PANDORA: Delirium Prevention After Cardiac Surgery Using IV Acetaminophen to Prevent Postoperative Delirium in Older Cardiac Surgical Patients

2019-09-23 04:51:41 | BioPortfolio


Our objective is to find an effective prophylactic intervention by evaluating IV acetaminophen's impact in reducing the frequency of postoperative delirium, one of the most common and detrimental complications of cardiac surgery in older adults.


This project will study the impact of scheduled administration of IV acetaminophen on the incidence, duration, and severity of postoperative delirium and other important hospital outcomes. Additionally, this trial will evaluate the effects of IV acetaminophen on longer-term postoperative cognitive dysfunction and functional status and develop a biorepository of perioperative samples as a future resource to probe the mechanisms of postoperative delirium.

The investigators propose three specific aims by conducting a randomized, triple-blind clinical trial that enrolls 900 patients 60 years of age or older undergoing cardiac surgery. Through this trial, the investigators will determine the effect of IV acetaminophen on;

1. the incidence, duration, and severity of postoperative delirium,

2. the use of opioids and other rescue analgesics in the first 48 postoperative hours, daily pain scores at rest and exertion, and length of stay in the Intensive Care Unit and overall hospital length of stay

3. longer-term (one, six, 12 months) cognitive, physical, and self-care functional recovery after surgery.

Medical and Biotech [MESH] Definitions

A form of DELIRIUM which occurs after GENERAL ANESTHESIA.

Cognitive disorders including delirium, dementia, and other cognitive disorders. These may be the result of substance use, trauma, or other causes.

An acute organic mental disorder induced by cessation or reduction in chronic alcohol consumption. Clinical characteristics include CONFUSION; DELUSIONS; vivid HALLUCINATIONS; TREMOR; agitation; insomnia; and signs of autonomic hyperactivity (e.g., elevated blood pressure and heart rate, dilated pupils, and diaphoresis). This condition may occasionally be fatal. It was formerly called delirium tremens. (From Adams et al., Principles of Neurology, 6th ed, p1175)

Misunderstanding among individuals, frequently research subjects, of scientific methods such as randomization and placebo controls.

Analgesic antipyretic derivative of acetanilide. It has weak anti-inflammatory properties and is used as a common analgesic, but may cause liver, blood cell, and kidney damage.
