Plasma choline concentrations. Plasma choline (µg ml−1) concentration levels are measured for the placebo and choline supplementation cohorts at baseline, intubation, end of surgery, 1 h after surgery, and 24 h after surgery in patients who (a) were treated with succinylcholine and (b) were treated with a non-depolarizer. Baseline plasma choline concentrations are not significantly different between the two groups. Plasma choline concentrations are significantly higher in the choline cohort at all other measurements (P=0.038).
