Figure 1. Individual plasma-concentration time curves for the cis-trans and the trans-trans isomers of mivacurium in patients after discontinuation of a mivacurium infusion. Breaks in the lines are a result of missing data points because of difficulty obtaining the plasma sample from the venous catheter. One patient in the spontaneous recovery group (patient #5) was eliminated because of injection into the mivacurium-containing intravenous line at the time of discontinuation of the infusion. The plasma concentration reported at 0 min is the baseline plasma concentration during the infusion.
