Summary
Dry ice can cause oral frostbite, a condition previously unreported. This case highlights the risks of misuse and potential airway complications from this common cryogen.
Area of Science:
- Emergency Medicine
- Toxicology
Background:
- Dry ice (solid carbon dioxide) is a widely available cryogen.
- Improper use of dry ice can lead to frostbite injuries.
- Oral frostbite is a rare but serious complication.
Observation:
- This report details the first documented case of oral frostbite caused by dry ice.
- The patient presented with frostbite of the oral cavity, leading to submandibular and lower lip swelling.
- Clinical features resemble frostbite associated with volatile substance abuse.
Findings:
- Oral frostbite can directly damage oral mucosa and indirectly affect surrounding tissues.
- Edema of the upper airway tract is a potential complication of oral frostbite.
- Severe pharyngeal or laryngeal edema may necessitate tracheal intubation or tracheostomy.
- Steroids and antibiotics may help prevent pharyngolaryngeal edema.
Implications:
- Volatile substance abuse can lead to unexpected medical events.
- Healthcare providers should consider delayed complications from substance abuse.
- Awareness of dry ice risks is crucial for public safety.

01:29Decreased Body Temperature
A decreased body temperature can occur in patients with hypothermia and frostbite. Heat loss with extended cold exposure overpowers the body's ability to create heat, resulting in hypothermia. Core temperature readings help classify hypothermia. Mild hypothermia is temperatures between 32 °C (89.6 °F) and 35°C (95 °F) and is caused by impaired thermoregulation. Moderate hypothermia is temperatures between 28 C (82.4 °F) and 32 °C (89.6 °F) caused by sustained extreme cold exposure, and severe...
01:27Frost Action on Concrete
Concrete structures in cold climates, such as those along roadsides, can retain moisture. This moisture makes them susceptible to frost-related damage when temperatures fall below freezing. Adding moisture worsens the damage during temperature fluctuations, leading to repeated freezing and thawing. De-icing salts, spread over these structures to melt ice, add to the freeze-thaw cycle, and draw even more moisture into the concrete.

02:33Phase Transitions: Sublimation and Deposition
Some solids can transition directly into the gaseous state, bypassing the liquid state, via a process known as sublimation. At room temperature and standard pressure, a piece of dry ice (solid CO2) sublimes, appearing to gradually disappear without ever forming any liquid. Snow and ice sublimate at temperatures below the melting point of water, a slow process that may be accelerated by winds and the reduced atmospheric pressures at high altitudes. When solid iodine is warmed, the solid sublimes...
03:12Freezing Point Depression and Boiling Point Elevation
Boiling Point Elevation
The boiling point of a liquid is the temperature at which its vapor pressure is equal to ambient atmospheric pressure. Since the vapor pressure of a solution is lowered due to the presence of nonvolatile solutes, it stands to reason that the solution’s boiling point will subsequently be increased. Vapor pressure increases with temperature, and so a solution will require a higher temperature than will pure solvent to achieve any given vapor pressure, including one...

01:21Masonry in Cold and Hot Weather Conditions
In cold weather, masonry construction requires specific precautions to ensure mortar does not freeze before curing, as this can significantly weaken its strength and watertightness. Mortar temperature should be maintained between 60°F and 80°F to support proper hydration and curing. Below 40°F, mortar water must be heated, but should not exceed 120°F as high temperatures can reduce mortar's compressive and bond strength.

01:28Cryo-electron Microscopy
Conventional electron microscopy (EM) involves dehydration, fixation, and staining of biological samples, which distorts the native state of biological molecules and results in several artifacts. Also, the high-energy electron beam damages the sample and makes it difficult to obtain high-resolution images. These issues can be addressed using cryo-EM, which uses frozen samples and gentler electron beams. The technique was developed by Jacques Dubochet, Joachim Frank, and Richard Henderson, for...
