概括
优化患者控制的止痛疗法 (PCA) 与背景输液 (BI) 改善了癌症疼痛的静脉注射吗啡定位. 与传统方法相比,这种方法提供了更快,更耐受的疼痛缓解.
科学领域:
- 在瘤学瘤学.
- 疼痛管理 疼痛管理
- 药理学 药理学是指药理学的学科.
背景情况:
- 癌症疼痛管理仍然是一个挑战,对优化患者控制止痛疗法 (PCA) 输注率的研究有限.
- 静脉注射 (IV) 吗啡是一种常见的止痛药,但有效的定位对于管理严重的癌症疼痛至关重要.
研究的目的:
- 评估优化背景输液 (BI) 方法的有效性和安全性,与PCA相结合,用于癌症患者的IV吗啡定位.
- 为了比较优化的PCA-BI方法与用于管理癌症相关疼痛的常规定位策略.
主要方法:
- 进行了一项随机对照试验,涉及44名患有无控制疼痛的固体瘤患者.
- 患者通过自动调整的PCA-BI系统或医务人员的常规定位接受了IV吗啡.
- 衡量的主要结局是突破性疼痛事件的每日频率 (数值评分尺度≥4).
主要成果:
- PCA-BI组在24小时内显示突破性疼痛投诉的显著减少 (0 vs. 3次/天,P=.012) 和较低的非响应率 (21% vs. 55%,P=.048).

One-Compartment Model: IV Infusion
150
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...

Local Anesthetics: Clinical Application as Intravenous Regional Anesthesia
355
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.

Combination Therapies and Personalized Medicine
4.8K
Combining two or more treatment methods increases the life span of cancer patients while reducing damage to vital organs or tissue from the overuse of a single treatment. Combination therapy also targets different cancer-inducing pathways, thus reducing the chances of developing resistance to treatment.
The combination of the drug acetazolamide and sulforaphane is a good example of combination therapy to treat cancer. The cells in the interior of a large tumor often die due to the hypoxic and...
