You are the haematology registrar on call (non-resident in the evening). It’s 6:15 pm and as you’re walking into your home, you get called by the medical SHO on the Acute Medical Unit for advice on pre-procedure platelet transfusion. They would like to perform a diagnostic lumbar puncture to exclude encephalitis in a 31-year-old woman who presents with fevers, confusion and a headache. Her platelet count has come back as 13 x 10^9/L.
Would you be happy to advise on platelet transfusion with the information provided here?
If not, what further information would be helpful and what steps would you take to help guide your decision making in this situation?
