概括

一个新的几何模型简化了使用CT扫描进行外周血液瘤 (EDH) 体积估计. 建议7厘米的长度作为外科疏散的门,有助于治疗严重的脑损伤.

科学领域:

神经外科神经外科
放射学放射学是一门学科.
医疗成像医学成像

背景情况:

外周出血瘤 (EDH) 是创伤后的双凸形状的内质.
计算机断层扫描 (CT) 用于EDH诊断,其体积对于治疗决策至关重要.
目前的体积估计方法 (例如,ABC/2) 假定圆形,而不是双凸EDH形态.

研究的目的:

开发一个简化的几何模型,模拟EDHs的双凸形状,使用两个球形帽子.
为估计EDH体积提供一种更准确,更适用于临床的方法.
建立基于EDH尺寸的手术疏散的潜在门.

主要方法:

导出了与球半径,球顶高度和基圆半径相关的公式,以模拟EDH几何.
使用球形盖模型计算EDH体积,并与传统的ABC公式进行比较.
构建了一个查找表,以简化体量估计,并确定了关键的预测参数.

主要成果:

拟议的几何模型使用14个CT图像集在验证中准确预测EDH体积.
该模型简化了ABC方法,将所需的测量从3个减少到1个 (血长度).
超过7厘米长的EDH预计占据超过30毫升的内体积.

结论:

这种新型模型为EDH体积估计提供了一种简化方法,减少了临床评估的复杂性.
推7厘米长度作为EDHs外科疏散的门.
这种加速决策对于管理创伤性脑损伤至关重要;需要进一步验证.

Local Anesthetics: Clinical Application as Epidural Anesthesia

Epidural anesthetics are administered in the fat-filled epidural space, the outermost part of the spinal canal. This technique is commonly employed for pain management and anesthesia during lower abdomen and pelvis surgeries or labor and delivery.
Since epidural anesthetics can be infused through an epidural catheter, all types of drugs, including short-acting ones, can be administered. Chloroprocaine and lidocaine are examples of short and long-duration anesthetics, respectively. Bupivacaine...
