Abstract：Objective To explore the causes and preventive measures of a large number of contrast agent overflowing in CT enhanced scanning. Methods A total of 2500 patients with CT enhanced scan in Beijing Shijitan Hospital, Capital Medical University from July 2013 to November 2015 were selected to observe whether a large number of contrast agent spillovers appeared during the scan. Through single factor description analysis and multivariate Logistic regression analysis, the causes of contrast agent overflow were analyzed, and preventive measures were discussed. Results A large number of contrast agent overflows were found in 21(0.84%) of 2500 patients after CT enhanced scan. Single factor analysis showed that in the age, disease typ, injection vessel site, injection velocity, osmotic pressure, poor compliance of patients and nurses are not skilled were related to a large number of contrast agent overflowing (P ＜ 0.05). Multivariate Logistic regression analysis showed that age (OR = 1.825), disease type (OR = 2.054), injection velocity (OR = 3.024) and osmotic pressure (OR = 2.687), Compliance (OR = 1.953) and skill level of nurses (OR = 2.547) were independent risk factors affecting the extravasation of a large number of contrast agents. Conclusion The influence factors of a large number of contrast agent spillovers in CT scan are interacted. Strengthening nursing intervention according to the related factors, improve the skill of puncture, improve the security of enhanced scan.
