Termination of Pregnancy

  • Accurate ultrasound assessment of the gestation of pregnancy must be made to guide management
  • Swab for Chlamydia, Gonococcus and bacterial vaginosis with high vaginal and endocervical swabs to prevent subsequence problems with infection
  • Blood group must be assessed to determine the need for ant-D prophylaxis
  • Contraceptive advice should be given

 

Medical termination

 

  • Antiprogesterone Mifepristone (allows uterus to become more responsive to prostaglandins) is given orally 36-48hr before insertion of a prostaglandin E1 analogue pessary. This is offered up to 9 weeks gestation and is normally 95% effective at inducing abortion
  • After 12 weeks synthetic prostaglandins are placed in the posterior vaginal fornix every 3 hours (max of 5 doses). In this case incomplete abortion is common and surgical evacuation is performed
  • When late terminations are performed intracardiac potassium chloride may be given to the fetus to arrest the heart before abortion

 

Surgical termination

 

  • Up to 12 week, the cervix is dilated and a suction curette is inserted to suck out the contents of the uterus
  • Beyond 12 weeks crushing of fetal parts may be required to allow removal (this has been almost totally superseded by medical termination in the 2nd trimester)
  • Prostaglandin preparation can be used to ripen the cervix before surgical termination to prevent the risk of trauma and to minimise blood loss
  • Complications of surgical termination, haemorrhage, infection and uterine perforation  

 

General complications

  • Infection – therefore screen for Chlamydia pre-operatively or give prophylactic antibiotics
  • Trauma – uterine perforation, cervical incompetence due to repeated procedures
  • Haemorrhage
