Abstract

OBJECTIVE: To report the use of lignocaine and the measurement of its metabolite, monoethylglycinexylidide (MEGX), as a dynamic test of liver function. CLINICAL FEATURES: The conversion of lignocaine to MEGX has been used serially as a test of liver function in a liver transplant recipient for whom retransplantation was necessary because of primary non-function (PNF) of the initial graft. MEGX concentrations were markedly depressed with individual episodes of PNF, cardiac failure and rejection in this patient. CONCLUSION: The test provided useful additional supportive information in assessment of the patient and management of intercurrent problems following liver transplantation.
