What are the long term side effects of propofol?
Conclusion: The limited data available suggest that long-term infusion of propofol is a practical alternative to use of standard agents for sedation of intubated patients. Adverse effects such as cardiovascular depression, respiratory depression, and hypertriglyceridemia may limit the routine use of propofol.
Is propofol hard on the kidneys?
The renal clearance of propofol was 0.41 +/- 0.15 l/min (mean +/- SD), or 27 +/- 9.9% (mean +/- SD) of total body clearance. Human kidneys play an important role in the elimination of propofol.
Is propofol a sedative?
Propofol is an intravenous (IV) sedative-hypnotic agent that can be used for initiation and maintenance of Monitored Anesthesia Care (MAC) sedation, combined sedation and regional anesthesia, induction of general anesthesia, maintenance of general anesthesia, and intensive care unit (ICU) sedation of intubated,

Can propofol make you depressed?
This result indicated that propofol might cause the anxiety- and depressive-like behaviours in mice by affecting the inflammatory response in their brains. Propofol increased the IL-6 level in the brain tissues of mice compared to control mice.
Can propofol cause hair loss?
It’s thought that lengthy anesthetic periods could possibly lead to TE-related hair loss by causing reduced cell division. Slower cellular division may in turn inhibit hair follicle production. But this has not been proven in clinical studies. The type of anesthesia used may also contribute to hair loss.
Is propofol a depressant?
Propofol is a global central nervous system (CNS) depressant. It activates gamma-aminobutyric acid (GABA A) receptors directly, inhibits the N-methyl-d-aspartate (NMDA) receptor and modulates calcium influx through slow calcium-ion channels.
How do you get propofol out of your system?
When administered intravenously, propofol is rapidly cleared from the circulation. Its clearance takes place by redistribution possibly into the lungs and more importantly in the liver. Only 0.3% of the dose is excreted, unchanged, in the urine. The elimination half-life of propofol is approximately 0.5 h to 1.5 h.
Can propofol cause stroke?
Propofol-Induced Hypertriglyceridemia as a Cause of Stroke
Elevated serum triglycerides (TGs) are associated with increased long-term risk of ischemic stroke.
Is propofol a narcotic?

Is propofol a deep sedation?
The use of propofol increases the success of satisfactory deep sedation, but it can produce rapid and profound decreases in level of consciousness and cardiorespiratory function. Data are needed to assess the safety of this drug outside an anesthesiology setting.
What does propofol sedation feel like?
Most patients have little recall of “going under.” Those who do typically remember pleasant and relaxed feelings. Individuals who are sedated with propofol often report quite vivid dreams, which are typically pleasant in nature.
