|Ischemic Coronary Artery Disease Coronary Artery Bypass Surgery||Drug: fospropofol Drug: propofol||Phase 2|
This Phase 2, open-label, single-center, randomized clinical trial was designed to examine the efficacy and tolerability of AQUAVAN® Injection (hereafter, referred to as AQUAVAN) when used to preoperatively sedate, induce, and maintain general anesthesia and to postoperatively sedate patients undergoing elective coronary artery surgery. Eligible patients were randomized to either AQUAVAN or DISOPRIVAN® Injectable Emulsion (hereafter, referred to as DISOPRIVAN) following screening and prior to their arrival in the surgical suite.
On the day of surgery, after the administration a 0.5 mg/kg bolus dose of lignocaine, preoperative sedation began using the target-controlled infusion (TCI) system to target desired sedation plasma concentrations of either AQUAVAN or DISOPRIVAN, depending on the randomization schedule.
The Bispectral (BIS) Index was used to guide study drug administration; target BIS ranges were 60 to 80 for sedation and 40 to 60 for the maintenance of anesthesia. Adequate sedative/hypnotic effect during surgical anesthesia was characterized by the portion of time within the target BIS Index range versus total surgical time. Following this, during postsurgical sedation, inadequate sedative/hypnotic effect was characterized by the number, duration, and magnitude of BIS scores outside of the target range versus total postsurgical sedation time. During postsurgical sedation, the Modified Ramsey Scale was used as an additional clinical tool to evaluate the state of sedation, with an attempt to maintain the score between 3 and 5.
The overall quality of induction, maintenance and ease of control of anesthesia, and quality of sedation before and during cardiopulmonary bypass (CPB), were each graded by the anesthesiologist.
Continuous monitoring of blood pressure and heart rate were used to assess the hemodynamic effect of study drug. Hypertension and hypotension were defined as excursions of >/= 20% from the baseline value.

Using a Target Controlled Infusion (TCI) system, the target plasma concentrations of propofol to be administered from AQUAVAN were 0.7 μg/mL (sedation) and 2.5 μg/mL (maintain anesthesia).
|Active Comparator: propofol||
Using a Target Controlled Infusion (TCI) system, the target plasma concentrations of propofol to be administered from Disoprivan were 1.0 μg/mL (sedation) and 3.0 μg/mL (maintain anesthesia).
