摘要目的 探讨耐高压输液港在CT增强扫描检查中的应用效果.方法 选取2017年9月至2018年9月行化疗后需进行CT增强扫描检查的肿瘤患者220例,采用便利抽样的方法分为观察组和对照组各110例.观察组经输液港注入造影剂进行CT增强扫描检查,对照组使用普通留置针(贝朗安全型静脉留置针22 G)注入造影剂进行CT增强扫描检查,比较2组患者行CT增强扫描检查过程中造影剂外渗发生率、护理耗时及患者满意度的差异.结果 观察组患者CT造影检查后药物外渗发生率为0,对照组为9.1%(10/110),2组比较差异有统计学意义(χ2=10.476,P=0.015).观察组患者CT增强扫描护理耗时(2.60 ± 0.15)min/次,对照组为(5.60 ± 5.29)min/次,2组比较差异有统计学意义(t=5.934,P=0.000).观察组患者对静脉治疗满意、较满意、不满意分别为105、5、0例,对照组分别为80、10、20例,2组比较差异有统计学意义(Z=-12.695,P=0.000).结论 肿瘤患者通过耐高压输液港行增强CT扫描检查,能降低造影剂外渗的发生率,减少护理时数,提高患者的满意度.

abstractsObjective To investigate the application effect of Power port in contrast-enhanced CT scans. Methods Totally 220 cancer patients who needed contrast- enhanced CT scans after chemotherapy were selected in Changhai hospital From September 2017 to September 2018, including 110 cases in the observation group and 110 cases in the control group with convenient sampling method. The observation group was injected contrast medium through Power port for CT scans. Contrast medium was injected into the control group by 22G of Peripheral venous access devices (Introcan?). The incidence of contrast medium exosmosis, nursing time and patient satisfaction were compared between the two groups. Results The incidence of extravasation of contrast medium in the observation group was 0, lower than that in the control group 9.1% (10/110), the difference was significant(χ2=10.476,P=0.015); the nursing time in the observation group was (2.60 ±0.15) minutes per time, which was lower than that in the control group (5.60 ± 5.29) minutes per time), the difference was significant (t=5.934,P =0.000); the patient satisfaction in the observation group was higher than that in the control group, the difference was statistically significant (Z=-12.695, P=0.000). Conclusions Contrast medium injection through Power port for CT scans can reduce the incidence of contrast medium exosmosis, reduce nursing hours and improve patient satisfaction.
