内组织等离子体激活剂 (tPA) 和多尔纳斯α (DNase) 并没有显著改变复杂的流患者的系统凝血. 这表明系统吸收最小,并且在治疗这些具有挑战性的疾病时具有潜在的安全性.
科学领域:
- 肺部病理学 肺部病理学
- 胸部外科手术 胸部外科手术
- 关键护理医学 关键护理医学
背景情况:
- 复杂的肺外泄和肺气带来了重大的临床挑战,往往需要侵入性手术.
- 标准治疗包括抗生素和胸管排水,这可以通过液体粘度来限制.
- 脑内组织等离子体激活剂 (tPA) 和多尔纳斯α (DNase) 在改善输液清除和潜在地避免手术方面表现有前途.
研究的目的:
- 调查tPA和DNase在凝血参数上的潜在系统影响.
- 为了评估tPA和DNase.在内注射后凝血的可测量变化.
主要方法:
- 一项前性观察试点研究,涉及17名患有复杂的肺溢症的患者.
- 凝血参数 (PT,aPTT,D-Dimer,纤维素素,TEG) 测量在内tPA和DNase输注前和后.
- 使用Signed Rank测试进行统计分析,以比较治疗前和治疗后的凝血.
主要成果:
- 在关键的凝血措施中没有观察到显著的变化,包括30分钟后凝血溶解 (Ly30).
- 一名患者出现了腹腔内出血;三名患者需要手术.
- 该研究没有发现系统凝血的统计学上显著的变化.
结论:
- 这项研究是第一个在内tPA和DNase后评估系统凝血变化的研究.
- 这些发现表明,内tPA和DNase不会导致临床上显著的全身吸收.
- 需要进一步的研究,以充分阐明这种治疗方式的安全性.

Extrinsic and Intrinsic Pathways of Hemostasis
The Extrinsic Pathway
The extrinsic pathway of coagulation is typically initiated by tissue damage that exposes blood to tissue factor (TF), a protein released by the damaged tissue cells outside the blood vessels—this interaction with TF triggers biochemical reactions involving specific clotting factors. The key player here is Factor VII, which...

Coagulation
During the coagulation phase, clotting factors, or procoagulants, play a vital role in initiating and progressing the coagulation cascade. This cascade is a series of reactions...
Introduction to Hemostasis
The three phases of hemostasis involve many clotting factors present in plasma and several substances released by platelets and injured tissue cells. It is a fast, localized,...
Formation of the Platelet Plug
As the injured blood vessel contracts, endothelial cells undergo contraction, revealing collagen fibers in the basement membrane and underlying connective tissue. Furthermore, the plasma membrane of endothelial cells becomes adhesive, preparing the site for platelet adhesion. Platelets...
