概括
一种新,TAT-PHLPP9c,在因无脉动电活动而导致突然心脏骤停的猪模型中显著改善了全神经功能生存率. 这种是作为一个在内CPR药理学剂的有希望.
科学领域:
- 心脏病学 心脏病学
- 紧急医疗 紧急医疗
- 药理学 药理学是指药理学的学科.
背景情况:
- 对于突然心脏骤停 (SCA) 的心肺复苏 (CPR) 的结果仍然不理想,特别是对于无脉动电活动 (PEA) 停止.
- 内CPR冷却比复苏后冷却更有效,并且与增加的蛋白质激酶B活性有关.
- 开发了一种新型,TAT-PHLPP9c,用于调节蛋白激酶B活性.
研究的目的:
- 调查TAT-PHLPP9c在PEA停止后改善存活率和神经学结果的intra-CPR管理的有效性.
- 测试假设TAT-PHLPP9c增强了猪模型中PEA诱导的SCA的结果.
主要方法:
- 24只母猪通过气球导管膨胀诱导PEA停止.
- 在心肺复苏期间,动物接受了标准的先进生命支持与上腺素 (控制) 或上腺素加7.5 mg/kg TAT-PHLPP9c.
- 神经功能在自发循环恢复后24小时被评估.
主要成果:
- 虽然自发循环的恢复在两组之间没有显著差异 (8/12控制对比12/12;P=0.093),但完全完整的神经生存率在组 (0/12控制对比11/12;P<0.00001) 中显著更高.
- 使用TAT-PHLPP9c显著增加了心肌中尼古丁胺胺氨基二核酸 (NAD+) 水平.
- 该对逮捕后的神经恢复产生了强烈的积极影响.
结论:
- 在心肺复苏期间给TAT-PHLPP9c显著改善了猪模型PEA诱导的SCA中具有完整神经功能的生存率.
- 酸TAT-PHLPP9c显示出作为一种新型药理学剂的潜力,可用于CPR内部使用.
- 通过TAT-PHLPP9c对蛋白激酶B的向调节可能是改善SCA结果的可行策略.

Depolarizing Blockers: Pharmocokinetics
317
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...

Heart Failure Drugs: Inotropic Agents
564
Positive inotropic agents are commonly used as the first line of treatment for heart failure. One such agent is digoxin, derived from the genus Digitalis, which has been known for centuries but effectively utilized since 1785. However, these cardiac glycosides can have potentially toxic effects due to their mechanism of action, which involves inhibiting Na+/K+-ATPase and increasing contractility. Digoxin is absorbed orally and distributed in various tissues, including the CNS. It has a long...
