摘　　要：目的:探讨链霉蛋白酶颗粒对微探头超声内镜(MPS)图像清晰度的影响。方法:将40例行胃MPS检查患者分为两组:利多卡因组19例,检查前10 min服用利多卡因胶浆10 ml;联合组21例,在服用利多卡因胶浆基础上,检查前20 min加服链霉蛋白酶颗粒。观察两组患者内镜可见度、超声内镜图像清晰度及操作完成时间。结果:联合组内镜可见度评分及超声图像清晰度评分均明显高于利多卡因组(P<0.01),操作完成时间短于利多卡因组(P<0.01)。结论:链霉蛋白酶可提高胃内清洁度,增加MPS图像的清晰度,减少检查操作时间,值得临床推广使用。Objective： To explore the effects of premedication with pronase in miniature probe scanner （MPS）. Methods：A total of 40 patients who accepted MPS in our hospital were divided into two groups： lidocaine group（ 19 cases） and combination group（21 cases）. Lidocaine group had oral lidocaine hydroehloride mucilage 10 ml 10 min before the examination and combination group took the same dose of lidocaine hydrochloride mucilage 10 min and 20 000 unit pronase 20 min before MPS. The visibility scores of image in MPS and gastroscope, the operation time those of lidocaine group （P 〈 0. 01 ）. Conclusion： Premedication with pronase in MPS can effectively improve image visibility and reduces the operation time and is worth applying and recommending.
