PICC相关性血栓形成因素及护理干预研究进展

摘要

综述经外周静脉置入中心静脉置管(PICC)相关性血栓的特点、诱发因素以及预防和护理研究进展。指出在PICC相关性血栓的某些诱发因素的研究仍存在一定的争议，无症状的血栓得不到筛查，成为隐匿性血栓。因此有必要对 PICC置管的病人定期进行血栓筛查，识别早期小血栓；对于存在PICC相关性血栓形成的高危因素病人应及时做好血栓的预防干预措施。%This paper reviews the features,predisposing factors,prevention and nursing care of thrombus associ-ated with peripherally inserted central catheter (PICC).Points out that some predisposing factors in the PICC related thrombus research is still controversial;asymptomatic thrombus cannot be screened and become occult thrombosis.Therefore,it is necessary to carry out regular thrombosis screening for patients with PICC in order to identify early microthrombus,take preventive measures for high risk patients with PICC associated throm-bosis.
