Methamphetamine-associated pulseless electrical activity in a young child.

This is a case report of a 19-month-old female who presented to the emergency department in cardiac arrest after methamphetamine exposure. Prior to presentation, she had seizure-like activity and then became unresponsive. On arrival, she had dilated pupils, intermittent clonus, and pulseless electrical activity. She was found to have full thickness circumferential burns of her bilateral lower extremities. She received 12 doses of epinephrine, cardiopulmonary resuscitation, and volume resuscitation after which she had return of spontaneous circulation and was transferred to the intensive care unit on an epinephrine drip. Initial laboratory studies showed a mixed metabolic and respiratory acidosis and hyperglycemia. An initial urine immunoassay for drugs of abuse was negative, however, 5 h later, a second urine immunoassay was positive for amphetamine. The first specimen was also sent for liquid chromatography-mass spectrometry analysis that later returned positive for methamphetamine and amphetamine. In retrospect, the initial urine screen was found to have evidence of amphetamine below the threshold for positivity (500 ng/mL), and the second urine specimen was highly positive, with an amphetamine level of >1450 ng/mL. In this case, what turned out to be a sub-threshold rather than undetectable level was clinically significant, highlighting the challenges of urine screening in cases of suspected poisoning syndromes with atypical presentations. Our case also suggests the possibility of PEA as a presentation of methamphetamine toxicity in a child. Copyright © 2020 Elsevier Inc. All rights reserved.
