概括
一种具有通路可视化的新型超声波设备显著提高了外周静脉导管 (PIVC) 准确性和在基板测试中的成功率. 这项技术有望改善难以静脉输入 (DIVA) 患者的管.
科学领域:
- 医疗器械 医疗器械
- 超声波技术 超声波技术 超声波技术
- 血管接入 血管接入
背景情况:
- 第一次通过外周静脉导管 (PIVC) 插入失败率可能高达40%,通常是由于静脉局部化的挑战.
- 成功的后续尝试在很大程度上依赖于精确的静脉识别,特别是在难以静脉输入 (DIVA) 的患者中.
研究的目的:
- 评估一款新型超声波设备,其特点是冠状管路可视化,以提高PIVC插入精度.
- 在未经训练的用户中,比较本设备与传统点位定位 (单个超声波) 的有效性.
主要方法:
- 一项基板研究涉及14名未经培训的研究人员,他们将PIVC插入到幻影模型中.
- 利用路径可视化和点定位技术,收集关于第一次尝试成功率,管尖端到容器距离和角度对齐的数据.
- 研究了诸如管熟悉度和握力技术等用户因素,以告知原型开发.
主要成果:
- 与点本地化 (71.4%) 相比,路径可视化产生了更高的第一通成功率 (85.7%),有效地将失败率减半.
- 通过路径可视化观察到与头到容器距离 (1.91毫米对比4.21毫米,p <.004) 和角度对齐 (3.49°对比12.50°,p <.001) 的距离,观察到显著提高的准确性.
结论:
- 与点定位相比,冠状管路径可视化显著提高了PIVC放置精度,成功率和针到容器对齐.
- 该设备有可能改善DIVA患者的管成功.
- 需要进一步的研究来比较冠状管道可视化与传统横向可视化 (手持超声波).

Local Anesthetics: Clinical Application as Intravenous Regional Anesthesia
1.1K
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.

Peripheral Arterial Disease II: Clinical Manifestations and Diagnostic Evaluation
339
Clinical manifestationsPeripheral Arterial Disease (PAD) manifests through a range of symptoms, from the characteristic intermittent claudication to atypical presentations and severe complications in advanced stages. Intermittent claudication, a hallmark symptom of PAD, presents as exercise-induced muscle pain that typically resolves within minutes of rest. This pain is reproducible and stems from inadequate blood flow, leading to the accumulation of lactic acid produced during anaerobic...
