Labour Epidural with Gestational Thrombocytopenia

You have been asked to put in an epidural in a G1 P0 woman who has presented in spontaneous labour at 38 weeks' gestation. She has a normal body habitus. She has no significant past medical history. Her antenatal history is unremarkable other than stable gestational thrombocytopaenia. An FBE was performed at 36 weeks gestation. Hb 129 g/L (115-165) WCC 11 x 10^9/L (4-11) Plt 88 x 10^9/L (150-400) When you enter the room, she is in obvious pain and states "Just put the epidural in!"
