Cognitive impairment, anesthesia, and critical illness: learning from the past to gain perspective on the future.
This study examined the link between cognitive impairment, ICU admission and anesthesia. The author’s hypothesis was that patients with cognitive impairment would be more likely to undergo surgical procedures. However, analysis using data from the Mayo Clinical Study on Aging on 1,977 cognitive normal patients, 387 patients with mild cognitive impairment (MCI), and 72 patients with established dementia found that patients with MCI were more likely to undergo anesthesia and those with dementia were less likely to undergo procedural anesthesia. The author hypothesizes this may be linked to impaired decision-making of the patient and the risk-benefit analysis of performing surgery on patients with established dementia. However, ICU admissions were increased in patients with MCI and dementia.
