Anesthesia and Cognition Impairment Report

  • While surgery is very common, patients sometimes fear that they will experience some type of future impairment because of an operation. Many elderly patients may even opt out of having a procedure that will give them a better quality of life because they are worried having surgery that requires anesthesia may lead to cognition impairment. A new study, however, hopes to prove just the opposite. Cognitive Test Results of Twins The University of Southern Denmark has recently released results from their study that examined a total of 8503 twins. Of these twins, 4299 were under the age of 70 and the remaining 4204 were over the age of 70. Cognitive tests of twins that had undergone surgery requiring anesthesia within the past 18-24 years were compared to test results of twins who had not had any type of surgical procedure. Results showed that twins who had undergone surgery in recent years had slightly lower scores on cognitive tests, however, researchers stated that the differences were not statistically significant. Unni Dokkedal, from The University of Southern Denmark, said, “Our use of twins in the study provides a powerful approach to detect subtle effects of surgery and anesthesia on cognitive functioning by minimizing the risk that the true effects of surgery and anesthesia are mixed up with other environmental and genetic factors. We found no significant cognitive effects related to surgery and anesthesia in these patients, suggesting that other factors, such as preoperative cognitive levels and underlying diseases, are more important to cognitive functioning in aging patients following surgery.” All Part of the Postoperative Puzzle Postoperative cognitive dysfunction is normal for a short time after a surgery, but this study shows receiving anesthesia alone does not cause cognitive impairment. This leads researchers to focus on other factors that may play a role in postoperative cognitive impairment. A researcher from the study said, “This research has the potential to become a key piece of this very complex research puzzle.” Researchers believe this information will especially help older patients when faced with the decision of having an operation with anesthesia. Although there may be other factors that cause a person to have some cognitive issues after an operation, patients can have some peace of mind knowing it will not be caused by anesthesia.

  • Although the development of anesthesia took place in the 1840’s, surgery was still not regularly performed due to fear of infection and other complications. That was until the Civil War started in 1861, which caused the number of necessary operations to drastically increase. According to an article in the newsletter of the American Society of Anesthesiologists by Maurice S. Albin, M.D., “The sheer magnitude of battlefield injuries during the conflict played a major role in establishing the regular use of anesthesia.” The need for surgery was greater than ever before, which gave physicians no choice but to use anesthesia to operate. Methods Prior to Anesthesia Prior to the the war, patients may have been given something to bite on, alcohol, opioid drugs, or put in physical restraints to keep them under control during surgery. According to Albin, “It was thought to be unmanly for a male to undergo surgery with an anesthetic, which was usually reserved for women and children. There was even a belief that the use of ‘cold steel’ had a beneficial effect, and it would not cause the depression thought to occur with the use of anesthesia.” “Real Men” Don’t Need Anesthesia The idea of anesthesia being “unmanly”, quickly shifted as the war progressed and the number of injuries rapidly increased. It became a necessity in battlefield hospitals, and is believed that there were around 120,000 uses of anesthetic agents by surgeons on both sides during the battle. Anesthesia on the Fly At the time of the Civil War, many surgeons and physicians had little no experience with using an anesthetic during operations. They were forced to rely on manuals which gave them instructions on how to properly use anesthetics such as ether and chloroform. Although many doctors lacked experience with these agents, mortality rates associated with the use of an anesthetic were surprisingly low. Albin stated, “After the termination of this horrendous conflict, these doctors would return to their practices, hospitals and medical schools, all the richer for being exposed to this unique American contribution to the life-easing quality of mercy — the discovery of anesthesia.” Physicians benefited from learning firsthand the techniques and uses of anesthetics, and many lives of wounded soldiers were saved as a result. Today, millions of people undergo anesthesia each year in the United States alone, and it has become extremely common. Although anesthesia has developed and changed over the years, its regular use was established during the time of the Civil War.

  • Before the development of Ambulatory Surgery Centers, or ASCs, it was not uncommon for patients to wait several weeks or months to get an appointment for surgery, or to spend days or weeks in the hospital recovering. With hopes to change this by providing affordable and accessible outpatient surgery alternatives, two doctors, named Wallace Reed and John Ford, came up with the idea for freestanding ambulatory surgery centers. In 1970, this idea became a reality when they opened their first Ambulatory Surgery Center called, Surgicenter, in Phoenix, Arizona.

  • The effects of the use of anesthesia on infants and young children have been a concern for doctors and parents for many years. Each year, millions of patients are exposed to anesthesia during surgery, and about a half a million of those patients are children under the age of three. In the past, studies have been done on young monkeys and other animals that showed anesthetics may kill brain cells, affect memory, and cause behavioral problems. However, since these were animals and not children, these studies offered no definitive results.

  • The last of this four part series striking down the myths behind the use of an anesthesia management solutions focuses on time. Many facilities are of the mindset that by having their own, in-house anesthesia team provides them with the most flexible option as it relates to availability and time. However, regional anesthesia management solutions actually have the ability to offer improved flexibility as it relates to anesthesia services.

  • In today’s world, every company is being asked to take on more responsibilities with the same or, unfortunately, sometimes even less resources.  Finding cost efficiencies does not always mean going without something; it sometimes means absorbing the workload in another area.  The world of healthcare, and anesthesia, is not immune to this practice.
