Postpartum Magnesium Sulfate Overdose: A Multidisciplinary and Interprofessional Simulation Scenario

This case is one of an eight-case multidisciplinary curriculum designed and implemented at the University of Ottawa by simulation educators with specialty training in obstetrics and gynecology (OB/GYN) and anesthesiology. Consultation with a nurse educator maintained the quality and relevance of objectives for nursing participants. The curriculum was prepared to train OB/GYN and anesthesiology residents and labor and delivery nurses to hone crisis resource management skills and to recognize and manage rare/critical medical events in an obstetrical setting. Obstetricians, anesthesiologists, and nurses often work together in acute, high-stakes situations and this curriculum provides a safe environment to practice team-based management of such emergencies. Over an eight-year period, this curriculum has been executed in scenario couplets in a four-year cycle to allow OB/GYN and anesthesiology residents exposure to all scenarios during a five-year residency, beginning in their second year. Prospective evaluative data has been positive. For example, over 90% of participants rated these simulations to be 5 out of 5 for "Was an effective use of my educational time" and "Will influence/enhance my future practice." In this scenario, participants must evaluate and treat a postpartum preeclamptic woman who is being treated with magnesium sulfate for the purpose of seizure prophylaxis. The patient experiences magnesium sulfate toxicity and subsequent respiratory arrest. Any mannequin that can display vital signs can be used for this scenario. This simulation case includes a case template, critical actions checklist, debriefing guide, summary of key medical content, and an evaluation form for learners to provide feedback.
