case_images: Fig. 2. Two grams of magnesium sulphate was administered intravenously, after which sinus rhythm was restored. Four hours later, she had complete loss of circulation, after which cardiopulmonary resuscitation was initiated according to protocol.
case_images: a Showing serum drug serum levels of fluoxetine(black triangles), norfluoxetine (black circles), and the combined serum concentrations of both fluoxetine and norfluoxetine (black squares). b Showing drug serum levels of risperidone (black triangles), 9-OH-risperidone (black circles), and the combined concentrations of both risperidone and 9-OH-risperidone (black squares).
