Simulation-based training in obstetric anesthesia: an update

•Simulation-based training has an important role in maternity care.•The use of checklists can reduce human error and increase task completion.•Low- and high-fidelity approaches can achieve learning objectives.•Training must be tailored to suit the particular practice context. In this update we explore the current applications of simulation in obstetric anesthesia, describe what is known regarding its impacts on care and consider the different settings in which simulation programs are required. We will introduce practical strategies, such as cognitive aids and communication tools, that can be applied in the obstetric setting and share ways in which a program might apply these tools. Finally, we provide a list of common obstetric emergencies essential for a program’s curriculum and common teamwork pitfalls to address within a comprehensive obstetric anesthesia simulation program.
