Target disease: |
Hematological diseases (including leukemia, lymphoma, anemia, and coagulation disorders) require long-term chemotherapy and frequent blood sampling. As the primary vascular access, PICC currently lacks standardized blood sampling protocols based on internal volume, and repeated push-pull manipulations may cause hemolysis, catheter occlusion, and infection.

研究目的: |
本研究基于基于血流动力学理论下SVC高血流速度(2000-2500mL/min)及PICC内容积测定,旨在建立一种精准、规范的PICC采血流程。通过体外实验测定导管内容积并验证血常规准确性,探究以“导管内容积”为基准的最佳抽推循环次数与最少单次抽推量,从而将建立血液科PICC内采血的标准化操作。该流程旨在降低因反复抽推导致的溶血、导管损伤(堵管、感染)等并发症风险,最终达到提升导管使用寿命、患者安全及护理质量的目标,为PICC采血提供循证依据。 |

Objectives of Study: |
This study is based on the hemodynamic theory of superior vena cava (SVC) high blood flow velocity (2000–2500 mL/min) and PICC internal volume measurement, aiming to establish a precise and standardized PICC blood sampling protocol. Through in vitro experiments to determine catheter internal volume and validate complete blood count accuracy, we will explore the optimal number of push-pull cycles and the minimum single push-pull volume based on "catheter internal volume," thereby establishing standardized procedures for intracatheter blood sampling in hematology departments. This protocol aims to reduce the risk of complications such as hemolysis and catheter damage (occlusion, infection) caused by repeated push-pull manipulation, ultimately achieving the goals of extending catheter lifespan, ensuring patient safety, and improving nursing quality, while providing evidence-based support for PICC blood sampling. |
