Fig. 1From: Lipid emulsion injection-induced reversal of cardiac toxicity and acceleration of emergence from general anesthesia after scalp infiltration of a local anesthetic: a case reportTotal and free concentrations of ropivacaine just before, 30Â min, and 11Â h after lipid rescue. The concentrations at these time points were 540.6, 617.7, and 159.9Â ng/mL (total) and 66, 94.5, and 11.6Â ng/nL, respectively (free). The free fraction ratio (free/total) of ropivacaine increased from 12.2 before lipid rescue to 15.3 after lipid rescueBack to article page
