Abstract

A quantitative liver test based on the formation of the lidocaine metabolite monoethylglycinexylidide (MEGX), was used to evaluate the effect of hemorrhagic shock at 40 mmHg for 90 min on Sprague-Dawley rats. After 2 h of stabilization, lidocaine was injected (2 mg/kg). A second group received volume resuscitation with Ringer's lactate over 1 h (15 mL/kg) after shock, and after 1 h of stabilization lidocaine was administered. These groups were compared to control animals. Blood samples were drawn at 0 time (baseline), prior to lidocaine injection, and at 10, 15, 30, and 60 min after lidocaine injection. MEGX values in shocked animals were significantly lower than in the control group; in animals receiving volume resuscitation, levels were higher than the shocked animals without resuscitation, but did not reach control levels. Thus, shock produced a significant depression of hepatocyte function, which was partially reversed by Ringer's lactate resuscitation. The MEGX test appears to be a suitable tool for clinical evaluation and therapeutic intervention after shock.
