Objective To explore and analyze the causes of thrombosis associated with central venous catheter (PICC) implantation through peripheral vein, and to summarize the specific nursing intervention measures. Methods A total of 213 subjects were selected, all of whom were subjected to PICC catheters. Among them, 19 patients with PICC-associated thrombosis were named as the patient group, while the remaining 194 patients without thrombosis were named as the control group. The clinical data of 19 patients with PICC-associated thrombosis were comprehensively analyzed. To summarize the possible causes of PICC-related thrombosis and discuss the relevant nursing measures. Results Gender, tumor location, catheter outer diameter, puncture site, catheter material, catheter insertion smoothness and retention time were compared between the patient group and the control group. According to data analysis, there were significant differences in catheter material and catheter insertion smoothness between the two groups (P < 0.05). Conclusion The material of catheter and the smoothness of catheter placement are the main causes of PICC-related thrombosis. We should pay more attention to the selection of catheter materials and the improvement of catheter placement skills.
