脉冲式预注射生理盐水在CT增强扫描中预防造影剂外渗的研究

Research on prevention of contrast media extravasation by pulsatile pre-injected physiological saline solutions in enhanced CT scanning

目的观察CT增强扫描中脉冲式预注射生理盐水的方法对预防造影剂外渗的效果。方法将符合入组条件的10 200例CT增强扫描的患者随机分为对照组和研究组,每组5 100例,对照组患者给予传统方法预注射生理盐水,研究组患者给予脉冲式预注射生理盐水,在检查结束后,比较两组患者造影剂外渗发生率,调查患者对CT增强扫描的满意度,在研究时间区间内,记录每2个月中两组内各自发生的医患纠纷频次。结果研究组造影剂外渗发生率较对照组明显下降(P <0.05),研究组患者较对照组在整套检查中表现更高满意度(P <0.05),在本研究期间内研究组内患者与医护人员发生医患纠纷的频次明显减少(P <0.05)。结论脉冲式预注射生理盐水可有效减少CT增强扫描造影剂外渗发生率,提高CT增强扫描检查的满意度,具有重要的临床应用价值。

Objective Observe the effect of pulsatile pre-injected physiological saline solutions in enhanced CT scanning to prevent contrast media extravasation. Methods 10 200 patients who meet the enrollment criteria with routine enhanced CT scanning in our hospital were selected for the study. They were randomly divided into into a control group and a research group,with 5100 patients in each group. Thepatients in the control group were given physiological saline solutions with traditional methods and the patients in research group were given physiological saline solutions with pulsatile pre-injection. After the examination,the incidence of contrast media extravasation was compared between the two groups,and the satisfaction with enhanced CT scanning was investigated. The frequency of medical disputes between internal patients and medical staff in the two groups was recorded every 2 months within the study period. Results The incidence of contrast media extravasation in the study group was significantly lower than that in the control group(P < 0.05). The patients in the study group showed higher satisfaction than the control group in the entire set of examinations(P < 0.05). The frequency of medical disputes between internal patients and medical staff was significantly reduced(P < 0.05). Conclusion Pulsatile pre-injection physiological saline solutions can effectively reduce the incidence of contrast media extravasation in enhanced CT scanning and improve patients’ satisfaction with enhanced CT scanning,which has important clinical application value.
