摘要目的:探讨CT室-病区一体化护理模式在CT冠状动脉血管成像患者检查前准备中的应用效果。方法:采用便利抽样法选取2017年6—12月在本院心内科住院拟行CT冠状动脉血管成像检查患者200例为对照组，2018年1—6月同法选取200例为观察组。对照组采用预约登记、健康宣教等常规准备程序；观察组采用CT室-病区一体化护理模式，即成立CT室-病区一体化护理小组，先由CT室护理人员对小组成员进行心脏CTA成像检查前准备工作专业知识培训，并经考核合格后上岗。病区小组成员自医生开出检查医嘱后即对患者进行检查前的心率控制管理、呼吸训练指导等检查前的准备工作。比较两组患者进入CT室静息15 min后心率达标和呼吸屏气配合达标情况；比较两组患者再服药率及检查过程中心率波动幅度≥10 bpm的发生率；比较两组患者检查前准备时间和实际检查时间及两组患者图像质量评价以及两组患者服务满意度。结果:观察组患者进入CT室后心率达标率、呼吸屏气配合达标率明显高于对照组（83.00%、89.00%比72.50%、80.00%），两组比较差异均有统计学意义（均 P<0.05）；观察组患者再服药率也明显低于对照组（15.00%比34.00%），检查过程中观察组心率波动幅度>10 bpm的发生率也显著低于对照组（14.00%比37.50%），两组比较差异有统计学意义（均 P<0.01）。观察组患者检查前准备时间、实际检查时间明显短于对照组[（35.60±1.80）min、（8.80±1.50）min比（55.20±3.60）min、（10.60±1.40）min]，两组比较差异均有统计学意义（均 P<0.01）；观察组患者图像质量总体合格率、患者满意度明显高于对照组（91.00%、97.50%比79.00%、88.00%），差异均有统计学意义（均 P<0.01）。 结论:CT室-病区一体化护理模式可明显提高CT冠状动脉血管成像患者的配合状态，降低再服药率，缩短准备和检查时间，有效提高图像质量，提高患者服务满意度，值得临床推广应用。

abstractsObjective:To explore the effect of integrated nursing model of CT room and ward in the preparation of patients before cardiac CT coronary angiography examination.Methods:200 cases of CT coronary angiography in our hospital from June 2017 to December 2017 were selected as control group by convenient sampling method, and 200 cases were selected as observation group from January 2018 to June 2018 by the same method. The control group received conventional preparation procedure including booking registration and health education; the observation group received CT room-ward integrated nursing model, i.e., CT room-ward integrated nursing group was established, and the pre-examination preparations including patients' heart rate control management and breathing training guidance were implemented by the members of the ward group after doctors giving advices. The percent of pass of heart rate and breath holding coordination of the two groups after 15 minutes of rest in CT room were compared, the rate of taking medicine again and the rate of heart rate fluctuation >10 bpm during the examination were compared, the preparation time before examination and actual examination time of the two groups were compared, the image quality of the two groups were evaluated, and the service satisfaction of the two groups were compared.Results:The percent of pass of heart rate and breath holding coordination in the observation group were significantly higher than those in the control group (83.00%, 89.00%, and 72.50%, 80.00%), with statistically significant differences between the two groups (all P<0.05). The rate of taking medicine again in the observation group was significantly lower than that in the control group (15.00% vs. 34.00%), the incidence of heart rate fluctuation >10 bpm in the observation group during the examination was significantly lower than that in the control group (14.00% vs. 37.50%), with statistically significant differences between the two groups ( P<0.05 or P<0.01). The preparation time before examination and actual examination time of the observation group were significantly shorter than those of the control group [(35.60±1.80) min, (8.80±1.50) min, and (55.20±3.60) min, (10.60±1.40) min], with statistically significant differences between the two groups (all P<0.01). The percent of pass of image quality and patient satisfaction in the observation group were significantly higher than those in the control group (91.00%, 97.50%, and 79.00%, 88.00%), with statistically significant differences between the two groups (all P<0.01). Conclusion:CT room-ward integrated nursing model can significantly improve the cooperation degree of patients with cardiac CT coronary angiography, reduce the rate of re-taking drugs, shorten the preparation and examination time, effectively improve image quality, and improve patient service satisfaction, which is worthy of clinical application.
