- 代谢过程中的代谢.
- 麻醉学 麻醉学
背景情况:
- 大脑的新陈代谢依赖于葡萄糖和类来获得能量.
- 失调的大脑新陈代谢与外科手术期间的神经认知障碍和麻醉诱导的突发抑制有关.
研究的目的:
- 研究睡眠和麻醉期间大脑代谢物和神经生理学之间的关系.
- 比较标准饮食 (SD) 和性饮食 (KD) 对大脑活动的影响.
主要方法:
- 在SD和KD下的老鼠中测量了前额叶皮层的葡萄糖,乳酸和脑电图.
- 进行了sevoflurane麻醉,并评估了爆发抑制.
- 使用腺A1受体对抗剂 (DPCPX) 来评估子活性.
主要成果:
- 与睡眠相比,sevoflurane会导致葡萄糖和乳酸的波动更大.
- 与SD相比,性饮食 (KD) 降低了爆发抑制比率,并增加了运动丧失的时间.

Inhalational Anesthetics: Overview
162
Inhalation anesthetics are drugs that induce general anesthesia upon inhalation. They work by increasing the sensitivity of GABAA receptors or inhibiting NMDA receptors, leading to a decrease in central nervous system activity. The depth of anesthesia can be rapidly adjusted by changing the concentration of the inhaled gas. Some common examples of inhalational anesthetics include volatile liquids like isoflurane, desflurane, sevoflurane and gases like xenon and nitrous oxide. Isoflurane, a...

Depolarizing Blockers: Pharmocokinetics
300
Depolarizing blockers are administered through intravenous injection. Succinylcholine is the most common choice of depolarizing blockers in emergency clinical practices. Although they have a rapid onset, they readily diffuse away from the motor end plate into the extracellular fluid. They are metabolized by enzymes such as liver butyrylcholinesterase and plasma pseudocholinesterases. This produces a short duration of action, typically 5-10 minutes long, unlike nondepolarizing blockers, which...
