4

What some parental responses to fetal compromise?

Anxiety which is compounded by having to wait for results
Shock – most parents enter screening as though it is routine and are totally unprepared for a high risk result (Pilnik et al 2004) and unless diagnosis follows referral for a high risk screening result parents are unprepared for bad news
Poor growth does not normally suggest death to parent
Most women aren't expecting to see abnormalities in scan, focused on getting nice photos of baby
Scans seen as a way to see the fetus and even if possibility of Down’s syndrome is considered women rarely aware that other fetal problems or death may be detected, therefore profound shock
If pregnancy continues in the presence of high risk scores or diagnosis - prenatal grief
An ongoing pregnancy where the outcome is uncertain is stressful and can affect other children
Grief and loss if the pregnancy ends in TOP or IUD

5

What were the paternal responses in the (Locock and Alexander 2006) study?

Decision for screening often made without consulting partner although partner generally present at scan
Men felt they were bystanders – not offered a chair in scan. (Excluded from decisions legally)
Protector and supporter – assuming role of communicator if woman is distressed or deciders and enforcers once joint decision made
Gatherers and guardians of facts
Grieving parents

6

Breaking bad news

If the baby has a problem which may lead to TOP or early delivery with poor chances of survival the mother has to make a rapid decision
The person breaking the bad news must be aware of the clear meaning of any results and what options are available. The trust screening midwife and neonatologist/paediatrician/obstetrician may do this
The genetic counselling team may be involved

7

Fragmentation of birth

Referral to fetal medicine unit
Becoming high risk
Changing booking to a hospital with NICU/paediatric surgery
Termination? (Ground E, Abortion Act, 1967, TOPFA)
Who should co-ordinate this care?–Screening midwife?–ANC sister?–The lead midwife they already know?

8

What are some unexpected anomalies found at birth?

Even with new better scans some problems are missed, occasionally major ones
Most commonly discovered at birth are missing or extra digits and tiny cleft palates
Also anal atresia, tiny umbilical hernias and unclear genitalia may have been missed
Birth mark
