Conditions and assessments Flashcards
APH-
Assessment, referral + mgmt
APH : any PV bleed from 20wks (before onset of labour)
Assess
1) obs - assess harmodynamic stability
2) EBL (some may be concealed)
3) locate placenta (rule out placenta praevia)
4) palpitation- tender, tone, lie, contractions, movements, SF
measurement
5) CTG
Referral- Consult
Mgmt
1) stabilise woman- lay flat, Iv fluids, blood transfusion
2) site IV and take bloods (CBC, kleihaier, G+S, coag bloods)
3) do speculum

>37 wks
(70% women labour spontaneously by 24hrs)
MW role
*MW should assess all women to check maternal + fetal wellbeing (can be at home)
Assessment
* GBS risk factors (bacteriuria, previous GBS infected bbay, fever, GBS+ swab not ruled out by GBS- swab)
* liquor- colour, volume, smell
* obs (temp+ FHR)
* Palpation (tender?)
* Speculum (if unsure SROM)
* VE Contraindicated! (chorioamnionitis)
* FHR / movements / presentation
Mgmt + Referrals
moderate / thick Meconium - Consult (IOL)
Fever - Consult–> broad spctrum AB’s + IOL + NICu notified

- Monitor baby for GBS infection (RDS/ fever / signs of sepsis)
Meconium liquor (thick / moderate)
Risks / Mgmt / referrals
Risks
* mec may indicate baby is hypoxic
* baby may breathe in mec (mec aspiration syndrome) - interferes with nomral breathing- can lead to RDS/ infection / pneumothorax / persistent pulmonary hypertension
usually term babies
Mgmt
Consult (thick / moderate only)
CTG, IOL / prepare to suction non-vigours infant (not routine)
monitor baby for RDS, may develop into mec aspiration syndrome
Cord prolapse
definition/
definition
when loop of cord is alongside (occult- can’t be felt via VE) or past (overt- can be felt via VE) presenting part + membranes are rupture
Emergency- perinatal morbidity / mortality
Physiology
- cord presentation (umbilical cord sits between leading part and internal os, with membranes intact]
- when waters break, there is risk of cord prolapsing through cervix into vagina
- risk of fetal hypoxia with fetal weight on cord
**Risk factors **
ill-fitting presenting part ( malpresentation (e.g. footling breech) / unengaged / poorly applied )
ARM with unengaged presenting part- esp in presence of polyhydramnios
vaginal manipulation of fetus
external cephalic version
preterm
polyhydramnios
second twin
SIGNS
Difficult to predict impending cord prolapse (i.e. presentation)
abnormal FHR- early decels then prolonged decel/ bradycardia
**Referral- Emergency
**
mgmt
always check FHR before / after amniotomy + SROM
advise women with known risk of cord prolapse (e.g. malpresentation) to go to hospital if ROM
call for help
knees to chest / exaggerated SIMs
stop oxytocin (if running)
elevate presenting part (digitally or bladder filling)
Don’t touch cord (causes vasospasm)
Expedite birth (Vaginal if possible / caesarean - consider tocolysis)
Venous Thromboembolism
Physiology/ risks/ assessment /referrals/ prevention
**Physiology
**maternal body is “hypercoagulable” during pregnancy (esp end of pregnancy)
creates risk:
1) DVT- blood clots (thrombus) forms in deep veins
2) PE- thrombus can travel (embolus) to lungs and block blood to lungs
**Risk factors **
factors stopping circulation (C section / lack of mobilising)
smoking
>35 years
>
PPH >1L
Forceps
previous venous thromboembolism (CONSULT)
Assessment

Respiratory distress syndrome
what is it/ risks / signs / Referral / management
what is it
neonatal condition- usually preterm
caused by inadequate surfactant production (most surfactant produced after 30wks(
– surface tension in lungs is too high—> air sacs collapse on expiration —> increased WOB–> hypoxic / increased CO2
–> baby becomes fatigued, apnoic / hypoxic

Principles of bladder care
**labour
**PU 4hrly (with catheter if needed)
epidural- IDC, deflate IDC in 2nd stage (replace post birth)
instrumental- ensure bladder is empty
postnatal
*woman without IDC-
* void <6hrs, * 2 PU >200ml, * check bladder feels empty / flow + vol normal
woman with IDC
* keep IDC >6rs after epidural removed (confirm woman is mobilising )
* 1st void <6hrs after IDC removed, 2 voids >200ml
Rhesus negative women
what is the issue, risks (events), management, side effects
issue
some women have Rh Neg blood group- means they don’t have do Rh antigen on RBC’s.
most people DO have Rh antigen.
if maternal and (Rh pos) fetal blood mix, mum creates antibodies that “attack” fetal cells
Risks ( isoimmunising events)
* trauma (Car accident)
* ectopic pregnancy
* miscarriage >12wks (Anti D not required before then)
* stillbirth
* Amniocentesis / CVS
* APH

- <12 wkS 250 IU (only if there is repeated pain)
12-20 wks- 250 IU (No Kleihauer)
>20wks- request Kleihauer - use this to determine additional dose req)
Postnatal
- <12 wkS 250 IU (only if there is repeated pain)
- Confirm baby’s blood type + Coombs
- if baby is Pos- give mum 625 IU prophylactically

Diabetes - Type 1 + Type 2
BGL’s in pregnancy physiology of DM, Risks, Referral, management
physiology
DMT1- pancreas doesn’t make insulin, so BGL’s too high - requires exogenous insulin
autoimmune response
DMT2- body is less sensitive to insulin, and produces less
**BGL’s in pregnancy
**pregnancy hormone hPL reduces insulin sensitivity, so harder to maintain stable BGL’s
Risks

Describe the types of twins
physiology/ risk factors / timing of separation?
**Dizygotic (fraternal)
**2 ovum released. 2 sperm fertilise. 2 zygotes implant.
may share a placenta, but unlikely to have issues with vessels
DCDA - 2 Chorion +2 AMNION
share ~50% genetic material (same as non-identical siblings)- 50% same sex, 50% different
causes- IVF, maternal age (release more ovum naturally), familial
Monozygotic (identical)
1 ovum + 1 sperm = 1 zygote. zygote then separates to form 2 identical zygote. share 90% DNA- physically + psychologically very similar.
may share placenta / chorion/ amnion
- ~30% DCDA - separate placenta. split before 3 days (before placenta has formed)
- MCDA - share placenta +chorion, but separate amnion (3-9 days- before amnion formed)
- MCMA- share amnion (9-12 days)
- conjoined- >12 days
