There is no short, simple test for POCD. Typically, a series of neuropsychological tests are administered before and after surgery — a time-consuming process. Often, tests are given one week and again three months after surgery. But the tests used and time frames differ in various studies. Studies also define POCD differently, using varying criteria to assess the kind and extent of cognitive impairment that patients experience.
How common is it? The first international study of older adults with POCD those age 60 and older in suggested that Two years later, a study by researchers at Duke University Medical Center, published in the New England Journal of Medicine, found that 53 percent of adults who had heart bypass surgery showed significant evidence of cognitive decline when they were discharged from the hospital; 36 percent were affected at six weeks; 24 percent, at six months; and 42 percent, five years after their operations.
Another Duke study of older adults who had knee and hip replacements found that 59 percent had cognitive dysfunction immediately after surgery; 34 percent, at three months; and 42 percent, at two years. Other studies have produced different estimates.

The risk of experiencing POCD after surgery is enhanced in those who are older, have low levels of education or have cognitive concerns that predate surgery. Adults age 60 and older are twice as likely to develop POCD as are younger adults — a development that increases the risk of dying or having a poor quality of life after surgery.

And along with common potential side effects from anesthesia during surgery such as nausea, chills or muscle aches and itching, older patients are at risk for confusion or short-term memory loss. But rest assured, there are steps seniors can take to minimize these side effects. Grant, M. New approach to common hip surgery allows patients to come in at 9 a. Brain mapping is allowing surgeons to perform operations where the patient plays music or performs tasks to make sure the surgery is going well.
Anesthesia allergies are rare, but they can happen. We'll go over the symptoms of an allergic reaction to anesthesia as well as those of nonallergic…. MAC anesthesia — also called monitored anesthesia care or MAC — is a type of sedation during which a patient is aware and able to breathe on their own.
But what are the nitrous oxide side effects…. Local anesthesia is used to numb a small area before minor procedures, including dental work and some skin treatments. Learn more about the different…. Robert Burney, MD Retired.
I have long believed that cognitive mental defects following surgery and anesthesia were related to the decrease in cerebral blood flow CBF caused by anesthesia. CBF is determined by the blood pressure drop across the brain and by interstitial pCO2. It was--perhaps still is--routine practice to intubate and ventilate patients during general anesthesia.
The positive intra-thoracic pressure decreases perfusion pressure, and the end-tidal CO2 is not controlled. Regional anesthesia does not provide the expected antidote, because these patients are frequently not allowed to remain awake and breathe on their own.
This article deserves the attention of all doctors and health care providers involved in surgery and anesthesia. Primary care physicians and providers who refer patients for conditions that may lead to a recommendation for surgery particularly need a "pre-habilitation" focus.
The article highlights the growing body of evidence supporting improved outcomes for patients specifically managed in anticipation of the mental and physical insults sustained during even the most perfectly performed surgery. Many of the decrements in patient function can be considered iatrogenic because we are expanding our understanding of how to avoid or minimize them. Patients and their families need to be alerted to the value of the pre-habilitation model before being lost in an opaque referral process.
Patients and their families will need to be educated to the value of delayed surgery while interventions strengthen the patient's ability to cope with the known stressors of hospitalization, anesthesia, and surgery. Payors will require education in understanding the value of pre-habilitation interventions which will prevent complications related to surgeries requiring anesthesia.
This is another opportunity where collaboration between surgery and primary care will lead to better outcomes for our increasingly older and frailer populations. Access your subscriptions.
