Abstract: Objective: To explore the influencing factors of PICC catheter misplacement rate in the neonatal surgery department, and provide references for better catheterization in the future. Methods: We retrospectively reviewed the catheterization of 208 neonates in our hospital from 2017 to 2018, and analyzed the relevant factors using binary logistic regression analysis. Results: The rate of PICC catheter misplacement in the neonatal surgery department was 16.83%. The regression analysis showed that thoracic diseases were the risk factors of catheter misplacement, and the rate of successful catheterization could be increased by inserting through the right basilic vein. Conclusion: Basilic vein is preferred for intravenous catheterization in the neonatal surgery department, and it is easier to reach the target position by inserting the catheter from the right side. For children with thoracic diseases, 1-2 alternative peripheral blood vessels of different sites should be prepared before puncture in case of need.
