Death caused by perioperative fasting and sedation in a child with unrecognized very long chain acyl-coenzyme A dehydrogenase deficiency.

An adopted 3(1/2)-year-old girl with no prior medical problems died after a routine dental procedure. More than 2 years later, acylcarnitine analysis of dried blood found on her bedding revealed she had very long chain acyl-coenzyme A dehydrogenase (VLCAD) deficiency. Perioperative oral fasting, without intravenous administration of glucose, may be detrimental to children with certain metabolic and endocrine disorders. Newborn screening by tandem mass spectrometry will detect disorders of fatty acid oxidation such as VLCAD and allow early and preventive treatment.
