目的比较Y型静脉留置针与直型静脉留置针在CT增强检查中的应用效果,提高CT增强扫描检查的成功率和安全性。方法对采用Y型静脉留置针2 254例(Y型组)患者和采用直型静脉留置针的2 902例(直型组)患者,均取右上肢肘静脉,定专人完成操作,比较两组一次增强造影成功、留置针折叠破裂、造影剂针端帽头侧漏及造影剂外渗发生率。结果直型组一次性CT增强成像成功率显著高于Y型组,留置针折叠破裂、造影剂针端帽头侧漏发生率显著低于Y型组(均P<0.01)。结论病情稳定、中途无需另行用药患者宜选用直型静脉留置针;反之,宜选用Y型留置针。
Objective To compare the effect of Y-type vein indwelling needle and straight vein indwelling needle in CT-enhanced examination and to improve the success rate and safety of CT-enhanced scanning. Methods A total of 2 254 patients (Y group) with Y-type indwelling needle and 2 902 (straight-type patients) patients with a straight IV catheter were selected. An enhanced contrast success, indwelling needle folding rupture, contrast cap needle side cap leakage and contrast agent extravasation. Results The success rate of one-time CT enhanced imaging in the straight group was significantly higher than that in the Y group. The folding and ruptured indwelling needle had a significantly lower incidence of lateral leakage of the caput than the Y group (all P <0.01). Conclusion Stable condition, no need to take another drug in the middle of patients should use straight vein indwelling needle; the other hand, should use Y indwelling needle.
