High-dose propofol infusion for sedation of patients in the intensive care unit can result in rhabdomyolysis, acute renal failure, metabolic acidosis, hyperkalemia, ventricular arrhythmia, hyperthermia, and death. The death of a patient with such complications after lung biopsy is reported. Until a safer dosage range has been determined, propofol infusion at rates higher than 5 mg·kg−1·h−1 should be discouraged for long-term sedation (> 48 h).
