目的:探讨高压注射器在CT增强扫描中的临床应用效果与护理体会。方法:选取阳江市人民医院影像科于2015年1月至2015年12月收治的135例肺动脉血栓栓塞患者,所有患者均应用高压注射器进行CT增强扫描,对其检查结果与护理措施进行回顾性分析。结果:本组135例患者均顺利完成CT增强扫描,且获得高质量、高清晰度图像,其中17例在采用高压注射器注药时出现一过性周身发热、恶心,经护理后症状消失;5例患者扫描后出现皮肤瘙痒、荨麻疹等皮肤过敏反应,遵医嘱给予氯苯吡胺(扑尔敏)10 mg与钙剂口服,10~20 min后症状均有明显缓解;扫描期间共同发生渗漏2例,局部肿胀1例,未出现空气栓塞、静脉炎、心脑血管意外以及造影剂过敏等严重不良反应。结论:在CT增强扫描中应用高压注射器注药,可以保证图像的质量与清晰度,通过针对性的护理措施能够有效控制不良反应的发生,提高安全性。
Objective: To investigate the clinical effect and nursing experience of high-pressure syringe in CT enhanced scanning. Methods: Thirty-five patients with pulmonary thromboembolism admitted from January 2015 to December 2015 in the Department of Radiology, Yangjiang People’s Hospital were enrolled. All patients underwent CT-enhanced scanning with high-pressure syringes. The examination results and nursing measures were retrospectively analyzed . Results: 135 patients underwent CT scan successfully, and high-quality and high-definition images were obtained. Among them, 17 cases had transient periventricular fever and nausea after injection with high-pressure syringes, and symptoms disappeared after nursing. Cases of patients with skin itching scan, urticaria and other skin allergies, given by chlorpheniramine chlorpheniramine (chlorpheniramine) 10 mg and calcium oral, 10 to 20 min after the symptoms were significantly alleviated; co-occurred during the scan 2 cases of leakage, 1 case of local swelling, no serious adverse reactions such as air embolism, phlebitis, cardiovascular and cerebrovascular accidents and contrast agent allergy. CONCLUSIONS: The injection of high-pressure syringes in CT enhanced scanning can ensure the quality and clarity of images. The targeted nursing measures can effectively control the occurrence of adverse reactions and improve the safety.
