一种新型经鼻内镜与普通胃镜的临床对比研究

A comparative study on a new transnasal gastroscopy and routine gastroscopy

目的探讨Fujifilm EG-530NW经鼻胃镜的临床应用价值。方法295例接受胃镜检查的患者，按检查序号的随机数字表法随机分成普通胃镜组（172例）和新型经鼻胃镜组（123例），观察新型经鼻胃镜组的检查情况，并比较两组患者的血压、心率波动情况以及检查过程中的不适程度差异。结果新型经鼻胃镜组获得的图像与普通胃镜组相似，反转观察无盲区且图像清晰。新型经鼻胃镜组无不适或一般不适的比例明显高于对照组（81．3％比68．6％），差异有统计学意义（P〈0．05）；心率波动亦明显小于普通胃镜组[（7．4±11．6）次／min比（11．t±14．6）次／min]，差异有统计学意义（P〈0．05）；而血压波动两组间比较差异无统计学意义（P〉0．05）。在年龄较大患者（年龄〉50岁）中，新型经鼻胃镜组心率、血压波动均显著小于普通胃镜组，差异有统计学意义（P〈0．05）。结论Fujifilm EG-530NW经鼻胃镜可以获得高质量的图像，较普通胃镜更能减轻患者检查时的不适感，并可减少患者心率与血压的波动，尤其对于年龄较大的患者更具有明显优势，更加安全。

Objective To investigate the clinical value of new transnasal Fujifilm EG-530-NW electronic gastroscope. Methods A total of 295 patients who underwent gastroscopy were randomly divided into 2 groups to receive examination by routine endoscope （ n = 172 ） or Fujifilm EG-530-NW transnasal endo- scope （n = 123）. The fluctuation of heart rate, blood pressure and compliance during the examination were recorded and compared between the two groups. Results The new Fujifilm EG-530-NW could obtain clear images with same quality of routine gastroscope. The heart rate change and visual analog pain score in pa- tients from EG-530-NW gastroscope group were significantly lower than those of routine gastroscope group （ P 〈 0.05 ）. No significant difference in blood pressure fluctuation was observed between the two groups. In patients older than 50 years, the fluctuations of heart rate and blood pressure in EG-530-NW group were significantly less than those of routine gastroscope group. Conclusion Fujifilm EG-530-NW gastroscope can get high quality image with less influence on heart rate and blood pressure fluctuation, which is more signifi- cant in older patients.
