It has always been recognised that the practice of medicine requires an ethical base. This ethical base also provides a backbone for a legal framework. Until recently paternalism was the accepted norm in the physician-patient relationship. ⋯ Whether labouring women have capacity is discussed. There are times when patients are not able to act autonomously and the roles of advance directives (which can include birth plans) and substitute decision makers become important. The application of ethical practice to research in obstetric anaesthesia is considered.

Substance abuse, including that of cocaine, has crossed social, economic and geographic borders and remains one of the major problems facing society today. The prevalence of cocaine abuse in young adults (including women) has increased markedly over the past two decades. ⋯ The diverse clinical manifestations of cocaine abuse combined with physiologic changes of pregnancy, and pathophysiology of coexisting pregnancy-related disease might lead to life-threatening complications and significantly impact the practice of obstetric anesthesia. A complete understanding of the physiology of pregnancy, pathophysiology of pregnancy-specific disorders and anesthetic implications of cocaine abuse in pregnancy is essential to tailor a safe anesthetic plan for this high-risk group of patients.
