Abstract
All rhesus-negative women who completed a pregnancy between January and August 1992 in two Scottish regions were studied to assess whether the administration of the rhesus prevention programme was complete: 671 rhesus positive (or rhesus type unknown) pregnancies were completed in 1120 Rh D negative women. For eight pregnancies no record of Rh D administration at birth was available. For recorded antenatal events that should have resulted in its administration anti-D was given in 195/280 (69.6%). Kleihauer testing was carried out in 9 of 98 instances of antepartum haemorrhage occurring after 20 weeks gestation. No cases of antenatal immunisation were identified.
The study identified a need to increase awareness of the necessity for anti-D administration after potentially immunising events during pregnancy, and for increasing compliance with administration of postnatal anti-D in one of the study regions. Re-evaluation is also required of the recommendation that Kleihauer testing should be done when antenatal anti-D is given following an obstetric event after 20 weeks.
