概括

使用Vieussens (VV) 的新技术可以帮助可视化马歇尔静脉 (VOM) 用于心房动移除中乙醇输注 (EIVOM). 然而,这种方法并没有改善除结果.

科学领域:

心脏病学心脏病学
电子生理学电子生理学
医疗器械医疗器械

背景情况:

马歇尔静脉中乙醇输液 (EIVOM) 是对心房 (AF) 的有限治疗方法,当VOM看不到时.
冠状动脉鼻静脉扫描仅在67%的经历了 mitra isthmus 移除的患者中可视化 VOM.

研究的目的:

评估将导线推进到以前未被可视化的马歇尔脉 (VOMs) 的可行性.
为了扩大马歇尔静脉 (EIVOM) 中乙醇输液在AF患者中对 mitra isthmus 移除的效用.

主要方法:

在Vieussens (VV) 处使用导线和双同轴导导导管技术来定位非可视化的VOM.
如果成功识别了VOM入口,则执行EIVOM.
包括249名接受了 mitra isthmus 移除的AF患者.

主要成果:

在67%的患者中,VOM通过冠状动脉鼻静脉扫描可视化.
一个导线成功地在18%的剩余患者中识别了非可视化的VOM.
在视觉化和非视觉化VOM组中,超过90%的患者实现了完整的 mitra isthmus线阻塞,AF复发没有显著差异.

结论:

维森斯门 (VV) 可以作为改善EIVOM可行性的里程碑.
这种新的技术并没有提高AF切除结果.
由于样本规模较小,对未披露的VOMs的发现是初步的.

关键词:

心房动是一种心房动.乙醇输注是为了输入乙醇.马歇尔静脉是一种静脉.伴心脉静脉切除术伴心脉静脉切除术维乌森斯门的情况

Two-Compartment Open Model: IV Infusion

Two-Compartment Open Model: IV Infusion

A two-compartment model is a vital tool in pharmacokinetics, providing an essential understanding of drug behavior, especially for those administered via zero-order intravenous infusion. This model outlines two compartments: the central compartment, where elimination occurs, and the peripheral compartment.
The model illustrates the decrease in plasma drug concentration from the central compartment with a specific equation. It shows that under steady-state conditions, the drug's input rate...

Local Anesthetics: Clinical Application as Intravenous Regional Anesthesia

Local Anesthetics: Clinical Application as Intravenous Regional Anesthesia

Intravenous regional anesthesia or the Bier block technique is used to anesthetize a specific limb or extremity. It uses exsanguinated or blood-drained vessels to transport local anesthetics or LAs to the peripheral nerve trunks. Lidocaine without vasoconstrictors like epinephrine is most commonly used for this technique. Other drugs used are prilocaine, ropivacaine, and chloroprocaine. Bupivacaine is not recommended for this technique due to its high cardiac toxicity.
One of the advantages of...

One-Compartment Model: IV Infusion

One-Compartment Model: IV Infusion

Intravenous (IV) infusion is often utilized when continuous and controlled drug delivery is necessary, such as during surgery or in the treatment of chronic diseases. This method offers numerous advantages, including immediate drug action, precise control over dosage, and bypassing the first-pass metabolism.
The one-compartment model for IV infusion uses mathematical equations to describe the rate of change in drug quantity in the body. At steady-state or infusion equilibrium, the drug input...
