PSNet - Medication safety events related to diagnostic imaging (8 July 2022)

Summary

Some patients are unable to tolerate imaging procedures such as MRIs due to pain or anxiety. In these cases, a variety of medications are routinely used prior to imaging to allow the procedure to be carried out successfully. Varying levels of sedation before imaging can be appropriate given the need for patients to remain still during the imaging process, but the minimal amount of sedation should be used to mitigate unwanted side effects and reduce the risk of adverse events. This article examines two cases that highlight the risks of minimal-to-moderate sedation for imaging procedures, especially in high-risk patients, when multiple medication doses are required and when monitoring is limited or inadequate.
