| Objective To explore the risk factors of upper limb venous thrombosis in long-term bedridden patients with PICC catheterization.Methods A total of 1100 patients were performed PICC in our hospital from January 2019 to October 2020.Clinical data of 80 of them were selected for retrospective analysis and divided into thrombotic group (n=22)and non-thrombotic group(n=58) according to the occurrence of upper limb venous thrombosis.The general information and clinical data of the patients were recorded,and the risk factors of upper limb venous thrombosis were analyzed.Results ①There was a higher incidence of thrombosis in patients with the following factors:Diabetes,NRS 2002≥3 points,APACHE Ⅱ≥8 points,history of PICC catheter,history of chemotherapy,catheter blockage,catheter associated infection,catheter displacement after catheterization,increased TG,TC and D-dimer.There was a lower incidence of thrombosis in patients who took anticoagulants orally.The differences were statistically significant (P<0.05).②Diabetes,NRS 2002≥3 points,APACHE Ⅱ≥8 points,history of PICC catheter,history of chemotherapy,catheter blockage,catheter associated infection,catheter displacement after catheterization,increased TG,TC and D-dimer were independent risk factors for upper limb venous thrombosis in long-term bedridden patients with PICC catheterization,while orally taking anticoagulants was a protective factor (P<0.05).Conclusion Long-term bedridden patients with PICC catheterization should pay attention to prevent thrombosis.Operation specifications should be strictly followed during PICC catheterization to reduce the risk of related thrombosis. |
