We retrospectively audited children with sickle cell disease (SCD) admitted to paediatric intensive care (PICU) at King's College Hospital between January 2000 and December 2008. Forty-six children with SCD were admitted, on 49 separate occasions. Ages ranged from 4 months to 15 years (median 7.6 years). Three children died in PICU, however two presented to hospital in cardiorespiratory arrest; overall mortality was 6%. The most common reason for admission was acute chest syndrome (43%). 88% of admissions required blood transfusion, of which 74% had exchange blood transfusions. The mortality among children with SCD admitted to PICU is low.
