Safety of intraoperative monitoring in pregnant patient: literature review and brainstem case study.

Abstract Objective Intraoperative neuromonitoring (IONM) is used to assess the integrity of neural pathways and aids in optimizing surgical results and avoiding neurologic injury. However, there are few reports of its use and safety in pregnant patients. We will perform a literature review on IONM in pregnancy. In addition to this review, we will report our experience with IONM in a 20-week pregnant patient that presented with a brainstem tumour, which has not been reported before in the literature.
