ensure woman stable and check no POC (products of conception) coming from os

if shock out of proportion with volume of bleeding, consider rare possibility of uterine rupture (rare in first trimester, uncommon but possible later) and check from scan this was definitely intrauterine pregnancy and not ruptured ectopic

A
  • A: continuance of pregnancy would involve risk to life of pregnant woman greater than if pregnancy terminated

29
Q

What is the guidance about surgical termination of pregnancy before 7 weeks?

A

conventional suction termination should be avoided

30
Q

What is the guidance about surgical TOP for 7-13 weeks gestation?

A

conventional suction termination appropriate, but in some settings skill and experience of practitioner may make medical TOP more appropriate at gestations >12 weeks

31
Q

What is the recommendation for surgical TOP at gestation >13 weeks?

A

dilatation and evacuation following cervical preparation should be performed

32
Q

What is needed to perform dilatation and evacuation for TOP at >13 weeks?

A

requires skilled practitioners with necessary instruments and sufficiently large case load to maintain skills

33
Q

What factor increases the risks of dilataiton and evacuation for TOP and what are the risks (3)?

A
  • greater gestation
  1. bleeding
  2. incomplete evacuation
  3. perforation
34
Q

What are 2 reasons why cervical preparation before dilatation and evacuation for TOP is highly beneficial?

A
  1. Reduces difficulties with cervical dilatation
  2. Particularly if patient <18 years or gestation is >10 weeks
35
Q

What are 3 possible regimes to achieve cervical preparation in advance of surgical dilatation and evacuation for TOP?

A
  1. Misprostol 400mcg PV 3h prior to surgery

mifepristone priming plus prostaglandin regime most effective

mifepristone PO then misoprostol PV 48hr later

medical TOP appropriate, safe and effective alternative to surgery (incomplete procedure rates increase after 9 weeks)

39
Q

What is the suggested management for TOP at 13-24 weeks gestation?

A

medical TOP appropriate and safe in this group

40
Q

What is generally considered about the method of TOP in advanced gestations i.e. >24 weeks?

feticide should be considered

41
Q

How can the medical management of TOP be broken down in gestation ranges?

prostaglandin E1 analogue used off-licence in medical TOP and for cervical preparation prior to surgical TOP

stimaulates uterine contractions
