概括
计算机断层扫描 (CT) 的发现有助于区分外围腔内穿刺和外围腔内血贴片 (EBP) 之前的外围腔穿刺. 在CT上识别外周脂肪和特定的对比标志可靠地证实了针在外周空间的正确放置.
科学领域:
- 放射学 放射学是一门学科.
- 神经外科 神经外科
- 麻醉学 麻醉学
背景情况:
- 在CT导向的外周血补丁 (EBP) 之前,区分外周和内穿刺是主观的,并依赖于操作员的专业知识.
- 精确的针头放置对于成功治疗低脑脊液压头痛的EBP至关重要.
研究的目的:
- 为了调查CT发现区分外围穿刺和脑内穿刺.
- 确定可靠的CT预测器,以成功放置外围注射针在目标CT引导EBP之前.
主要方法:
- 对65名接受CT指导EBP的患者的回顾性分析.
- 分析EBP前CT特征,包括外周脂肪存在和对比注射模式.
- 使用费舍尔精确测试,曼-惠特尼U测试和计算阳性 (PLR) 和阴性概率比率 (NLR) 的统计分析.
主要成果:
- 针尖上的外周脂肪在外周小组 (37.2%) 与内侧小组 (4.5%) 相比显著更高.
- "对比针尖连接"标志 (95.3%外围针对比9.1%内侧针) 和弹形的对比形态 (65.1%外围针对比9.1%内侧针) 强烈表明了外围针的放置.
- "对比针尖连接"显示了最高的PLR (10.49) 和最低的NLR (0.05).
结论:
- 脑电图检测结果,包括外围注射器脂肪,"对比针尖连接"和石形对比,对于确认外围注射器内针位置有价值.
- 这些CT标志提高了CT引导EBP的针位置的准确性,减少了主观性.
- 客观的CT标准提高了外周血液补丁的程序成功率.

01:29Local Anesthetics: Clinical Application as Epidural Anesthesia
452
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...

01:16Local Anesthetics: Clinical Application as Intravenous Regional Anesthesia
452
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.
