Etiology
- myocardial infarction[2]
- electrolyte imbalance
- untreated pain
- urinary tract infection[2]
- postoperative pneumonia
- risk factors[2]
- preoperative cognitive dysfunction is the major risk factor[1][2]
- preoperative plasma tau-p217 & plasma tau-p181 are associated with postoperative delirium, with plasma tau-p217 the stronger indicator[21]
- history of stroke or transient ischemic attack (TIA)
- depression (Geriatric Depression Scale score > 4)
- low serum albumin
- age >= 70 years[11]
- alcoholism
- tobacco use[14]
- functional impairment
- dehydration
- abnormal serum glucose
- dementia & intensive care unit admission[9]
- visual impairment
- severe illness
- intrathoracic surgery
- aortic aneurysm surgery[2]
- duration of surgery[14]
- lymph node involvement in head & neck cancer surgery[14]
- intraoperative hypotension may play a role[6]
- perioperative gabapentin increases risk of delirium (RR=1.3)& new antipsychotic use (RR=1.2) in elderly patients after major surgery[22]
- postoperative opiates for pain control do not seem to play a precipitating role[9]
- hypertension & anemia* do not seem to play a role[2]
- consider drug withdrawal syndrome
* anemia would seem to be a risk factor in other sources
* BUN/creatinine ratio does not predict postoperative delirium in elderly[2]
Complications
- longer hospitalization, more days with mechanical ventilation, functional decline
- prolonged cognitive impairment after postoperative delirium[1]
- postoperative improvements in patients with preoperative cognitive impairment attenuated by postoperative delirium[15]
- progressive cognitive decline, dementia, & death[18]
- accelerated cognitive decline that continues for at least 72 months[24]
Management
- see delirium
- preoperative cognitive assessment is the best predictor of risk for postoperative delirium
- preoperative cognitive exercises may diminish risk of postoperative delirium[17][18]
- medical consultation by orthopedic surgeons with internists/geriatricians reduces 1 year mortality (RR=0.69)[3]
- preoperative geriatric assessment reduces postoperative delirium[2]
- keep hematocrit >= 30%
- adequate hydration & pain control[23]
- prevention of postoperative delirium in the elderly
- family involvement is effective in preventing postoperative delirium in older adults[16]
- personalized stimulation, company, & relaxation reduces postoperative delirium after non-cardiac surgery[19]; no benefit after cardiac surgery
- rivastigmine is not useful[4]
- statins are not useful[13]
- avoid gabapentin[22]
- use of atypical antipsychotic no less likely than haloperidol to result in death or non-fatal adverse in-hospital events[25]
- perioperative haloperidol
- 0.5 mg PO TID from up to 72 hours preoperatively until postoperative day 3
- does not alter the incidence of postoperative delirium (15.1%) vs placebo (16.5%)[5][7]
- does reduce delirium severity ratings, delirium duration (mean: 11.8 to 5.4 days), & length of hospital stay (mean: 22.6 to 17.1 days)[5]
- electroencephalogram (EEG)-guided anesthetic depth controversial[18]
- early postoperative ambulation has not been shown to reduce postoperative delirium[2]
