questions 3 Flashcards
Definition of APH
Any bleeding
>20 wks
>before onset of labour
fetal fibronectin
what is it
when do we test
indications
glycoprotein found at maternal-fetal membrane
normally found at low levels- higher levels may indicate increased risk of preterm labour
used bewteen 26-34wks
Indications
- intact membranes
- cervix <3cm
- only slight PV bleeding
- no cervical cerclage
- no sex / pelvic exam in last 24hrs
not appropriate if woman is asymptomatic (even if she is considered high risk)
IOL contraindications
any maternal/fetal condition not to birth vaginally
malpresentation - transverse/ oblique
classical CS
Cord prolapse
Active herpes
placenta praevia
absolute cephalopelvic disproportion
invasive carcinoma of cervix
baby is severely compromised
relative CI’s
- FHR is non reassuring
- breech
- polyhydramnios
- not engaged
- severe hypertension
- maternal heart disease
cord presentation:
- cord is inbetween leading part of fetus, and internal os AND membranes are intact
- diagnosis may be identified via VE and colour doppler studies
- high risk of cord prolapse, if membranes break
occult cord
- cord is alongside presenting part
- not identified via VE
Cord prolapse- overt
-Membranes ruptured +- cord descends past fetal presenting part, through cervix into vagina
- diagnosis
* -visual (seen in introitus)
* palpation in vagina
* Abnormal FHR
- high risk of fetal hypoxia
cord prolapse- occult
-membranes ruptured
-cord is trapped between presenting part and pelvis
diagnosis
* FHR change
* rarely seen / felt
cord presentation / prolapse
risk factors
general
- multiparous
- small baby (preterm / SGA)
- abnormalities
- malpresentation (breech, transverse/ oblique /unstable)
- second twin
- polyhydramnios
- unengaged presenting part
- abnormal placenta (e.g. low lying)
intervention related
ARM
ECV / Vaginal manipulation of baby after ARM
Referral for cord presentation + prolapse
Emergency
cord prolapse - mgmt
1) change woman’s position (exaggerated SIMs)
2) call for help
3) confirm FHR viability
4) minimise compression bewteen fetal head and pelvis
* digital pressure via VE
* bladder fillling
5) Expedite birth (CS unless birth imminent)
give oxygen + IV line
consider tocolytics
*avoid handling cord / exposing cord to cool air to avoid vasospam of cord vessels
Insulin mechanism
insulin unlocks glucose transporters (passive transport)
for women already with diabetes and on insulin, what changes to diet can they expect
may become more restrictive
what is HbA1c, when do you refer
universal sreening <20wks
looks at average glucose in blood over last 4-6wks
<40 “ NORMAL”–> polycose at 24-28 wks
41-50–> “prediabetic” clinic + OGTT at 24-28wks
>50- ->”probable diabetes”
polycose test-
indication / normal results
for women with normal HbA1c
1hr 50g glucose
<7.8 NORMAL
>7.8 -11.0 -> do OGTT
»11.0–> refer to clinic
OGTT
indication / what is it/diagnostic results
only for high risk women
- women with high polycost tet results

Shoulder dystocia-
definition
Definition
A birth that requires additional manoeuvres to release the shoulders after
* head has been born
* AND routine axial traction has failed
shoulder dystocia- describe the cause
disproportion between
-bisacromial diameter of fetus (width of shoulders)
Anterio posterior diameter of pelvic INLET
Shoulder is impacted
- usually anterior shoulder is impacted behind Symphysis pubis
- occasionally posterior shoulder is impacted against sacral promontory
Clinical signs of shoulder dystocia
- prolonged 2nd stage
- slow descent of fetal head
- slow extension of head with chin remaining tight against perineum
- absence of restitution
```
~~~
what is referral for shoulder dystocia
Emergency
Describe process to respond to Shoulder dystocia
What are key considerations if shoulder dystocia has been diagnosed
1) CALL FOR HELP (always first) - Emergency
- discourage pushing
- avoid excessive traction
- prepare for emergenices: NB resus + PPH
2) POSITION- McRoberts ( to increase functional size of bony pelvis + dislodge shoulder)
3) Suprapubic Pressure (to reduce bisacromial diameter, move shoulder into wide oblique diameter)
4) Internal manouvres
(change relationship of bisacromial diameter + bony pelvis) - posterior arm removal / auxillary traction
McRoberts manouvre
indication
purpose
describe position
indication-
- shoulder dystocia- first position change - resolves up to 40%
position-
- Completely Flat (no pillows under head / back)
- knees to shoulders /nipples
purpose
flatten lumbosacral spine
raise the symphysis pubis
-
Suprapubic Pressure
indication
purpose
describe position
indication-
shoulder dystocia- after + with McRoberts
purpose-
put pressure on posterior aspect of impacted shoulder
* to ADDUCT shoulders- and thus reduce the bisacromial diameter of fetus (width of shoulders)
* to encourage rotation of anterior fetal shoulder into wider oblique diameter
position
- stand SAME Side as fetal back
- apply pressure ABOVE symphysis pubis
- CPR hands- rocking or constant pressure
- simultaneously, another MW can apply gentle axial traction
PV internal manoeuvres
indication
purpose
describe
indication
Shoulder dystocia
- use after trying position + suprapubic pressure
purpose
change relationship of bisacromial diameter (shouder width) with bony pelvis (i.e. rotate)
Describe
- communicate + get consent
- try internal rotation (two fingers) –> wood screw (2 hands, 2 fingers)–> delivery of posterior arm (whole hand)
PV internal manoeuvre- remove posterior arm
indication
shoulder dystocia
try these if internal rotation / wood screw manouvres haven’t worked
purpose
reduce bisacromial diameter (by width of arm)
description
insert whole hand posterior to baby
try to find hand and grasp out- may need to push down on cubital cossa (elbow) to flex, encouraging arm to sweep over baby’s chest
p. 953
remember- discourage pushing, and never grasp / pull fetal head
PV internal manouvre- internal rotation
purpose
shoulder dystocia
comes after position + suprapubic pressure
try this internal manouvre first
description
insert 2 fingers
apply pressure to anterior fetal shoulder (adduction) to encourate rotation into oblique plain / under symphysis
remember- discourage pushing, and never grasp / pull fetal head
PV internal manouvre- wood screw manoeuvre
purpose
shoulder dystocia
comes after position / suprapubic pressure
try after internal rotation manouvre
description
ONLY manouvre with 2 hands
2 fingers of each hand-
involves internal rotation (pressure on anterior fetal shoulder , as well as on anterior aspect of posterior shoulder too)
Anthropoid pelvis-
describe shape
what is it associated with?
shape- oval with longest anterior posterior diameter. larger pelvis generally
posterior position
- It is believed that the exaggerated lithotomy position (McRoberts manoeuvre) facilitates delivery of the foetal shoulders through which of the following mechanisms? Choose one answer.
a. Rotating the symphysis pubis to free the impacted shoulder

what are risks to formula feeding
obesity
DM
Cholestasis
signs / assessment
cause
risks in pregnacy
mgmt
signs
- pruritus in absence of skin rash
- AND abnormal Lft +/or raised bile acids
- both have no alternative cause + resolve after delivery
may also have - pale stools/ dark urine/ possible jaundice
cause
multifactorial- genetic, environmental, increased oestrogen
Risks
preterm birth, stillbirth, meconium
Assessment
- inspect skin- ensure it’s not ezema, PUPP
- bloods- ALT AST, bilirubin, bile salts
mgmt
close monitoring
IOL
recheck LFT’s 10 days post partum (LFTs normally increase in first 10 days)
feeding multiples- esp if twin has dropped 8%
body should be able to produce double breastmilk
may be easier to breastfeed together (1 breast helps other breast let down) or separately (less awkward)
<10% is normal weight loss.

listeria
what is it
symptoms
AN risks
what can it pass through
key safety messages
symptoms
non-specific- usually asymptomatic- accurate diagnosis difficult. minor illness in pregancy doesn’t warrant AB’s for listeria
may develop 2mths after expsoure
Risks to baby
PPROM, fetal distress, PTL, chorioamnionitis, placental abruption, fetal demise, sepsis, stillbirth
can pass Pass through placenta / vagina
safety
- cook food well, eat steaming hot
-avoid high risk foods (Raw eggs, unpasteurised cheese, unhomogenised milk, uncooked seafood, meat)
Rubella
what is it
screening
mgmt
what is it**
Virus - passes to baby invitro.
if contracted in Trimester 1, ** can cause congenital Rubella syndrome (blindness, heart, stillbirth(
screening
- universal screening- check bloods (gold/ red) for presence of antibodies (10 indicates immunity)
If NOT immune-
- avoid contact with people at risk of rubella (flu like symptoms, rash)
- have vaccination post birth (NO VACCINE IN PREGNANCY)
- if suspected rubella contraction- CONSULT
what are the types of immunity
1) innate
** (what you are born with- e.g. skin)
2) **Acquired (What you develop in your lief)
i) Active
(your body developed immunity in response to something)
* ` Natural - body developed immunity in response to infection (e.g. chicken
pox)
* Artificial- body developed immunity in response to vaccine (Covid/ Rubella)
ii) Passive (body developed immunity after receiving antibodies from something)
* Natural- antibodies received from mother(e.g. breastmilk, placenta)
* Artifical- Antibodies recived from a medicine- e.g. Anti D immunoglobulin
- What type of immunity is transferred from mother to child by IgA immunoglobulins? Choose one answer.
a. acquired passive
b. natural active
c. acquired active
d. natural passive
Passive (body received the AB’s, rather than making them)
natural (from mum, rather than medicine)
