Comparison the Hemodynamics Effects Between Dexmedetomidine and Propofol in Major Abdominal Surgical Patients
When the patients can be roused, they will first receive analgesia with bolus of fentanyl
0.03mg, followed by a continuous infusion at a ﬁxed dose of 0.3μg/kg/h during study period.
Then patients will be randomly divided into two groups (Dexmedetomidine and Propofol). All
of them will receive hemodynamic monitoring through "Vigileo"(Edwards Lifesciences) and
cardiogram monitor. The study will continue for 6-24 hours.
Observational Model: Case Control, Time Perspective: Prospective
the study will start when the patient can be roused after major abdominal surgery and will continue for 6 to 24hours
