves and babies.
So inpatient psych care is required
Look for a history/FH of affective disorder, bipolar or pyschosis
Lochia
What is it?
When should it stop?
What to do if it doesn’t stop?
- Passage of blood
- Mucous and tissue
- Occurs during childbirth
- Expect to cease 4-6w
- Continued vaginal discharge after 6w could indicate retained POC
- Do USS in this case
Breastfeeding contraindications [2] Drugs unsafe in pregnancy: Antibiotics [4] Psychiatric drugs [2] Antiplatelets [1] Endocrine [2] DMARDs [2] Anti-arrhythmic [1]
HIV
Galactosaemia - baby unable to metabolism galactose
- Antibiotics: ciprofloxacin, tetracycline, chloramphenicol, sulphonamides
- Psychiatric drugs: lithium, benzodiazepines
- Anti-platelet: aspirin
- Endocrine: carbimazole, sulphonylureas
- DMARDs: methotrexate, cytotoxics
- Anti-arrhythmic: amiodarone
Amniotic fluid embolism Presentation [3] Ax [2] Complication Mx
Presentation:
- Can occur suddenly during L&D
- Sudden development of acute respiratory distress and cardiovascular collapse
- In a patient in labour or who has recently delivered
Ax: amniotic fluid enters maternal circulation, triggering syndrome similar to anaphylaxis and septic shock
Cx: DIC
Mx: effective resus
Cord prolapse Ax Px [2] Signs and symptoms [3] Prognosis
Ax: umbilical cord descends ahead of presenting part of fetus
Px: leads to cord compression and cord spasm leading to fetal hypoxia and irreversible damage or death
Sy/Si:
- abnormal fetal HR
- cord palpable vaginally
- cord visible beyond level of introitus
Pro: if treated early fetal mortality LOW
Cord prolapse
Risk factors [7]
Risk factors:
- artificial rupture of membranes, prematurity
- multiparity, polyhydramnios, twins
- cephalopelvic disproportion
- abnormal presentations (especially transverse lie)
- placenta praevia
- long umbilical cord
- high fetal station
Cord prolapse Management [5]
Management:
• Elevate presenting part of fetus: catheterise and fill bladder
• Tocolytics
• Push cord into vagina: (NOT to uterus) to keep warm
• Maternal position: onto all fours
• Delivery: immediate CS (if fully dilated and head low can do instrumental delivery)
Placenta accreta
Ax [3]
RF [3]
Mx
Px: - Attachment of placenta to myometrium due to defective decidua basalis - placenta doesnt separate properly - leading to PPH risk RF: - previous CS, placenta praevia, PID Definitive mx is hysterectomy
Shoulder dystocia
Ax
Px
Complications [4]
Inability to deliver body of fetus using gentle downward traction but head is already delivered
- Impaction of anterior shoulder on maternal pubic symphysis
Complications:
- PPH
- Perineal tears
- Brachial plexus injury
- Neonatal death (asphyxiation)
Shoulder dystocia
Risk factors [3]
Mx [3]
Risk factors:
- Macrosomia, high maternal BMI, DM
- Prolonged labour
- Assisted vaginal delivery
Mx:
- Call for senior help: obstetrician, pediatrician, anaesthetist
- McRoberts manoeuvre
- Generous episiotomy
PPH risk factors
What is one complication of PPH?
Previous PPH Prolonged labour Pre-eclampsia Advanced maternal age Polyhydramnios Emergency CS Placenta praevia, accreta Macrosomia Ritrodrine (tocolytic)
Cx: Sheehan’s syndrome
PPH management
Immediate [4]
Medical mx 3 options
Surgical options [4]
ABCDE Peripheral 14G cannula Bimanual uterine compression to stimulate contractions Initial medical mx - IV syntocinon 10 units - OR IV ergometrine 500mcg - OR IM carboprost
Intrauterine balloon tamponade
B-Lynch suture
UAE
Hysterectomy in severe uncontrolled hemorrhage
