Summary
Cryogenic burns from coolant gases are rare but can cause severe hand injuries. Prompt treatment in a specialized burn center is crucial for optimal recovery and function.
Area of Science:
- Occupational medicine
- Burn surgery
- Toxicology
Background:
- Cryogenic burns from coolant gases in refrigerators and air conditioners are infrequently reported.
- This study investigates occupational factors, injury patterns, and treatments for these rare injuries.
Purpose of the Study:
- To analyze occupational circumstances leading to cryogenic burns.
- To identify common injury sites, involved chemicals, and effective treatment strategies.
Main Methods:
- Retrospective analysis of 15 burn cases from March 2015 to March 2019 at a tertiary burn center in India.
- Evaluation of demographic details, chemical agents, and burn characteristics.
Main Results:
- All 15 cases involved hand injuries.
- Initial management included dressings and nonoperative care.
- One patient needed debridement, and another required skin grafting, with all achieving satisfactory hand function.
Conclusions:
- Cryogenic burn etiology varies, with exposure time being key to severity.
- Specialized burn center treatment is recommended post-exposure.
- Understanding burn pathophysiology and management is vital to prevent adverse outcomes.

01:22Burn Injuries
3.6K
Burn injuries occur when the skin and underlying tissues are damaged due to exposure to heat, electricity, chemicals, radiation, or friction. They can vary in severity, from minor superficial burns to severe deep burns that can be life-threatening.
The damage results in the death of skin cells, which can lead to a massive loss of fluid. Dehydration, electrolyte imbalance, and renal and circulatory failure follow, which can be fatal. Burn patients are treated with intravenous fluids to offset...

01:29Decreased Body Temperature
829
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...

The signs and symptoms of fever include hot and dry skin, flushed face, thirst, muscle aches, anorexia, headache, tachycardia, tachypnea, and fatigue. Elevated body temperature is reduced using two methods: pharmacological and nonpharmacological. Proper identification and treatment of the root cause of a fever is of utmost importance.

01:20Inhalational Anesthetics: Overview
700
Inhalation anesthetics are drugs that induce general anesthesia upon inhalation. They work by increasing the sensitivity of GABAA receptors or inhibiting NMDA receptors, leading to a decrease in central nervous system activity. The depth of anesthesia can be rapidly adjusted by changing the concentration of the inhaled gas. Some common examples of inhalational anesthetics include volatile liquids like isoflurane, desflurane, sevoflurane and gases like xenon and nitrous oxide. Isoflurane, a...

1.1K
Flame photometry, also known as flame emission spectrometry, is a technique used for the qualitative and quantitative analysis of elements present in a sample using a flame as the source of excitation energy. The concept of flame photometry was realized in the early 1860s by Kirchhoff and Bunsen, who discovered that specific elements emit characteristic radiation when excited in flames. The first instrument developed for this purpose was used to measure sodium (Na) in plant ash using a Bunsen...
