We recommend close monitoring of laboratory and clinical markers for toxicity, such as arterial blood gas levels, lactic acid levels, and electrolyte levels as well as signs of cardiac dysfunction manifested by cardiac arrhythmias and hypotension, when prolonged propofol infusion is required for sedation in critically …

When should I stop propofol CK?

Once a patient presents with symptoms compatible with PRIS, propofol infusion should be discontinued promptly and an alternative sedative agent should be initiated. Cardiovascular support may require a combination of vasopressors and inotropes.

How often do you check triglycerides on propofol?

Propofol is considered a first-line sedative at our institution in mechanically ventilated patients who require continuous sedation. The maximum dose allowed in the ICU is 83 µg/kg/min, and it is recommended to monitor triglyceride levels every 48–72 hours for patients requiring prolonged infusions.

What are the contraindications of propofol?

Who should not take PROPOFOL?

  • low amount of magnesium in the blood.
  • low amount of potassium in the blood.
  • torsades de pointes, a type of abnormal heart rhythm.
  • prolonged QT interval on EKG.
  • abnormal EKG with QT changes from birth.
  • hardening of the arteries in the brain.
  • low blood pressure.
  • seizures.

Does propofol have active metabolites?

In humans, propofol produces inactive metabolites. It undergoes direct polymorphic O-glucuronidation in humans to propofol-glucuronide and hydroxylation to 2,6-diisopropyl-1,4-quinol.

How do you treat PRIS?

PRIS is difficult to treat once it occurs. The triggering factor is stopped and alternative sedative agents commenced. Cardiovascular support is provided as necessary and renal replacement therapy may be required to treat the ensuing lactic acidosis, clear propofol, and its metabolites from the patient rapidly.

Can propofol increase triglycerides?

Indeed, research has found a positive correlation between the duration of propofol infusion and increasing triglyceride (TG) levels, which may indicate onset of the deadly complication.

When does propofol infusion syndrome occur?

17 What is propofol infusion syndrome (PRIS)? The syndrome is not well understood but appears to be related to long-term (>48 hours), high-dose (>5 mg/kg/h) propofol infusion. The main features consist of cardiac failure (sudden onset of bradycardia), rhabdomyolysis, severe metabolic acidosis, and renal failure.

Is propofol safe for heart patients?

Sedation with propofol had to be discontinued in 11.7% of the procedures, predominantly due to hypotension. Trained nurses and cardiologists’ can safely apply this sedation regime, even in the setting of CA of patients with structural heart disease and impaired left ventricular function.

What is propofol infusion syndrome (PRIS)?

Propofol infusion syndrome (PRIS) is a rare and potentially fatal condition caused by shifts in intracellular energy production.

What are the mortality and morbidity associated with propofol administration?

Multivariate analysis showed that ECG changes, hypotension, hyperkalemia, traumatic brain injury, and mean propofol infusion rate >5 mg/kg/h are associated with an increased mortality.

What is the antidote for propofol in PRIs?

There is no antidote for propofol, but dextrose infusion may have some benefit due to the mitochondrial injury in PRIS. Emergent, supportive care should focus on mitigating ECG changes, hyperkalemia, hypotension, and fever.

What is propofol used for in critical care?

Critical care pharmacist and proud Rutgers University graduate. Enjoys rock climbing, cycling, travel, and lively discussions on the finer points of pharmacokinetics and critical care over a beer with friends. Propofol has become one of the most commonly used sedatives in critical care and anesthesia worldwide.
