概括
这项研究发现,虽然传统的加热方法在麻醉期间最能保持狗的体温,但AVAcore爪子加热装置也有助于减少低温. 在加热技术之间没有观察到麻醉恢复时间的显著差异.
科学领域:
- 兽医麻醉学 兽医麻醉学
- 动物生理学 动物生理学
背景情况:
- 一般麻醉会损害狗的温度调节,增加低温的风险.
- 烂的脚皮肤为缓解麻醉期间低温症的干预提供了潜在的场所.
研究的目的:
- 为了比较一种新型的足部加热装置 (AVAcore) 与常规方法的有效性,并且在麻醉下的狗中保持直肠温度而没有加热.
- 评估不同升温技术和前期治疗对麻醉恢复时间的影响.
主要方法:
- 试点研究涉及用acepromazine (ACE) 或dexmedetomidine (DEX) 预先治疗的狗,诱导用propofol,并维持在isoflurane上.
- 在三个时间段内监测和分析了直肠温度:T0-T15,T15-T30和诱导后>T30分钟.
- 加热方法包括AVAcore设备 (AVA),没有加热 (NONE) 和常规干部加热 (CONV).
主要成果:
- 总的来说,acepromazine (ACE) 导致直肠温度的降低比dexmedetomidine (DEX) 更大.
- 在麻醉>30分钟后,常规升温 (CONV) 显示温度降低最小,而无升温 (NONE) 显示温度降低最大.
- 调节的AVAcore设备 (AVA) 温度下降,性能比没有升温要好,但效率低于CONV. 两组之间没有发现康复时间的差异.
结论:
- 传统的干部加热在狗麻醉期间提供了最稳定的温度调节.
- AVAcore足部加热装置是缓解麻醉犬体低温的可行选择,提供了额外的治疗方法.
- 前期药物选择 (ACE与DEX) 影响温度变化,而DEX通常与更好的温度稳定性有关,特别是在常规变暖时.

Decreased Body Temperature
602
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...

Methods of reducing fever
642
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.

Parenteral Anesthetics: Overview
95
Intravenous anesthetics are drugs administered parenterally to induce anesthesia or sedation. Propofol is a widely used agent formulated as a 1% emulsion in soybean oil, glycerol, and egg phosphatide. It induces rapid anesthesia primarily due to its rapid distribution from the bloodstream to target tissues and is metabolized in the liver. However, it can cause significant pain on injection and hypertriglyceridemia. Fospropofol, a water-based prodrug of propofol, lacks these adverse effects.

Temperature Measurement Sites
1.5K
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...
