Core Viewpoint - The increasing use of heating devices such as electric blankets, warmers, hot water bags, and small heaters during winter poses a risk of low-temperature burns, particularly among vulnerable populations like the elderly, children, and diabetic patients [1] Group 1: Definition and Characteristics of Low-Temperature Burns - Low-temperature burns occur when skin is in prolonged contact with heat sources ranging from 41°C to 60°C, leading to deeper tissue damage despite milder pain compared to high-temperature burns [2] - These burns can be misdiagnosed as ordinary redness, delaying treatment and potentially resulting in scarring or chronic ulcers [2] Group 2: Vulnerable Populations - Elderly individuals may not sense temperature changes due to skin aging and reduced sensitivity, making them more susceptible to burns [3] - Diabetic patients often experience peripheral neuropathy, which diminishes their ability to perceive heat, increasing their risk of injury [3] - Infants and young children, due to their delicate skin and inability to communicate discomfort, are also at high risk [3] - Individuals with neurological impairments, those under anesthesia, intoxicated, or sedated may not recognize the danger of prolonged exposure to heat sources [3] Group 3: Safe Heating Practices - Common practices that can lead to low-temperature burns include prolonged exposure to heating devices on the same body part, high temperatures from electric blankets, and inadequate use of hot water bags [4] - Recommendations for safe use include keeping hot water bag temperatures below 50°C, using towels as barriers, and ensuring electric blankets are turned off after preheating [4] - Maintaining a safe distance from heaters and avoiding prolonged exposure to the same area are crucial [4] - Regular skin checks for vulnerable individuals using heating devices are advised to catch early signs of burns [4] Group 4: Purchasing Guidelines for Heating Devices - When purchasing heating devices, it is essential to choose products with 3C certification, temperature control protection, and automatic shut-off features, while avoiding outdated or damaged items [5] Group 5: First Aid for Low-Temperature Burns - Immediate actions for suspected low-temperature burns include removing the heat source and cooling the affected area with running water for 15-30 minutes [6] - It is important to avoid home remedies and seek professional medical help, especially if blisters or significant skin changes occur [6] - Emphasizing safety during winter heating is crucial to prevent minor injuries from escalating into serious health issues [6]

Core Viewpoint - The article highlights the rising cases of low-temperature burns in Fuzhou due to improper use of heating devices during the recent cold snap, particularly among young people who often underestimate the risks associated with such injuries [2][4]. Group 1: Incident Reports - A student named Xiao Li suffered a third-degree burn on his left calf after using a hot water bottle for warmth while sleeping, leading to severe infection and requiring professional treatment [1][3]. - The hospital's wound repair clinic has seen over ten cases of low-temperature burns in just one week, with a significant number of patients being young adults, contrary to the previous belief that such injuries primarily affected the elderly [4]. Group 2: Medical Insights - The attending physician explained that low-temperature burns can be insidious, as the initial pain is minimal, allowing for deep tissue damage to occur without immediate awareness [3][4]. - Symptoms of low-temperature burns include initial redness and swelling, followed by numbness and the formation of dark blisters, which can lead to skin necrosis and infection if not treated promptly [4]. Group 3: Safety Recommendations - To prevent low-temperature burns, the physician advises the public to follow four safety guidelines when using heating devices: 1. Ensure heat sources are insulated with 1-2 layers of clothing and avoid direct skin contact, moving the device periodically, and limiting contact to no more than 30 minutes [5]. 2. Maintain water temperature in hot water bottles below 50°C and only preheat electric blankets before sleep, ensuring they are turned off afterward [5]. 3. Vulnerable populations, such as the elderly and those with diabetes, should use lower temperatures (≤40°C) and check their skin regularly [6]. 4. Avoid sleeping with heating devices to reduce the risk of burns due to decreased skin sensitivity during sleep [6].

Core Viewpoint - The article highlights the increasing incidence of a skin condition known as "fire-induced dermatitis" or "fire-induced erythema" during winter, attributed to prolonged exposure to heating devices such as electric blankets and heaters [1][3]. Group 1: Condition Overview - Fire-induced erythema is characterized by persistent red spots and capillary expansion due to prolonged exposure to external heat sources, commonly seen in areas frequently in contact with these heat sources [1][3]. - Patients like Xiao Lin have reported symptoms including localized skin dryness, itching, and pain, with the condition being diagnosed by dermatologists [1][2]. Group 2: Medical Insights - Dr. Xu Gejiao explains that skin is highly sensitive to temperature, and exposure to heat sources at 45-50°C can lead to capillary expansion and subsequent pigment deposition in the skin, resulting in discoloration [3][4]. - The discoloration often appears as net-like or patchy brownish-purple spots, typically in areas that frequently contact heat sources, and may initially present with mild redness and capillary expansion [2][3]. Group 3: Recommendations - It is advised to maintain a safe distance from heating devices and to avoid direct skin contact, using towels or heat-resistant pads as barriers [4]. - Continuous use of heating devices should not exceed 30 minutes, and individuals experiencing unexplained skin discoloration related to heating device use should seek medical attention promptly [4].

Group 1: Types of Burns - Low-temperature burns are a significant concern in winter, caused by prolonged contact with objects slightly above body temperature, leading to deeper skin damage [3][4]. - Contact burns occur suddenly when children touch high-temperature objects, with common sources including heating devices and hot liquids [5][6]. Group 2: Risk Scenarios - High-risk scenarios for low-temperature burns include prolonged contact with heating pads, electric blankets, and direct skin contact with heat sources [4]. - Common sources of contact burns include household heating devices, hot water pipes, and kitchen items like hot pots and tea cups [5][6]. Group 3: Prevention Strategies - To prevent low-temperature burns, parents should use protective coverings for heating devices and ensure they are not in direct contact with children's skin [7]. - For contact and hot water burns, physical barriers and proper placement of hot items are crucial, along with supervision during cooking and bathing [7].
