目的 观察针刺预处理对CT增强扫描过程中碘造影剂引起的胃肠道反应的影响。方法 选取接受CT增强扫描的患者200例,按随机数字表法随机分为针刺组与对照组,每组100例。对照组在CT增强扫描前4-6 h禁食,针刺组在常规禁食的基础上给予针刺预处理,比较两组CT增强扫描时胃肠道反应情况及CT图像质量。结果 针刺组胃肠道反应发生率、CT图像伪影发生率明显低于对照组（P〈0.05）。结论 针刺预处理可减轻CT增强扫描时胃肠道反应,提高图像质量。

英文摘要：

Objective To discuss the effect of pre-intervention with acupuncture on gastrointestinal reactions caused by iodinated contrast media during computer tomography （CT） enhanced scan. Method Two hundred patients going to receive CT enhanced scan were randomized into an acupuncture group and a control group by using a random number table, 100 cases each. The control group went fasting 4-6 h before the scan, while the acupuncture group received pre-intervention of acupuncture in addition to fasting. The gastrointestinal reactions during CT enhanced scan and the image quality were compared between the two groups. Result The incidence of gastrointestinal reactions and the incidence of CT image artifact in the acupuncture group was significantly lower than that in the control group （P〈0.05）. Conclusion Pre-intervention with acupuncture can reduce the gastrointestinal reactions during CT enhanced scan and improve the quality of image.
