IFR consists of specific measures aimed to increase the delivery of oxygen to the placenta in order to alleviate or treat fetal hypoxia and acidosis.

IFR should be employed in those women who qualify for a Category 1 Caesarean section for fetal distress. It should not substantially delay delivery and should be instituted as arrangements continue to transfer the woman to theatre.

1)   The anaesthetist, obstetric team and the senior midwife should be alerted:

CATEGORY 1 Caesarean Section.

2)   Inform neonatology to attend.

3)   The woman should be examined to exclude hypotension, hypovolaemia and cord accident.

RESUSCITATE

4)   Any syntocinon infusion should be turned off.

5)   The woman should be placed in a left lateral position.

6)   Oxygen should ONLY be administered for maternal indication e.g. hypoxia / pre oxygenation – not routinely for IFR.

7)   1 litre of IV Compound Sodium Lactate should be run through (NOT if woman has pre- eclampsia or cardiac disease).

8)   If contracting consider Terbutaline 0.25mg subcutaneously from 0.5mg/ml ampoule dose of 0.25mg = 0.5ml. Contraindications include moderate/severe cardiac disease, hypovolaemia, abruption, maternal hypotension

TRANSFER

9)   The woman should be transferred to theatre as the IFR is proceeding.

REASSESS

10)   The fetal heart rate should be assessed continuously. The decision to deliver the baby or not should be made by a senior obstetrician. – decision on type of anaesthetic will be made in theatre depending on the response to IFR.

NOTE
If there are no contraindications to the use of propranolol a 1mg intravenous dose can be used to reverse the effects of terbutaline on the myometrium if required.
