耐高压PICC在肿瘤患者腹部CT增强中的应用研究

Application of High Pressure PICC Catheter in Abdominal CT Enhancement of Tumor Patients

目的分析耐高压经外周静脉置入中心静脉导管(PICC)在肿瘤患者腹部CT增强中的应用情况。方法随机选取我院2021年1月至2023年6月期间实施腹部CT增强扫描的肿瘤患者300例,按随机数字表法分为例数相同的3组,其中对照组100例实施常规静脉留置针予以对比剂团注;观察1组(n=100)、观察2组(n=100)均用耐高压PICC导管予以对比剂团注,根据对比剂说明书参照剂量以及患者实际特点、医院常规使用情况,将对比剂用量分别设置为1.3、1.1 mL/kg;对比三组CT增强扫描并发症、图像质量等。结果总的增强扫描不良事件发生率方面,观察1组、2组明显低于对照组(P<0.05),而1、2组相比差异无统计学意义(P>0.05)。观察1组、2组从进入检查室至CT扫描的时间、CT扫描结束至按压无出血的时间、整体耗时均短于对照组,图像质量、噪声及锐利度评分均高于对照组(P<0.05),而观察1、2组相比差异无统计学意义(P>0.05)。三组患者CT增强扫描结束后未出现导管高压注射损坏及导管堵塞的情况。观察2组的对比剂用量低于观察1组、对照组(P<0.05)。结论肿瘤患者应用耐高压PICC导管并联合低对比剂注射用量行腹部CT增强,优化了CT增强的检查流程,提高了患者的检查舒适度,减少不良事件的发生,值得临床推广。

Objective To analyze the application of high-pressure resistant peripherally inserted central venous catheter(PICC)in abdominal CT enhancement of tumor patients.Methods 300 tumor patients who underwent abdominal CT enhanced scanning in our hospital from January 2021 to June 2023 were randomly selected and divided into groups with the same number of cases according to the principle of random number table allocation.Among them,100 patients in the control group received conventional intravenous indwelling needle and contrast agent injection;Observation group 1(n=100)and observation group 2(n=100)were both injected with contrast agent using high-pressure PICC catheters.According to the reference dose in the contrast agent manual,as well as the actual characteristics of the patient and hospital use,the contrast agent dosage was set to 1.3 and 1.1 mL/kg,respectively;Compare the complications and image quality of three groups of CT enhanced scans.Results In terms of the overall incidence of adverse events during enhanced scanning,the observation groups 1 and 2 were significantly lower than the control group(P<0.05),while there was no significant difference between the 1 and 2 groups(P>0.05).The time from entering the examination room to CT scanning,the time from CT scanning to no bleeding during pressing,and the overall time consumption of Group 1 and Group 2 were observed to be shorter than those of the control group.The image quality,noise,and sharpness scores were higher than those of the control group(P<0.05),while there was no significant difference between Group 1 and Group 2(P>0.05).Three groups of patients did not show any damage or blockage of the catheter due to high-pressure injection after CT enhanced scanning.The dosage of contrast agent in observation group 2 was lower than that in observation group 1 and control group(P<0.05).Conclusion The use of high-pressure PICC catheters combined with low contrast agent injection for abdominal CT enhance ment in tumor patients optimizes the examination process,improves patient comfort,and reduces the occurrence of adverse events,which is worthy of clinical promotion.
