概括
冰包装在一个体袋设备 (极地生命) 有效地和快速地冷却运动热中风 (EHS) 的患者. 这种方法为紧急医疗服务提供了一个便携式解决方案,可以通过在医院抵达之前实现更快的冷却来降低热中风死亡率.
科学领域:
- 紧急医疗 紧急医疗
- 运动医学 运动医学
- 环境生理学环境生理学
背景情况:
- 冷水浸泡 (CWI) 是降低运动热中风 (EHS) 患者体温的最快方法.
- 治疗延迟和CWI的后勤挑战阻碍了救护车和急救部门 (ED) 的快速冷却.
- 带有CWI的尸体袋 (BAGS) 是有前途的,但在急救机构中存在人员安全和排水等问题.
研究的目的:
- 为了评估冰包装在极地生命 (PLP) 中的有效性,这是一种类似身体袋的设备,用于快速冷却.
- 在没有添加水的情况下,在PLP中使用不同的冰质量来评估冷却速度.
- 确定PLP中的冰包装是否可以克服在医院前和ED环境中与传统CWI相关的挑战.
主要方法:
- 12名受试者 (8名男性,4名女性) 在热中炼,直到直肠温度 (TREC) 达到≥39.75°C.
- 被试者被放置在PLP中,并添加大约9公斤 (小),27公斤 (中等) 或53公斤 (大) 的冰块.
- 冷却继续,直到TREC达到38.25°C,并测量了冷却速率和融水体积.
主要成果:
- 结直肠温度 (TREC) 的降温速度随着冰质的增加而显著增加 (小:0.15°C/分钟;中:0.19°C/分钟;大:0.27°C/分钟;P<0.001).
- 产生的融水量极小,体积从3.8L (小) 到5.3L (中) 和4.9L (大) 之间.
- 在三个冰块之间没有观察到融化水体积的显著差异 (P = 0.07).
结论:
- 在PLP中的冰包装为运动热中风 (EHS) 患者提供了快速冷却.
- PLP的可移植性和有效性解决了救护车和ED中CWI的挑战.
- 这种方法有可能通过在运输过程中及时冷却来降低EHS的发病率和死亡率.

Methods of reducing fever
1.2K
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.

Decreased 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...

Increased Body Temperature
6.4K
A body temperature above 38°C (100.4 °F) is known as fever or pyrexia, and a person with fever is termed 'febrile.' Typically, the hypothalamus, a part of the brain that acts as the body's thermostat, regulates body temperature through a thermoregulatory setpoint. It receives signals from cold and warm thermal receptors throughout the body and adjusts the body's temperature accordingly. Fever occurs when this hypothalamic setpoint is altered, usually in...

Homeostatic Imbalances in Body Temperature
4.3K
Hyperthermia occurs when the body's temperature becomes unusually high, often due to heat exposure, intense physical activity, or certain illnesses. This condition can create a dangerous cycle where elevated body temperature increases the metabolic rate, generating more heat and potentially leading to organ failure and brain damage. A severe form of hyperthermia, called heat stroke, can raise body temperature to life-threatening levels. Fever, on the other hand, is a controlled form of...

Pharmacologic intervention is crucial in treating cardiac arrest patients during ACLS or Advanced Cardiovascular Life Support. The ACLS algorithms guide the administration of specific drugs based on the patient's cardiac arrest rhythm, which includes pulseless ventricular tachycardia (VT), ventricular fibrillation (VF), asystole, and pulseless electrical activity (PEA).EpinephrineIndication: Epinephrine is the first-line drug for all cardiac arrest rhythms.Mechanism of Action: Epinephrine...
