Managing cardiovascular incidents in the intra-operative magnetic resonance imaging (iMRI) environment: Lessons from three case studies

Abstract

In recent years, the use of magnetic resonance imaging (MRI) has extended into the operating theatre, especially in the field of neurosurgery. By providing real-time images during surgery, intra-operative MRI (iMRI) facilitates safer and more complete brain tumour resection. However, the iMRI environment poses additional challenges to the anaesthetist when managing intra-operative cardiovascular events. Through three case examples, this article will discuss the issues of cardiovascular resuscitation, cardiac pacing and cardiovascular monitoring in the iMRI environment.
