摘要
目的探讨增强CT扫描时气体随对比剂入血引起气体栓塞的可能性及气泡分布规律,并提出护理对策。方法对371例胸部增强CT扫描病人进行回顾性研究,对气体入血的情况、气泡大小、形态及分布位置进行分析。结果肺动脉干组、上腔静脉组、锁骨下静脉组和右头臂静脉组气泡大小比较差异无显著性(P>0.05);4组产生气泡大小的95%置信区间分别为2.97～4.01、2.55～3.44、2.95～3.95、1.84～5.67mm。对出现气泡的107例病人进行追踪回访显示均无肺栓塞发生。结论气泡微量入血时不会对人体造成严重伤害,应规范护理操作杜绝肺栓塞发生。
Objective To explore the possibility of air embolism caused by air bubbles getting into blood circulation fol- lowing contrast agent and the distribution of the bubbles and provide its nursing care. Methods A retrospective review was done in 371 patients undergoing chest enhanced scan, the bubbles in the blood stream were analyzed with regard to their size, form and distribution. Results A comparison of the size of bubbles among groups of the pulmonary trunk, superior vena cava, subclavian vein and brachiocephalic trunk showed no significant differences. The 95% confidence interval of the air bubble size in the four groups was 2.97--4.01, 2.55--3.44, 2.95--3.95 and 1.84--5.67 ram, respectively. A follow-up in the 107 patients with bubbles in the blood no pulmonary embolism was found. Conclusion Tiny air bubble getting in blood circulation does not severely harm hu- man body. A standardized nursing procedure should be carried out to eliminate the occurrence of pulmonary embolism.
