概括
一个热耐受性测试 (HTT) 运动热中风 (EHS) 恢复需要直肠温度 (TREC). 在这项研究中,非侵入性方法和步态传感器不是TREC的有效替代品.
科学领域:
- 运动医学 运动医学
- 环境生理学环境生理学
- 生物医学工程 生物医学工程
背景情况:
- 耐热测试 (HTT) 对于在运动热中风 (EHS) 后的回归游戏决策至关重要.
- 标准的HTT依赖于直肠温度 (TREC) 和心率 (HR),但TREC通常是临床上禁止的.
- 步行传感器已经成为检测热病的潜在工具,但在HTT期间缺乏对TREC的验证.
研究的目的:
- 评估非侵入性温度部位和步态度指标在标准HTT期间作为TREC的替代品的有效性.
- 为了确定步态变量是否可以准确地反映HTT期间的核心体温变化.
- 在不允许测量TREC的环境中评估HTT替代方法的可行性.
主要方法:
- 18名受试者 (22±2岁) 完成了标准的HTT.
- 同时测量直肠,口腔,听觉,额头和部温度,步态参数和HR每5分钟记录一次.
- 使用斯皮尔曼相关性来分析TREC和步态变量之间的关系;温度位置的有效性是通过TREC的偏差来评估的.
主要成果:
- 所有非侵入性温度位点 (口腔,听觉,额头,下) 显示出显著的偏差,并在测试时间的大部分时间内超过了有效性值 (>±0.27°C).
- 耳道温度偏差为-0.19 ± 0.56°C,而口腔,关和额头温度显示出更大的偏差.
- TREC与步态指标有显著的相关性,包括与冲击 (-0.28) 和冲击g (-0.28) 的负相关性,以及与出行 (0.30) 的正相关性.
结论:
- 直肠温度 (TREC) 仍然是HTT的黄金标准,因为没有一个非侵入性温度部位证明了足够的有效性.
- 某些步态变量显示出在HTT期间跟踪核心温度的潜力,需要进一步研究临床应用.
- 目前的非侵入性温度测量是HTT协议中TREC的不足替代品.

01:14Temperature Measurement Sites
3.2K
A thermometer measures body temperature. The common sites for measuring body temperature are the oral cavity, axillary region, temporal artery, and skin surface, such as the forehead, abdomen, and axilla. True core body temperature is assessed in the rectum, tympanic membrane, pulmonary artery, esophagus, and urinary bladder.
Oral: When assessing oral temperature, the thermometer tip should be placed under the tongue in the posterior sublingual pocket. It offers accurate readings and can be...

11.5K
Rectal temperature measurement is considered the most precise method for assessing core body temperature and typically registers higher than oral temperature. For adults, the rectal thermometer should be inserted 1 to 1.5 inches into the rectum to obtain the most accurate reading.
Follow these steps for rectal temperature assessment:
Step 1: Perform hand hygiene and don clean gloves to prevent cross-infection.
Step 2: Position the patient in a side-lying position to better visualize the rectal...

Here are the steps to accurately measure oral temperature using an electronic thermometer:
Step 1:
Start by practicing proper hand hygiene to prevent the spread of microorganisms.
Step 2:
Take the thermometer out of the charging unit, switch it on, and wait for the ready sign.
Step 3:
Gently slide the probe cover until a click is heard. This simple action prevents cross-contamination and ensures the correct placement of the probe cover.

Body temperature can be assessed using various devices and measured in Celsius or Fahrenheit.
Glass-bulb Thermometer:
Glass-bulb thermometers are hollow glass tubes with a bulb tip containing liquid such as ethanol or mercury. Historically, glass bulb mercury thermometers were the standard device to measure body temperature. Today, mercury thermometers are prohibited in many countries due to the hazardous effects of mercury and the risk of exposure if the glass bulb breaks. In general,...
