高压注射器CT增强检查减少对比剂外渗的预防护理

目的探讨CT增强检查减少对比剂外渗的预防护理措施。方法将2015年6月至8月第一扫描室行高压注射器静脉内造影CT增强检查患者4871例作为研究对象，收集和整理4871例患者的临床资料，分析对比剂外渗的不同原因．并采取预防性护理措施。结果4871例患者中，29例患者发生对比剂外渗，表现为局部不同程度肿胀、热痛、麻木，无溃疡、坏死发生。经及时处理均在24h后肿胀消退，恢复正常，无并发症发生。结论由于CT扫描速度快，高压注射器注射压力大．对比剂外渗的概率也相对较高。所以医护人员必须提高警惕，做好增强扫描前后的预防护理工作，做到预防为主，以减少和杜绝对比剂外渗现象的发生，如此才能获得满意的CT增强扫描图像，达到明确诊断、及时诊治的目的。

Objective To study the high pressure syringe CT preventive nursing measures to reduce extravasation of contrast. Methods Our hospital in June 2015-August 2015,1ine of high pressure syringe in 4 871 patients with intravenous contrast enhanced CT examination as the research object,and the collection of the clinical data of 4 871patients, extravasation of contrast analysis of different reasons,and take preventive nursing measures.Results 4 871 cases of patients,29 cases of patients with extravasation of contrast,show the local heat different degree of swelling, pain, numbness,no ulcer,necrosis occurred. After the prompt processing within 24 h after the swelling subsided,returned to normal,no complications occurred.Conclusion Because of a CT scan speed,high pressure syringe injection pressure is big, the probability of extravasation of contrast is relatively high.So medical staff must be vigilant, early good preventive nursing before and after enhancement scanning, prevention first,to reduce and eliminate extravasation of contrast phenomenon occurs,so to get satisfactory CT enhanced scan images,to achieve a clear diagnosis,timely diagnosis and treatment.
