概括
红外摄像头显示表面温度恢复模式类似于新生猪的直肠温度. 然而,显著的变化意味着表面温度在生产环境中并不能可靠地取代直肠温度.
科学领域:
- 动物科学动物科学
- 身体生理学 身体生理学
- 热调节 热调节 热调节
背景情况:
- 新生猪在代谢上是不成熟的,容易发生快速的温度波动.
- 准确的温度监测对于小猪的生存和福利至关重要.
- 之前的研究表明,红外热学在老猪中具有前途.
研究的目的:
- 为了比较新生猪的直肠温度与表面温度 (红外摄像头).
- 为了评估表面温度作为直肠温度的替代品的适用性.
- 评估不同出生体重小猪的温度恢复模式.
主要方法:
- 在48只小猪 (出生体重≤1.2公斤) 中,直肠和表面温度在出生后3分钟内和多次间隔至24小时内被记录下来.
- 小猪根据出生体重 (BWC1,BWC2,BWC3) 和1.25小时后的直肠温度 (RC1,RC2,RC3) 分类.
- 红外摄像头测量了耳朵底部的表面温度.
主要成果:
- 在出生后的前24小时内,表面温度表现出类似于直肠温度的恢复模式.
- 在表面和直肠温度之间观察到显著和可变的差异.
- 这些差异表明,表面温度不适合替代直肠温度测量.
结论:
- 虽然表面温度趋势反映了小猪的直肠温度恢复,但这种可变性太高,无法用于可靠的生产.
- 直肠温度仍然是新生猪体温度评估的黄金标准.
- 可能需要进一步的研究来完善新生猪的非侵入性热像技术.

Assessing Body Temperature - Rectal
4.4K
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...

Temperature Measurement Sites
1.7K
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...

Assessing Body Temperature - Oral
748
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.
Step 4:
Instruct the patient to open their mouth and place...
