title: Serum lipid and glucose concentrations with a propofol infusion for cardiac surgery.
abstract: OBJECTIVE
  To document changes in serum lipids and glucose with a propofol infusion technique for cardiac surgery.
  
  
  METHODS
  Prospective cohort.
  
  
  METHODS
  University teaching hospital.
  
  
  METHODS
  22 elective cardiac surgical patients.
  
  
  METHODS
  Frequent venous blood sampling.
  
  
  RESULTS
  Serum lipids and glucose were measured at 10 time periods perioperatively, from preinduction until 4 hours post-cardiopulmonary bypass. Plasma propofol concentrations were also measured in 10 of these patients. There was a significant increase in glucose (P < 0.0005) and decreases in cholesterol (P < 0.0005), high-density lipoprotein (P = 0.004), and low-density lipoprotein (P < 0.0005); there was no significant change in triglycerides (P = 0.39). The propofol infusion resulted in acceptable plasma levels throughout the procedure and allowed early extubation in the intensive care unit, after a mean (SD) of 7.14 (5.9) hours. There was a strong correlation between triglyceride and propofol levels at most time periods (r = 0.38 to 0.98).
  
  
  CONCLUSIONS
  This study demonstrates that a propofol infusion technique does not result in elevation of serum lipids and supports its increased popularity in maintenance of anesthesia for cardiac surgery.
