High-dose propofol infusion can cause serious complications like rhabdomyolysis and organ failure in intensive care unit patients. Doctors should avoid propofol doses exceeding 5 mg/kg/h for sedation longer than 48 hours.

Area of Science:

  • Critical Care Medicine
  • Pharmacology
  • Nephrology

Background:

  • Propofol is commonly used for sedation in intensive care units.
  • High-dose infusions may be associated with severe adverse events.

Observation:

  • A patient receiving high-dose propofol infusion developed rhabdomyolysis, acute renal failure, metabolic acidosis, hyperkalemia, ventricular arrhythmia, and hyperthermia.
  • The patient died following these complications after a lung biopsy.

Findings:

  • High-dose propofol infusion ( > 5 mg x kg(-1) x h(-1)) is linked to a spectrum of severe toxicities.
  • These complications can be fatal, as illustrated by the reported case.

Implications:

  • Propofol infusion rates exceeding 5 mg x kg(-1) x h(-1) should be avoided for long-term sedation (> 48 hours) until a safer dosage is established.
