概括
与普罗波/米达佐拉姆相比,德克斯梅德托米丁 (DEX) 镇静剂并没有显著改变败血性脑病 (SE) 的生物标志物. 然而,DEX在格拉斯哥昏迷表得分较低的患者中显示出降低S100-β水平的潜力.
科学领域:

- 神经科学是一个神经科学.
- 药理学 药理学是指药理学的学科.
背景情况:
- 败血性脑病 (SE) 是重症败血症患者的常见并发症,与高死亡率有关.
- SE病理生理学涉及炎症,常见的镇静剂,如普罗波福和米达佐拉姆,可能会加剧神经元炎症.
- 德克斯梅德托米丁 (DEX) 在临床前败血症模型中显示出抗炎性质.
研究的目的:
- 为了研究基于DEX的镇静对SE生物标志物的影响,在重症败血症患者中.
- 为了比较DEX和propofol/midazolam镇静组之间的血清S100-β水平.
主要方法:
- 试点,开放标签,随机对照试验在一个中心进行.
- 需要机械通风和镇静的成人败血症患者随机分配给DEX或普罗波/米达佐拉姆.
- 在随机化后48小时测量了血清S100-β水平.
主要成果:
- 总体而言,DEX和普罗波/米达佐拉姆组之间的S100-β水平没有显著差异 (p=0.064).
- 在格拉斯哥昏迷尺度≤13的患者中,DEX镇静与显著较低的S100-β水平相关 (p=0.033).
- 在其他SE生物标志物中没有观察到差异.
结论:
- 在机械通风的败血症患者中,基于DEX的镇静剂并没有显著改变S100-β或其他SE生物标志物,而不是与propofol/midazolam相比.
- 低S100-β水平在DEX镇静患者GCS≤13表明潜在的好处需要进一步的研究.

01:24Parenteral Anesthetics: Overview
87
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.

01:21Skeletal Muscle Relaxants: Adverse Effects
316
Skeletal muscle relaxants are widely used for muscle paralysis and relieving pain following any muscle injury or stiffness. However, depending on the drug type, they can have adverse effects that range from mild to severe. Usually, nondepolarizing neuromuscular blockers have minimal side effects. For example, drugs like d-tubocurarine, cisatracurium, and rocuronium cause hypotension, whereas drugs like baclofen, when stopped abruptly, can lead to the recurrence of spastic conditions.

01:19Depolarizing Blockers: Pharmocokinetics
296
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...

01:31Skeletal Muscle Relaxants: Therapeutic Uses
443
Skeletal muscle relaxants are used to relax muscle tone and alleviate painful muscle contractions. However, the choice of skeletal muscle relaxants depends on the duration of the surgical procedure in order to minimize potential side effects. Skeletal muscle relaxants like neuromuscular blocking agents [NMBAs] are commonly employed as adjuvants alongside general anesthetics in clinical settings. NMBAs are also used to maintain controlled ventilation during surgery of the larynx or pharynx...

01:22Stages of General Anesthesia

Various sedation levels offer significant advantages in facilitating procedural interventions for patients undergoing medical or invasive surgical procedures. These levels span from anxiolysis to general anesthesia, providing a spectrum of sedative effects to cater to specific patient needs. Anxiolysis reduces anxiety and is achieved through minimal sedation, enabling patients to remain awake and responsive while feeling more at ease during the procedure. This level can benefit minor...

132
Sedatives and hypnotics encompass a wide range of substances, each with its unique mechanism of action, uses, and potential adverse effects.
Melatonin congeners like ramelteon (Rozerem) and tasimelteon (Hetlioz) selectively bind to melatonin receptors (MT1 and MT2) and thus mimic the actions of melatonin, a hormone that regulates sleep-wake cycles. Tasimelteon is primarily used for non-24-hour sleep-wake disorder, common in blind patients. They are also used to treat conditions like insomnia...
