概括

在短时间间隔的手术中重复使用雷米芬坦尼尔会使疼痛敏感性恶化. 这种阿片类药物诱导的过敏症与脊髓中α-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid受体 (AMPAR) 活性增加有关.

科学领域:

麻醉学麻醉学
疼痛研究疼痛研究
神经科学是一个神经科学.

背景情况:

在外科手术中使用的雷米芬坦尼尔可能会导致术后的过敏症.
雷米芬坦尼尔对后续手术在短时间内产生的影响尚不清楚.

研究的目的:

在Remifentanil止痛剂下进行两次手术后调查疼痛值.
检查alpha-amino-3-hydroxy-5-methyl-4-isoxazolepropionic酸受体 (AMPARs) 在这个过程中的作用.

主要方法:

大鼠接受了两次雷米芬坦尼尔注射与脚部切口,隔7天.
评估了机械退出值 (PWTs) 和热退出延迟 (PWLs).
记录的C纤维唤起了场潜力,分析了树突脊柱形态,并使用了一种AMPAR抑制剂 (NASPM).

主要成果:

与第一个相比,第二次雷米芬坦尼尔治疗导致较低的PWTs和PWLs.
观察到C纤维唤起潜力的增加和树突性脊柱变化.
纳斯普缓解了雷米芬坦尼尔诱导的过敏症,并逆转了脊柱长期增强.

结论:

在重复手术模型中,重复的雷米芬坦尼尔给药会增强阿片类药物诱导的过敏症.
这种过敏缓解原始化与高调节的脊柱AMPAR贩运有机联系.

关键词:

在AMPA受体上,AMPA受体是过高气质症是一种超高气质症.这是一种阿片类阿片类药物.雷米芬坦尼尔的使用方法重新启动的运行情况.突触性可塑性突触性可塑性

Analgesia and Pain Management

Analgesia and Pain Management

Pain is critical to various clinical pathologies, provoking an urgent need for effective management. Pain, whether acute or chronic, is a complex neurochemical process. Its alleviation depends on the type, with nonopioid analgesics effective for mild to moderate pain, such as musculoskeletal or inflammatory pain, while neuropathic pain responds best to anticonvulsants, tricyclic antidepressants, or serotonin/norepinephrine reuptake inhibitors. For severe acute or chronic pain, opioids may be...

Opioid Analgesics: Synthetic and Semisynthetic Opioids

Synthetic and semisynthetic opioids are pivotal in pain management and tackling opioid addiction. Semisynthetic opioids, including morphinans (morphine derivatives), oxycodone, oxymorphone, hydrocodone, and hydromorphone, have improved pharmacokinetic profiles compared to morphine. Additionally, heroin and 6-MAM (6-Monoacetylmorphine) show better CNS penetration than morphine due to heightened lipid solubility. Hydromorphone, a potent opioid, undergoes hepatic metabolism to form the active...
