Labour Epidural with Language Barrier

You are the anaesthetist on-call in a large regional hospital. You have been asked to provide epidural analgesia to a 32-year-old parturient (gravida 1, para 0, 41+1 weeks gestation) after commencement of induction of labour for prolonged pregnancy. The midwife informs you that the patient moved from Mongolia two years ago and is not fluent in English, although her husband is fluent in English. She has had an unremarkable antenatal course. Her past medical history includes mild asthma (no regular treatment required). When you attend the patient, she is noted to be in established labour with some distress due to contraction pain. She is 148 cm tall and weighs 55 kg.
