Measure
Choline
Participants ingested ten tablets (GNC Triple Lecithin 1200 choline tablets) containing 12 g of high choline lecithin and 4.2 g phosphatidyl choline the night before surgery. On the day of surgery, a second dose of study drug (equivalent to ten tablets) was administered by the clinical anesthesiologist as a slurry through the oral gastric tube that was placed after induction of general anesthesia.
Placebo
Participants ingested ten gelatin capsules the night before surgery. On the day of surgery, a second dose of the placebo (equivalent to ten capsules) was administered by the clinical anesthesiologist as a slurry through the oral gastric tube that was placed after induction of general anesthesia.
