Post-operative cognitive dysfunction (POCD) is a state in which a patient’s memory and learning decline after surgery. POCD is common: 1 in 3 patients will have POCD at discharge. 1 in 10 patients will have POCD that lasts up to three months after surgery.
What is postoperative delirium?
Post-operative delirium is delirium that happens after an older adult has an operation (surgery) and is the most common post-operative complication in older adults. Delirium can have many causes – for example, drugs, infection, electrolyte imbalance, and not being able to move around (immobilization).
How long does post-operative cognitive dysfunction last?
In contrast to postoperative delirium, which typically lasts a few hours to a few days after surgery, POCD is generally understood to refer to cognitive dysfunction that lasts from one week up to three months after surgery.
How is Pocd diagnosed?
POCD is usually transient. It is diagnosed by comparing pre- and postoperative findings on psychometric tests. Its pathogenesis is multifactorial, with the immune response to surgery probably acting as a trigger.
Can propofol cause confusion?
Patients received either propofol or one of several anesthetic gases. The morning after surgery, 16 percent of patients who had received light anesthesia displayed confusion, compared with 24 percent of the routine care group.
What are the most common postoperative complications?
The most common postoperative complications include fever, small lung blockages, infection, pulmonary embolism (PE) and deep vein thrombosis (DVT).
Is postoperative delirium permanent?
Delirium after surgery is often temporary, but it can affect your loved one’s recovery, leading to a longer hospital stay or discharge to a rehabilitation facility instead of directly to home. Most people with delirium after surgery recover within a month to six months.
When does postoperative delirium occur?
Post-operative delirium (POD) is a form of delirium that manifests in patients who have undergone surgical procedures and anesthesia, usually peaking between one and three days after their operation.
How is post op delirium diagnosed?

- Agitation.
- Difficulty focusing.
- Fatigue and sluggishness.
- Hallucinating.
- Slurred speech.
- Restlessness.
- Rapid mood swings.
- Uncooperative or aggressive behavior.
How do you manage post op delirium?
Specific interventions which have been shown to reduce delirium include: (1) an orientation protocol to provide the patient with repeated orientation to their surroundings and care team members, (2) a sleep protocol to provide uninterrupted night time sleep, (3) an early-mobilization protocol to allow for daily …
How can we differentiate between delirium related to anesthesia and dementia?
Dementia develops over time, with a slow progression of cognitive decline. Delirium occurs abruptly, and symptoms can fluctuate during the day. The hallmark separating delirium from underlying dementia is inattention. The individual simply cannot focus on one idea or task.
Are postoperative delirium and postoperative cognitive dysfunction the same thing?
Postoperative delirium is typically assessed within days after surgery and shows a peak incidence on postoperative days 1 to 3, but postoperative cognitive dysfunction is typically assessed at 1 to 3 months after surgery. Fourth, there are few if any human studies demonstrating that these disorders share the same pathophysiologic mechanisms.
What is postoperative cognitive dysfunction in cardiac surgery?
Postoperative cognitive dysfunction refers to a persistent cognitive dysfunction that occurs subsequent to surgery and anesthesia that is beyond postoperative delirium, a transient state of cognitive change. Until recently, the majority of research on postoperative cognitive dysfunction has focused on cardiac surgery.
What is the rate of incidence for postoperative delirium?
It is estimated that postoperative delirium occurs in at least 20% of the 12.5 million individuals aged 65 years or older who are hospitalized each year and increases the cost of hospitalization by $2500 for each patient who develops this complication [5].
What are the signs and symptoms of postoperative delirium in cirrhosis?
The presentation of postoperative delirium is variable and patients may exhibit hyperactive, hypoactive, or mixed hyper-hypoactive cognitive and motor states. Hyperactive patients show increased psychomotor activity, such as rapid speech, irritability, and restlessness and are often disruptive, time-consuming,…
