Effect of Lidocaine and Epinephrine on Human Erythrocyte Shape and Vesiculability of Blood Cells

Figure 2

Effect of the local anesthetic lidocaine/epinephrine (L/E) on the erythrocyte shape. (a) Blood dissolved in phosphate buffered saline (PBS), (b) blood dissolved in PBS with added L/E (stomatocytosis), (c) echinocytosis was induced by centrifugation of blood dissolved in PBS, and (d) echinocytes dissolved in PBS transformed into discocytes after the addition of L/E to the suspension. Bar = 10 μm.
