CT高压增强扫描局部渗漏高危因素分析

The Analysis about Jigh-dangerous Factors of Local Leakage in CT Pressure Enhancement Scan

目的本文旨在探讨CT高压注射增强渗漏的高危因素,以达到预防渗漏、减少对患者的损伤的目的。方法分析CT增强患者共6136人,按病种(糖尿病、动脉硬化、高血压、恶液质、配合不良和无特殊)进行分组,并规定轻、中、重渗漏程度。计数各组渗漏总数与不同程度渗漏的百分比。按注射速率分组,计数各组不同速度渗漏发生的百分比。对数据进行chi-square检验。结果恶液质患者肿胀总百分比最高,为15.42%,糖尿病+动脉硬化次之,糖尿病、动脉硬化及高血压肿胀百分比较低,无特殊者肿胀百分比最低,占0.16%,Chi-square值为16.63%,p=0.005<0.01,数据具有极显著性意义。轻度渗漏中恶液质组肿胀总百分比为12.47%,无特殊者肿胀百分比最低,占0.16%,Chi-square值为14.40%,p=0.013<0.05,数据具有显著性意义。其余数据无统计学意义。注射速度与肿胀发生率无显著性的差异,p均>0.05。结论本文结果提示CT高压注射存在渗漏的高危因素,重点对高危因素的预防,对在日常工作具有指导作用。

Objective To evaluate the high-gangerous factors about local leakage in CT pressure enhancement scanning, in order to prevent the incident of leakage and injuring patients. Methods Total 6136 patients experienced CT pressure enhancement were analysed that were grouped according to disease such as diabetes, arteriosclerosis, hypertension, cachexia, ill-cooperation and nothing. Light, middle.and severe degrees of leakage were constituted. The percent rates of leakage number in different groups and leakage degrees were counted. Again, grouping according to injective velocity were done and percent rates of leakage in different velocity were counted. The data were tested by chi-square. Results The percent rate of leakage in cachexia was highest（15.42%）, of diabetes adding arteriosclerosis was second, of iabetes and arteriosclerosis were lower, of nothing was lowest（0.16%）. The data were tested by chi-square that chi-square value was 16.63%, p=0.005 〈 0.01. The testing result had extremely distinct significance. The percent rate of light leakage in cachexia was 12.47%, The percent rate in nothing was lowest（0.16%）, that chi-square value was 12.47%, p=0.013 〈 0.05, The testing result had distinct significance. The rest data hadn＇t statistical significance. The percent rates of leakage in injective velocity also hadn＇ t statistical significance （p 〉 0.05）. Conclusions The results indicated that high-dangerous factors existed in CT pressure enhancement. The taking preventing steps to the high- dangerous factors could play a important part in daily work.
