Summary

Propofol infusion syndrome can occur even with short anesthesia, potentially causing metabolic issues. Immediate cessation of propofol and supportive care are crucial for managing this critical condition.

Area of Science:

  • Anesthesiology and Critical Care Medicine
  • Pharmacology
  • Biochemistry

Context:

  • Propofol infusion syndrome (PRIS) is a rare but serious complication.
  • It has been observed in both long-term sedation and shorter anesthesia durations (≥5 hours).
  • Underlying mechanisms involve impaired fatty acid oxidation and mitochondrial dysfunction.

Purpose:

  • To review the pathophysiology, clinical presentation, and management of propofol infusion syndrome.
  • To highlight the potential risks associated with propofol use in critically ill patients.
  • To emphasize the importance of early recognition and intervention.

Summary:

  • Propofol infusion syndrome is linked to mitochondrial dysfunction, leading to lactic acidosis and muscle damage.
  • High catecholamine and cortisol levels in severe illnesses may act as triggers.
  • Immediate discontinuation of propofol, metabolic correction, and renal replacement therapy are key management strategies.

Impact:

  • Reconsideration of long-term propofol sedation in critically ill patients is advised.
  • Early suspicion of PRIS is vital for prompt diagnosis and treatment.
  • Understanding PRIS pathophysiology aids in developing safer anesthetic and sedation protocols.
