Hand Sanitizers and Alcohol Abuse: A Dangerous Cocktail

Since the COVID-19 pandemic, alcoholic hand sanitizers have become widely accessible nationwide. They can pose a problem, especially for emergency departments, when alcohol-dependent patients start drinking them. One example that demonstrates the challenge of diagnosing alcohol abuse is the medical history of a young malingerer, as reported by Mahmoud El Hussein, MD, and colleagues from Hôpital Lariboisière in Paris, France.

Presentation and History

A 26-year-old man presented with severe abdominal pain at the emergency department. Upon arrival, he was hemodynamically stable but nervous and verbally aggressive at times. The patient reported no relevant preexisting conditions and was not taking any medications.

Findings

Upon initial physical examination, the patient had a soft, diffusely tender abdomen; tachycardia; and notably poor hygiene. The patient was afebrile. An ECG confirmed the tachycardia but showed no signs of ischemia. Blood work, except for slightly elevated liver values, did not reveal any abnormalities, particularly ruling out bleeding or kidney disease.

A urease rapid test to rule out kidney stones also showed no pathologic findings. In consultation with the surgical department, a CT scan of the abdomen was performed to rule out organ perforation, volvulus, or mesenteric ischemia. Only signs of fatty liver were found.

A Neighbor’s Tip

During all examinations, the patient’s abdomen was repeatedly palpated to promptly detect signs of an acute abdomen. However, there was never any defense tension at any point.

Intravenous analgesics and proton pump inhibitors (ie, paracetamol, phloroglucin, and pantoprazole) did not relieve the patient’s symptoms. Morphine was administered intravenously for sedation.

Only after a frustrating diagnostic process did a neighbor of the patient inform a nurse that he suspected the patient of stealing and consuming hand sanitizer. With the patient’s consent, a blood alcohol test was performed, revealing a blood alcohol concentration of 0.2% (2 g/L). A urine test, also conducted with the patient’s consent, tested positive for tetrahydrocannabinol. Additional tests showed the following results:

• Venous pH: 7.29 (normal: 7.32-7.38)
• Anion gap (mEq/L): 14 (normal: 3-9)
• Ketone bodies (mmol/L): 0.2 (normal: < 0.6)
• Calculated serum osmolality (mOsm/kg): 292 (normal: 285-295)
• Measured serum osmolality (mOsm/kg): 320 (normal: 285-295)
• Osmolality gap (mOsm/kg): 2 (normal: < 10)

The patient was informed of the test results and confessed to feigning abdominal pain. He was dependent on alcohol and experiencing withdrawal symptoms. The patient had stolen seven 475-mL bottles of hand sanitizer and consumed one and a half in the past 4-6 hours. According to the authors, the sanitizer consisted of 80% ethanol, 1.45% glycerol, and 0.13% hydrogen peroxide.

Discussion

In Germany, alcohol consumption results in approximately €57 billion in direct economic costs annually, according to data from the Federal Ministry of Health. In 2021, about 7.9 million people aged 18-64 years consumed alcohol in a risky manner (approximately 9.6% of the German population). About 9 million people (approximately 11%) were classified as alcoholics.

The authors of the case report pointed out that those in the advanced stages of alcohol addiction often consume any alcoholic liquid they can access. This includes alcoholic hand sanitizers commonly used in hospitals. Therefore, staff in emergency departments, where potential abusers encounter a wide range of potential abuse items, should exercise caution.

Although hand sanitizers are mainly composed of ethanol, they may also contain isopropanol, methanol, or acetone. Methanol poisoning can cause abdominal pain, visual disturbances, central nervous system damage, and death. Other alcohols such as ethylene glycol, commonly found in antifreeze, can distort blood values (lactate) and complicate a correct diagnosis.

Physicians working in emergency departments should proceed with caution when suspecting alcohol abuse. Questioning the patient’s environment and determining additional laboratory parameters (such as osmolality gap in the case report) can help unmask substance abuse if it is in doubt.
