Introduction:
Getting older can lead to more wisdom, but it can also mean a higher chance of health issues. Some health problems might need surgery for improvement. In fact, one in ten individuals needing surgery are 65 years or older. At one age, the likelihood of surgery increases, but it can also raise the chances of complications. Typical age-related health problems like high blood pressure, blocked arteries, and heart and lung conditions might make side effects or surgery complications more probable. Moreover, simply being older can result in uncomfortable side effects.
What Are the Side Effects of Anesthesia in Older Adults?
Older patients may face particular problems because their aging brains can be more sensitive to anesthesia, a drug that prevents pain during surgery by causing drowsiness or unconsciousness. There are two anesthesia-related surgery concerns that happen more often in older individuals:
-
Post-operative Delirium: This is a temporary condition where the patient becomes confused, disoriented, and struggles with memory and focus. It might not appear until a few days after surgery, can come and go, and usually disappears after about a week.
-
Post-operative Cognitive Dysfunction (POCD): This is a more serious issue that can lead to long-term memory loss and make it tough to learn, concentrate, and think. Since some of these problems are already common in older people, the only way to know if a patient actually has POCD is to do a mental test before surgery. Certain conditions, like heart disease (especially congestive heart failure), lung disease, Alzheimer’s disease, Parkinson’s disease, and a history of stroke, increase the risk of POCD. Researchers in anesthesia care are continually investigating these conditions and working to find ways to prevent or reduce their effects.
What Can Be Done to Lower Anesthesia Risks in Older Patients?
To decrease the chances of anesthesia problems in older patients, it is crucial to have a conversation with the doctor or surgeon to ensure an anesthesiologist is in charge of the anesthesia care.
One could also inquire if there is an anesthesiologist who specializes in older patients or has more experience with them who can handle the patient with care. There are actions that can be taken before, during, and after surgery to help minimize the risk of age-related anesthesia issues.
During the meeting with an anesthesiologist before surgery, ensure discussing any health problems one might have, all medications taken, including vitamins or herbs, and express any concerns or fears about the surgery. Describe any past surgeries and any issues experienced with anesthesia previously. Also, talk about any memory or thinking problems experienced after anesthesia.
Having a trusted person, such as a family member or friend, present during these discussions is wise. They may remember things forgotten or considered unimportant and might offer valuable insights about health or behavior. Another set of ears can also help remember the anesthesiologist's advice, including instructions for preparing for surgery.
The anesthesiologist will use this information to create the best anesthesia plan, reduce complications, and closely monitor during the surgery.
Other steps to prevent issues and reduce confusion include:
-
Requesting a pre-surgery cognitive test from the doctor to assess thinking abilities. This will serve as a baseline for comparison after surgery.
-
Ensuring the person who spends the most time with the patient is present during recovery, observing physical and mental conditions, and reporting any concerns to the doctor.
-
Consult with the doctor before taking drugs that affect the nervous system, such as anxiety medications, muscle relaxants, or sleep aids, after surgery.
-
Requesting the availability of hearing aids or glasses after the procedure, if used.
-
If possible, select a recovery room with a window to distinguish between day and night.
-
When staying overnight in the hospital, bring familiar items from home, like a family photo, clock, or calendar, to aid in adjusting.
Is It Advisable to Avoid General Anesthesia for Older Adults?
For caregivers, deciding on surgery for a loved one can be challenging. While the connection between dementia and anesthesia remains unclear, it is evident that undergoing surgery can lead to lasting physical and cognitive issues in some elderly individuals. Although many seniors recover well from procedures like hip replacements and open heart surgery, others may never regain their cognitive abilities to the level they had before surgery.
It is crucial to engage in open communication with all members of the senior healthcare team when assessing the risks and benefits of medical treatments, particularly surgical ones. Factors to consider in making this decision include the patient's age, physical and mental health, and how the treatment will impact their overall quality of life. For instance, if a senior remains quite active and is in reasonable health but suffers from severe arthritis, joint replacement surgery could greatly improve their mobility and functional abilities.
Is Preoperative Evaluation Crucial?
A thorough preoperative assessment is essential to prevent complications during and after surgery. Scientists are still exploring the causes and risks of postoperative cognitive dysfunction (POCD). To ensure a safe procedure, it is crucial for patients to undergo a comprehensive evaluation with their primary care physician. Surgeons and anesthesiologists must be informed about the patient's essential health details, including their medication regimen. Certain medications, like beta blockers, opioids, and blood thinners, can interact negatively with anesthesia drugs. Pre-existing conditions, even seemingly minor ones like urinary tract infections, can impact the surgical experience. For individuals with heart or lung issues, specialized tests may be needed for medical clearance before surgery.
Additionally, the senior's ability to participate in post-operative rehabilitation is a significant consideration. Older adults experiencing new or worsening cognitive decline may struggle to comprehend and follow recommended physical and occupational therapy in senior rehabilitation programs.
Depending on the type of surgery needed, opting for milder sedation, which often entails fewer side effects, may be a preferable choice. Regional anesthesia, when used alongside sedation, can be a safe and effective alternative to general anesthesia for many surgeries. Procedures involving epidurals, nerve blocks, and spinal anesthesia frequently result in reduced recovery time, pain, side effects, and costs. However, it is essential to note that these approaches are not typically used in open heart, abdominal, and brain surgeries.
Conclusion
In summary, addressing the effects of anesthesia in older adults involves careful preoperative evaluation and open communication with healthcare professionals. The risks and benefits of surgery, especially in the elderly, must be thoroughly considered. Anesthesia can present unique challenges for older patients, with potential complications like post-operative delirium and cognitive dysfunction. To minimize these risks, it is essential to discuss health history, medications, and concerns with an anesthesiologist. Having a trusted companion present during these discussions can be invaluable. Additionally, milder sedation options, like regional anesthesia, may be suitable alternatives for certain surgeries.
