Trends in Pediatric MRI sedation/anesthesia at a tertiary medical center over time
© 2021 John Wiley & Sons Ltd..
BACKGROUND: Each year, hundreds of thousands of children require sedation/anesthesia to facilitate MRI scans. Anesthetic techniques for accomplishing sedation/anesthesia vary widely between institutions and providers, with unclear implications for patient safety.
AIMS: We sought to establish trends in anesthetic practice for pediatric MRI sedation/anesthesia across a 7-year period and determine rates of adverse events, considering technique used, age, and ASA physical classification status (ASA-PS).
METHODS: Using established data resources, we analyzed 24 052 anesthetics performed by anesthesiologists for MRI scans between 5/1/2013 and 12/31/2019 on patients less than 18 years old, focusing on medications used, trends of use, and associated adverse events. Adverse events (hypoxia, hypotension, bradycardia) were defined by deviation from age norms and accessed via the electronic anesthetic record database. The Cochran-Armitage test was used to assess trends over time in categorical data, and one-way ANOVA was used to analyze continuous data. Multivariable logistic regression analysis was implemented to determine the independent associations between anesthetic technique and adverse events while adjusting for age, ASA-PS, and weight.
RESULTS: The most significant trends noted were a decrease in "propofol-only" anesthetic techniques and an increase in propofol and dexmedetomidine combination techniques. Mild desaturation (80-89% SpO2 ) occurred in 4.22% of cases with more significant hypoxia much rarer (0.44% of cases having desaturation <70% SpO2 ). Bradycardia occurred in 2.39% of cases and hypotension in 1.75% of cases. Major adverse events were rare.
CONCLUSIONS: We provide the largest report of the nature of MRI sedation/anesthesia as practiced by anesthesiologists in a large children's hospital. We demonstrate that, even in a large system, anesthetic techniques are pliable and shift significantly over time. Our data also support a high level of safety within our system, despite a case mix likely higher in risk than those in most of the previously published studies.
