Insights
A 2-year-old girl died from a fatal fentanyl patch intoxication after her grandmother mistakenly applied it to a knee abrasion. This preventable tragedy highlights the need for better education on potent opioid handling.
Area of Science:
- Toxicology
- Pediatric Medicine
- Forensic Science
Background:
- Transdermal fentanyl patches are potent analgesics used for chronic pain management.
- Accidental exposure, especially in children, can lead to severe toxicity due to rapid absorption.
- Superficial abrasions can compromise the skin barrier, increasing absorption rates.
Observation:
- A 2-year-old child presented with fatal intoxication after a transdermal fentanyl patch was applied to a superficial knee abrasion.
- Autopsy revealed cerebral and pulmonary edema, liver congestion, and regurgitation of stomach contents.
- Toxicology confirmed fentanyl presence in blood, urine, liver, and kidney.
Findings:
- The grandmother mistakenly applied a fentanyl patch instead of a bandage to the child's knee injury.
- Postmortem fentanyl concentrations indicated a fatal level of intoxication in the child.
- The superficial abrasion facilitated rapid absorption of the potent opioid.
Implications:
- This case underscores the critical need for increased public awareness and education regarding the safe storage and handling of transdermal fentanyl patches.
- Stricter regulations for prescribing and dispensing potent analgesics are necessary to prevent accidental pediatric exposures.
- The findings contribute to understanding postmortem fentanyl concentrations in pediatric fatal intoxication cases.
Abstract:
We present a case of fatal intoxication by the application of a transdermal fentanyl patch upon a superficial bleeding abrasion of a 2-year-old girl. The grandmother discovered the body of the child in bed at approximately 7 a.m. External examination revealed a properly developed, nourished, and hydrated child, with some vomit in the nostrils and inside the mouth. There was no evidence of trauma besides small contusions and abrasions on the knees, with a patch placed over the largest abrasion. Closer inspection revealed that this was transdermal fentanyl patch. Internal examination and microscopic analysis revealed regurgitation of stomach content, cerebral and pulmonary edema, and liver congestion. Toxicology analysis revealed trace levels of fentanyl in the blood just above the limit of detection (2 ng/mL), while concentrations in the urine, liver, and kidney were approximately 102, 28, and 10 ng/mL, respectively. Investigation discovered that the child injured her knee while playing the evening before. The grandmother applied the patch to cover the injury, unaware that she had used a fentanyl transdermal patch instead of simple band-aid. Although fatal intoxications are uncommon among young children in high-income countries, it is of major interest to raise awareness of such events especially since a great majority of these are preventable. The presented case points at the need for more thorough education of users and more strict rules in prescribing and handling of this potent medicine. As well, we find this case to be a useful contribution to the evaluation of postmortem fentanyl concentrations in fatal intoxication in a small child.
