Abstract

Abstract  in English, French

Background: Thrombocytopenia occurs in about 8-10% of pregnancies. Thrombocytopenia may be incidental in pregnancy and could point to medical or gestational conditions that may pose a morbidity and mortality risk to both mother and foetus.

Aim: To determine Obstetricians' view/opinion about thrombocytopenia in pregnancy.

Methods: A pre-tested structured questionnaire was distributed amongst consultant and resident obstetricians during their antenatal clinics in 3 tertiary hospitals over a period of one month. Analysis was descriptive and results were expressed as frequencies in words, tables and charts.

Results: A total of 91 responders were studied of which 24 were consultants (26.4%), 57 (62.6%) senior registrars and 10 (11%) were registrars. There were 20 (22.7%) responders who were unaware of incidental thrombocytopenia in pregnancy. Most obstetricians (n=83, 91.2%) requested for only packed cell volume (PCV) at antenatal booking, only 2 (2.9%) routinely requested for full blood count (FBC). At booking; only 10 (11.1%) obstetricians asked for a history of thrombocytopenia. Majority (n=87, 98.9%) never requested for platelet counts. If they encountered thrombocytopenia, up to 89 (97.8%) would investigate further with a repeat FBC (n=77, 86.5%), coagulation screen (n=54, 61.4%) or bone marrow aspiration (n=20, 24.7%). Most of the obstetricians (n=82, 96.5%) would transfuse patients with thrombocytopenia and 34 (43.6%) of them would do so when the count is <50 X 109/L.

Conclusion: Obstetricians have the capacity to investigate symptomatic thrombocytopenia in pregnancy but do not routinely screen for asymptomatic thrombocytopenia. Routine FBC if done at booking may identify missed cases of asymptomatic thrombo-cytopenia for adequate management.
