Long-term sedation with propofol in ICU: hemocoagulation problems

: The Authors have studied the effects of propofol on coagulation in 15 patients admitted to ICU. Propofol was used for long-term sedation (therapeutic range 3 mg/kg/h). Variables monitored included: platelets, PTT, PT, Fibrinogen, FDP, AT III. The effects on coagulation has been investigated in three groups of patients: group I) 5 patients that received propofol for 1-3 days; group II) 5 patients that received propofol for 4-10 days; group III) 5 patients that received propofol for 11-35 days. No difference were found about blood coagulation in this groups of patients before and after administration of propofol.
