Objective:This article was to investigate the
hemodynamic effects of the mixture from propofol and fentanyl on propofol critically ill patients
for prolonged sedation during mechanical ventilation.Methods: 24 patients were admitted to ICU
with mechanical ventilation and sedation started as required. Eleven patients were assigned to
placebo group receiving midazolam 5 10 mg or fentanyl 0.1 0.2 mg i.v;and thirteen to propofol
group recieving infusion of a mixture from propofol 400 mg and fentanyl 0.5 mg at 2 ml·kg -1
·h -1 for a maximum of 4 days. Results:CI and SI increased significantly in propofol group
on the second day of adminision to ICU ( P 0.01). MAP and PAP decreased lightly,but the
differences were not significant. HR,CVP and PCWP were found to have no changes in either
group. Propofol significantly decreased SVRI and PVRI on the second day of adminision ( P 0.
05).Conclusion:Infusion of mixed liquid for propofol and fentanyl could provide satisfactory
sedation for ICU patients with little hemodynamic changes.
