The client: A 34-year-old guy in Mexico
The signs: Within seconds of consuming a “smoky” liquor at a bar, the guy felt an extreme discomfort in his stomach.
The client reported feeling pain and inflammation when the medical professionals touched his abdominal area in 4 locations. This exposed that the discomfort was prevalent instead of localized to one organ as is frequently the case with conditions like appendicitis
The guy informed his physicians that the beverage he had actually taken in had actually been instilled with liquid nitrogen, and the physicians presumed that the compound burst the male’s stomach. When liquid nitrogen warms and converts to a gas, it broadens in volume by approximately 700 timesOwing to the huge distinction in temperature level in between the liquid, at minus 351 F (minus 196 C), and the male’s body, the compound might have quickly swelled into a gas, the physicians composed in a report of the guy’s caseand therefore popped the stomach like an overinflated balloon.
To examine if there was a perforation in the guy’s stomach, the medical professionals listened for indications of air while tapping on his abdominal area. Some locations of the abdominal area, such as the stomach, usually consist of air and produce a high-pitched, “tympanic” noise when tapped. By contrast, more strong or liquid-containing organs, like the liver sitting on top of the stomach, produce a low-pitched, “dull” noise. In this client, nevertheless, the whole abdominal area was tympanic, consisting of the area above the stomach.
The medical diagnosis: Next, the physicians observed the client’s soft tissue utilizing CT scans. From those scans, they found a layer of caught nitrogen gas in the client’s abdominal area, simply above his stomach and listed below his lungs– a condition referred to as pneumoperitoneum. This validated that the gas had actually burst the male’s stomach and gathered above it.

The treatment: The physicians made a little, keyhole cut in the client’s abdominal areas that launched the caught nitrogen gas. They then placed a laparoscope– a thin tube with an electronic camera– through the key-hole and into the stomach to discover and fix the perforation. They sutured and sealed the 1.2-inch-wide (3 centimeters) hole, utilizing a piece of fatty tissue from somewhere else in the male’s abdominal area.
The client made a fast healing and was released 3 days later on, after he showed he might endure a liquid diet plan, the physicians kept in mind in the report.
What makes the case special: Breaking the stomach, liquid nitrogen that gets taken in before it totally vaporizes from food and beverage can trigger irreversible cold burns in the body, as the compound freezes water within human cells and damages tissue.
Thankfully, the client did not experience any cold burns in his mouth, esophagus or stomach. The medical professionals thought this was thanks to the “Leidenfrost effect,” a physical phenomenon that explains how a liquid acts when it fulfills a surface area significantly warmer than its boiling point. The outer layer of the liquid immediately vaporizes, briefly protecting the warm surface area (in this case, human tissue) from the staying cold liquid. This insulating gas layer might describe why the liquid nitrogen didn’t burn the male while travelling through his craw.
Liquid nitrogen is typically utilized in cookingFlash-freezing meat with this compound protects its protein structure and locks in wetness more effectively than other freezing approaches do. It can likewise maintain fats in seafood and assist it keep its taste. By the time these food products struck the supper table, they are safe to take in due to the fact that the nitrogen has actually totally bubbled off.
Garnishing food and beverage with liquid nitrogen for its smoky, theatrical look can be harmful if restless gourmands take in those products before the liquid has actually entirely vaporized. It’s finest to wait up until the cloud dissipates. Frequently liquid nitrogen is utilized to develop a smoke impression near food, however not within it, decreasing the danger of injury.
