Analyzing the Relationship Between Speed Propofol is Given and Low Blood Pressure

Analyzing the Relationship Between Rate of Induction and Perioperative Hypotension Using Propofol

The objective of this study is to evaluate the hemodynamic changes related to Propofol administration rate. We hypothesize that slow administration of IV propofol will have less hemodynamic disturbances and will require less amount of vasoactive medication for BP correction when compared to standard FDA approved administration rate.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Patients Administered Propofol at a Slower Rate of Infusion Will Have Lower Incidence of Post Induction Hypotension Than Patients Administered Propofol at FDA Approved Rate.	We will collect the patient's blood pressure intra-operatively every 5 minutes starting on induction up to one hour after induction and compare.	induction to 1 hour post induction

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Patients Administered Propofol at a Slower Rate Will Have Less Complications During the Early Post-op Period Than Patients Administered Propofol at FDA Approved Rate.	We will collect the patient's blood pressure post-operatively and length of hospital stay and compare.	immediate post-op to 30 days post operatively
