摘　　要：目的探讨深静脉留置针与普通静脉留置针在危重病患者CT增强扫描中的应用效果,为危重病患者CT增强扫描提供最佳穿刺工具及方法。方法将采用静脉留置针行CT增强扫描的506例患者随机分为试验组(260例)和对照组(246例)。试验组患者使用深静脉留置针,对照组患者使用常规静脉留置针,比较两组患者造影剂外渗率、一次穿刺成功率及一次增强成功率。结果试验组和对照组患者造影剂外渗率(0.08%与11.79%)比较,差异有统计学意义(P<0.01);一次增强成功率(98.08%与94.31%)比较,差异有统计学意义(P<0.05);而一次穿刺成功率(95.00%与96.34%)比较,差异无统计学意义(P>0.05)。结论 CT增强扫描时配合使用高压注射器,在危重病患者中深静脉留置针明显优于普通静脉留置针,可降低造影剂外渗率,减轻患者的痛苦及保证增强效果。Objective To discuss the effects of intravenous detailed needle and deep venous puncture catheter place- ment in CT enhancement scanning among critically ill patients. Methods A total of 506 critically ill patients underwent spiral CT enhancement scanning were randomly divided into the treatment group （260 cases） and the control group （246 cases） . Deep venous puncture catheter was applied in the treatment group while intravenous detailed needle was applied in the control group. Exosmotic ratio, achievement ratio of first CT enhancement scanning, and achievement ratio of first time puncture were compared between the two groups. Results The exosmotic ratios of contrast medium were significantly different between the two groups （0. 08% vs 11.79%, P 〈0. 01 ） . Achievement ratios of first CT enhancement scanning were significantly different be- tween the two groups （98.08 % vs 94. 31%, P 〈 0. 05 ） . Achievement ratios of first time puncture were not significantly different between the two groups （95.00% vs 95. 34%, P 〉 0. 05） . Conclusion Deep venous puncture catheter placement is superior to intravenous detailed needle among critically ill patients undergoes CT enhancement scanning combined with high pressure syr- inge through decreasing the exosmotic ratios of contrast medium, relieving pain, and ensuring enhancement effects.
