Clinical Summary

This 45-year-old back female was involved in a house fire which killed her husband. Upon admission to a local emergency room she was found to have approximately 80% body surface area burns including 1st, 2nd, and 3rd degree burns. Burns were most severe around the head and neck. The patient was intubated and transferred to a tertiary care center. Upon arrival, the patient had a blood pressure of 71/25 mmHg, a heart rate of 121, and was responsive to deep pain but had few spontaneous movements. Both eyes were swollen shut, her nasal hairs were singed, and carbonaceous deposits were present in her nares, throat, and posterior pharynx. Despite aggressive fluid resuscitation and ventilatory support, she remained hypotensive, and became progressively hypoxemic and hypercapnic until she died approximately eight hours after the fire.

Autopsy Findings

The degree and severity of body surface burns were documented. Carbonaceous material was noted in the throat and posterior pharynx as well as in the trachea and main stem bronchi. The liver was soft, yellow and greasy. Results of premortem blood work showed a blood alcohol level of 147 mg/dLA blood alcohol level over 100 mg/dL is considered legally drunk..
