According to NICE ( Intrapartum care for healthy
women and babies )

• Check blood pressure every 5 minutes for 15 minutes during
  establishment or after further boluses
• Check sensory block hourly
•  Continuous electronic fetal monitoring for 30 minutes during
  establishment or after boluses of 10 ml or more
• Intravenous access should be established prior to commencing regional analgesia.
• Do not administer routine preloading and maintenance fluid

Conversion from LMWH back to warfarin should be delayed for at least 5 to 7 days after delivery
to minimise the risk of haemorrhage during the period of overlap of LMWH and warfarin treatment.

• People who experience fertility problems should be offered counselling because
  fertility problems themselves, and the investigation and treatment of fertility
  problems, can cause psychological stress.
• Counselling should be offered before, during and after investigation and
  treatment, irrespective of the outcome of these procedures.
• Counselling should be provided by someone who is not directly involved in the
  management of the individual's and/or couple's fertility problems.
