A Case of Transient Hyperlactatemia Induced by Intravenous Glycerol Administration in a Patient With Brain Trauma.

Elevated lactate levels are associated with a poor prognosis in patients with sepsis and shock. Intravenous glycerol administration is often used in Japan to treat patients with acute stroke or brain trauma, but such treatment can cause elevated lactate levels. We experienced a case of transient hyperlactatemia induced by intravenous glycerol administration in a patient with brain trauma. A 74-year-old woman underwent decompressive craniotomy because of loss of consciousness and brain edema. Glycerol was administered after the operation for management of the brain edema. Although the patient's hemodynamics remained stable, her lactate level decreased and increased repeatedly. We recognized that the elevation in her lactate level was associated with the administration of intravenous glycerol. This case suggests that intravenous glycerol administration can induce transient hyperlactatemia.
