Obstetric neuraxial anaesthesia in the context of maternal immune thrombocytopenia: secondary analysis of a retrospective cohort study

Editor—Immune thrombocytopenia (ITP) is an autoimmune condition affecting 1–10 in 10 000 pregnancies.¹ The bleeding risk associated with significant thrombocytopenia poses a challenge peripartum, particularly for placement of neuraxial anaesthesia, where evidence to guide practice remains scant.² Our aim is to describe our experience with neuraxial anaesthesia in the setting of ITP in pregnancy at two tertiary-level academic institutions. The report is a secondary analysis of a retrospective study of pregnant women with ITP at two tertiary-level Canadian academic institutions: Mount Sinai Hospital (MSH), Toronto and McMaster University Medical Centre, Hamilton (MUMC) from January 2000 to August 2014.³ Research ethics board approval was granted at both hospital sites.
