The purpose

Recent data suggests that anesthetics can have prolonged effects on gene expression, protein synthesis and processing as well as cellular function in ways that the investigators are only beginning to understand, especially in the very young and the elderly. Within moments to days of emerging from anesthesia - cardiac or non-cardiac - some patients experience mild to very severe disorientation and changes in memory and thinking ability without apparent cause. For the vast majority of patients, this Post-Operative Cognitive Dysfunction (POCD), generally subsides, but for some with "diminished cognitive reserve" - especially the elderly, those with less education or prior CNS events such as stroke or early dementia - changes in memory and executive function may persist. If prolonged for more than three months, POCD has been linked to an increased risk of death. In 1-2% of elderly patients, the problem may ultimately continue for more than a year, leading to a loss of ability to care for themselves and early demise. Though this may seem like a small percentage, seniors will comprise up to 40% of the 50-75 million surgical procedures performed annually over the next 20-30 years. This amounts to 70,000 - 200,000 elder affected, and for them and their families, the cost of POCD in longer-term care, lost wages, and extended suffering will remain very high.
