Hand sanitizer formulations vary by manufacturer and contain different concentrations of ethanol and/or isopropanol, as well as additional potential inactive ingredients such as acetone, 1-propanol, 2-propanol, benzyl alcohol, hydrogen peroxide, glycerin, water, and different perfumes.3,4
Persons who consume hand sanitizers recreationally are often unaware of the large alcohol content by volume that they are consuming. Recreational ingestion of hand sanitizer is believed to be the cause of at least one case of lethal ethanol intoxication. An articlereported a case of a male patient who suffered respiratory arrest after consuming an ethanol-based hand sanitizer.6 This patient was noted to have a serum ethanol of 536 mg/dL after consuming an unknown quantity of a 354 mL container of a 62% ethanol by volume hand sanitizer.6
Institutionalized individuals seeking alcohol through this source have discovered novel ways to yield a stronger product. Through the use of table salt and a cotton sock, it is possible to extract a liquid from a gel hand sanitizer preparation, yielding an alcohol context 30% higher by volume than the parent mixture.7
Alcohol intoxication poses a host of health effects. In nonhabituated individuals, a lethal load of alcohol can be achieved by consuming a volume of as little as 400 mL of an 80% alcohol-based solution.4 Symptoms from ingestion of an alcohol-based liquid hand sanitizer typically appear 1 to 2 hours after ingestion and mirror that of the alcohol toxidrome. Most commonly, this includes nausea, vomiting, epigastric pain, and varying degrees of central nervous system (CNS) depression.4 The life-threatening clinical manifestation of alcohol intoxication includes severe CNS and respiratory depression resulting in respiratory arrest, hypothermia, cardiac dysrhythmias with possible cardiac arrest, hypoglycemia, ketoacidosis, and hypotension.3
How is alcohol-based hand sanitizer ingestion managed?
The management of patients with alcohol-based hand sanitizer ingestion is the same as the management of alcohol ingestion from more socially acceptable sources and is mainly supportive.3,4 These measures are directed at managing the patient’s airway with intubation and mechanical ventilation when appropriate, as well as supportive measures to address any underlying metabolic derangement or hypotension.2 While hemodialysis has been used in some patients who had severe organ dysfunction and did not respond to supportive measures, it is usually not necessary.1,3
Case Conclusion
The patient in this case was subsequently admitted to an intermediate level of care. He did not require intubation or further hemodynamic support during his initial acute intoxication. Later in the patient’s hospital course, he was noted to be in alcohol withdrawal, and proper management was initiated. He also required therapeutic one-to-one supervision after members of the nursing staff observed the patient consuming the hand sanitizer gel present in patient-care areas. He was later seen by psychiatry services. The psychiatrist recommended transfer to an inpatient psychiatric facility upon medical clearance for treatment of his psychiatric illness as well as alcohol dependence.
