摘　　要：目的探讨不同对比剂在能谱CT显示胃癌病变中的护理体会。方法150例胃癌患者按照抛硬币法被平均分为试验组及对照组，其中对照组以口服温开水作为对比剂，试验组以口服20ml碘海醇混入温开水1500ml，观察两者对胃癌的检测情况、不良反应及相应护理。结果能谱CT在采用试验组及对照组两组不同对比剂的情况下，对胃癌的检出率分别为96．0％，85．3％，差异具有统计学意义（X^2=5．042，P〈0．05）。同时，两组患者出现轻度不良反应的比例分别为10．7％，6．7％，差异无统计学意义（x^2=0．785，P〉0．05）。然而，试验组73．3％患者检查后均出现焦虑或抑郁情绪，明显高于对照组的45．3％，差异具有统计学意义（x2=12．185，P〈0．01）。结论碘海醇可作为能谱cT的良好显影剂，提高胃癌的检出率；但检查过程中，相应的护理具有重要意义。Objective To investigate the nursing highlight of different contrast medium to detect gastric lesions by spectral CT. Methods A total of 150 patients with gastric cancer were averagely divided into experimental group and control group according to coin toss. The 20 ml iohexol mixed with 1 500 ml warm water were used in the experimental group, but only oral warm water was used in the control group. The monitored result of gastric cancer, adverse reactions and appropriate care were evaluated. Results The corrective rate of spectral CT for gastric cancer detection in the experimental group and control group were 96.0% and 85.3% respectively, and the difference was significant （ X2 = 5. 042 ,P 〈 0.05 ）. Meanwhile, the proportion of adverse reactions in the experimental group and control group were 10.7% （8/75） and 6.7% （5/75）, but the difference was not statistically significant （X2 = 0. 785, P 〉 0. 05）. However, 73. 3% patients in the experimental group underwent anxiety or depression, which was significantly higher than that in the control group （45.3%）, with a statistically significant difference （ X2 = 12. 185, P 〈 0.01 ）. Conclusions Iohexol can be used as a good developer spectrum of spectral CT, which may also improve the detection rate of gastric cancer. Meanwhile, corresponding nursing is also important during the process.
