Death After Poison Ivy Smoke Inhalation

Area of Science:

• Toxicology
• Environmental Health
• Pulmonology

Background:

• Urushiol, the allergen in poison ivy (Toxicodendron radicans), typically causes type I and III hypersensitivity reactions, primarily skin conditions.
• While rare, systemic effects beyond cutaneous symptoms from urushiol exposure can occur.

Purpose of the Study:

• To report the first documented cases of mortality resulting from respiratory exposure to urushiol smoke.
• To alert clinicians and forensic pathologists to the potential for severe morbidity and mortality from burning poison ivy.

Main Methods:

• Case report of two unrelated individuals who experienced cardiopulmonary arrest after inhaling smoke from burning poison ivy.
• Review of clinical history, circumstances of exposure, and autopsy findings.

Main Results:

• Both cases presented with cardiopulmonary arrest following smoke inhalation from burning poison ivy.
• Autopsy findings were consistent with urushiol smoke inhalation contributing to or causing death.

Conclusions:

• Urushiol smoke inhalation can lead to fatal outcomes, including cardiopulmonary arrest.
• This study underscores the significant risk associated with burning poison ivy and the potential for severe systemic toxicity.
