A

34
Q

Possible perceived benefits of a medical abortion

A

Avoids need for surgery
Avoids an anaesthetic
The woman is awake and aware of the process which may enable them a sense of control
May feel more of a natural process than surgery to some women
Depending on gestation may be able to pass products at home
If performed in a clinic/ hospital = day case
May be considered more private
May be able to be accompanied

35
Q

Possible perceived benefits of a surgical abortion

A

Can be performed under anesthetic or sedation
Avoids the woman seeing the pregnancy unless she requests to
Quick - Usually day case + home the same day
Usually reduced days of bleeding
May reduce duration and severity of cramping pain
Timing and duration is fixed
Can have contraception started / fitted at time of surgery
may require less repeat attendances

36
Q

Possible perceived disadvantages of a surgical abortion

A

The woman will usually need
someone to accompany her home - if she
had sedation or GA
Overnight stay may be required
Must occur in hospital / clinic setting
Includes risks of uterine perforation or injury to the cervix
May be considered less private as requires more staff to be present
Usually cannot be accompanied during the procedure

37
Q

Possible perceived disadvantages of a medical abortion

A

Increased pain and bleeding amount and duration
Timeframe for completing the abortion is more unpredictable
May require a follow up pregnancy test or ultrasound
May require more return visits than a surgical procedure
Can see the passage of blood and POC
Risk of uterine rupture if previous CS
Cannot have IUS / IUD inserted immediately if completed at home

38
Q

What additional information may be needed for a woman having a termination because of fetal anomaly?

A

May be provided in the maternity setting or need referral to a separate termination service.
Confirm they have sufficient information about the anomaly
Explain that the fetus may not look abnormal despite there being a fetal anomaly

39
Q

What other agencies should a TOP service have links with

A 
gynaecology / EPAU for non-vibiable IUP or ectopic
AN services
Social care
Adult safeguarding
Child safeguarding
DV support
Sexual abuse support
Alcohol and drug support
community SRH
GUM
40
Q

What are the grounds for abortion

A-G

A

A - continuance of the pregnancy would involve risk to the life of the pregnant woman greater than termination

B - termination necessary to prevent grave permanent injury to the physical or mental health of the pregnant woman

C - pregnancy not >24 weeks and continuance would involve risk, greater than termination, of injury to physical / mental health of the woman

D - pregnancy not >24 weeks and continuance o would involve risk, greater than termination, of injury to the physical / mental health of any existing child(ren) of the family of the pregnant woman

E - a substantial risk that if the child were born it would suffer from such physical or mental abnormalities as to be seriously handicapped:

In an emergency if a termination is immediately necessary:
F - to save the life of the pregnant woman
G - to prevent grave permanent injury to the physical or mental health of the pregnant woman

41
Q

WHO definition of unsafe abortion

A

WHO defines unsafe abortion as

“a procedure for terminating an unintended pregnancy carried out either by persons lacking the necessary skills or in an environment that does not conform to minimal medical standards, or both”.

42
Q

Risk of continuing pregnancy after surgical abortion

A

Continuing pregnancy after surgical abortion occurs in

0.2% of procedures at 12 weeks or less.

43
Q

What factors may increase the risk of an ongoing pregnancy after surgical termination?

A 
Procedure in a multiparous woman
Conducted at six weeks’ gestation or less, 
When small suction cannulae are used, 
Performed by inexperienced surgeons 
Women with uterine abnormalities
44
Q

Risk of continuing pregnancy after medical abortion

A

ongoing pregnancy rate for early medical abortion with recommended mifepristone-misoprostol regimens is
0.5 - 0.7%

More common with oral or lower doses of misoprostol.

vacuum aspiration is the treatment of choice because another dose of misoprostol is effective in <40%
