Objectives:
A 30-year-old patient presented with hallucinations and profound shock. He was initially misdiagnosed as having severe sepsis; once ingestions were considered, he was diagnosed as potentially having arsenic toxicity.
Summary:
The clinical story reveals many instructional lessons that could aid in the evaluation and management of future patients. This man presented with large amounts of blue crystals around his nose and lips from inhaling and eating boric acid (an ant poison) so he could, as he put it, kill the ants "pouring into my mouth and nose and up into my brain." His profound pseudosepsis and sustained delirium were induced by co-ingestion of methamphetamine and a large quantity of boric acid. Delirium is a form of acute brain dysfunction that often is multifactorial in critical illness and, when seen in septic shock, is associated with prolonged mechanical ventilation, increased length of hospital stay, medical costs, higher mortality, and long-term cognitive impairment resembling dementia. Pseudosepsis is a noninfectious condition most commonly seen with ingestions such as salicylate (aspirin) toxicity.
Conclusions:
This report emphasizes the need to recognize agents that contain boric acid as an etiology of unexplained delirium and profound shock.
Insights
Boric acid ingestion can mimic severe sepsis, causing profound shock and delirium. Early recognition of boric acid toxicity is crucial for accurate diagnosis and effective patient management.
Area of Science:
- Toxicology
- Emergency Medicine
- Critical Care
Background:
- Delirium and shock are critical conditions often associated with sepsis.
- Pseudosepsis, a non-infectious condition mimicking sepsis, can be caused by toxic ingestions.
Observation:
- A patient presented with hallucinations and shock, initially misdiagnosed as severe sepsis.
- The patient had ingested boric acid (ant poison) and methamphetamine, leading to pseudosepsis and delirium.
- Blue crystals around the nose and lips indicated boric acid exposure.
Findings:
- Boric acid co-ingestion with methamphetamine induced profound pseudosepsis and sustained delirium.
- Boric acid toxicity can present with symptoms mimicking severe sepsis, complicating diagnosis.
Implications:
- Recognizing boric acid as a cause of unexplained delirium and shock is vital.
- This case highlights the importance of considering toxic ingestions in patients with sepsis-like presentations.
- Awareness of boric acid's potential toxicity can improve diagnostic accuracy and patient outcomes.
